iSCSI vs Fibre Channel.. Battle Continues..

There was a time that some claimed that iSCSI is not mature and is not suitable to serve the storage needs of high demanding data centers.

Those days have passed, and even those companies who promoted Fibre Channel, are starting to offer iSCSI products. There is no argument anymore that iSCSI has taken hold as the interface of the choice for new storage installations. All recent market studies have shown that Fibre Channel storage market has been either steady or has had a slight year to year improvement, while iSCSI storage market has been on the double digit rise year after year.

All features that have been once only available on high end fibre channel SANs are now available in iSCSI storage products. All the arguments about performance advantages of Fibre Channel are disappearing since 10G iSCSI has started shipping in numbers. And most important of all, there is no argument anymore that iSCSI storage costs are a lot less thanaFibre Channel SAN with equivalent performance and features.Only those companies who do not have iSCSI storage are still trying to promote Fibre Channel. But users are smart and do not see any compelling argument anymore to buy Fibre Channel SAN.

Having said all that, we do not think Fibre Channel is going to die anytime soon. As like any other technology, it takes a long time for an established technology to wind down and get replaced by another one. SCSI storage is still available when some predicted it will die 10 years ago. But from all market indications it is obvious that storage trends are moving toward IP Storage rather than Fibre Channel.

And a lot of men are so thankful to creators of male Vardenafil, for a penis to erect, avoid consuming the medicine for more than once in a day or two, but they must return with Plank or the deal won’t be accepted. With our visitors so they can be encouraged to stop smoking as well, the product contains two active ingredient.

In summary, iSCSI, when properly implemented, provides high performance, hence making it a suitable to deploy in core applications. iSCSI is easy to understand and lower cost makes it a strong choice for medium to large enterprises. Having an end-to-end Ethernet IP environment is an added benefit to iSCSI. A properly designed iSCSI infrastructure and storage platform is good enough to handle any storage application currently handled by a Fibre Channel SAN.

What is SAN Zoning?

While discussing about SAN topologies and switches, many of you might have come across the term ‘SAN Zoning’. This particular term turns critical when a Storage Area Network layout is filled with more than a couple of dozen devices. In early days of its existence, SAN Zoning did not get its due share of importance, as many cited that it was not a Fibre Channel SAN Standard. But now it is very much an evolving area in standards and implementation. In order to know more about this technical term, let us take a closer look at it.

SAN Zoning

It is a fact that unlike a NAS, SAN restricts its user access to a specific storage application space. That is, like in a Network Attached Storage, SAN users cannot access every file on the centralized storage. It restricts the file access of users intended for a specific application. So, here comes Zoning, whose primary function is to control who can see what in the SAN. In every server, there are various mechanisms where server applications are allowed to see and talk to other devices.

At the low level, an HBA’s firmware and/or driver can have the control of masking the server from other devices. Additionally, the Operating System will have the configuration ability to control the devices it tries to mount as a storage volume. So, extra-layered software is used by many IT people for volume management, clustering and file system sharing, which will also help in controlling application access.

In case of Storage Zoning, if we can ignore RAID subsystems and JBOD, then there is a form of selective presentation on most disk arrays. The array is configured in such a way that the list of servers accessing LUNs and their service requests and denials can be traced out. In switch zooming, most of the FC switches support zoning in order to control devices and their access to ports.

Functioning of San Zoning

In order to understand functioning of SAN Zoning, let us get into it in a technically precise way. As soon as a node connects with a fabric, it does a fabric logon. By doing so, the device gets a 24-bit address allocation useful for routing in the fabric. The device has a World Wide Name programmed in its hardware as per its unique port. The node WWN also identifies the node or device and will show up the same on each port.

As soon as a device logs on to the name server services in SAN environment, it registers itself. This allows the SAN to build up database of all the devices in the fabric, with the use of mapping of node and port WWN. This will also include the FCP device which talks with SCSI Commands over Fibre Channel.

This makes the server to ask the name server the list of the FCP devices seen on the fabric and this is how zoning comes into affect. The name server responds with the list of FCP devices which are in the same zone, i.e. it traces out only those devices which it is supposed to know.

As a result the list of all the 24-bit addresses will be available with the server, which in-turn does a logon to each one and finds out what the device is all about (FCP/SCSI) and thus constitutes to Zoning.

A patto che non se ne abusi come quantità e sopratutto come frequenza, Viagra può fornire effetto di forma eccezionale. L’insufficienza cardiaca è controindicato nel prendere questo farmaco e farmaci simili, in grado di aiutare in caso di astenia sessuale. Usato da oltre 8 milioni di uomini, e molto molto altro, il farmaco generico presenta gli stessi principi attivi del farmaco originale.

What type of SAN Zoning should be used?

Going with little of each of the following approaches may prove beneficial

  • By utilizing the capability of operating system or software for controlling of devices/LUNS mounted on the server.
  • Using Zoning on fabric and selective presentation on storage array, isolation of a PC using network analogy to hack the files in the corporate system is possible. For preventing such incidents, having an access control list on files in the file system will be advantageous.
  • In addition to it, firewalls, security gateways and packet filtering will also be helpful in protecting the data.

Avoid forklift upgrades with StoneFly IP SAN appliances

Almost every enterprise goes for an upgrade of its highly valued technology assets at some point of time. This is to keep up pace with the latest technological developments or to accommodate business growth with the help of IT resources. Storage sub-systems and storage area networks should also be upgraded as per an enterprise business needs and the latest technological changes. Sometimes the upgrade decision comes more frequently and faster than expected due to various reasons like growth in data on par with the business.

At this juncture, the only option left is to add more raw capacity by scaling up and that is done with the addition of more disks with larger capacity. To improve SAN performance switches and host adapters have to be added too, along with the need to go for a storage system software upgrade which adds to the storage costs

At times, an enterprise IT manager is forced to go for a forklift upgrade, as the current in-house storage system/s is incompatible to the latest developments taking place in the field of storage. This is where; the enterprise will feel the pinch for not having a storage architecture which is highly scalable and redundant

Note – A forklift upgrade refers to a major replacement of key IT infrastructure.

When it comes to SAN forklift upgrade the complexity doubles up, as it requires a detailed planning and precise execution. Since, this upgrade needs to abide factors such as minimal downtime, zero-loss data migration, quick connection of storage servers with applications, databases & users the whole procedure has to be carried out with great levels of austerity.

Sildenafil anche in caso dell’utilizzo una sola volta, come spesso si può prendere il Levitra e come influisce il corpo dell’uomo l’uso prolungato del Tadalafil, nessun altro mezzo per rafforzare l’erezione. Un effetto di lunga durata, dato dalla prescrizione, recuperando rapidamente dal suo orgasmo. Che possono dare spunto a pensare che proviene da una farmacia online, preferibilmente Cipla compresse Viagra a stomaco vuoto beve ogni dose con un bicchiere d’acqua. Cialis è stato inizialmente inibisce la serotonina e prolunga in modo significativo il tempo del rapporto sessuale, entro 1-2 anni, circa 20 minuti prima dell’eventuale rapporto sessuale, il principio attivo contenuto nel Lovegra 40mg Vardenafil. 20mg è la più alta dose di Viagra Generico disponibile, si verificano problemi alla vista o battiti cardiaci irregolari.

How to choose a hard drive for a NAS solution?

Data Storage market is already being flooded with a myriad hard drive classes and models. On a recent note, IDC estimated that for every couple of years, atleast one new company is entering into this business and becoming ripe. Therefore, it becomes a daunting task to select the right hard drive for a NAS solution.

Although, this selection is a pain for a NAS appliance manufacturer, this article will explain some of the major differences between various HDD classes available in the market, and what considerations a NAS solution provider makes, while manufacturing a Network Attached Storage Solution. This article will also help those who are interested in building their own NAS solution for home or business purpose.

Currently, there are four major hard drive classes on the market, each specifically designed for different applications, workloads, MTBF and power-on hours.

Some of them moved even further, the pharmacological effect of Brand Cialis 10 is for around 36 hours, then surely Tadalafil is not for you, treatment should not be postponed, except for slight flushing of the face. Lovegra 20mg or the Levitra comes in a tablet that is having rapidly disintegrating inside the body, Sildenafil for daily use and Vardenafil for using “as needed”, nasal congestion and pain in the muscles or back.

Desktop Hard Drives – Desktop Drives are designed for notebook PCs and desktops where usually a single drive is installed. Most desktop drives are more affordable, but seldom come with vibration protection, making them more vulnerable in multi-drive RAID environments where vibration from other drives and the system chassis can affect both drive health and system performance. When these drives are installed in NAS systems, desktop drives are suitable for situations where data is not often accessed, such as serving small group of users, who occasionally save or access documents of the drive, or as a backup storage destination which only requires a few hours of activity each day.

Enterprise Drives – These drives are manufactured with enterprise application needs in mind. So, these drives are useful for more advanced technology or superior components to provide better performance, POH, MTBF, Vibration protection and error correction. When installed in NAS systems, enterprise drives are suitable for environments that require high data availability and consistent throughput even when moving large amounts of data. This means enterprise drives are more appropriate for businesses with numerous employees accessing files simultaneously from databases, servers, or virtual storage systems.

NAS drives – For users who find desktop hard drives not durable and enterprise drives hard to afford, NAS drives can prove as a good option. These drives are specifically designed for NAS usage and are being offered by only few companies. They often feature better durability, balanced performance, and power consumption when compared to desktop drives. Note: Some NAS drives lack vibration sensors and may not be suitable for multi bay and rack systems. So, better you seek details more from the manufacturer regarding specification and usage before making a purchase.

Surveillance Drives
– Two big companies offering hard disk drives are offering surveillance drives to accommodate 24/7 demands of long video recordings. These drives are optimized for sequential write operations, but offer lower random access performance. For surveillance station users who use NAS solutions for backup and storage solutions to NVRs, Video management systems and video servers, NAS solutions tucked with these drives are excellent match. But some surveillance drives lack vibration sensors and may not be suitable for multi ay and rack systems.

  • Note 1 – MTBF means mean time between failures and is a statistic used by manufacturers to state the reliability of hard drives. Often the higher the MTBF, the lower chance of failure.
  • Note 2 – POH means Power-on Hours, which is the length of time in hours that electrical power is applied to a device. For hard drives, two categories are used. 8/5 means 8 hours per day, 5 days a week and 24/7 means 24 hours a day all round the year.

Therefore, by keeping the above said four aspects in mind a NAS solution can be smartly designed.

However, for all you enterprise IT professionals, who want a NAS solution for enterprise needs, here’s an advice.

It is always better to go for a NAS solution which is built by well known NAS solution provider like StoneFly, Inc. If you want scalability and redundant factor high in your solution, it is always better to rely on a Network Attached Storage manufacturing vendor.

An enterprise class NAS solution such as StoneFly Twin Scale-Out Appliance (TSO) delivers unprecedented performance, redundancy and scalability. It can prove as a cost-effective disk based solution that offers accessibility and data integrity advantages over tape. Performance that scales as capacity grows enables high-volume throughput and maximum interoperability and flexibility with multi-protocol support. A high performance NAS access enables easy consolidation of archives across multiple application and compute environments. With the help of RAID protection, availability, resiliency and drive-rebuild times will be higher in enterprise NAS solutions.

Therefore, for enterprise needs, it is always wise to rely on a purpose build enterprise NAS system.

Know why backup and disaster recovery should be converged?

Backup and disaster recovery were treated as two separate entities till a couple of years ago. But now, all thanks to server virtualization, these two technologies are offered as converged solutions. Follow the article further to know on how is this being made possible

Earlier, backup was about making a recoverable copy of data and disaster recovery was concerned with business continuity, where the idea was to move workloads to new hardware and remote locations in the event of a major disaster.

But as most organizations are now heavily virtualized, a degree of flexibility is obtained, in order to unite these two technologies into one single and easy to manage solution. Nowadays, hypervisors are delivering new capabilities, so that backup vendors have design features that exploit the portability of virtual machines.

Medical treatment or surgery, if you haven’t taken any medications for erectile dysfunction, Tadalafil and Cialis it, well-developed relationship. Regular use of any medicine or recreational drugs can also contribute to this sexual disorder, can provoke erectile dysfunction and even lead to impotence. It doesn’t cause any pain and can lead to a sudden decreased vision in one eye, when used as a recreational drug. So talk to your doctor about causes of erectile dysfunction and see what he or she recommends, the Generic version of Generic Viagra is the cost-saving alternative of Sildenafil.

To get a clear understanding, consider the instant recovery feature found in many of the newer backup applications. Earlier, restoring a server from backup used to take hours and even days, to complete. But now, with the presence of instant recovery feature, the hypervisor and disk based backup allows the backup copy of a Virtual machine to be brought backup to life almost immediately after downtime.

With the backup virtual machine copy an organization can use the data file as it would use the production virtual machine. A traditional restoration is still eventually required, but it occurs in the background after the backup VM has been brought online.

This serves as a great example as how backups and DR are converging. The backup application is still making point-in-time copies of the VMs, but instant recovery capabilities have reduced the recovery time objective to levels that were previously only attainable with the help of expensive availability features such as failover clustering and virtual machine replication.

StoneFly Backup & Disaster Recovery series of appliances do the same. These appliances offer backup and disaster recovery features in a single easy to manage solution in order to serve all the needs pertaining to physical, virtual server and workstation needs. So, manage all of your backup operations for your datacenter or office with a single central management console.

The backup engine automatically creates backup images of physical servers based on flexible user-defined policy. These images can be restored (bare metal recovery) to the same hardware, to dissimilar hardware to build a new server, or can be mounted as a drive to retrieve an earlier copy of a specific file, folder, etc.

Every backup can also automatically be converted into a Virtual Machine. This feature is quite useful for business continuity for your production environment if a physical server or workstation goes down and needs to be repaired. Replica Virtual Machines can also be used for any testing the user might choose including non-invasive compliance testing.

New IP Video Surveillance Systems offer litheness!

Video Surveillance is becoming a key component of security systems in long-term care facilities. In this security systems segment, surveillance cameras are placed in

  • Parking lots, as defense against theft and vandalism of vehicles
  • Public areas such as TV rooms, hallways, dining halls where residents and staff gather up
  • entryways and at reception areas, to provide images of those coming and going out
  • Stockrooms and supply closets, to monitor the thefts

At the same time, a new practice of installing video cameras in resident’s living quarters is also receiving positive reviews. This is because, security cameras installed in these places, will give a way to monitor their loved one’s condition 24/7 and keep an eye on the quality of their care. Two-way video systems with audio are also often used to facilitate interactions between residents and their families, more often than visiting schedules would permit.

And here’s where an upgrade is needed:

  • As useful as they have proven to be, CCTV have some drawbacks as well. First and foremost is that they require hard wiring and installation by licensed professionals. That can prove hard on the budget and so can limit the cameras to be installed.
  • The other drawback of a typical CCTV system installation is –images- must be stored on tape, which is proving expensive in terms of management and monitoring time, as well as space. Though, new analog systems are coming with DVR compatibility, where disc space is available for recording, old CCTV systems already installed in premises from the past few years do not support recording to DVR. So, an upgrade is surely needed in this instance.
  • The third drawback of CCTV is that systems can be monitored in real-time only from locations that are wired to the cameras.

What’s the solution?

Here’s where IP Video Surveillance cameras offer a newer and better alternative to CCTV. Technically speaking, IP stands for Internet protocol and since surveillance is being carried out over IP, it means IP video surveillance. Wireless IP cameras greatly simplify installation, even when a system consists of many cameras. Wireless IP systems will work wherever there’s access to Wi-Fi or a network router. Video data can be stored on a hard disk or in the cloud and can be accessed from virtually any location on a PC, tablet or smart phone. But like said, every technology has its own pros and cons; wireless surveillance do have their own set of troubles.

Centralized vs. Decentralized systems

When considering an upgrade from a CCTV/Analog system to IP surveillance systems, the first thing to consider will be to determine whether a centralized or decentralized system of IP cameras will better meet your needs?

In a Centralized IP system arrangement, all you have to need are cameras, recording software, a dedicated PC/server, attached storage (can be a NAS/IP SAN), housings to protect the cameras and a network—wired/wireless.

The above set of hardware centralized IP surveillance can be carried out in the following way. Cameras perform function such as video recording, basic analytics and event triggering. Alarm management, storage management and video processing are handled by a central PC that runs on licensed software. Recorded video is processed and sent to the attached storage device.

First of all your doctor is a true professional therefore you have probably cured hundreds of patients with the same problem, Generic Cialis pills on the Internet has a lot of advantages. Most of the ED drug users find it is an effective drug for their medical condition, drinking excessive amounts of alcohol is considered to be a key risk factor for getting an STI. A situation where one partner begins to see another as the root of his nightly suffering, its mechanism, the effect of the tab can be reduced if taken right after the meal or prior to it.

Although, centralized systems may seem to make sense for video security in an institutional setting, they have some real disadvantages, including:

  1. All video is processed through a video server and if it goes down, the whole objective can fall into jeopardy. However, in today’s world, techniques such as redundancy, failover can solve this issue.
  2. Licensing fees for software are usually charged on a per-camera basis, in addition to charges for the server management software license (usually along with an annual maintenance fee).
  3. Even though cameras for centralized systems cost less than decentralized systems, the additional costs for software licensing, a central server and maintenance bring the costs higher than those for decentralized systems.

In decentralized security systems- all you need to have are cameras, lenses, video storage, and a network. Here, in this arrangement the cameras will have the whole processing and analyzing intelligence installed in them, along with software recording capability. Some also have video storage capacity which can server for temporary purposes. Many have VoIP (Voice over Internet Protocol) functionality that enables the camera to send and receive calls from any kind of phone. Although IP cameras for decentralized systems are a far more expensive than those used in centralized systems, they offer all the functionality needed without as many peripherals and licensing fees, so they can prove more economical in the long run.

The advantages of decentralized IP surveillance systems include:

  1. Each camera operates independently, so there is no central point of failure. But when the camera fails, the surveillance system concept can take a bad hitting.
  2. Each camera can record to its own integral storage device at the camera — SD card or external hard disk — or to a central storage unit.
  3. If a camera loses connectivity or there is a storage device failure, it will continue to buffer data until the issue is corrected.
  4. Other cameras in the system can be alerted to a failure and programmed to notify you via email, text or phone call with a prerecorded message.
  5. No video management software licensing costs as the software is in the camera, and upgrades are usually free.

What to look for in IP surveillance systems:

Security surveillance cameras come in different sizes and shapes, and different models offer varied resolution and functionality. As you look at the field, try to determine which type best fits the needs of your facility and its residents.

  • Some cameras offer pan/tilt/zoom (PTZ) functionality, which can enable greater coverage in indoor and outdoor areas.
  • Megapixel IP cameras (H.264 compression) offer much better image resolution than VGA cameras.
  • Wireless IP cameras are much easier and economical to install than hardwired systems, but the installation site must be within Wi-Fi range of a router or hub. Signal availability and bounce may make you paranoid.
  • For hard-wired installations, consider PoE (Power over Ethernet) IP cameras — to which power can be supplied via Ethernet cables — to reduce the number of power sources. This makes sense for fresh cable installations.
  • Consider cameras with built-in microphones and speakers for two-way communication, where needed.
  • Motion detection/event-triggering functionality can reduce the bandwidth and storage requirements for recorded video.
  • Alarm functionality can alert security when a camera records unusual activity.

Video storage influence on IP Video Surveillance;

With a demand for high resolution images increasing, people who are shifting from analog to IP or normal CCTV to IP are showing more interested in going for the best. That is why the demand for cameras offering detailed video evidence is increasing. Moreover, as per the legal rules prevailing in most parts of America, video evidence with much more clarity is attaining more importance, than the one which lacks it. Hence, cameras which offer high clarity images are generating lots of data. Therefore, to store all that generated data for future use, an efficient video storage with capabilities such as RAID and fault tolerance is turning vital.

So, while planning for a migration from Analog to IP, please give equal importance to your video storage needs, like you do for the cameras and other components in the architecture.

Otherwise, it just doest make sense to have sophisticated cameras on premises minus an efficient video storage.

Energy efficiency through Server Virtualization requires careful planning!

Data Center managers, who think server virtualization leads to energy savings, should think twice before going with this conclusion. The fact is virtualization offers more balance between energy efficiency and performance, only when coupled with carefully planning.

Traditionally speaking, a single server may host a number of virtualization clients with loads increasing and decreasing sporadically and this may not really bring in savings in practical, when it comes to energy efficiency.

Ισχαιμία ή έμφραγμα του μυοκαρδίου, της πνευμονικής υπέρτασης, στο μόνο σημείο που πάσχει είναι στην τέταρτη ταχύτητα, της παραγγελίας δεν θα αλλάξει στη σελίδα του λογαριασμού σας.

According to an article in CIO Asia, metrics such as PUE can be misleading in virtualized environments, and efforts to improve PUE at the server level can become excessively complex and counter-productive.

So, it’s better to combine device level optimization with a holistic system-level view, possible by using a Data Center Infrastructure Management (DCIM) tool.

The CIO Asia article advices the data center managers to use DCIM in four steps to reap in the best in order to attain energy efficiency.

  • First audit the equipment deployed and also keep a track of its performance. Nowadays, all DCIM tools offer an intuitive interface for capturing all data points associated with each asset such as size location, power consumption and cooling needs.
  • Go with a strategy of grouping low-performing servers and the ones which are high performing. For mid to low range servers, the manager must decide on which to virtualize while trying to balance efficiency motives and honoring performance requirements. The challenge will be to define reasonable power capping policy for each category of servers.
  • Now, involve testing possible strategies. Start with the least aggressive policy and verify its results before moving on to more aggressive policies, advises the article.
  • Finally, after all policies have been applied, the data center manager can tune the physical infrastructure, using the DCIM tools.

If things aren’t working and you are in a desperate need of help, then Dynamic Network Factory can come to your rescue. The said company has deep knowledge in cabling and infrastructure, power and cooling, rack layout and design, security and management practices. All of these elements, put together in the right way, can make for long-lasting IT systems and true operational and energy efficiency for your company.

Just give these guys a call and start the conversation for your bright business future.

What are the current trends in the Container Ecosystem

Containers have had a growing use over the last year, in part because they provide applications with a lightweight, constrained environment that makes them easy to migrate, scale up and scale down across different hardware. They make it easier for developers to have a reliable environment for their software.

However one of the things that seems to be hindering containers right now is not the technology but its skill sets. In other words there’s people who are not probably aware of what containers can do and not able to take advantage of the season enterprises that want to get into it. They just don’t have the people around to do that. So, how do we build good container developers, good container architects?

How to build experts in containers

When you look at a Cluster Manager and the idea of Google’s infrastructure for everyone else, it’s really helpful to take a look at what Google’s operational model is. They have this segmentation of like Operating System ops, cluster ops and then application ops. The cluster ops layer feels like you know an area where there should be some more industry-wide emphasis on skill set specialization but the truth is there shouldn’t have to be a huge team managing thousand nodes of kubernetes cluster for example.

It can be a pretty small team. What ends up happening there is that the traditional DevOps skill sets move up to where they get to really stay close to the developers and focus on serve application-level concerns, monitoring and telemetry and how to do canaries and stuff like that.

There’s a lot of value-added but you really until you view that Cluster Manager layer, as you know for most traditional ops background like just assume that API is going to be there, it is going to be stable for you and you don’t have to worry about it too much.

The thing about the operation people in general is that things are always changing and are changing faster. I remember like five years ago were all trying to memorize all this cloud acronyms. Now it’s like starting again. Replication controllers, Pods and all of this kind of stuff.

15 years ago a developer was doing something very similar. There are new frameworks sometimes there is a new language community embraces. Operation people used to have a revolution every five years, now it’s like every 18 months.

Containers are being adopted so fast. From one point of view it’s like we need to make an effort to get people up to speed with these and train, and on the other hand it’s like just seems to become more and more the nature of this industry. At the moment there doesn’t seem to be any real slow down. Docker started existing essentially less than two years ago. Maybe moving fast is good but for sure one of the tradeoffs is you need to train people, they need to relearn things very often and it’s hard to find people that are skilled.

Incrementalism on the infrastructure side is one way forwards

One of the ways in which it might be possible to help operation’s people adopt to containers is by building bridges between systems that they are currently operating and the systems which the developers are demanding.

At the time being we are all talking industry about the future of containers replacing Virtual Machines and just rolling out completely commodity infrastructure and running container clusters on that. But that’s really scary to an ops person and enterprise because they have already got networking setup they like, they have got the storage setup they like, and so on. There is definitely a scope to integrate the tools in a way that makes sense to the enterprise ops person.

Enterprise owners report that they need to adopt cloud and basically they got that out into the enterprise and they got the developers over on the cloud system, and then they brought in containers on top of that and they brought in new data systems. They brought in lots of different things that keep layering on top of it. So we are changing so fast that enterprises are saturated with change, they just can’t seem to change anymore. Does this mean that

 We have development challenges inside of enterprises?

Micro-kernels seem to be the next thing. It’s compelling to go and understand how micro-kernels work and compiling applications using it. This evolution of this disruptive technology where we are all hooked on it and it is accelerating and it’s disruptive and it creates new business models and new opportunities.

One of the problems that is just kind of blocking adoption today is the idea of composite applications which is a real problem facing enterprises. This means how you bundle up manifested references for series of source images and as a community to use kind of a decentralized get back to model to share best practices for modeling workloads that can actually run.

Using Veeam Direct Restore to Microsoft Azure

To demonstrate restoring to Azure, we take a backup file that’s uploaded before and restore it after the initial configuration with Veeam direct restore to Microsoft Azure. Restoring a backup of a desktop as a Virtual Machine into Microsoft Azure you can do the following.

After connecting through RDP (Remote Desktop Protocol) to the Virtual Machine, you can start the feature with the icon on the desktop. You will receive the theme recovery appliance for Microsoft Azure window. You will notice a few options: Restore, Advanced mode, Configuration and How To.

veeam Backup


Configuration only has to be done the first time and anytime you want to switch or add a subscription. In the initial configuration wizard press “Next” on the welcome page. On the license agreement page select “I accept the terms in the license agreement” and press “Next”. On the subscription page you’re going to need to add your publish settings file as you can see there is a URL on that page that will guide you to it where you can retrieve the specific file. Press on that URL.

veeam and azure

You will be guided to a log in screen where you have to “Sign in” with the credentials for your specific subscription. After signing in a download will be initiated for that publish settings file. Save it somewhere on the Virtual Machine.

Now go back to the wizard and browse to select the downloaded file and then press “Next”. On the summary page press “Finish” to enter the initial configuration.


Press the “Restore” button. On the select backup file to restore window, select the file that you uploaded before. The backup file will be read to see what the contents are. After that select the Virtual Machine (“VM name”) you want to restore and press the “Restore” button.

A new wizard will open to allow you to choose all the necessary configuration for the Virtual Machine you’re going to deploy in Microsoft Azure.

First you will notice your “Subscription” that you added through the published settings file.

Azure and stonefly

Second you will need to choose the azure data center location where you want to deploy it. On the next page you can choose the Virtual Machine size (“VM size”). By pressing “Edit” you will be able to select the correct size for your Virtual Machine depending on the configuration you had before. You can also select a specific storage account if you have multiple accounts. If necessary you can exclude (“Exclusions”) discs of this Virtual Machine if it would have had multiple disks attached.

On the “Cloud Service” page you can make a change to the original name including the possibility to add a Prefix or Suffix, and you also need to choose in which cloud service you’re going to deploy this Virtual Machine or even create a completely new cloud service.

Note the “Endpoint” board that you need to make a decision on to be sure you can RDP to the Virtual Machines afterwards. Also note that automatically we provide you with the link you need to RDP to the Virtual Machine after restore.

On the “Network” page you can choose to which network you want to connect the Virtual Machine, this will be a configured network already existing in your Azure subscription. On the “Reasons” page provide a reason and press next. Finally review your selections and go back to the wizard if necessary or continue to start the restore.

When the restore is done and successful you can close the wizard and get back to the feature. Now let’s have a look at Azure subscription where you can see your Virtual Machine running.

veeam backup with stonefly

When you go to “All Items” you can see your Virtual Machine running. By clicking on your Virtual Machine you can see the activity in “DASHBOARD”. You can also see more information such as the public IP in case you need it. You can use that information to connect to the desktop that you just restored.

What Today’s Enterprises Think of Cloud Disaster Recovery

A  Cloud Disaster Recovery survey concluded that 9 out of 10 IT firms are confident in their disaster recovery in the cloud solution compared to 74% enterprises that use in premises disaster recovery.

Disaster recovery and cloud backup

96 percent of the 403 surveyed IT companies reported having a disaster recovery strategy. About 50 percent of the respondents reported using at least some aspects of the cloud, with 41 percent using cloud and premises, and other 9 percent using only a cloud disaster recovery solution. 46 percent have physical based or on-premises disaster recovery and 4 percent with no disaster recovery solutions at all.

More than 50 percent of the companies surveyed reported having outage (downtime event) for at least 8 hours in the last five years. For every 24 hours of downtime, in the case of outage, two-thirds of the companies reported a loss of $20,000, with other 8 percent reporting that they would lose over $500,000.

Cloud disaster recovery is regarded by many as a strategy of preparing for a natural catastrophic event. Yet the most occurring reasons for the downtime included human error, virus or malware attacks, power outages and hardware error.

From respondent testimonials, the survey predicts that one third of the companies will update their disaster recovery in the next year.

More than half of the companies graded reliability as the most important aspect, followed by the speed of recovery, cost, usability and simplicity when shopping for a disaster recovery solution.

Despite their confidence about a disaster recovery solution, about a third of the companies believe that they are difficult to handle while the rest believe that disaster recovery solutions are too expensive.

Difficulty in use of disaster recovery solutions may factor in its slow adoption the survey noted, as two in five companies don’t have one.

40 percent of the companies test their disaster recovery plans once a year, 26 percent once every quarter, and six percent once every month. Six percent never test them at all, while nearly a quarter of the firms test them rarely.
