Here’s some great advice from the Enterprise Storage Forum on cutting storage costs.
- Try flash or solid state disk. Amazingly enough, with the speedy performance on SSD, it is probably cheaper than adding more memory to your heavy duty database clusters. I’d recommend trying an ISC with SSD, to save money and still have speedy performance.
- Use tiers. You don’t need to keep all of your data on high priced disks. Mix it up. Some data on SAS, some on SSD and some on SATA.
- Use SATA as much as possible. See the tip above. I bet 65% of your data can reside on slower disks. You’ll get more capacity for the money, and have more space to consolidate with.
- Shop around for deals. You shop around for your computers, gadgets and cell phone service. Do the same for your storage. Most vendors sell through the channel, and one of these channels will have a better deal for the same part number. Ask your vendor if they have a trade-in program as well. You might as well get credit for your old, out-of-date systems.
- Consolidate, consolidate, consolidate. It doesn’t make sense to have inidividual arrays for every application server, since as you increase servers, you’ll need twice the hardware. Consolidate over the network with NAS, iSCSI or fibre channel. Less harware = less ongoing maintenence costs.
- Try Windows Single Instance Storage feature. This is a way to dedupe, and make sure you only retain a single copy of each file. (Ahem email attachments to your team.)
- Lease equipment. Leasing is a great way to reduce capital expenditures and keep you from dealing with outdated equipment all the time. Try it. We all know how Moore’s law works: next year your system will be outdated.
- Go open-source. Have you used Amanda? It is a great open-source backup application. Are there other ways for you to leverage opensource? Look around. You might be able to get away with FreeNAS for your developers. No need to spend extra resources on test systems when you don’t need to.
