John Savill, author on WindowsITPro.com, posted a great Q&A on 11/12/09. The question: “Which is better: a 10Gb Ethernet connection to IP storage or an 8Gb Fibre Channel (FC) connected to a SAN?”
John makes a great point that even though FC might outperform IP for large block I/O, IP can still take the lead in virtualization loads that consist of lots of small block, random I/O. Another good point he makes is IP requires less complex hardware than FC, making it feasible for more and more organizations to make the move to external storage.
We have been testing our Voyager on 10GbE vs. 8G FC array in our labs, stay tuned for updates on the results.
