Finally, in the something-we-mere-mortals-can-understand department, comes this piece on virtual SANs from Scalent Systems that I found on Infostor. Of course, Scalent is plugging its new Virtual Operating Environment (VOE), and it's not for me to say whether this solution is any better than anyone else's. But it does make a plain case for the implementation of virtual SANs as a way to lower costs, improve network load management, and simply relieve yourself of the hassle of SAN reconfiguration.
It seems that Virtual Iron sees the benefits of virtual SANs as it seeks to keep the pressure on its more well-known competitor, VMware. The company recently inked two important deals that could have an impact on your data center soon. One was with EqualLogic, in which VI has certified the PS Series iSCSI SAN array for its virtualization and management stack. The other has VI taking part in the Hewlett-Packard Bladesystem Solution Builder Program, which should start to produce VI-loaded ProLiant abd Bladesystem c-Class servers relatively soon.
Another potential solution comes from Emulex, which has released the Model 765 Intelligent Services Platform, providing hardware acceleration throgh a split-path architecture designed to foster SAN virtualization, among other benefits.
At the moment, most virtualization efforts are focused on the operating system. But once you've nailed that down, the next logical step would be your storage environment.
