The architecture is pretty straight forward. A PCIe extension-like card is installed in each of the connecting servers. The vSTOR has multiple PCIe SSD cards installed in it as well as receiving ports for the PCIe connections. Today, because neither of the PCIe SSD providers support SRIOV (single root I/O virtualization), sharing is only granular down to a server per PCIe SSD card. This allows you to virtually “move” cards between servers as pick loads dictate. NextIO is working with their vendors to get SRIOV on the SSD boards, at that point you will be able to sub-divide the SSD between multiple connecting servers further amortizing the SSD investment.

Storage Switzerland’s Take

This type of solution, especially when SRIOV capable, is ideal. As we have pointed out in our Visual SSD Readiness Guide most environments don’t need TBs of SSD capacity for each server. A fraction of SSD can make a huge difference in performance. The ability to sub-allocate one of the most cost effective ways to deliver SSD (the PCIe card) and do so while maintaining one of the best I/O paths becomes a very intriguing option for SSD.
