Integrating solid state storage as a VMware cache isn’t a trivial task. In fact, it’s become the core challenge for some of the best minds in storage, and few real answers have yet emerged. This will be a primary area of focus for me and others who watch and comment on virtualization and enterprise storage!
EMC VFCache (aka “Project Lightning”) Is One Small Step, But an Important One
EMC VFCache (nÃ©e Project Lightning) is a fairly simple offering: A server-based PCIe flash card that acts as a read cache with no integration with storage arrays or hypervisors. But EMC’s entrance into the host-based flash storage market is a powerful demonstration of the wave of disruption caused by flash-based storage and high-performance computing.
