Dell released a new virtualized storage accelerator appliance called Fluid Cache for SAN on Tuesday, designed to help customers keep data-intensive applications working quickly under load. The announcement, which was made at Dell's Enterprise Forum in Germany, outlines a virtual appliance meant to eliminate some of the performance problems associated with using SANs for responsive, customer-facing applications. Fluid Cache uses the Flash memory inside a server to act as an I/O cache for SAN systems, boosting throughput.
