This document discusses how Fusion-io products can improve virtual desktop infrastructure (VDI) and virtual SAN (VSAN) performance. It provides an overview of Fusion-io's flash storage acceleration technology and customer base. It then outlines how Fusion-io's ioMemory products can be used to greatly increase VDI density and improve VSAN performance and scalability by integrating flash as a caching tier compared to traditional spinning disk or SSD-based storage architectures. Sample configurations and cost comparisons are provided that demonstrate significant capital expenditure and operational savings when using ioMemory for VDI and VSAN deployments.
