Summary  VFCache is easy and straightforward to setup, configure, manage and monitor in VShpere environment.  With the storage system optimized for SQL Server load, VFCache offloads read I/O from the storage while reducing the disk latency.  With storage optimized for SQL Server load, VFCache enables more SQL Server transactions processed and while reducing disk latency significantly.  VFCache can lower SQL Server response time for queries that have more reads and high response time  VFCache has minimal impact on system resources.  The initial warm-up time for VFCache to reach significant performance improvement varies for each environment. In our environment, it took about 1 hour.
