  2. Content • Architecture Design • Configure VFCache for a Virtual Machine • Enable VFCache • Performance Impact of VFCache on a system with storage optimized for the SQL workload • Performance Impact of VFCache on a system with storage bottleneck • Q&A EMC Solutions Group Strategic Solutions Engineering

  3. Architecture Design

  4. AlwaysOn Replication VFCache

  5. Storage Design for SQL Server

  6. Configure VFCache for VM

  7. Test Results:

  8. Test Results— Enabling VFCache 1 VFCache LUN: 278 GB 16 data LUN: 1.8 TB Time to reach the steady state: 1 hour

  9. Same workload before/after

  10. The CPU usage was very similar before and after VFCache was enabled, indicating that the VFCache had minimal impact on the CPU usage.

  11. Same workload before/after

  12. The CPU usage was increased about three times after VFCache was enabled. Because the SQL Server transaction increased, the increase of CPU usage was expected.

  13. 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.
