Back at EMC World in May 2011 EMC showed, and promised, a server side PCIe Flash based IO accelerator. In case you missed it, earlier this week EMC introduced VFCache, the promised deliverable from EMC World.
As always virtualgeek is all over the announcement, the background, technology and overall impact associated with VFCache.
VFCache moves the most frequently used data to the server-based PCIe card, putting the most active data closer to the application, thus reducing the need to traverse the storage network and array. Bottom line: Decreased response time = Increased Performance. That’s all cool, what does it mean to my Microsoft Apps?
A key point of the announcement is the extensive “Real World Application Testing” already completed by EMC engineering. Specifically, the work done with Microsoft SQL, resulting in 87% better response with VFCache enabled. Even more impressive is the small print.
“Solutions architecture consists of Microsoft SQL Server 2008 R2, Cisco UCS, and EMC VNX5300. Testing employed a standard TPC-C like OLTP workload with a 750GB database and a 90/10% read/write mix. VFCache enabled on all data LUNs, but not on log LUNS. No tuning of SQL database.”
That’s 87% better performance with no SQL tuning using SQL 2008 R2. As you have heard here and on Inside the Partnership, EMC is a diamond Sponsor of the SQL2012 launch. If we are seeing this type of improvement with SQL2008, what could you expect from a SQL2012 deployment? Stay Tuned….
In the meantime, here is the full whitepaper “EMC VFCache Accelerated Microsoft SQL Server”, detailing the SQL testing. As always, you will find all of the latest information on the Everything Microsoft at EMC Community site.
