SQL 2005 High CPU on Server 2008 VM
Posted on 2012-12-28
I have the current setup:
Dell R420 w/ PERC H310 controller
32 gb RAM
1.8tb local storage, RAID 10 (4x7.2K SAS drives)
VMWare Essentials 5
There are only two VMs on this server. Both are Server 2008 R2.
I am having a problem with one of the VMs. It is running SQL 2005 SP4. Whenever I launch the application (Microsoft Dynamics RMS 2.0) that accesses the database in SQL 2005, CPU usage hits 100% and the application often freezes and times out. In the times that the app does not time out, I can access the data through the application without any problems (with the exception of running reports, which are slow and tax the CPU).
The VM is configured for 16gb RAM and 2 socket x 2 core processors (4 total processors).
The machine I migrated this database from is six years old, with 4 gigs of RAM, RAID 1 (mirrored drives) and a single processor. Performance is great :)
Can someone point out where I have a configuration problem/issue? I have ran esxtop and DAVG/rd/wr seldom exceed 15ms (same with GAVG/rd/wr). I initially thought it was a performance issue due to the 7.2K drives, but that doesn't seem to be the problem.
Any advice would be greatly appreciated. Apologies if I don't respond until Monday, it's almost the weekend (thankfully)
