I know there are a few threads on this but I can't seem to find a definitive answer in terms of best disk setup.
My current hardware is 2 VMHosts with 3 Shared 1GB iSCSI Equallogic SAN Arrays all configured in a RAID 50 setup with 48 disks each.
All VM's are hosted on one SAN Array with 4x(2TB) VMFS volumes in a RAID 50.
Most recommend VMFS as the disk/storage setup.
See http://communities.vmware.com/thread/288588
If I were to follow traditional best practice, would I need to create 2 VMDK's for Database and Logs?
If the VMDK resides with the VM folder anway (in vSphere) then it would be using the same spindles anyway?
At the moment I just created the one disk and installed both Database and Logs to D:\Databases D:\Logs.
We only have ~25 users here and it will only initially be used for SCCM for now but may be used for hosting more databases in future.
The other 2 SANS are used primarily for SMB Shares but do have some free space for VMFS Volumes.
I am unsure what numbers are ideal for IOPS as I'm no SQL expert.
Here are some disk testresults using parkdale with 1gb filesize in 64kbyte blocksize
Disk write is averaging 60MB/sec
RandomQD32 7.7MB/sec, 1972 IOPS, 0.51ms
Read is 58MB/sec
RandomQ32 538 kB/sec, 134 IOPS, 7.43ms
What is the recommended setup for SQL server on iSCSI SAN infrastucture?
