    Perry,

    Thanks for replying.

    The server uses VMWare and the sysadmin wrote the following to me:

    'All of these drives are situated on the same set volume on the NetApp'.

    He also wrote that though the files are separated on the logical level but may give more benefits on physical level. If the files are on different logical drives only then it just gives better manageability and nothing else.

    Please suggest.

    Thanks

    Chandan

    Can your NetApp storage admin give you an additional LUN or two on a seperate volume on the NetApp? Is he/she seeing latency on the NetApp? Where is your tempdb? It might be worthwhile to move that to a seperate LUN as well.

    As for the RAID, depending on the NetApp, it might all be a certain type, maybe RAID 6 or some kind of proprietary RAID. You could also ask your NetApp admin about that as well. Se if he/she has volumes with different RAID types or if they're all the same.

    On a side note, when are you seeing latency spikes? What are the numbers? Spikes are normal at times. Depending on what other VMs you have running on that same physical server, it could be an HBA bottleneck. That is why you need to ask your NetApp person if they're seeing latency. They should have monitoring tools to check the volume or LUN.
