Hi vmroyale,
thanks for your reply on my question. the decision was made by a former administrator who left the company, the choice was never really optional. now admins have this discussions because i didn't want to upgrade the snapdrive all the time if we upgrade the ONTAP of netapp. What i am trying to meet is to provide fileservers and SQL servers (non cluster) to have:
fileserver:
OS - NFS with SAS disks
data - ISCSI with SATA disks other aggr.
SQL servers:
OS - NFS with SAS disks
database - ISCSI with sas disk other aggr.
log ISCSI with sas disk other aggr.
Our Admin team for Vmware is now discussing it, to use SNapdrive or to create a datastore to the netapp with iscsi and than simple add Hardware disk's to the VM or create RDM on the VM. some of use prefer Snapdrive and some Datastore and some RDM. for a fileserver / SQL server what is better to use?
