SAN or DAS Hyper V Performance
Posted on 2015-01-28
We currently have 2 Hyper-v hosts (IBM X series) with local attached storage. In total we have 14 VM's.
Each VM acts as a RDP Host and provides access to an ERP Solution based on SQL & MS Access.
We had some issues lately with local drives and we are looking into replacing our DAS with a entry level SAN cfr IBM v3700. (We like to do live migration , replication....)
The SAN should host all 14VM's . The 2 hosts don't have an SAS HBA to connect with the SAN. So the only option would be to use the 1GB iScsi port. Would this be fast enough to provide access to all of our VM's ? Or should we consider to buy an IBM 6Gb SAS HBA for each host ?
For the replication part we want to use Veeam backup & replication on a 3rd host seperate host. The backup repository should also be on the SAN if possible.
Can you provide use some advice what would be the best scenario ?
