Hello All,
My current project is running on Oracle Sun Fire x2-8 server and they have brought me in to build a HA solution for SQL Server 2012 for one application that cannot be ported to Oracle. Not being familiar with OVM and thinking it was similar to VMware, I requested 2 VMs built as a MS Windows Cluster so I can install SS2K12 as a 2-node cluster and install the app. The infrastructure team is pushing back, saying:

' It is not possible to establish a heartbeat connection between the two virtual servers in OVM as we have it configured now. If you need that functionality, I can have the team do a change request to set up that functionality but it sounded like it would take a little bit of effort. Otherwise, if you are just shooting for HA capabilities then we can set up that directly through OVS and flag the two virtual servers as HA.'

I would think that if they build the servers like this, then Clustered SQL Server is out the window. Does anyone have any experience with this architecture?

I am not familiarized with OVM either, but pretty much is like VMware, but made by Oracle. Of course, hardware and system requirements are different.

But the heart beat is just a simple NIC on the VM that uses a private IP. Why they can't setup that on OVM? Do they really setup the MS Cluster for you or maybe the got confused and setup two independent machines? Ask that.

Again, I am not familiarized with OVM but it should support several NICs on the guest machine.

The only tricky part would be recreating the SAN. That's relatively easy on VMware, but not sure if that may be a problem with OVM. The MS Cluster needs a share disk, and without that, it can't be completed.

If you are installing a SQL Server Cluster on a Windows Cluster thern you need a shared disk.

If this cannot be provided by the storage infrastructure you can use a third server to run ISCSI target software to provide the shareable disk but by doing this you have introduced a single point of failure, which makes clustering SQL Server a bit pointless.

Have you considered using SQL 2012 Always On (ie database mirroring) to achieve your HA objective. This also neds a Windows cluster, but does not need any shared disk. You may need a third Windows instance to act as a Witness for the cluster, but this can be a low-spec instance. With Always On you get the high availability you are after, plus you can use the target machine for read-only queries (you need to license the passive machine to do this).

Are both VMs on the same host?

All they should need to do is to create a new network on the network tab and enable it for virtual machine traffic only. Create a vnic on this network for each node and theres your cluster heartbeat network.
