Creating a Win2k12 R2 SAN with HA failover
Hey guys,
So I have the hardware I require for a nice SAN, including a 10Gbps switch and NICs. The OS I installed on the servers are Windows Server 2012 R2 Standard.
I know I can create an iSCSI target on the system, and access it from something like Xen Server, VMware, etc...
What I am confused about is setting two of these systems up such that if one fails, the other one automatically takes over. Ideally, they would be mirrored, like a Raid 1 for drives, so there would be no loss of data.
What do you guys recommend?
Yes, I am also willing to switch OSes, although I am keeping with MS right now as this is what the client wants.

I'd like it to be active-active HA, for storing VMhosts.
I have a few servers (running hypervisors like Xen Server), and two identical Storage servers that I want to use as mirrored SANs.

So you want this to store Virtual Machines? e.g. storage
or Hosting for Virtual Machines? e.g. a Hypervisor ?
e.g. why don't you just connect Xen Server directly to SAN?

I won't be installing a hypervisor on these two systems, I have existing ones that will connect to it like you mentioned.
My concern is, how do I go about making the two SANs mirrored? Similar function to a RAID 1 storage array, except this is to mirror two entire SANs. At the very least, the iSCSI targets I create on them.
Why do I concern myself with this? Well, in case one SAN Fails, I need the other to keep doing the work so there is no down time.

Thank you for the info. I'll look more into the software specified, and an external SAS.
Do you have two servers and a SAN?
