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.

What do you want to failover Virtual Machines, Printers, Storage?

Do you have two servers and a SAN?

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?
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

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.
