HYPER-V Active Active or ACTIVE-Passive?

I have two identical hyper-V servers. I am setting up a cluster with two SAN servers. My SAN software (open-e) allows for the SAN boxes to be both Active - Active meaning they are both load balancing and both in a live state vs Active-Pasive where one box is live with all the activity while the passive box just replicates and waits for a failover.

Can this be done with HYPER-V? Instead of having one of the clustered servers sitting their doing nothing. Can I have it so both boxes are active and as long as there is enough memory and CPU on both boxes - if there is a failure - the VMS can just failover to the box that is still live.

I have 2008 serve R2 datacenter on both servers.

In the context of hyper-v, all nodes are always active. They may not be running any VMs, but they are still active and will matter in the event of determine node failures in a quorum.

Hyper-V 2012 can support HA, so if a Host Fails, the VM will be restart on another host.

To clarify: I have 4 vms. One server can hold all 4. However, can I put two VMs on one host and two VMs on the other and if either host fails the two VMs will fail over to the other host. Making one host with 4VMs?

Is that possible or do I have to have all 4 on one host that failover to the other host if one host dies?

As I said, in Hyper-V clusters, all nodes are active. You can put VMs on any node (so yes, you can go 2 and 2) and configure the individual VM failover settings to failover to another node or not failover at all as you see fit.
