Redundant iSCSI in Hyper-V Environment

Q: I am looking to setup a Hyper-V cluster that uses iSCSI for it's central storage. I am worried that the iSCSI storage device is potentially a single point of failure in the solution. Is it possible to attach a second iSCSI device to the environment to overcome this and how would it be done?

A: Is your interest in having two iSCSI SANs, or simply building redundant paths.  For example, an iSCSI SAN can be configured with redundant network paths (two switches), multiple NICs, and Multi-path IO on the server side.  Most iSCSI SANs also support data replication to another SAN.   Alternatively, you could use a tool like DPM to backup the VMs so you could recover them to an alternate environment.
