it's not supported yet, so you can have failover on Open-E + single Windows / Hyper-V or you can have single Open-E + Windows / Hyper-V cluster.

From release notes of the latest update ([2011-03-01] Open-E DSS V6 ver. 6.00 up65 build 5217) :

"When using DSS V6 in windows 2008 cluster environment a failover event on DSS V6 will break i/o operation performed on the DSS V6 iSCSI target e.g. copying of files"

I think that Open-E is working on this problem.

Real HA shoud have (at lest):

- 2 x Open-E in failove
- 2 x Windows in cluster
- 2 x switch
- 2 x administrator (if one will take day off :-) )
