Hello

Using drbd  + nfs + heartbeat on  prod system with esxi 4 free
without any problems.

I have exprienced with iscsi target ietd but iscsi write performance of
ietd  was poor (20MB/sec over Gbit network direct crosscable) and even
hearbeat integration has no problem i have to do iscsi target scan on
the esxi host for datastore recognation after heartbeat transition

I have no problem with nfs but my first drbd+nfs with ext3 FS servers
were latest centos 5 i386 and suffered in term of performance and now
i am using debian stable with xfs FS, I even not know which was
causing problem (nfs or kernel or FS).

Good luck.
