Hi sorry for bad eng and picture :).
Can such a decision?
3 servers openfiler give their drives 2 - 1 tb ISCSI server to
OpenSolaris
On OpenSolaris assembled a RAID-Z with double parity.
Server OpenSolaris provides NFS access to this array, and duplicated
by means of Open HA CLuster
Yes, you can.
With three servers you want to to provide resiliency against the loss
of any one server.
I guess these are mirrors in each server?
If so, you will get better performance and more useable capacity by
exporting each drive individually over iSCSI and setting the 6 drives
as a raidz2 or even raidz3 which will give 3-4 drives of capacity,
raidz3 will provide resiliency of a drive failure during a server
failure.
