Is it possible to configure a SCSI cluster using two Alphastation 255's
using the internal SCSI controller and the Cluster Client Software that
come with NAS150?
According to the Cluster SPD everything is supported except the client
cannot vote in the cluster or act as an MSCP server.
Would the inability to Vote prevent the cluster from forming a quorum
and booting.
Also what would happen should one Alphastation fail.
Thanks
Barry

You need at least one full VMScluster license.
: Would the inability to Vote prevent the cluster from forming a quorum
: and booting.
I'm not sure if there are currently any technical prohibitions
that would prevent this from a technical standpoint, but there
certainly _are_ licensing prohibitions -- the customer would be
in violation of the software license agreement. And technical
prohibitions that might limit or might prevent this configuration
may be added at any time in the future.
: Also what would happen should one Alphastation fail.
If there are sufficient votes on the remaining node (either
directly, or via a quorum disk), processing would continue.
If not, the VMScluster would initiate a "user data integrity
interlock" -- better known as a "quorum hang".
