3.4.5 SSH

The number of SSH connections for a single instance of the InForm OS is limited to sixteen at
any given time. Each instance of 3PAR GeoCluster for Windows resource will use one SSH
connection (as will administrative SSH connections.). This must be taken into consideration
when designing a cluster relying on 3PAR GeoCluster for Windows.
CAUTION: TCP/IP port 22 should be enabled on network firewalls between
MSCS nodes and InServs.

Disruptions of the SSH communication between 3PAR GeoCluster for Windows and InServ
storage arrays, or of the Remote Copy link between InServ Storage Arrays, do not affect the
3PAR GeoCluster for Windows resource. This kind of disruption will not cause any resource
to be brought offline or failover to take place. The same applies to InServ node reboots and,
by extension, InServ node firmware upgrades. These modifications will not affect the cluster
function and should not cause any resource to be brought offline or a failover to take place.
