Single Points of Failure
The Model 30/FC Disk Array virtually does not have single points of
(SPOF)
failure. However, care should be taken to bind LUNs as described in the
Model 30/FC Disk Array manual. The manual addresses topics such as;
spreading LUNs equally across internal buses and using RAID modes. In
a cluster configuration, single points of failure arise due to the method
used to connect the disk array to the server. These single points of failure
are as follows:
• Due to Windows NT inability to allow for dual data paths, a total
fibre-channel hub failure (removal of power from the hub,
catastrophic failure of multiple hub ports) will result in the loss of the
cluster. It is possible to power the hub using an UPS to remove part
of the issue, however an unforeseen total hub failure would still be a
single point of failure. Current data on the fibre channel hub
indicates that risk in this area is minimal.
• If the data connection between the hub and Model 30/FC Disk Array
is broken the cluster will go down. The fibre channel cables are
generally known to be robust with an insignificant possibility of
failure.
• A failure in the storage processor of the Model 30/FC Disk Array
will result in a loss of the cluster. The possibility of the storage
processor failing is small. Current configurations do not allow for
failover to another storage processor in the Windows NT
environment.
