For operations, one can also breakdown by offset, latency, size and SCSI command, allowing
one to understand not just the what but the how and why of FC operations.
The appliance has been designed to utilize a global set of resources to service LUNs on each
head. It is therefore not generally necessary to restrict queue depths on clients as the FC ports in
the appliance can handle a large number of concurrent requests. Even so, there exists the remote
possibility that these queues can be overrun, resulting in SCSI transport errors. Such queue
overruns are often associated with one or more of the following:
Overloaded ports on the front end - too many hosts associated with one FC port and/or too
■
many LUNs accessed through one FC port
