max_fcp_reqs defines the maximum number of concurrent
Fiber-Channel FCP requests that are to be allowed on any FCP adapter
installed in the machine.

Specify integer value or use integer formula expression. If you set
max_fcp_reqs to a value that is too low for the adapter to
function properly, the system will set the value to the minimum
required. See Specifying
Parameter Values.
max_fcp_reqs specifies the maximum number of concurrent FCP
requests that are allowed on an FCP adapter. The default value
specified when the system is shipped is 512 requests. To raise or lower
the limit, specify the desired value for this parameter. The optimal
limit on concurrent requests depends on several different factors such
as configuration, device characteristics, I/O load, host memory, and
other values that FCP software cannot easily determine.
The system allocates memory for use by Tachyon FCP adapters based on the
comination of values specified for num_tachyon_adapters and
max_fcp_reqs.
