Target Port Limits and Specifications
To avoid overwhelming a target port and ensure continuous I/O operations, observe the following
limitations on a target port:
• For information on host port per target port and the maximum total host ports per array, see
the HP 3PAR Feature Availability Matrix documentation on the HP Single Point of Connectivity
Knowledge (HP SPOCK) website:
HP SPOCK
• I/O queue depth on each HP 3PAR StoreServ Storage HBA model, as follows:
QLogic 1G: 512◦
◦ QLogic 10G: 2048 (HP 3PAR StoreServ 10000 and HP 3PAR StoreServ 7000 systems
only)
• I/O queues are shared among the connected host HBA ports on a first-come, first-served basis.
• When all queues are in use and a host HBA port tries to initiate I/O, it receives a target
queue full response from the HP 3PAR StoreServ Storage port. This condition can result
in erratic I/O performance on each host. If this condition occurs, each host should be throttled
so that it cannot overrun the HP 3PAR StoreServ Storage port's queues when all hosts are
delivering their maximum number of I/O requests.
