HP P10000 Implementation Guide

After connecting each host server HBA port and HP 3PAR Storage System port to the fabric(s),
verify the switch and zone configurations using the InForm CLI showhost command, to ensure
that each initiator is zoned with the correct target.
In the following explanations an initiator port (initiator for short) refers to a host server HBA port
and a target port (target for short) refers to an HP 3PAR Storage System HBA port.
Configuration Guidelines for Fabric Vendors
Use the following fabric vendor guidelines before configuring ports on fabric(s) to which the
HP 3PAR Storage System connects.
• Brocade switch ports that connect to a host server HBA port or to an HP 3PAR Storage System
port should be set to their default mode. On Brocade 3xxx switches running Brocade firmware
3.0.2 or later, verify that each switch port is in the correct mode using the Brocade telnet
interface and the portcfgshow command as follows:
brocade2_1:admin> portcfgshow
Ports 0 1 2 3 4 5 6 7

where AN:AutoNegotiate, ..:OFF, ??:INVALID.
• McData switch or director ports should be in their default modes as type GX-Port with a speed
setting of Negotiate.
• Cisco switch ports that connect to HP 3PAR Storage System ports or host HBA ports should
be set to AdminMode = FXand AdminSpeed = auto port, with the speed set to auto negotiate.
• QLogic switch ports should be set to port type GL-port and port speed auto-detect.
• QLogic switch ports that connect to the HP 3PAR Storage System should be set to I/O Stream
Guard disable or auto, but never enable.
Target Port Limits and Specifications
To avoid overwhelming a target port and ensure continuous I/O operations, refer to the following
limitations on a target port:
• Maximum of 64 host server ports per HP 3PAR Storage System port, with a maximum total of
1,024 host server ports per HP 3PAR Storage System.
• I/O queue depth on each InServ Storage Server HBA model as follows:
QLogic 2G: 497◦
◦ LSI 2G: 510
◦ Emulex 4G: 959
◦ HP 3PAR HBA 4G: 1638
◦ HP 3PAR HBA 8G: 3276
• The I/O queues are shared among the connected host server 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 Storage System port. This condition can result in erratic I/O
performance on each host server. If this condition occurs, each host server should be throttled
