Figure38PortsinHighSpeedModeorInitiator/ExternalMIXmode

If High Speed mode is applied to the four ports in a

port block, only two of the ports can be used for

connecting the host. When hosts issue I/Os to por

ts, the I/Os will be processed by processors on

channel adapters. I/Os to each port will be proce

ssed by only one processor in Standard mode, but

by two processors in High Speed mode. Therefore, ports in High Speed mode can process I/Os faster

than ports in Standard mode. By balancing the workloads on the processors, a greater improvement

can be expected with the system performance.

You cannot change standard mode to high-speed

modeorviceversa whileyou are onlinetothe hosts.

You will need to reboot the hosts after changin

gthe mode.

To change the conﬁguration of a port that is bei

ng used, you must perform a backup operation before

changing the port conﬁ guration.
