1
Perform the following driver parameter settings for each model of ETERNUS DX/AF that is to be connec-
ted.
Driver parameter
lpfc_lun-queue-depth
lpfc_topology
lpfc_link-speed
*1: Recommended value = 1024 ¸ (number of Fibre Channel ports that are connected to a single CA
port) ¸ number of LUNs
(Round the result down)
• Use the value of "8" if the actual result is lower. Use the maximum value if the actual result ex-
ceeds the maximum value of the OS or the driver.
To achieve maximum system performance, this value can be changed according to the server
•
load and the peak operating times.
The number of simultaneous command executions per CA port for the ETERNUS DX/AF is limited
•
to 1024. This value is used by multiple servers that share the CA port. A maximum of 1024 com-
mands can be executed per CA port.
*2: Use the following "lpfc_link_speed" setting values.
