Setting Up the Fibre Channel Cards
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.
