1.3 Setting Up the Server
7
Add the results in the "WWN instance management table for the server".
Example:
Physical slot
name
PCIE 0
PCIE 1
This completes the "WWN instance management table for the server".
1.3.1.2 Setting the Configuration File (/etc/system)
1
Edit the configuration file.
Edit the configuration file (/etc/system) and specify the command queue depth.
The appropriate command queue depth is determined by the ETERNUS DX/AF model, as follows:
Model
ETERNUS DX/AF
*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.
• 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.
For the ETERNUS DX/AF
•
The parameter to be specified for the command queue depth is determined by the CPU which is in-
stalled in the server to be connected.
For SPARC
-
Specify the command queue depth for the "ssd_max_throttle" parameter.
Add this parameter if it does not exist.
Example:
set ssd:ssd_max_throttle = 20
