• Use the value of "8" if the actual result is lower.
• To achieve maximum system performance, these values 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. These values are used by multiple servers that share the CA port. A maximum of 1024
commands can be executed per CA port.
The parameter to be specified is determined by the CPU which is installed in the server to be connected.

Add this parameter if it does not exist.
Example:
set ssd:ssd_max_throttle = 20
For x86
