CLI> set subsystem-parameters -load-balance enable -tp-alloc-mode tpp-balancing
Optional. This parameter specifies whether to enable or disable the Turbo mode. The Turbo
mode is a function that makes processors work at a higher frequency than the rated frequency
to improve performance. This function is also called Intel® Turbo Boost Technology. The default
value is "disable".
This parameter cannot be specified for the ETERNUS DX100 S3/DX200 S3 or the ETERNUS
DX200F.
enable The Turbo mode is enabled.
disable The Turbo mode is disabled.
Optional. This parameter specifies the number of process commands that are issued during
Writeback (writes data back to the drive). The bigger the Writeback Limit Count is, the more
the resources that are used for the write process becomes. Cache hits for the write process also
become more likely to occur. The smaller the Writeback Limit Count is, the less the resources
that are used for the write process becomes. However, it is more likely to cause a write cache
miss.
The default value is 512.
128 Sets the Writeback Limit Count to 128.
256 Sets the Writeback Limit Count to 256.
512 Sets the Writeback Limit Count to 512.
1024 Sets the Writeback Limit Count to 1024.
2048 Sets the Writeback Limit Count to 2048.
3072 Sets the Writeback Limit Count to 3072. (ETERNUS DX500 S3/DX600 S3 only)
