Setting

 

Description

 

 

 

 

 

Disable

 

Controller will allow drives to optimize for throughput, resulting in higher maximum

 

 

 

latencies for some workloads.

 

High

 

Controller will attempt to compel disks to complete operations in a timely manner, but

 

 

 

still allow for some drive optimization. Doing so will lower the effective throughput for

 

 

 

some workloads.

 

 

 

 

 

Low

 

Controller will compel a disk to complete operations at an earlier time compared to the

 

 

 

high setting, resulting in lower maximum latencies, but lower throughput.

 

 

 

 

IMPORTANT: Setting a higher level of FLS can result in a loss of throughput for some request

 

patterns.

 

 

 

 

To enable FLS:1.Open HP SSA. For more information, see "Using the HP SSA GUI (on page 17)."
