Issue Description

Explain the parameters of SAN storage performance and their relationship

Alarm Information

None

Handling Process

1)      Throughput(MB/S) = IOPS*average IO size
In order to get a better IOPS result, you can set a smaller IO package
In order to get a better Throughput result, you can set a bigger IO package
 
2)      IOPS = 1000 / average Response time
The faster response time of a storage has, the higher IOPS is

Root Cause

IOPS, throughput and Response time are the core parameters of SAN storage and reflect the IO performance status directly

Suggestions
