Click this option to access the window where you set the Pool’s throttle. 
You can define a throttle for IOPS, bandwidth, or both as shown in Figure 6-13 on page 200: 
/SM590000IOPS limit indicates the limit of configured IOPS (for both reads and writes combined). 
/SM590000Bandwidth limit indicates the bandwidth, in megabytes per second (MBps) limit. You can 
also specify limit in GBps or TBps.
