To increase performance, the controller can cluster sequential write commands
together to create a larger write command. This results in less commands being
sent to the hard drives. Additionally, if sufficient data is clustered by the
controller, it can perform a a full stripe write for RAID5/50 arrays. This
significantly improves performance. In cases where the host does not send a
sufficient number of outstanding writes, writeback cache can be used to delay
the write to disk, increasing the likelihood of clustering more data.
The View Command Clustering Statistics screen is accessed by going to the
Statistics Types menu (see
