MSA1500 poor performance

[Brian Richter]

My system performance is only about 80MBs, anyone have any suggestions for issues I can look into to gain a better performance?

Thanks

[James Muell]

pls list the host specs incl multipathing, HBA model, drvr & fw.
list the MSA config incl fw rev; # arrays # of luns; Raid set type; # disks in each array # of logicals on each array.

Below is the capture from the controller settings, I only have a single switch and MSA controller connected right now, waiting to figure this problem out before I install the second and multipath software.

There are a lot of variables of course(Raid level, Read, Write or R/W, Random or Sequential, Controller Cache your set for 10% Read /90% Write ) but from your config info all your arrays/logicals are on a single Ultra3 (160 MB/s)SCSI Bus except array F/Logical 6. For better performance on the MSA1500 side, I would have recommended creating the arrays across all 4 SCSI channels. As a test, check the performance on Logical 6 with Array G/Logical 7. They are similiar size and both Raid 1. If 6 has better performance then it is probobly cause it is using 2 SCSI channels vs only 1 on logical 7 and would be even better with all 4 Channels. I would also recommend upgrading the MSA FW to the latest 5.10 from your 4.98
