MSA1000 add more controllers

[Amer Khan]

James, so you are suggesting to replace the original controllers in the MSA1000 to E200, which will give higher transfer rates from 160mb/sec to 300mb/sec and that would help with performance. Just wanted to get the facts straight before I talk to my manager.

Thanks, Amer.

The E200 is a PCI-backplane controller which talks to SAS + SATA disk drives (while the MSA1000 design uses parallel SCSI):

It does not fit into the MSA1000 and there is no replacement for the MSA1000 controller module.
There is not much difference between the MSA1500cs and the MSA1000 as both use the MSA1000 controller module.

If you want to process more I/O, you can "scale out" by buying a second or third MSA1000/1500cs.

James,

I have 1 FC switch, which is seperate to the disk array. I'm trying to measure the performance of the MSA, not the fibre network. As the MSA only has a SA6402 controller in it, i'm pretty sure this is causing performance problems in my systems as there is multiple systems on running on this device.

Can i see the performance of the actual MSA rather than the FC network/device? The FC network has a much higher throughput than the MSA's SA Controller.

The MSA1000 controller module is SA 5 technology.
