MSA

[avamar]

if we connect more than 1 controller to MSA 1500 in active /active config how much will be data transfer rate from host to array will increase ?
MSA 1500 supports 30000 IOPS and 200mbsec bandwidth .

Unless one controller is currently a bottleneck in your system, I doubt performance will improve much.

If the disks are running flat out too, all the controllers in the world won't make much difference either.

For me two controllers is more about resilience, the A/A feature is a bonus.
