In PowerPath you can see how many I/Os are going through each path, seen from the host.

In the switch you can also have a look at this using SANHealth (including graphs) and in the Clariion you can use Navisphere Analyzer to compare traffic between the two initiators.

The PPath GUI is the easiest.

Hello RRR,

Thanks for the reply. when i monitor both the paths i see this results. Is there a way to calculate bandwidht out of it.

path 0 ---> 1868 iops/sec and queued 38

path -->1  2688  iops/sec and queued 29

use perfmon on the host or look at port statistics on the switch side.

Hello,

I have no idea what is perfmon. Can you please explain it.

Oh, sir, you cut me to the quick!  I've used lmgtfy before, but never in a forum before! 

i could not resist not to

Boy and I thought I was going to be Rick Rolled

The pics don't work (they're pointing at your c drive). The values you gave, are these averages or a some random point in time values ? You should be able to see both HBAs doing about the same amount of IOps, so that's good.

In PPath you cannot see the size of the IOs, or the average of them, so there's no way to calculate the bandwidth from PPath. In Perfmon you can see this though.

Path 0 is higher than path 1 - with load balancing they should be about the same.

The vaules are IOPS, if you know what the IO size is you could estimate the bandwidth or you can use Analyzer on the array to collect the performance data (on PowerLink see Support Solution emc163368 "How do I enable Navisphere  Analyzer monitoring  in FLARE Release 24 and later?") and emc218359 for a list of all articles about using Analyer.

Also, the queuing seems a bit high - if you're using Qlogic HBA's you might want to check what the Execution Throttle is set for - EMC's recommended settting is 256, but that can sometimes be too high - see article emc204523 "What is the cause of high  Average Busy Queue Lengths (ABQL) on CLARiiON drives?" - this has information about the settings on the Qlogic HBA.
