EVA8000 performance

[okyour]

Hi all

I have a question here. how can i monitor the performance of eva8000?I use dd for database migration,but sometimes it reach 200MB/hour ,sometimes it is only 40MB/hour?anyone can give me a suggestion to find out if it is the reason of other machine use eva8000?
I need the real data to prove it.

thanks for your time

Check to see if you have EVAPerf on your management station:
C:\PROGRA~1\Hewlett-Packard\EVA Performance Monitor>evaperf

That will show you all the flags you can do. Everything from physical disks, controllers to vdisks.

Hi okyour,
Install EVAperf in your management station, which will give you the graphical representation of read & writes and effective load. It is an effective tool for EVA performance analysis.

Thanks and regards

Your performance in MB/s very much depends on things like
- number of disks of the disk group your source and target LUNs reside
- IO size (8kB ... 512kB)
- IO capability of your server doing the dd
- other workload on this server and the EVA

With EVAPerf you can really see the various EVA performance metrics.
I suggest you have a look at the Command View User Guide in the Performance section 6
