Re: Performance measuring tools for EVA8000
I wondered if you had any vraid from the same diskgroup mounted on any other server and their performance? (The IOPS of a diskgroup is decided by the characteristics and number of disks in the diskgroup)
Also check how busy is the controller thats owning the vraids in question (I am not quite sure how you find out the vraid/lun ownership in eva)
Earlier I had faced similar problems with sun boxes and the fix was an hba driver upgrade.

Re: Performance measuring tools for EVA8000
I agree with avik though - more than likely this is a host driver / configuration issue.

Re: Performance measuring tools for EVA8000
You could try the following as a starting point for performance measurement:
- You could use Storage Essentials (if you have it) to graph and monitor the controller and FCA port utilisation for the Sun server as well
- You could use Evaperf from the SMA or a storage server and monitor the performance characteristics of the suspected Vdisk in question - correlate your OS level disk device at Solaris end and Vdisk at the EVA end by Vdisk WWID.
- You could also use iostat at the host end to capture performance statistics
- As suggested before, you could also use basic "portperfshow" command on the attached swtich port of the server
