Bad performance EVA3000 and SQL2k and Exchange2k server

My SQL server performs bad on a EVA3000. Due to costs we have a RAID5 on the EVA3000 (we know this is giving poor performance), but I have read that you acn align track on the disk with diskpar.exe.
Does anybody know how may sectors are there on a track in the EVA3000 SAN? How can I align my VDISK with diskpar?

Marc:


The default is 63. Make sure you have a backup of the data before using diskpar, unless you do not need the data. Diskpar WILL make your disk useless until you format it again.

Also, make sure you do a FULL format, not a quick format when your done with diskpar.
Exchange tends to work better on drives that have been fully formatted, that is... Exchange Performance is better.
