time to upgrade my friend.. 7.3.5p1.. That's very old..

Also, i never heard of a 7500 RPM SAS disk. .. B/c you have a 15K drive, you should replace with same

ok if the disc 10000RPM

When you mixed disks as per Netapp guide, the entire raid-group will lower to 10K.  If this is a low latency app, just proceed with caution

But you really need to upgrade these controllers.  You should focus your efforts on that.
