redistributing drives between shelves.

Currently we have 3 x 24 drive enclosures on our compellent array and we're about to add 2 more.

The current config is:

Enclosure - 2 : Drives 1 - 24 = 146GB 15K

Enclosure - 3 : Drives 1 - 24 = 146GB 15K

Enclosure - 4 : Drives 1 - 12 = 146GB 15K, Drives 13-24 = 1TB 7.2K

Being added next week:

Enclosure - 5 : Drives 1 - 12 = 146GB 15K, Drives 13-24 = 1TB 7.2K

On order:

Enclosure - 6 : Drives 1 - 12 = 1TB 7.2K

Since each drive type in an enclosure requires a dedicated spare, is it possible to redistribute the 146GB and 1TB drives in enclosures 4 & 5  so that each 24 drive enclosure contains only 146GB or 1TB drives?

The goal is to reduce the number of spare drives required and add more spindles for increased I/O.

Thanks.

    Hello,

    Yes you can move the drives around in the different enclosures as long as there is no configuration on the drives.  If you want to move drive that have a configuration on them then it is best to contact Compellent  to have them assist you in the best way to move the drives with Data on them phone# 1-866-397-8673

    Let us know how it goes

    Where did you hear that you need to have a hot spare for each drive type in each enclosure?  This is a good practice, but not a requirement of the system.  I have 3 15k enclosures with only 2 spares, theres no need for more then that.
