Adding SSD Read Cache after volume/LUN creation

[mr_vaughn]

SSD SED's are on back order for over a month.

I and going to create my Disk Pools on each controller.

each is going to get a SSD read cache.

We need to start data migration ASAP.

Can I create my volumes/LUN's on the diskpools and then add the SSD read cache later without affecting the data on volumes ?

Yes you can add disk-groups to a Pool at any time.  You can also remove them but that requires some timeframe to DRAIN all the data on the disk-group to the remaining disk-groups in the pool.  Caveat:  you need enough free capacity in the remaining disk-groups to retain all the data on the disk-group beng removed.
A READ-CACHE is a special disk-group in that it retains no unique data and is copy of the data retained on HDD and can be removed quickly.  Adding the READ-CACHE after the fact will take some time to fill the READ-CACHE and the performance of the system will gradually increase.
