Your understanding is correct, from the Clariion perspective, both the Fibre Channel drives and the ATA drives are in the same storage group for the Celerra, (though different raid groups obviously). You can do this yourself, assuming you have the ATA tray installed, however it wouldn't hurt to have a CE help out. There are two manuals that are important to understanding LUNs and file systems using Automatic Volume Manager, "Managing Celerra Volumes and File Systems with Automatic Volume Management" and more importantly to begin with, "Implementing Automatic Volume Management with Celerra" you can find these on Powerlink.
Once you have added the ATA drives, you can create filesystems using the clarata_archive pool, and they will sit on the ATA drives, and not touch the more expensive FC storage.
Harold what you want to do is quite feasible, the sata disks will be added to the clarata_archive storage pool on the Celerra, (currently you are most likely using the clariion_r5_performance pool). You can create filesystems specifying the clarata_archive storage pool on SATA disks. The recommended settings for tiered storage are high performance FC disks for your day to day data, SATA for less important, but volatile data, and the Centera when you don't need to change the data or need it on high performance disks.
Thanks, that's what I was looking for. Would the EMC CE be the one to set up the clarata_archive storage pool or would I do that myself? I'm about 3/4 competent on Clariion/Celerra at this point.
If I understand, the ..r5_performance and ..clarata pools will both reside in the same Celerra Storage Group gracefully and I will be able to create file systems exclusive to the sata drives.
Sorry to belabor the question, just looking to glean some knowledge.

That just about covers it! Thanks, this is just exactly the kind of response that makes these forums worth while.
