Storage Group for Celerra Question
This is my first post to this fourm and hate to have it sound (to some I'm sure) dumb, but I haven't been able to get a straight answer from the docs.
We have a CX700 with a NS704g that was set up with "clar_r5_performance" disk pools. Everything works fine; able to expand; much easier than previous. Now I'm looking to adding additional disks to handle "2nd tier" storage such as manuals, docs, etc. that do not require high speed access but are more volitile than stuff we put on our Centera. So, my question is, can I put in a tray of SATA disks; set up a R-5 raid goup; drop it in our "CELERRA" Storage Group; and then create specific file systems on this raid group without causing a problem with the "pooled" raid groups? I don't want the SATA disks in the pool because I want to be able to selectively put 2nd tier storage on them.
Hope this question makes sense to someone.
TIA

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.
Cheers,
Patrick

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.

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.

These raid groups will show up as your clarate_archive storage pool.
