I use DIRMC via CLOPTSets for Windows & AIX clients; one server with about
20-30 clients is using abit over 400 MB. We started with 50 MB, and that's
probably okay, given the ultimate solution -- I am set at 1.3 GB with 34%
utilization... my DIR_FILE has grown to just under 2.0 GB (can you believe
there are that many directories being thrown around??? With only 3 million
files/objects in backup storage, it's nearly half the size of the TSM server
database... yikes!!!)
Do note that offsite (ie, copypool) reclamation can be a performance
nightmare; it's been discussed on this list -- the "fix" is to use a SEQ
device class (on disk) we call ours DIR_FILE, which is the nextstg for
DISK_DIRS. Daily disk migration now includes this one, so now large numbers
of directory restores *and* copy pool reclamation both run quite fast with
minimal tape mounts.

Subject: Re: Diskpool size for DirMc
Raymond,
I have a diskpool set up for exactly the purpose you are interested in. I
wanted to bring directory data availability up. I specify in the dsm.opt the
dirmc option and it does go there. I do back up that disk to tape in case of
disaster also, but don't migrate the data off.
I have close to 120 clients, lots of databases; notes, SQL, Oracle, lots of
NT and some Unix. I had little to go on for size so I set up my disk at 33gb
and waited to see how it filled. Looks as though I probably went way
overboard on this but for now I'm going to leave it as is. Here are my
statistics so on the disk:
/adsmstg11/diskvol.11 DIRECTORY-DPOOL DISK 33,000.0 1.7
On-Line
At 1.7% utilized it looks as as though I'll never fill it up but who knows.
I'm comfortable leaving it as it is for now since I'm not hurting in any
other areas for the disk space.
