I've got one 30 GB TSM data base, 4 others are smaller. I'd guess you are slightly above average, but I have no actual stats to go on.
I strongly agree with the previous post that you should double check your retention settings to see if you are keeping too many versions of files, and check to sure expiration is running to see if you can slow down your DB growth rate. As far as what is "too large", it depends totally on your hardware/software combination, and whether you are happy with your performance. As hardware gets better, TSM sites are reporting satisfactory results with larger data bases. As the DB grows, TSM sites generallly start reporting complaints about expiration, reclaim, and/or DB backups running too slowly to get done in a timely fashion. You certainly can't grow the DB indefinitely. I expect you will start to choke long before you get to 100 GB, so I would worry about my growth rate, if I were you. Regarding the tape library issue, I assume your library is defined as LIBTYPE=SCSI (to check, you can do: Q LIBRARY libname F=D). TSM does not support mixed device types in a SCSI library. -----Original Message----- From: Miller Dave (RBNA/CIT1) [mailto:[EMAIL PROTECTED]] Sent: Monday, July 15, 2002 4:51 PM To: [EMAIL PROTECTED] Subject: General TSM Q's Hello All, We have recently deployed TSM at our site. Being new to TSM, I have a few questions I was hoping someone may be able to help with. I am running TSM 4.2.1.9 with a Compaq ESL9198DLX on W2K 1) Our TSM database has grown surprisingly fast. We tend to backup LOTS of little tiny files and as a result our Database is currently around 30Gb. I understand that the technical limit for the DB is somewhere around 5TB. Should I be concerned running a 30GB database on NT using a single server? Would this be considered a small, average or large TSM installation? 2) We've also found that our library is a little under-sized. (I regularly find myself exporting tapes from our primary tape storage pool to make room for scratch media). I would like to replace two or three of the DLT40/80 drives in the library with SDLT units. The ESL9198 hardware will support Mixing DLT and SDLT drives and media. Does any know or have experience setting up a library with two media types? Would TSM support this type of environment? Any help or information anyone can provide would be greatly appreciated!
