For a late Friday email, the largest TSM DB I have worked with is 120GB. After about 80GB you may start to see performance problems. I would recommend 5-7 TSM servers for your implementation. -- Joshua S.

According to the TSM 4.2 Admin Guide to calculate the size of my DB I multiply that by 600 bytes.. 625,000,000 * 600 = 375,000,000,000 bytes = 375,000,000 KB = 375,000 MB = 375 GB There also needs to be an offsite copypool of this data.. According to the TSM 4.2 Admin Guide: 625,000,000 * 200 = 125,000,000,000 bytes = 125GB So my DB needs to be 500GB, yikes.. How big can one scale a single TSM server installation up to before you need to start thinking about additional TSM servers? I.e. in this instance can my TSM server even handle this amount of data? How much could it handle? Gerald Wichmann Sr. Systems Development Engineer Zantaz, Inc. 925.598.3099 w 408.836.9062 c
