Hi, Would it be possible to give some comments on next please ?
Because we are requesting some more diskspace (500 GB) for TSM on our mainframe our management is wondering why we do not run TSM on AIX where diskspace is much cheaper. I agree with them that diskspace is cheaper on AIX, but I think the total convertion/migration cost will be a factor x more expensive then the price difference in disk space Some figures about our current configuration : Primary pool is about 30 GB disk and 6 TB in Virtual Tape System (approx 6000 virtual 3490 volumes) Our copy pool is on 3590 tapes (copied during day time from VTS to 3590 on MAGSTAR) We have 10 3590 drives on our Magstar, but TSM can use a maximum of 5 drives during day time and only 1 drive during night Daily backup volume is approx 450-500 GB TSM Database is 12 GB +/- 150 clients (Windows, AIX ) TSM server version 5.2.4.0 If we could get 500 GB extra disk space for our primary pool then this could cover our total daily backup volume and the data could be copied directly from there to our copypool which would be MUCH faster iso our current situation where almost all data has already been migrated to our VTS and causing hundreds of tape mounts (physical tape mounts because VTS cache is too small to keep all TSM data and other data) If we should consider to move to AIX, I see next issues : - VTS can no longer be used with AIX - we will need more 3590 drives - we will need extra 3590 tapes for primary pool - maybe extra frame needed in Magstar - new AIX box of course - Z/OS - AIX migration issues ? - other points to consider ? Any comments (pro's and contra's) are welcome Has someone done this migration before ?
