Does anybody have any comparisons on running TSM V6.3 on the AIX platform versus Windows 2008 ? We have been running on AIX for approximately 15 years and our company would like us to convert to windows. Trying to give them a comparison in terms of hardware needed, disaster recovery times, etc...

Any reasonably sized TSM installation takes too long to practically convert in place so you are forced to install TSM 6 on a new server, start new backups and then export/import the old data. This is an ideal time to change platform in the process. Other than that take a look at www.butterflysoftware.com Regards Steve Steven Harris TSM Admin, Canberra Australia On 17/11/2011 8:43 AM, Hans Christian Riksheim wrote: > I am not of any help here but you say you are moving to Linux because > it is cheaper. > > Our Power servers running TSM accounts for less than 3% of the yearly > total cost for our backup infrastructure.

This server has 2 SL500 tape libraries attached via fiber. One is local and the other at a remote site which is connected by dark fiber. The backup data is sent to the remote SL500 library several times a day in an effort to keep them in sync. The strategy is to bring up the TSM DR server at the remote site and have it do backups and recovers from the SL500 at that site in case of a DR scenario. >> >> I've done a lot of reading in the past and some just recently on the possible ways to migrate from an AIX TSM server to a Linux TSM server. I understand that in earlier versions (we are currently at 5.5.5.2) of the TSM server it allowed you to backup the DB on one platform (AIX for instance) and restore on another platform (Linux for instance) and if you were keeping the same library, it would just work but apparently that was removed by IBM in the TSM server code to presumably prevent customers from moving to less expensive hardware. (Gee, thanks IBM!<sigh>). >> I posted several years ago about any possible ways to migrate the TSM Server from AIX to Linux. >> The feasible solutions were as follows: >> >> 1. Build new linux server with access to same tape library and then export nodes from one server to the other and then change each node as it's exported, to backup to the new TSM Server instead. Then the old data in the old server can be purged. A lengthy and time consuming process depending on the amount of data in your tape library. >> >> 2.

Our biggest problem with scenario 1 above is exporting the data that lives on the remote SL500 tape library would take much longer as the connection to that tape library is slower than the local library. I can probably get some of our SLAs adjusted to not have to export all data and only the active data but that remains to be seen. >> >> My question. Has any of this changed with v6 TSM or has anyone come up with a way to do this in a less painful and time consuming way?
