I was wondering who else has done this recently and if there are any good sources of inf. on the net that may be of help to me. At the moment we have TSM Server 3.7.3.8 running on a Sun Solaris E250 (400Mhz, 1GB memory). We have 28 client running on Solaris, OS/2, NT and one Linux for good measure. We have one 3494 tape library housing two 3590 tape drives (J Tapes - 20Gb compress, 10 uncompressed). I can easily work out approx. how many tapes we are going to need; how much free space we have in the library; how much disk space we may need for the database, log etc. But the thing I need help with is figuring out how much client data we can back up within a certain window. All clients seem to have different rates at which they can process data; some machines are remote; some use compression etc. etc. etc. I'm am quite new to this and would be interested in other peoples experiences in doing this kind of thing. I guess there are so many questions that to sit here and type them all would be foolish. I'm more interested in finding out what the crucial questions I should be asking are (are you still with me, I know I'm rambling now). Also, I'm interested in learning more about the tuneable parameters within TSM (Server and Client); what sort of things I could do to improve data throughput, database performance, tape performance etc. Basically, any help, pointers etc regarding this type of thing would be very much appreciated.
