Also with that few tape drives have you considered collocation. That way especially with LTO a small server and several incrementals will fit on one tape. Our CEO's PC is backed up using TSM with Collocation to an LTO drive and after a month of incrementals all his data sits on one tape. A test restore of his workstation took less than 3 hours. Also if you have over 100 servers you need to get more tape drives. I am sure TSM will wait. And while we're on this subject, we are looking at Disaster Recovery plans and the path we must take using TSM to recover a couple hundred servers. It looks bleak. We are finding that, due to incremental forever backups, recovery times are extremely long because of tape mount after tape mount after tape mount. In a real disaster, we expect to take an entire day or more to recover a single server. With a limited number of tape drives the recovery time required for 100 servers could take weeks. Has anyone else run into this dilemma? What is TSM's direction? How can I speed up the recovery process? John G. Talafous IS Technical Principal The Timken CompanyGlobal Software Support P.O.

Re: Expanding our system

TSM is version 4.2. We have about 30-40gig of data coming in over about an eight hour time window each evening and night. Things are fine for now. We are looking to do some improvements in the next several months. The 3494 can be upgraded to 3590E1A using direct Fibre Channel attach. I do not know if the 3490's can coexist with the Fibre Channel 3590's, but I do have customers that have 3494's with both SCSI 3490's and SCSI 3590's in the same library. They can not be in the same frame, but if they are in separate frames it works well. First thing we would like to do is to reload the server with Win 2000 and TSM version 5.xx. In our shop, we can only speak MS. Other OS's aren't an option. This we would like to do in 3-4 months. I think we can handle this ourselves. Next on the agenda, we are working towards getting some kind of a SAN in the budget for the first of the year. I don't know all of the details at the moment but they are talking about 3-4 terabyte capacity. Don't know how this will impact on new data coming into TSM. But the boss man wants to see about adding another complete library with two more tape drives. For 3-4 Terabytes in 8 hours you would need 10 SCSI attached 3590E1A's. For fibre channel you might be able to use less, but realistically you are probably running what 20 - 30 Windows servers. You will 10 drives just to be able to do the tape copy pools and DRM management The people we that installed our original system are gone so we can't go back to them for more hardware. Any suggestions on someone to do this for us?

Re: Ordering license upgrades

We are about to order more client licenses. The last time we did this IBM and/or Tivoli required us to tell them how the new licenses would be divided among different platforms: how many for Windows NT, how many for AIX, and so on. The charge per client license is the same regardless of operating system. The 'register license' command does not provide any means for distinguishing between Windows NT licenses, AIX licenses, and so on. Why in the world do we need to provide platform information in order to get more client licenses? So that Tivoli can know what clients are being used the most in customer sites. This allows them to get the right mix of support people and what clients should be patched and tested first. It also helps Tivoli developers develop business cases for improving clients. The Novel client is not as popular as the NT client, and look where all the development dollars are going.
