I am not sure I understand. You want to build virtual TSM servers with no storage pools to funnel the data to a physical TSM with storage pools to reduce the workload on the physical server? What work are you trying to reduce since the physical server will still have the data on its network connection and on its storage devices.
Consider these random thoughts: iSCSI Library Managers are not evil K.I.S.S. Backups are for fun, restores are serious LPAR > guest Andy Huebner -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[email protected]] On Behalf Of Keith Arbogast Sent: Wednesday, February 02, 2011 1:01 PM To: [email protected] Subject: [ADSM-L] copypool-only TSM server on a VM I have been asked to evaluate the use of copypool-only TSM servers built on virtual machines. Virtual machines on ESX can't do I/O to tape devices, but the source server for a server-to-server copy pool does not need to do I/O to tape devices. It sends its files to the target TSM server which does the tape I/O. So, potentially, several TSM servers built on virtual machines could send virtual volumes to one physical TSM server target with tape I/O capability. Primary pools would be defined on the source servers, but they would be marked unavailable permanently. Each TSM server on a virtual machine would have two copy pools: one on-site and the other off-site; instead of an on-site primary pool and an off-site copy pool. The reason for doing this would be; to divide the backup load into smaller chunks across more TSM servers, to avoid buying more physical servers, and to share tape drives without using a Library Manager. A detriment of this setup would be that reclamation of the copypools would be degraded with no primary tape pools to read from. Are there other obvious or subtle problems with this idea? Or, is it brilliant?... Which copypool would restore files come from? How would that be managed? Our TSM license is based on TB in primary storage, so extra licenses are not a factor.
