Hi, Our backups are set for an absolute serialization. We backup and restore the same number of files and the same amount of data 42 GB. The TSM server is configured in a RAID 1E0 with a ServeRAID 4Mx adapter. The client is using a RAID 1. We are going straight to disk since our diskpool is 150 GB. We've tried formatting the partition that the diskpool is on in 64k blocks, but it hasn't proved much help.
Is there a case where the TSM DB can be TOO large? Our TSM DB volume is 1 GB in size and our recovery log is 250 MB in size. We have 4 GB of RAM on the TSM server, so we didn't consider this to be a problem. Thanks for any help. Please email me if you need more information. -Vin [EMAIL PROTECTED] -----Original Message----- Forum: ADSM.ORG - ADSM / TSM Mailing List Archive Date: Oct 30, 00:08 From: Seay, Paul <[EMAIL PROTECTED]> Actually, the 2048 TCPWINDOWSIZE is not supported in NT to my knowledge. It is supported in W2K at SP1 or 2, cannot remember, with a registry hack. Someone else will have to give the particulars on that. Be careful comparing restores to backups. Depending on what numbers you are using, you may get the wrong conclusions. Make sure it is the same files backed up that were restored. Also, look at where your backup is going to on your server. If it is going to RAID-5 storage pools, that is it. The write penalty on the RAID-5 Array is the cause of the backup delay. If you are going directly to tape, I do not know what the issue is without a lot more information. Paul D.

Faster Restore than Backups over Gigabit? Hi, We just installed Gigabit fiber NICs and an isolated gigabit fiber switch. Our restores have increased dramatically from 31.81 GB/hr (8.84 MB/s) to 56 GB/hr (15.6 MB/s). The backups are still around 35.5 GB/hr (9.8 MB/s). The TSM server is very powerful (NT 4.0 SP6a Dual 1.8 Ghz P4 w/ 4GB RAM, 150 GB RAID array) and the clients are (Netware 4.2 Quad XEON P3 w/ 4 GB RAM). (We've tried changing the TCPWindow Size in our dsmserv.opt from 63 to 2048 with no effect) We're running TSM 5.1.1.4 server and TSM 4.2.3 netware client. Any ideas? Please email me direct if you have any suggestions or need more information. Thanks.
