We are not using a RAID5 on ANY drives. They are all RAID1 or RAID1E0 (spanned RAID1E). Unfortunately I can't load an FTP server on the Netware server without a LOT of red tape. I'm not necessarily thinking it's the network since I do get great throughput doing a restore. Thanks.

Faster Restore than Backups over Gigabit? It's been mentioned that it is probably the RAID5 on your TSM storage pool. To rule out TSM, simply do a FTP from the client to the same disks on the server and see what throughput you get. -----Original Message----- From: Vin Yam [mailto:vyam@;QBCT.COM] Sent: Tuesday, October 29, 2002 7:16 PM To: [EMAIL PROTECTED] Subject: HELP! 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.
