On the SP's you could use the switch to get fast backups. On a large P5 with VLAN and TSM on the same box you can also. You can also use p5 VLANS and a dedicated large packet NIC going to a similarly configured NIC on a TSM server. But with more people doing Lan-free..........

The reason I posted this is that up to now, I've never seen anyone go any faster than about 400 MB/s (3200 Mb/s). If you're able to test that you can go indeed go anywhere near the speed that this guy had, using your P5s of course, I'd love to post your results, too. I'm just trying to help get the backup community beyond the 100 MB/s barrier we've been at for a while. --- W.

I monitor several backup-related mailing lists, and a user on another list is getting 7500 Mb/s on his 10 GbE card and was willing to share how he did it.
We don't have a back to back 10Gb connection, but we do have 3 1Gb servers going into a foundry switch, which has a private 10Gb connection to our TSM server. We achieve 1590Mb/sec. 6 TSM image backups streaming, two from each server, going directly to 3592 drives. P5 - 570 TSM server, does not break a sweat, and I'm sure more is possible.
It's a NetBackup user, but that's not what the post is about. It's about how he got 7500 MB/s into a single backup server, and how he did it is just as relevant to TSM users: http://www.backupcentral.com/content/view/146/47/ Has anyone accomplished this kind of throughput on other platforms? (He's using Sun Solaris.) --- W. Curtis Preston Backup Blog @ www.backupcentral.com VP Data Protection, GlassHouse Technologies
