Hi Wanda, We still use tape for the copypool, but this is now not a viable DR solutions due to the time factor to restore from tape. We are presently evaluating ISCSI and NAS solutions for a disk copypool at a remote site, using 1Gb Ethernet (we have dark fibre to our DR site). The two ISCSI products we have evaluated so far are Ipstor from Falconstor and SANsympthony from DataCore, both are great products. The NAS solutions we are presently looking at is NetWare 6's NSS (with CIFS since our TSM Server is W2K), it's looking really good since is can server up a 8TB volume and the copypool can use a device type of FILE. Novell's solution is also the most affordable (free since we are a big NetWare shop). Our Audit department has already given us the OK to go to disk for the copypool as long as it's offsite. I'll backup the db to the offsite storage also, so in theory if we lose our TSM server, i can build a new one restore the DB from the remote site and start doing restores immediately from the copypool, if the backupool is gone TSM automatically pulls files from the copypool. I hope to have this all in place in the next couple months (if not sooner) using ATA drive enclosures, right now i can get 3.2 TB for $10,000. i have $25,000 in the budget, so if i go with the NetWare NAS i should easily make it.
Let me know how this all sounds to you or if you have any further questions. john Synovus >>> "Prather, Wanda" <[EMAIL PROTECTED]> 01/30/03 05:11PM >>> Hi John, We have also starting looking at an all disk backuppool for the future. I am curious how you handle: 1) backups of your DB 2) disaster recovery planning/offsite backups Thanks!

It's grown to 4TB, we just keep adding disk expansion to the server as we need more storage (We are now looking at the new ATA Raid Expansion Cabinets 3TB for $10,000). We backup 377 servers (80 to 100 GB total) nightly and growing. The TSM database is 15GB sitting on raid 10 with 15K rpm drives (very fast) , i also defrag the DB monthly. This is a dream setup and works very well, restores run in the blink of a eye. I run the TSM server by myself as a part-time duty. The only problem you'll have is figuring out what to do with all your free time. The is a common topic on the list, search the achives at www.adsm.org. Let me know if you have any questions.

The goal being to eliminate going to tape. Does anyone have any really BIG disk pools? Are there tools available for managing large TSM disk pools over time. (IE: Reclamation, Aging Data, etc) The documentation from Tivoli suggests that we need to set it up as a device type=FILE. What are the drawbacks using this approach? Is performance dramatically impacted? etc...
