The estimates were 50-75GB daily (not 1 TB daily), 22 clients - a pretty simple load for W2K.

The suggestion to go with the OS you have more in-house expertize (i.e. Win) is still valid. However moving 1 TB you approach the limits of Windows. Dig down the list archives and you will find a lot of discussions, my personal opinion is that Windows should be used for up to 0.5-1 TB/24h. Right now your estimates are for 1 TB, they will not decrease in the future, and getting better service (performance / reliability / flexibility) users tend to put on some unexpected additional load. And main reason is not the performance as many people argue, but availability and flexibility. Doing devices maintenance on Windows without reboots is like walking on thin ice. And TSM experience showed that instead of benefits Windows PnP functionality generated additional problems. Bottom line: even with small or no AIX knowledge in house, do not take AIX out of the equation. Later migration from one platform to another would be hard, non-trivial and time-consuming task. For your requirements newer pSeries 630 or some existing pSeries 660 with 2 processors ought to be a good answer. Another point - SCSI vs. FC drives: Even if you start with single TSM server and all clients doing backup over LAN, consider FC-attached drives with or without SAN hub/switch despite small investment increase. Performance figures of *same* drive are better with FC-attachment. Later migration of bigger servers (Domino and MS SQL are good candidates) to LAN-free would be quick and easy.

Here are some more details on our environment: We will initially be backing up 22 nodes, all of which will be a mix of Windows NT and 2000 file servers. One will be SQLServer on W2K and one will be Domino 6 on W2k. We also want to look at backing up Macintosh design systems as well as laptops/PCs for power users. Overall, a total of about 1T will be backed up with approximately 50-75GB written to tape daily. We'd like to keep about 4 to 5 file versions on disk as well. Some of the nodes are local to the data center but many will be pulled accross the WAN (frame relay, 512k). Our local Tivoli rep ran the numbers and told us it shouldn't be a problem. We haven't purchased any hardware yet for TSM, as management wants to be sure we pick the right combination. I am leaning towards TSM server running on Win2000 because of our current in-house expertise. We are excited about the capabilities of TSM combined with an estimated $100k savings over the next year in hardware replacement costs alone.

I have about 200 nodes (AIX, NT/2000 & Netware) backing up about 200Gig a night & am using an IBM M80 with 4 3590 E1A's (soon to be 6 H1A's).......

We are in the process of ditching our current BackupExec/ArcServe setup in favor of a central TSM environment. We have decided to expand our existing 3494 tape library (additional frame w/ 2 3590 drives, SCSI) but haven't selected the hardware/operating system for the TSM server. These are our options: Dell 2600/Win2000 pSeries/AIX iSeries820/PASE Any recommendations for one system over another for the TSM server? The Win2000 option would be the cheapest but would it cause headaches down the road? thanks, Mark Cini Systems Administrator CorrFlex Display & Packaging
