That seems to be really slow 8 gb per hour. I'm running TSM server on a h70 with 100mb ethernet dedicated backbone to my NT clients. These clients are mostly compaq prolient 7000. I average about 14-
Excellent analysis. No, the users would not tolerate this. So what are people doing about this? Nothing. Hoping. Praying. The good news is the RAID will save most of the days. But every now and then

Daniel, With LTO, your capacity is probably about 100GB native. Your 700 GB server might occupy maybe 1.5 TB of space due to file versions, depending on your retentions (my 1TB fileserver occupies 1.

This is a horses for courses problem. TSM across the network may not be the best solution for this server. Instead use some tool which can write to directly attached tape drives. If you want to use T

It is up to the (file) server administrator how he/she will setup, tune and maintain the node. 1 TB of data can be put on a single filesystem - it is up to you. In my practice I've even seen an Oracl

This test was performed during daily operations. This is usually the time when you need to do a restore. Therefore, the machine you're trying to restore won't be the only machine sending packets over

The bottleneck in a solution like this is probably not the 3584 drives, which, as you correctly suggest, should perform about 12-15MB/s. But, can the local area network perform this can of speed? A 1

Backupsets can be useful in some situations, but saving time is not one of their benefits. In the experiments I've done, generating a backupset took as long as or longer than restoring the client. Th
Yeah, and when you start to restore 512 byte files the performance will really go into the dumper. This problem is not about tape speed, network speed or disk speed. It's about software. If anybody h
On the wishlist item: I have heard talk about implementing an automatic multi-stream restore similar to what we have now with backup and resourceutilization. This will be slick but then only really s

Hi Kelly, your're right, a multistream restore is one of the items on top of our wishlist. Just one thought on collocation: With collocation you can't mount as many tapes as without, ok. But with col

Oops -- Forwarded by Robin Sharpe/WA/USR/SHG on 12/20/01 10:01 AM -- Robin Sharpe Robin Sharpe But wait a miniute.... doesn't the multi streamed backup work by allocating a session to each filespace
As can be seen, the notion of multiple restore is complicated. I'm sure that the Tivoli engineers are working hard on implementation ideas. I hope that they have lots of people that have seen various
