Dearman, Richard wrote: 9000 kB/s is only 9mb per second. Over a 100meg ethernet LAN. That doesn't sound to god to me. If you compare bytes to bytes, and bits to bits, you're getting 1200 megabits per minute on a system that has a *theoretical* throughput of 6000 megabits per minute. That's pretty damn good. -- Mark Stapleton ([EMAIL PROTECTED])
Re: 500GB Backup
From: Dearman, Richard [mailto:[EMAIL PROTECTED]] Why would I send the data to tape first writing to disk is faster. Burton, Robert wrote: Tape direct is a heck of a lot faster than disk Let's qualify that a bit. Since the major bottleneck in tape operations are file openings and file closures, staging the backup of a lot of small files to disk first, and then to tape later, is much faster than directly to tape. Large files are a different matter. The larger the file, the closer that tape speed approaches disk speed. As tape speed increases, it makes little sense to write to disk *and* then write to tape. The other reason to stage to disk first is if you're concurrently backing up multiple clients. Where does the trade off happen for your system? There are so many variables that it is almost mandatory to do some benchmarking to find the breakpoint. As has been said before, you need to go to gigabit ethernet, connected with a switch, and use TSM's multithreading to get maximum throughput. -- Mark Stapleton ([EMAIL PROTECTED]) -- Mark Stapleton ([EMAIL PROTECTED])
Re: 500GB Backup
You're getting you terms mixed up. 9000 kB/s is 9MB/s, as you state. A 100/mbps ethernet (fast ethernet) is bits-per-second, not bytes-per second. 100mbps=10mB/s, so if your getting 9mB/s, your doing quite well. This is your bottleneck. To get faster you're going to need gigabit ethernet, which is 1000mbps, or, 100mB/s. I run dual gigabit connections into our tsm server, a RS/6k-S7A. IBM's adapters seem to max out at around 30-35mB/s, or 20,000-25,000 packets-per-second. As soon as we get a new switch that supports jumbo packets (9k ethernet packets) I expect to see the packets-per-second drop and the throughput increase for clients that also have gigabit connections.

Re: 500GB Backup
Due to a temporary lack of disk we had to start writing backups from one of our large NT file servers directly to tape. we have two large NT file servers backing up at the same time. One going to SSA disk pool the other to a pool that is writing directly to 2 3590E1A's. TSM Server is hosted on a RISC/6000 H70. Both client machines backup up around 75-80 GB per night on average. They are both Compaq 6500's connected to IBM ESS for disk. In most cases the machine backing up directly to tape out performs the machine backing up to the disk pool. This is just comparing Total Elapsed Time and nothing else. Imagine that!

Re: 500GB Backup
The disks are not setup optimally. A DD to one 10K SSA disk to another can run a 30 Meg per second. Stripe across five drives and this will be even faster for a single system. The problem usually is the person that optimizes the disks does not optimize them for ADSM. If you turn on compression on the client, and you get 3 to 1 compression, multiply the disk speed times 3 that you are getting writing to the server now.

Re: 500GB Backup
When you say stripe across 5-6 disks are ou saying a RAID5 set. Also, I thought if you set compression at the client level, the data will not compress when it gets migrated to tape. Also, what do you mean by at the block level. Should you use JFS or raw filesystems for your ADSM volumes. -Original Message- From: Jeff Bach [mailto:[EMAIL PROTECTED]] Sent: Monday, April 30, 2001 10:52 AM To: [EMAIL PROTECTED] Subject: Re: 500GB Backup Easy to imagine, not take the same amount of money the tape drive cost and buy disk, stripe the disks across 5-6 drives and two controllers at the block level. Dedicate this resource to the one server for the backup period and run the backup. Which is faster now? Also compress on the client so we have an apples and apples comparison.

Re: 500GB Backup
If your tape storage is fast enough (you didn't mention what you have) you'd probably want to go straight to tape with the database backups. You didn't describe the client at all, but if you're using a TDP agent, the file sizes coming in would be fairly large, and you could set a Maximum File Size for your DASD pool that would be smaller than the backup data files coming in, and would force them to go straight to tape.

Re: 500GB Backup
We are backing up 2 servers of capacity 1.2 TB everyday. We have shark system and flash copy is implemented on shark. Without client interference we backup 1.2 Gig to TSM. It's running with 6 drives. No LAN/Free. But it's Client/Free backup. To restore we have placed Gbit Interfaces in Client and TSM Server. You need to give more information of your server and database. Are you doing incremental or full backup and which database you have? If incremental how much data is changed everyday? Can you afford GBit interface between data server and TSM?

Re: 500GB Backup
The amount of data is the same everday 500GB full backup. I'm using one SSA card in the tsm system. I could get Gig cards if I have proof that I'm maxing out the current 100mb cards in the system and I don't seem to be doing that. The tsm server is plugged into the same switch has the backup server and on the same ip subnet. Also, the database files that I'm backing up are just oracle dump files.
