Re: [Veritas-bu] 10GB network + perf questions etc
If it's the card I'm thinking about the TCP checksum is already offload to hardware. In fact most gigaswift cards support this today with 1 Gbit technology. I think a great deal of tuning would be required to achieve anywhere near 10 GB w/ a single TCP stream.

They can do about 250 MB/s and have the box still function. They can get it up to 400 MB/s, but when they do that, the box won't respond. They couldn't run top, they can't login, they can't run ps, etc -- NOTHING. So I'm thinking that with Solaris, you're not going to get anywhere near 10,000 Mb/s (1200 MB/s). Maybe with Linux or Windows and a TOE (TCP offload engine) NIC, you might have a chance. (I only say those OSs because that's where they're making TOE NICs.)

Re: [Veritas-bu] Has anyone run a database consistency check recently?
In windows you can run this command. C:\Program Files\VERITAS\netbackup\bin\bpdbm -consistency f:\catalog.consistency.txt On a *nix machine it should still be the same command While it checks the catalog it will move corrupt entries to C:\Program Files\VERITAS\netbackup\db.corrupt and your catalog backups will complete. Using this command to do the consistency check and fix it does not delete the corrupt entries so if a fix for the corrupt entries ever happen you still have them. On our catalog it takes approxamately 2 hours to run. Our catalog is 60+ gigs.

Should be fine the master is just telling the clients/media servers what to do and where to send the data. As long as you have no tape drives attached to it-- however, if you backup millions of files those files will be written to in the catalog on the master.

[Veritas-bu] Backups getting status code 52 while vaulting is running.
All, Ok, I have a NetBackup 5.1MP6 environment with 27 Media servers that only back themselves up usually for ORACLE databases. I have 1 L700e with 11 9940B tape drives, and a EMC CDL720 which is a virtual tape library. I backup to the CDL and vault to the L700. I have always done the alternate read configuration so that my vaulting all occurs on the master server. Let's take 3 media servers which had a virtual L700e with 20 drives configured for them and the master server. The master server had 4 dedicated tape drives, and each media server had 4 dedicated tape drives. I had the master server have 4 drives for backups and to access the tapes from the 3 media servers during vaulting. ** Now ** I have configured that robot that had 20 total drives as SSO drives. The master server, and all 3 media servers have access to all 20 drives. In the past, when a tape was in use from the virtual robot by vaulting the backup would just say it could not find the tape and continue. Now that we have the whole robot in SSO, the backups are waiting for the mounting of the tape and timing out instead of going to the next available tape! Does anybody know how to avoid this issue?

Re: [Veritas-bu] 10GB network + perf questions etc
Hi I have 3 media servers running with a 10 GbE NIC (alll running RHEL4). Two of them use a Intel NIC, and the other uses a NC-510F (NetXen chipset). We use 3 different server models: a Sun V40Z, a IBM x366 and a HP DL580 g4. On my opinion, Intel(or AMD)+Linux machines have a so much better cost/performance ratio than anything from SUN (extremely expensive for the doubtful quality of their service and products). All of server reach a peak of around 2-2.5 Gbps (250-300 MB/s). Using iperf, we could reach 3 Gbps using NC510F; unfortunately, it seems that the 64-bit version driver is buggy, and we're obliged to use a 32 bits OS on a machine with 16 GB of RAM (which is very bad), which, I believe, strongly affects netbackup performance. I do NOT recommend this NIC at all. rgds On 8/13/07, Dominik Pietrzykowski [EMAIL PROTECTED] wrote: Hi Group, Just curious to know if anyone is using 10GB network (fibre/copper, is copper available yet at 10GB ???) on their media servers or clients and what sort of data transfer rates are they getting ???
