My file cluster also hosts the backup software. It pulls data from all the other servers and pipes it through the SAN to the tape library.

As it turns out, the Remote Agent is what's causing the problem. Go figure. We backed up a 1GB file, and that took, and I'm not kidding, 25 minutes. We then bypassed the agent (stopped the agent service, and configured the backup job to not use the agent), and it completed in 35 seconds!!!!!!! I cannot tell you how F'd up this is. Yet, another reason why NEVER to use CA products. Also, this was finally found out when I asked to be escalated to Level II. Oh, and they also told me to re-install the remote agent with the default settings. With your other 3TB, what are you using to back that up? The same server that you use to backup your SAN? What versions are you running?

It takes over 15hrs, but that's because we have close to 10 million files. The next version (due out in December) will handle numerous small files more efficiently. We've been told we should see at least a 50% in backup time. To be fair, we have about another 3TB on other servers and they complete their full backups in under 4 hours. Based on your 110MB/min, it's taking you a little over 10hrs. Correct? Your setup is similar to mine except my servers are Compaq DL580 (quad 2.0 GHz). The Gb Nics are Broadcom-based. We use Compaq branded HBAs to talk to our SAN. Tape library is SAN attached. Hard disks are Ultra3. adam --Original Message----- From: Chris Lynch [mailto:lynch00@xxxxxxx] Sent: Friday, October 24, 2003 3:51 PM To: thin@xxxxxxxxxxxxx Cc: john.rowlandson@xxxxxxxxxxxxx; 'Braebaum, Neil' Subject: [THIN] OT: Really slow throughput with CA Brightstor ARCserve 9.01 What do you guys use to backup your cluster? ARCserve, or BackupExec, or something else? What hardware are you using? What kinds of throughput are you seeing on you backups for the cluster? Basically, I have a throughput issue with ARCserve 9.01. While this is not my choice for backups, I need to resolve this issue. We have about 63GB of data to backup, and we are seeing about 110MB/minute. Now, you need to know something about the setup here. Backup Engine Server (1DC) ------------------------- Dell PowerEdge 2650 Dual PIII-2.0GHz MP XEON 4GB of RAM Broadcom GB NIC running at 1000MB/s with Full Duplex Windows 2000 Advanced Server with SP3 PERC3/di - RAID1/RAID5 (OS/Data) Cluster Server (cluster name: 1POCDATA; Cluster Nodes: 1POCFPA & 1POCFPB) ----------------------------- (2) Dell PowerEdge 2650 Dual PIII 3.06GHz MP XEON (533MHz FSB) 4GB of RAM (DDR) Broadcom GB NIC running at 1000MB/s with Full Duplex PERC3 and PERC4 - RAID1/RAID1/RAID5 (OS/Quorum/Data) Now, 1DC has the PERC3/di (which is the Ultra160 Controller with Ultra160 10K RPM drives) The cluster nodes have Ultra160 drives onboard, but the shared storage drives are Ultra320 on the PowerVault 220s (which is then connected to the PERC4 RAID card, Ultra320 performance). I contacted Dell to make sure nothing was wrong with the hardware, and we found nothing. We tested copying 5.5GB of data from 1DC to the cluster share. That took about 11.5 minutes. Then, copied the same data back from the cluster to 1DC. That took under 9 minutes. CA gave me the following reg keys to add to the cluster nodes: HKLM\software\computerassociates\BrightStor\client agent\parameters 1. change the decimal value for Maxsendpacketsize to 8192 2. change the decimal value for RecDaemonbuffercount to 800 3. change the decimal value for Receivetimeout to 4800 4. change the decimal value for sendtimeout to 4800 5. change the decimal value for setwsrecdbuffersize to 64 6. change the decimal value for setwssendbuffersize to 64 7. change the decimal value for setwstcpnodelay to 8 On the client agent admin window, select configuration and set the backup priority to high. I did this, but this has made the throughput worse. Man, I wish I had Veritas here. Oh well. Thanks for any input you could offer.
