ABR11 build 17437 poor 1GB/s ethernet / network performance / speed
We're unable to achieve reasonable network performance with ABR 11 on a dedicated backup server running MS Server 2008.
We tried all kinds of acronis tasks: backing up, replicating and even exporting. With all these tasks, backing up to or from different storage nodes (HP Proliant ML330G3, ML350G6) with managed vaults (dedup off) connected through 1GB/s ethernet, the maximum speed achieved is 14MB/s. We also tried a Synology DS1511+ as a target.
Different NIC's (pci 64bit) were tested and tuned to different NIC settings (checksum offload, chimney and jumbo frames). Drivers and firmware are up to date. PCATTCP shows 50 to 60MB/s should be possible.
We tried hooking up different disks with all thoughput speeds of over 60MB/s (large filecopy through windows share), even with SSD's.
No matter what we try, the performance maxes out at 14MB/s, while CPU remains well under 50%. Is there anyone achieving "normal" 1GB ethernet speeds and if so how? Acronis could you please look into this?
Hi Boris
The next step I would suggest is to monitor the task manager and Resource Monitor of both the source and target systems during a backup.
Check things on both sides (source and target servers) such as:
- CPU load
- Memory usage
- Network transfer rates
- HDD Response times
- Disk Queue Length
This should help try to locate the bottleneck you are currently facing, it's very possible the source machine might the be issue and not your target so best to monitor both during a backup to locate the issue.
All the best!
Did you already try to backup just to an unmanaged file-share on your Proliants (using an unmanaged vault).
This way all the data doesn't have to go through agent.exe and storageserver.exe.
Also note that storageserver will use only 1 core. On a Dual-Core system that means 50% is a maxed-out StorageNode. On a 6-Core with HT, 12% means maxed out.
Issue is partly resolved: USB3.0 implementation seems to be the problem, replication to of from network drive performance is normal as long as no USB3.0 device is used. USB3.0 issue is posted here: http://forum.acronis.com/forum/31859.
