Actually, I just switched to that with the same performance. But I'll try to enable Jumbo; as of right now it is broken on the initiator server.

Sounds like latency issue to me. Check NIC properties for number of collisions it reports. No collisions, according to Linux. Not sure how to find that in Windows. Do you say that because backups are pausing (which is still happening) or because AoE was so slow? Because iSCSI is three to five times...

1) No Jumbo - no peformance. See my first post; I'm able to get 10MB/sec with netcat+cpio even while backups are running, so I don't think Jumbo is the limiting factor. I would be perfectly happy with 10MB/sec. I guess I could try NIC->NIC and enable Jumbo that way, but I don't think that is what i...

You should get wire speed. Enable Jumbo frames The switch doesn't support jumbo :-( make sure you have latest firware flashed into your CoRAID box. It's a Linux kvblade or vblade setup (both do the same thing). Does SMB of iSCSI over the same hardware works well? I'm just about to test an iSCSI tar...

AoE performance slowww

Problem I am averaging 1.5MB/sec. backing up data from my AoE setup. Sometimes I can get up to 4MB/sec., but that's rare. Only ONE client is pulling the files, there is zero multiuser access going on. Anyone have any thoughts? Target Software: vblade 18 OR kvblade alpha-3 (same results) CPU: 1.7GHz...

Update: iSCSI was way too CPU-intensive for the target, so I'm back to StarPort. Working like a dream now. That HP Multipath software must be buggy, but there isn't a newer version so I'll just have to pass on it and hope we don't lose a SCSI card. Bummer that we paid extra for the functionality...

Giving up: Cannot see anything in Disk Management

Summary: Even though two AoE vblade targets show up in StarPort, nothing is seen in Disk Management. I even created a RAM drive and it doesn't show up. I have a serious problem for which I need a SAN. It's 6:40p on a Sunday afternoon and I really need to get this thing working, so I'm giving up on S...
