I have two machines direct-connected each with an Intel gigabit NIC. Initiator:
Linux home.copilotco.com 2.6.18-xen #1 SMP Wed Jun 13 22:25:31 PDT 2007 x86_64
x86_64 x86_64 GNU/Linux
aoe: AoE v64 initialised.
aoe: e0.0: setting 8704 byte data frames
aoe: 0030486678dc e0.0 v400a has 629145600 sectors
etherd/e0.0: p1
Target:
Linux localhost.localdomain 2.6.18-92.1.18.el5 #1 SMP Wed Nov 12 09:19:49 EST
2008 x86_64 x86_64 x86_64 GNU/Linux
running vblade-19 and qaoed v0.81 (they both produce the same results).
They both have mtu 9000 although I have tried with 1500 with same results.
No errors of any kind on any interface. No errors, drops, overruns, frame,
carrier, etc.
Throughput is extremely slow due to lots of AoE errors:

I tried switching out my initiator machine for a laptop with a 100Mb
1500 mtu interface running Fedora 9 and AoE module v64 and dropped the
mtu on the target back to 1500 so they would talk got the exact same
results. So the problem would not seem to be my initiator server
unless there is a problem with AoE module v64. I don't think it could
be a layer 2 problem because I have no errors on any interfaces but I
swapped out the ethernet cable just in case with no effect. It always
gets a gigabit link. I am using hardware flow control and mtu 9000 on
both ends of the link although I have tried it without flow control
and mtu 1500.
When I modprobe aoe on the initiator I see the usual in dmesg:
aoe: AoE v64 initialised.
aoe: e0.0: setting 8704 byte data frames
aoe: 0030486678dc e0.0 v400a has 629145600 sectors
etherd/e0.0: p1
Does it matter that I don't have a switch in here? I don't see how it
would...I've run direct-connected systems before with no troubles.
