Pinned topic Network connection: x3650 M3 to x3650 M3

‏2013-01-07T21:14:32Z |
Interesting scenario that I'm trying to debug. I have 4 x3650 M3's stacked in a rack. Let's call them Server1 through Server4.

Server1 has a file, 476MB on it.
Server2 is able to copy the file from Server1 fine, at around 100 MB/s.
Server3 is able to copy the file from Server1 fine, at around 40 MB/s (heavier used server)
Server4 is able to copy the file from Server1 fine, but at only 700KB/s to 1.1MB/s

I have tried Server1 and Server4 with all combinations of NIC's in Auto sense or hard-locked at 1GB Full-duplex. Currently they are hard locked at that speed.

Now the trick to this. If I PUSH the file from Server1 to Server4 it goes fine at 124 MB/s average. So, what would cause a file pull from Server4 to Server1 to transfer at 700KB/s, but a push from Server1 to Server4 to average out to 124 MB/s?

Thoughts?
