Hi all,
I have the following issue in my production environment (solved by now using 1Gb cards and switch)
2 HP Proliant DL380P with HP 530T adapters
1 Netgear M7100-24X
1 EMC VNXe315 with 10GBe ports
The connection scheme is as following:
1 lacp lag between the 2 VNXe GBe ports and Netgear, working ok with 9000 MTU
1 10Gbe Proliant port connected to Netgear
I can mount the NFS datastore, I can ping (no networking issues at first sight) with 1500 packet size and 9000
If I start virtual machines on this datastore, or when I'm copying files to it, I get All Paths Down and datastore disconnects, recovering after a few minutes.
During this time, vmkping to the VNXe is working perfectly, without loosing packets.
I suspect of everything, from the switch to the NIC driver... any hints on this?
Thank you very much in advance!
