iLO 3 keeps dropping out

[gradgr1nd]

I've got six DL360G7 servers, and three of them lose connection to the iLO cards, either occasionally or fairly constantly. The servers are all ESX hosts, and I use the iLO dedicated port.

I've tried:

Change network cable and switch port

Update iLO to 1.5

Auto and manual settings on iLO and switch port

Factory default

5 of these boxes are identical models, but even the 6th drops out occasionally.

Here's a sample ping:

It's stopping vCenter from being able to power them on reliably.

Anyone got any ideas please?

Are you using the iLO3 dedicated NIC or Shared NIC?
