I've just took delivery of two new DL4300s to replace a couple of DL4000 who's lease expires in a few months. I'm a bit confused with the NIC configuration of the new DL4300s They seem to have 4 built in BT ports and an expansion card again with 4 BT ports, now which ones are the 10Gb!? As looking at the DL4300 specs I can't find a spec that has 8 BT ports either standard or high capacity versions!
