Re: DL380G5 with HP NC510C losing connection
We are experimenting a similar problem, may be not exactly same issue: we are not getting the "network cable is unpluged" icon&message, but the 10gig card is loosing connection every two hours or so. When we disable it and enable it back, it works fine again for a couple of hours.
Now we have switched back to the gigabit inboard card, because we have to work, but we really need this 10gig to work. Any a update of info would be much appreciate. Thanks,
antoine.
PS: we have contacted HP support, but no solution for now.

Re: DL380G5 with HP NC510C losing connection
Well first sorry I thought I had posted the "next step to our story".
So after a few try to tweak the gigabit settings without any success, HP sent a new NC510C (note that it was the second time we were going to replace it, as the first card didn't even start), but they said it is the latest build version of this gigbit card. We tried out and since we replaced it, the connectino hasn't been lost. That is nearly one month ago.

HP NC510C losing connection
http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1244786
The problem is the NIC doesn't function properly with >32GB RAM in the system, in my case Windows 2003 server x64, Proliant DL380G5. My server had exactly 32GB of ram. I took it down to 24GB of ram and it worked like a charm. Took it back to 32GB of ram and the connection started dropping again. The problem is with the NC510C (NetXen rebranded NIC)working in servers having more than 32GB of ram. Go figure.

Re: DL380G5 with HP NC510C losing connection
Not that it helps, but the RAM limit for the NC510 is higher under Linux.
Also, there is another "standup" PCIe 10G NIC on the HP CPL - the AD386A. It is there for HP-UX/Integrity systems but has been known to work under Linux/ProLiant. I cannot say if it has been tried under Windows/Proliant.
Of course that would all fall under:
Supported, known to work -> warm fuzzies all around
Supported, not known to not work -> an HPite may be in trouble
Supported, known to not work -> an HPite is in trouble
Unsupported, known to work -> lucky today, unlucky tomorrow?
Unsupported, not known to not work -> there but for the grace of Turing
Unsupported, known to not work -> no, it was not deliberate ;-)
Under Linux the card is driven by the cxgb3 driver - at its heart the card has a Chelsio T3C chip.

Re: DL380G5 with HP NC510C losing connection
I know this kind old thread but..
I got Dl380 g5 - NC510C
When files transmitting files like 10 - 15 GB size it takes long time to transmit the files almost 3 minutes
latest driver - firmware same issue
these are the NIC values
802.1p QoS Packet Tagging = 0
Maximum Frame Size = 8014 Bytes
Flow Control = 1
Tx IP Checksum Offload = 1
Rx IP Checksum Offload = 1
Tx TCP Checksum Offload = 1
Rx TCP Checksum Offload = 1
Large Send Offload = 0
Number of Tx Descriptors = 1024
Number of Rx Descriptors = 8192
Number of Rx Descriptors (Jumbo) = 4096
TaskOffloadLSOMaxOffloadSize = 64000
TaskOffloadLSOMinSegmentCount = 2
TaskOffloadLSOIPOptions = 0
TaskOffloadLSOTCPOptions = 1
TaskOffloadChecksumIPv4TxIPOptions = 0
TaskOffloadChecksumIPv4RxIPOptions = 0
TaskOffloadChecksumIPv4TxTCPOptions = 0
TaskOffloadChecksumIPv4RxTCPOptions = 0
Receive-Side Scaling = 0
any idea what could it be?
is there any table performance comparison to check if my NIC is OK? I mean maybe you guys are getting same time like
thanks a lot

Re: DL380G5 with HP NC510C losing connection
I am looking to deploy a similar solution on same hardware with Datacore SANmelody & wondered whether you could expand on the CPU issue & performance you were seeing.
Is your 10GbE NIC now stable? Are you getting good iSCSI performance? Has your CPU utilisation settled down? Are you running ESX/Xen on it at all?
This may be a bit off topic so if so let's start a new thread.
Thanks,
Simon.
