Solved: HP DAC Copper Cable with Cisco 4900M

abbas.ali · ‎04-03-2012

We have HP C7000/VC-Flex 10 Module that I would like to connect to our Netapps NFS datastore. The Cisco switch that I will be using between HP Flex-10 and Netapps is Cisco 4900M. I have a HP cable AP784A direct attach copper SFP+ to SFP+. Which module I need to purchase and insert into my 4900M to support 10Gb connectivity via HP DAC 10Gb cable.

Please Advise!

You need

4900M 4 port 10GE half card with X2 interfaces (WS-X4904-10GE)

OR

4900M 8 port 10GE half card with X2 interfaces (WS-X4908-10GE)

WITH

Cisco OneX Converter Module Converts an X2 Interface into One SFP+ Interface (CVR-X2-SFP10G)

I would recommend you to use following DAC cables from Cisco.

• SFP-H10GB-CU1M: 10GBASE-CU SFP+ Cable 1 meter (Version -02)

• SFP-H10GB-CU3M: 10GBASE-CU SFP+ Cable 3 meter (Version -02)

• SFP-H10GB-CU5M: 10GBASE-CU SFP+ Cable 5 meter (Version -02)

Responding to a post 6 years old, but received following from HPE when wanting to connect HPE DL380 Gen10 to Cisco Nexus 31108PC-V via Direct Attach/ Twinax Cables:

HPE:

I’m afraid the mentioned X2A0 is not supported neither with 562 NIC’s nor with the Nexus switches.
All the cables that can be used with these NIC’s are listed in quickspecs but unfortunately since we’re talking about 3rd party switch connectivity the DAC cables aren’t really supported in this case.
We cannot confirm that the Nexus switch will support our cables. The recommended and supported solution would be to use 10Gb SR transceivers on both sides of connection and LC-LC optical cables.
HP BladeSystem c-Class 10Gb SFP+ SR Transceiver - 455883-B21 can be used with 562 server NIC’s.

Follow up again from HPE:

As I mentioned previously 3rd party cables are not officially supported with our hardware.
The recommended supported way to connect our hardware to 3rd party switches is by using transceivers and optical cables instead.
There are no Cisco DAC or AOC cables that would be officially supported with 562SFP+ NIC’s. The customer can still try to test them and use them under his own responsibility but HPE will not support this.
