Hello All,

Does anyone have any suggestions on getting some DAC(Direct Attached Copper) cables supported for our 7200c(3.2.1 MU2 P07,P10,P11,P12)? We currently have a Brocade 6470T-1G and are using the 40Gb breakout cables(they are 40Gb QSFP+ to 4x10Gb copper SFP+ connection which plug into the iSCSI 3PAR ports). The connectivity is fine and we are having no performance or connectivity problems, however that cable is not on the quickspecs list of cables and therefore is throwing the unqualified SFP error and showing the port as degraded.

We have already spoken with Brocade and they are willing to work with HP on getting cables supported, however who from the HP side should we reach out to?

The supported DAC cables are called out explicitly in the quickspecs to try and avoid this situation, it looks like a reasonable sample of HP, 3COM, Brocade and Cisco are now supported so they're continuing to expand support.

In order to get this supported you really need to speak to your HP Sales / Presales team and request they file a CER, if accepted this will provide documented support should you have issues with an unqualified configuration. At the same time ask to see if this can be pushed for qualification, until then you will have to live with the error (supported under CER) until HP/Brocade get around to qualifying and and releasing a patch.

Since they've already qualified some of the Brocades your chances are probably pretty good that this will be supported going forward.
