Do older ConnectX Rev A0 QDR HCA support the 2.9.1 firmware?

Hi! We have several SuperMicro 6026TT-IBQF that have the old Rev A0 ConnectX QDR adapters (lspci shows MT26428 as the PCI DevID). I checked with SuperMicro and was told that Rev A0 only supports firmware 2.7.2. Is this really the case? It looks like from the Mellanox website, it should be able to support 2.9.1. When I run ibv_devinfo, board_id shows SM_2091000001000, so I’m not sure which firmware I should use from this link to test: . There are at least 3 firmware images available, all have Mellanox-specific PSIDs and none are for Rev A0. Help! Regards, Mark

Hi Mark,

unfortunately SuperMicro are the only once able to provide FW for their rebranded card.

did you try contacting SM support?

BTW, similar Mellanox chipset can run with 2.9.1000 FW…
