Hey,
So this is totally anecdotal, but I thought I saw someone who said they were able to flash their ConnectX-3 VPI with ConnectX-3 Pro firmware
I've seen other threads where people said they were NOT able to do this
Looking over the PDFs for the three models, they don't really look any different as far as their feature sets. Can someone be a tie breaker and let me know whether or not they've gotten this to work?
I was able to flash some QCBTs (10/40) with FCBT (40/56) firmware easy enough, so if someone says they were able to go all the way to the FCCF (RoCE v2) firmware, I might have to try it...
The main advantage would be in ESXi the "regular" CX3s can't do RoCE v2 in ESXi, while the "pro" ones can, apparently...
The models I'm talking about are:
VPI:
MCX353A-QCBT (single QDR) / 354A -QCBT(dual QDR) - the 10GbE/40Gb IB models
MCX353A-FCBT (single QDR) / 354A -FCBT(dual QDR) - the 40GbE/56Gb IB models
Pro:
MT27524A1-FCCF-FV (single QDR) / MT27528A1-FCCF-FV (dual QDR) - these are also 40GbE/56Gb IB like FCBT afaik but support RoCE v2 and may or may not have a different ASIC (? Can someone confirm?)
