Is there any more information on this switch? How does it compare to quanta lb6m? Can't seem to find any reviews...
JC102B? Its comware 5 switch, uses same firmware as 5800 switches. Do the sold ones include PSU? I dont see it mentioned on ebay page.
normally these work with HP branded/compatible SFPs or DACs, but if you manually specify speed/duplex and dont mind occasional spam in log, you can use any.

thats good to hear about those transceivers. I had one H3C/HP dual-branded 5800 where link wouldnt come come up with cisco compatible DACs or cheap chinese SFP unless speed/duplex specified. Maybe they changed this behavior in newer firmwares.
Also they were promising comware 7 for these switches, even some preview releases were made public, but I know the issue was cmw7 needed that RAM upgrade you did to your switch. Not sure if they did official release, I see only v5 firmwares on download page.

Good find! If I didn't already have the Quanta switches, I would have picked these up. Now I just need something smaller - like 5 SFP+ and 5 1Gbps ports. Apparently it's a super rare combination and I can't find any switches with those specifications 
Shameless plug. I've a Brocade ICX 6610 in the FS section with 8x 10gbSFP+ and more than enough 1gbps.Good find! If I didn't already have the Quanta switches, I would have picked these up.

Ahhh, that's a good combination. I am actually looking for something with small amount of ports on purpose. So having that many 1Gb ports is actually a deal breaker
Gotcha. Its a hell of switch, with a very good combination of ports, but sadly, I've outgrown it. I'm on the other end of the spectrum. I need ~16 SFP+ ports, and not that many 1gb ports. Most of my stuff is either 10g now, or wireless.Ahhh, that's a good combination. I am actually looking for something with small amount of ports on purpose.

That may not be a requirement anymore:
Resilient RoCE Relaxes RDMA Requirements | Mellanox Technologies Blog
Still needs ECN and the newer Connectx-4 adapters.
Too bad us-xg-16 is too dumb to have any of those capabilities.
can this switch do that though ?
ECN is part of the IP protocol and has been around for over a decade. Doesn't need "switch support"...
RoCE requires a NIC that supports that capability, no matter what. The point is that I don't think you need to worry about the switch...
I bought one @ $200 and just received it. They sent it with no psu. I went back and reread the brief description and can't find anywhere that said it wouldn't have a psu.
I have reached out to the seller to get it resolved. I'll update with their response. It did come with everything else (rack ears, console cable, ground cable). It also looks brand new, no scratches or anything on it at all.

Yeah, it doesn't make any sense, especially since they have these listed as seller refurbished. After the brief exchange I have had so far, I'm wondering if the seller deliberately left out that fact. How much effort would it have taken to include a sentence that said these do not include psu??
