    Hello, We bought a used IS5030 switch from ebay. But only the top 18 ports can work and the rate is only 20Gb/s per port, even though we used QFP cables. It looks like a license problem.

    Hello all, I was thinking, for my living room where I have quite a few servers running (silent !), to do a custom 10gbe IPoIB setup. In my lab room I could use the Voltaire 4036 (non-E version unfortunately) which I still need to find a way to silence. It's way too noisy even for the server...

    Infiniband PCIe card preventing boot in one server but not another

    Hi, I have a weird problem. I purchased 4x used identical Sun QDR X4242A Infiniband cards (Mellanox MHQH29B rebrands) for my 4 node supermicro 6027TR-HTR (X9DRT-HF) server. 3/4 cause boot to hang at post code 91, which is when the PCI stuff is loaded. The fourth one seems to let the node boot...
