New testbed installed

Since I changed jobs, I left behind a lot of my test systems, but I now have a couple of test systems set up. Here is the rather crazy set of non-chipset devices I now have in one box:

$ lspci -nn|grep -v 8086:
03:00.0 InfiniBand [0c06]: Mellanox Technologies MT25208 [InfiniHost III Ex] [15b3:6282] (rev 20)
04:00.0 Ethernet controller [0200]: Mellanox Technologies MT26448 [ConnectX EN 10GigE, PCIe 2.0 5GT/s] [15b3:6750] (rev b0)
05:00.0 InfiniBand [0c06]: Mellanox Technologies MT26428 [ConnectX VPI PCIe 2.0 5GT/s - IB QDR / 10GigE] [15b3:673c] (rev b0)
84:00.0 Ethernet controller [0200]: NetEffect NE020 10Gb Accelerated Ethernet Adapter (iWARP RNIC) [1678:0100] (rev 05)
85:00.0 Ethernet controller [0200]: Chelsio Communications Inc T310 10GbE Single Port Adapter [1425:0030]
86:00.0 InfiniBand [0c06]: Mellanox Technologies MT25204 [InfiniHost III Lx HCA] [15b3:6274] (rev 20)

(I do have a couple of open slots if you have some RDMA cards that I’m missing to complete my collection :))

    I would so love for you to take a look at bufferbloat issues in that gear….

    • roland says:

      I know bufferbloat is the trendy thing to talk about these days, but do you really think it’s an issue on networks with single-digit-microsecond latencies and 10s of Gb/sec of bandwidth?

  2. Dave Täht says:

    How it interacts with other networks with 10s of ms latencies is the problem. ECN and SACK are not widely tested, and RED and other AQMs are buggy.
