    Ceph blustore over RDMA performance gain

    I think SX6036 supports both VPI and Ethernet, so you can have RoCE connection. I'm using an old QLogic 12200 which I think can't do RoCE. With esxi 6.5 there's the same problem: the new drivers has only the _EN variant and I can bring up the network only with a direct connection between the...

    It is not. I'm using a relatively old infiniband switch that supports only pure old style IB, no RoCE. So, I have RMDA communication between the nodes (all the test utilities work perfectly) but not RoCE. If Ceph can communicate only with RoCE this explains all my problems. I was suspecting...

The OSD come up and then mark themselves down because they cannot communicate with each other on different hosts. Can you please share your ceph.conf and/or distribution/kernel version? Is this done with inbox...
