Hello, a few questions on Ceph's current support for Infiniband (A) Can Ceph use Infiniband's native protocol stack, or must it use IP-over-IB? Google finds a couple of entries in the Ceph wiki related to native IB support (see [1], [2]), but none of them seems finished and there is no timeline. [1]: https://wiki.ceph.com/Planning/Blueprints/Emperor/msgr%3A_implement_infiniband_support_via_rsockets [2]: http://wiki.ceph.com/Planning/Blueprints/Giant/Accelio_RDMA_Messenger (B) Can we connect to the same Ceph cluster from Infiniband *and* Ethernet? Some clients do only have Ethernet and will not be upgraded, some others would have QDR Infiniband -- we would like both sets to access the same storage cluster. (C) I found this old thread about Ceph's performance on 10GbE and Infiniband: are the issues reported there still current? http://comments.gmane.org/gmane.comp.file-systems.ceph.devel/6816 Thanks for any hint!
