+### What? ###
+Infiniband requires addresses of end points to be exchanged using an out-of-band channel (like tcp/ip). Glusterfs used a custom protocol over a tcp/ip channel to exchange this address. However, librdmacm provides the same functionality with the advantage of being a standard protocol. This helps if we want to communicate with a non-glusterfs entity (say nfs client with gluster nfs server) over infiniband.
+
+### Dependencies ###
+* [IP over Infiniband](http://pkg-ofed.alioth.debian.org/howto/infiniband-howto-5.html) - The value to *option* **remote-host** in glusterfs transport configuration should be an IPoIB address
+* [rdma cm kernel module](http://pkg-ofed.alioth.debian.org/howto/infiniband-howto-4.html#ss4.4)
+* [user space rdmacm library - librdmacm](https://www.openfabrics.org/downloads/rdmacm)
