[gpfsug-discuss] Joining RDMA over different networks?

[Wahl, Edward]

I believe the new nVidia name for this type of product for IB->Ethernet is “skyway”.      Older types of this will surely get discussed on the list.

I know in the Lustre world that LNET routers are used to provide RDMA over heterogeneous networks.

Is there an equivalent for Storage Scale?
eg if an ESS uses Infiniband to connect directly to Cluster A, could that InfiniBand RDMA fabric be “routed” to ClusterB that has RoCE connecting all its nodes together and hence the filesystem mounted?

ps. The same question would apply to other usually incompatible RDMA networks like Omnipath, Slingshot, Cornelis, … ?
