Dear GPFS’ers (or I guess Scalers...), How do P_Keys work with remote clusters? E.g if I have a cluster using the default pkey and a remote cluster with verbsRdmaPkey set can the two communicate without using rdma cm? To take it a step further, what if cluster A has verbsRdmaCm disabled but the remote cluster has it enabled? Do I have any hope of making that work without changing the rdmaCm setting? Trying to secure cross cluster RDMA communication in any reasonable way is making my head hurt... -Aaron -------------- next part -------------- An HTML attachment was scrubbed...
