We are in the early planning stages for a high bandwidth interconnect between servers. The software stack will be OFED and GPFS on Linux. GPFS can use RDMA.
The idea is to have two IB switches and each server to connect to both. I've seen such configurations with normal linux bonding (mode=1, active/passive).
- How does this works out if RDMA is used ?
- Is there a possibility to have a active/active configuration at least for RDMA ?
