Hi guys,
I have a question that is real important for me; How can I connect my two sites so that I am able to use RDMA between them?
I have 2 racks, each located in a different datacenter. Each rack has got its own SX1036 Ethernet switch, and all servers are connected using connectx-3 EN or VPI PRO adapters. The server-switch cabling is all in the same rack, so these cables are passive. The time has come to connect my the sites together, so I will be needing active fiber between the sites.
I have the following options to choose from, please note that I am fairly low on budget, so buying a metro-x long haul switch is out of the question.
I can rent a fiber-ring, giving me 2 Darkfibers, or either go with a 10gbe L2 or L3 ring.
Lets say I take the fiber-ring, can I just buy 4 QSFP+ LR 10km tranceivers and install these into my SX1036's, connect both darkfibers to both switches and I'm good to go?
I really hope someone can explain how to tackle this problem without losing RDMA capability between the servers.
Thanks,
