Greetings, I have a pair of R2610xis with dual 10Gb controllers, using iSCSI and 7.2K SAS drives, Each VESS is paired with a DataCore SANSympony frontend to provide storage RT mirroring between two sites. Currently, the 10Gb ports on each controller are trunked together to form two portals, both in the same subnet. The VESS and frontend server are connected via a single iscsi initiator/LUN through a 10Gb switch fabric. The idea is to maximize performance and redundancy via multipath between the VESS portals and the frontend server, which also has multiple 10Gb connections. Currently, this setup seems to have trouble maintaining relatively low load (200MB/S, 2-3K IOPS) and gets into high latency issues. I noticed traffic is only flowing through one of the two portals, so I'm looking for guidance on how to isolate this performance bottleneck, properly setup multipath between the VESS and the frontend server, and how to make the most out of this setup?
