StoreVirtual SplitNetwork - Direct Connection between nodes

[BadHabit]

Hi guys,

I can´t find a clear statement for that in the networking guidelines:

Is it possible (and recommendable) to connect the nodes in a 2-node cluster directly, so without a switch in between by 10GB and use that interface for replication traffic? This could save costs for switching infrastructure and remove a possible failure...is that supported?

ISCSI + Management of course need to go through a switch, but only for storage replication traffic it should be theoretically possible....are there any impacts on Quorum availability?

Thanks in advance

Hi BadHabit,

No, direct connect is not supported. The storage nodes need a switched connection so they can talk full-mesh between each other. The switch(es) also allow multipath, load balancing and failover from the host side. The product is designed to make use of a switched network and will not have full functionality without it.

You may be able to make it work without a switch, but managing any type of failure scenario is a problem.
