For my home storage systems I've been looking at using Infiniband instead of Ethernet beyond the 1 Gbps link layer (for iSCSI and FCoE LUNs to boot thin clients off of). The cost of Infiniband switches is far lower than Ethernet and comparable 10Gbps cards are a bit cheaper, too. With Ethernet you don't have to think about software compatibility much and since Infiniband is available on enterprise class hardware a lot, you'll get a fair chance at support across OSes too.

- devonkim 12y agoI'm not sure what the actual network topology is supposed to be nor do I really understand their data replication methods across these storage pods, but they can always use an Infiniband to ethernet bridge / gateway and that'd centralize the conversion to the egress side of their switches without mucking up overhead locally. Not like you can stick an F5 load balancer right on top of a Mellanox switch and expect it to be hunky dorey, but there's lots of cheap options to be explored is all I'm saying.
