So, RDMA on Intel, i.e. iWARP, are there actually products that support it? Google leads me to believe that there are 10GbE products that do RDMA, but per Intel, none of their adapters supports it.

Nope; I think they acquired a 10G NIC manufacturer who had cards that did it but it didn't make it into any of the Intel mainline NICs. IIRC Chelsio's the only one still shipping iWARP. In my limited (non iWARP) experience, they were OK? RoCE2 will do most of what iWARP did unless you really don't like Mellanox for some reason.

We got cheap netapp boxes and they're kinda OK? The CPU's murder the write performance but they're otherwise uneventful.

Breaux, Breaux, you seen a defense around here anywhere!?


How much space? What is your budget? What is the workload they're going to be running? What are your feature requirements? What protocols do you need it to support?

The MD3200 is a DAS. The 3200i is the iSCSI model.

I've ran/run a handful of 3200i and 3220i (and now a 3860i) and hell, they are solid cheap bulk storage.

It's connected to a pair of 620's and basically used as a VM storage, pretty light use. I just want to get something that will be under warranty (this one is close to 5 years old) and faster is always a bonus.

Is it possible to get something that can be on the network as well as DAS?

"On the network" as in NAS? Or just shared between VM hosts?

In theory be available for anything to use instead of just the two directly connected servers

How do you want things to access it over the network? What protocols? If it's accessible over the network via, say, iSCSI then it doesn't need to be DAS capable. You can just connect the VM hosts via iSCSI.
