Re: [storage-discuss] ATA over Ethernet

I would imagine the argument is that of software drivers
for the storage stack consume much less overhead by
cutting out the IP part - less CPU consumed, perhaps
better throughput. As far as cost, it leverages the NIC
commodity pricing curve without requiring TCP offload.

As a security person one of the things that interests in comparing ATA

provide transport layer security and that seems like a big plus to me.
    

I think the idea of AoE is that you don't have IP, you're not routable,
and you're necessarily on a dedicated network. Frankly, I don't see the
utility over iSCSI.
