Access "ATA over Ethernet for converged data center networks? No way"
This article is part of the November 2010 Vol. 1, No. 1 issue of Building the infrastructure to enable flat Data Center network architecture
By Ivan Pepelnjak, Fast Packet Blogger When I started exploring storage networking technologies from a networking engineer's perspective, I stumbled across ATA over Ethernet (ATAoE) – or ATA command set transported directly within Ethernet frames. The approach seemed similar to Fibre Channel over Ethernet (FCoE) – only with even less industry acceptance. As I abhor protocol designers who are shortsighted enough to purposely limit themselves to a single LAN domain, I never looked deeper into the technology until I stumbled across an article in The Register praising the virtues of ATAoE. Check out Ivan's blog: Cisco IOSHints Long distance vMotion and the traffic trombone vMotion: An elephant in the data center room DCB and TRILL have nothing in common Further research quickly confirmed that ATAoE is limited primarily to a single vendor (Coraid) and the Wikipedia article on ATAoE revealed an "amazing" fact: "AoE specification is 12 pages compared with iSCSI's 257 pages." While I never considered the length of protocol specification to be an indication of its ... Access >>>

ATA over Ethernet for converged data center networks? No way
ATA over Ethernet is pitched as a solution for converged data center networks, but ATAoE has a host of technology shortcomings, including a lack of packet loss recovery and shaky security, according to Fast Packet blogger Ivan Pepelnjak. So why bother?
