ATA over Ethernet (AoE) delivers a simple, high performance, low cost
|
||
|
|
alternative to iSCSI and FibreChannel for networked block storage by
|
||
|
|
eliminating the processing overhead of TCP/IP.
|
||
|
|
|
||
|
|
+ ATA-over-Ethernet (AoE) is a thin protocol layer directly on top of
|
||
|
|
Ethernet.
|
||
|
|
|
||
|
|
+ ATA disk commands (ie. read disk sector x, write disk sector y) are
|
||
|
|
put directly into standard Ethernet frames using the AoE protocol.
|
||
|
|
AoE is a block storage protocol.
|
||
|
|
|
||
|
|
+ AoE is a non-routed protocol, therefore does not require IP or TCP
|
||
|
|
protocol layers. This eliminates unnecessary processing and makes
|
||
|
|
network connection to disks simple. It also limits AoE to the local
|
||
|
|
network segment.
