Hi,
For a LAN, AOE seems to have less overhead, so performance *might* be better
(assuming the network is the bottleneck).
iSCSI is much more popular in the industry, though.
My experience is with iSCSI - feel free to ask me if you need more info on
setting up iSCSI initiators & targets.
Cheers,

Subject: AOE and iSCSI (software only)
Hello, Linux-il gurus,
I have to decide between two options of exporting block devices
on a LAN (same subnet for clients and server)
: one is with iSCSI target and iSCSI initiator. The second
is with AOE.
I am talking about using software tools only, not using special hardware.
I had tested AOE with my hardware (no special hw): I had downloaded
aoetools from
http://sourceforge.net/projects/aoetools/.
I had also installed blade server of this project on the server
side.
(http://sourceforge.net/project/showfiles.php?group_id=130453&package_id=143
790).
I can mount on the client a file which I am exporting on the AOE
server. (which is running this blade).
My question is this:
What are the advantages and disadvantages of using AOE versus iSCSI?
Does anybody have any experience/advice regarding using AOE on Linux
(sw only, I am not talkin about CORAID, etc) ?
Regards,
Dan

Just to clarify Rony's reply :
AOE protocol is build upon Ethernet layer and so AOE payload is
encapsulated in Ethernet frames
Using iSCSI there 2 encapsutions -
SCSI to IP to ethernet and IP to Ethernet.
So theoretically AOE has less overhead .
