Why iSCSI has better speed than AoE. AoE is known for simplicity & no > extra overhead while iSCSI has much features and overhead.
AoE is a network protocol, and vblade is just one program that uses that protocol. I don't think the AoE targets the original poster was testing were designed for high performance. The vblade was designed to be as simple as possible an implementation, in user space, of an AoE target. It's very hard to compare network protocols for storage because it's rare that there's a real apples-to-apples comparison. The AoE target hardware systems sold by CORAID are very fast, and I don't think that anything with a similar price could compete, but if you compare dissimilar things, it's difficult to interpret the results in a meaningful way. It's often more practical to simply try a configuration that fits your needs and then compare it to similar configurations. -- Ed Cashin <ecas...@coraid.com> Find experimental aoe Linux driver patches at http://coraid.typepad.com/aoe_linux_proving_grounds/ ------------------------------------------------------------------------------ This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
