Setup ATA over Ethernet (AoE) on Debian 8 (Initiator and Target)
Author: Till Brehm •
Tags: debian, server, storage •
Comments: 1 This tutorial shows you how to setup an AoE client (initiator) and server (target) on Debian 8 /Jessie). The term AoE stands for "ATA over Ethernet" which is a storage area network (SAN) protocol that allows AoE clients to use storage devices on the (remote) AoE server over a normal ethernet network. "Remote" in this case means "inside the same LAN" because AoE is not routable outside a LAN (this is a major difference compared to iSCSI). To the AoE client (initiator), the remote storage looks like a normal, locally-attached hard drive.
