+The vblade is a minimal ATA over Ethernet (AoE) storage target. Its

+(LAN) via the AoE data storage protocol.
+The name, "vblade," is historical: It is a virtual EtherDrive (R)
+blade. The first AoE target hardware sold by Coraid was in a blade
+form factor, ten to a 4-rack-unit chassis.
The seekable file is typically a block device like /dev/md0 but even
regular files will work. Sparse files can be especially convenient.
