Share file when USA Linux is not a difficult task, but no doubt the various options may embarrass the administrator's time to make a correct choice.

Some months ago I know the technology AoE (ATA over Ethernet) [1], a lightweight protocol that enabled by loading a kernel module, allows the export of disk drives for the network, available for the other machine on the network. The AoE protocol is an alternative to iSCSI [2] for implementation of NAS / SAN (Network-Attached Storage / Storage Area Network). The AoE has been used by many equipment manufacturers Storage, as well as being an open protocol is simpler to use and provides a lower burden of processing with the same load of traffic when compared to iSCSI, another advantage is that it works in the layer Ethernet, which is isolated (not routable) but passes through switches [3]. It is native in the Linux kernel since version 2.6.11, that is not much investment is needed to use it.

The use of AoE is quite simple in Debian systems can follow the following steps [4]:

1) on the server load the module AOE

  # Modprobe AOE 

2) install the package on the server vblade

  # Aptitude install vblade 

3) export server in the disk / partition desired (details in references)

  # Vbladed 0 1 eth0 / dev/sdb1 

4) the client install package aoetools

  # Aptitude install aoetools 

5) on the client to discover and verify the status of the disks available (exported on the server)

  # AOE-discover 
  # AOE-stat 
       e0.1 5.000GB eth0 up 

6) on the client format and mount the device that is in / dev / etherd / eX.Y, where X and Y is determined at the time of export of the disc

  # Mkfs.ext3 / dev/etherd/e0.1 
  # Mount / dev/etherd/e0.1 / mnt/aeo-disk1 

In fact the technology AoE is very stable and highly recommended for use, I use it soon.
