       vblade, vbladed - export data via ATA over Ethernet


       vblade [ -m mac[,mac...] ] shelf slot netif filename


       The  vblade  command  starts a process that uses raw sockets to perform
       ATA over Ethernet, acting like a virtual EtherDrive (R) blade.

       The vbladed script  can  be  used  to  daemonize  the  vblade  process,
       detaching  it  from  your terminal and sending its output to the system

       shelf  This should be the shelf address (major AoE address) of the  AoE
              device to create.

       slot   This  should  be the slot address (minor AoE address) of the AoE
              device to create.

       netif  The name of the  ethernet  network  interface  to  use  for  AoE

              The name of the regular file or block device to export.

       -b     The  -b  flag  takes  an  argument, the advertised buffer count,
              specifying the maximum number of outstanding messages the server
              can queue for processing.

       -d     The  -d  flag selects O_DIRECT mode for accessing the underlying
              block device.

       -s     The -s flag selects O_SYNC mode  for  accessing  the  underlying
              block  device,  so  all  writes  are  committed  to  disk before
              returning to the client.

       -r     The -r flag restricts the export of the device to be  read-only.

       -m     The  -m  flag  takes  an argument, a comma separated list of MAC
              addresses permitted access to the vblade.  A MAC address can  be
              specified in upper or lower case, with or without colons.


       In this example, the root user on a host named nai exports a file named
       "3TB" to the LAN on eth0 using AoE shelf address 11 and slot address 1.
       The  process runs in the foreground.  Using vbladed would have resulted
       in the process running as a daemon in the background.

              nai:~# vblade 11 1 eth0 /data/3TB


       Users of Jumbo frames should read  the  README  file  distributed  with
       vblade to learn about a workaround for kernel buffering limitations.
