vblade, vbladed - export data via ATA over Ethernet
vblade [ -m mac[,mac...] ] shelf slot netif filename
command starts a process that uses raw sockets to perform ATA
over Ethernet, acting like a virtual EtherDrive (R) blade.
script can be used to daemonize the vblade process, detaching
it from your terminal and sending its output to the system logs.
- This should be the shelf address (major AoE address) of the AoE device to
- This should be the slot address (minor AoE address) of the AoE device to
- The name of the ethernet network interface to use for AoE
- The name of the regular file or block device to export.
- The -b flag takes an argument, the advertised buffer count, specifying the
maximum number of outstanding messages the server can queue for
- The -d flag selects O_DIRECT mode for accessing the underlying block
- 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.
- The -r flag restricts the export of the device to be read-only.
- 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
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.
