Network block devices are a way to mount a raw disk volume across a network.  
Think of it as RAID1 but over a network.  They are very useful as a HA 
solution.  There are a couple of them for Linux - the standard kernel has 
shipped with NBD for a long time. (I've never used NBD though).

Probabily the best thing is to point you towards the DRBD pages:
