Or for a low-tech solution, if the disks are identical, boot rescue
mode from CD and

dd if=/dev/sda of=/dev/sdb

Where sda is the whole disk of an already installed system and sdb is
a blank disk.

If they're HP Proliants or similar you can use their hot-swap
mirroring to mirror disks even quicker than dd.
