nice machine. it is about 1.5 generations behind the current model but
still very capable and has a lot of room for expansion (faster cpus,
more memory, larger disks and lots of 64bit PCI slots).

The PE4400 probably has onboard scsi or you can purchase a simple
U160 controller to connect the internal backplane or an external
storage chassis to.

it works with both 'out of the box'. it will also work with RHEL3 in
the AS/ES/WS flavours.

perhaps. i can't remember but the 4400 might have an on board scsi
you can physically connect to. alternatively you can configure
your hardware raid board to present all the drives a JBOD - i.e
individual drives, which can then be used to configure software raid up.

assuming you're willing to destroy the contents of the drive, sure. when
you create a new HW raid container it will initialize the drives as part
of the container creation.
