You may well find that the hardware required in each machine to access the
SAN (fibrechannel cards, etc) and switches are way more expensive than
just shoving a cheap hard drive in each machine. Hard drives are
mass-produced, and remarkably cheap for what they do. SAN hardware is
specialist, and expensive.
