For the money and reliability and expandability (but not power usage),
I'd go with used FC gear.
While this is still on topic, I'd like to point out that FC-AL is simply a framing
protocol. It isn't restricted to framing SCSI, even if this is what 99% of people
use it for.
You can run other comms protocols through your FC-AL network if your HBAs
will support it. One especially neat trick is to run IP over FC-AL. Qlogic
recently released updated firmware for the QLA22xx cards that will support IP
over FC-AL and Sun provides Solaris packages that will enable it.
It is an especially useful trick if you have SBus based Sun systems like the
Ex500 machines (which have FC-AL HBAs built in, and for which it is hard &
expensive to get GigE cards).
Now that 1Gb kit is basically worthless on the secondary markets, you can
set up a fully switched FC-AL network at home for a fairly small investment.
 I bought a Dell 56f switch (a rebranded 16 port Brocade 2800) that was
fully populated with HSSDC & optical GBICs and had a zoning license for
about $600USD the other day. Throw in $50 each for some single-ported PCI
Qlogic HBAs and you're ready to "start cooking with gas".
