Your experience with Fibre Channel must be limited ;-)

Well, some aspects of fibre commoditized. You can certainly get the 1 Gbps
fibre switches for next to nothing. 2 Gbps still holds a premium, but the
smaller port-count 8 and 16 port Brocades are not going to break any
budgets.

I'm starting to see fibre to SATA JBOD cabinets go used under $1K each, but
still haven't seen that happening with RAID.

On a low-utilization server, most people would simply stick in a few SCSI
devices on the server and use a hardware RAID controller. I'm trying to
build additional layers into the system so hardware RAID is done off the
computer and there are no single paths of failure from the adapters, the
fibre networks, or the RAID boxes. None of our applications have more than
10 simultaneous users, so performance really isn't a primary consideration.
And we are not generating $100K of revenue every hour on these things and I
have to cost justify what is basically a convenience and a way to increase
service levels from one nine (99.9%) to two nines (99.99%).

What I want may not exist and that's okay, just checking. :)


Infortrend, Xyratex & Promise (the 3 leading white box RAID manufacturers)
make 12-16 bay, single & dual controller, SAS/SATA-4Gb Fibre Channel RAID
enclosures that integrators (like us) use to make RAID to customer's specs
Nexsan makes a good box but it's a little bit more $$ & I don't think
they have 2Gb, not 4Gb Fibre like most of the others
We even have a line of inexpensive / white box SAS JBOD enclosures
that are used as either expansion boxes for RAIDs or to connect PCI
based boards to
