Hi:

I have two questions I'm hoping some kind soul can help me with today.

First, where can I find information on setting up fibre channel served
storage on linux ?  Is there a howto anywhere ?  I've just spent a
fruitless 1/2 hour googling, only to turn up a number of trade mag
articles.  In particular, I'd like to know how to deal with multi-path
setups, and the more entry level the documentation, the better. :-/

(in other words, there are many people here who understand SANs, but I
am not yet one of them)

Second, I'm curious how close to the following setup I can come today:


~  +-- FC Cabinet 1 --+		+-- FC Cabinet 2 --+
~  | some disk        |          | some disk        |
~  +------------------+          +------------------+
~                  |		   |
		   \		  /
~                      SAN FABRIC
		   /		  \
~                   |              |
~  +-- linux box 1 -|-+		+-| linux box N ---+
~  |                | |		| |		   |
~  |        +-------|--cluster sw--|------+	   |
~  |	   |       mirror FC1 & FC2  	 |	   |
~  |	   |          cluster LVM	 |	   |
~  |	   |	      cluster fs	 |	   |
~  |	   +-----/------------------\----+	   |
~  |	        /    |		|    \		   |
~  | user visible fs  |		| user visible fs  |
~  +------------------+		+------------------+

In essense, I wish to have storage across two cabinets, mirrored, sliced
up via a LVM, then served as a cluster filesystem to N linux hosts,
without a single point of failure.

Is the above possible ?  If not, which peices can I not do today ?  How
soon might I be able to do them ?

(Please note that in particular the mirroring need not be done in the
linux boxes, if there's a way to mirror across cabinets in different
data centers in some other manner)

Thanks,
- -- Pat
