Hi Steven,

Quick question for you-- what are your requirements for high availability? Specifically do you need controller redundancy? If so, how familiar are you with pacemaker/corosync?

I have x86 hardware (old NetApp FAS3020c units) that I would like to load RHEL 6.8 32
bit on and make into "Linux filer heads" that can connect via FCP to NetApp DS14MK4
(and other vendors like EMC) disk shelves then serve out the LUNs via:
FC <--- Really want to get this FCP target working to use with Brocade 4GB silkworm
4100!

ISCSI
CIFS
NFS

The hardware is I think dual Intel Xeon 2.80G/533FSB/512 cache capable and has 4 DIMM
slots and 4 PCI-x slots.  They have a RLM card, Front LCD, and 512m cache/cluster/array
card but I don't hold out a lot of hope of getting them running.  The "HDD" is a
compact flash card slot.  The main board also has 4 2G FC ports, 4 1G Ethernet ports, a
cisco like console port, and even a Adaptec LVD scsi connector for things like tape
drives too.

Do you think this will all work together on a 32bit RHEL/centos 6.8 install?  I have
done a ton of RHEL and RH admin/engineering work but very little development (rolling
RPMs, etc) work so any help appreciated!  I know to look for .spec files to gen RPMs
but nor sure what a spec.in file is.  Looks like a spec file though.  Never really
touched make files so not sure if all these all just goes in one dir and
configure/make/make install will get the RPMs too or not but ultimately I'd like to
learn how to get and maintain an RPM repo for all the files.

I like CEPH but it does not have FC support which isn't good.    I was surprised to
hear FC speeds are now up to 16G and it made me think that FC may be a great way to go/stay
and just re-purpose all the older ($0 resale value due to nightmare licensing)filers,
shelves, etc. BUT use open source SW and do it clean and free license wise!  :)

ANY help GREATLY appreciated!  With luck others can use and build on what I get
working.  :)
