[gentoo-cluster] Like Isilon?

[David Busby]

I'm certian you all know about Isilon, which effectively makes a big huge data location from many dedicated devices.  I 
want to do that too, but on Gentoo.  My vision of the system is like such:

[ 100Mbit Ethernet Corp. Network  ]
  |
  |
[ 2 front end clustered/HA servers ]
   This is what the other network hosts will see, I would like have availablility to these servers via netatalk and 
samba.  I'd make those to boxes to have the same IP with the load balancer in netfilter.  They would serve data from the 
storage cluster behind them.

[ Gig/Fiber ]
  |
  |
[ n+ backend storage servers. ]
   These would be big disk boxes, you know SCSI+RAID5 in the hardware lots of storage space.
   These would run Gentoo as well and then I can add/remove nodes in this storage cluster witout down time or data loss.

I'm looking at evms vs gfs.  Seems like GFS is closer to what I want than evms, but I don't know.
Also, what about when I buy iSCSI devices or some of those other fancy SAN devices, how can I plug those into the data 
servers cluster to use their storage, what package to use?
