[Gluster-users] Netboot / PXE-Boot from glusterfs?

I am just looking around for a cheap, flexible and redundant
SAN-Solution and started reading about glusterfs.
my network is based on gigabit-ethernet and i have some 16 servers being
connected via infiniband.
After reading some documentation I have a few questions and hopefully
someone could help me with this:
What I need is a SAN/Fileserver Solution that:
- enables (diskless) Linux-Clients to boot over the network (debian,
some "real servers", some virtual ones)
Is this possible with glusterfs? Has anybody tried it? I understand it
is not that easy with a FUSE-filesystem, and there does not seem to be a
out-of-the-box solution, but has anybody tried it, maybe building custom
- i need shared directories for many servers, glusterfs seems to be
perfect for that.
Security is only possible on a per-server-basis, right?
- ideally, i could have a HA iscsi-cluster running on the same servers.
Could I just use the Gluster Storage Platform or would you recommend
setting up my own cluster using debian? I understand i will not have
iscsi with the gluster storage platform.
I'd be happy with a "black-box" like the storage platform, as long as it
is stable, installed in a few minutes and if I won't hit some limits in
a few months that would make me reinstall everything.
I have 2 old fileservers (dual-opterons with 8GB of RAM and a bunch of
SATA-disks, infiniband and GB-Ethernet) that I would use for glusterfs -
at least for now. When I need more performance at a later point, could I
just add two new servers, wait until all data has been synced to them
and then remove the old ones? Does it make sense to leave the old ones
in the cluster? would they slow down the r/w-throughput when my new
servers are faster and have 15000rpm-sas-disks?
