Thanks for the reply.
I have not used/investigated the iSCSI thing yet....
The original question is can I just use an NFS mount to the storage's /home
partition?

You would be better off at least having the SAN on 1gb ethernet or even
better tripple 1gb (on a 100mb switch should be fine but you need failover for
higher avaliability) ethernet for latency and failover reasons with a hot
backup on the network controller. I dont see why you could not do this, its
just iscsi connection normally so there is not a big issue getting freebsd to
connect to it. We run 2 of the 16tb powervault which does pretty well for
storage, one runs everything and the other is a replicated offsite backup.
Performance wise, it really depends on how many servers you have pulling data
from the SAN and how hard the IO works on the current servers. If you have 100
servers you might push the IO a bit but but it should be fine if your not
serving more than 2Mb/s out to everyone, the servers and disks are going to
cache a fair amount of always used data.

Hi all,
I am assuming by the lack of response, my question to too long winded, let
me re-phrase:
What kind of performance might I expect if I load FreeBSD 7.2 on a 24 disk,
Dell PowerVault when its only mission is to serve as a local area storage unit
(/home). Obviously, to store all users /home data. Throug an NFS connection via
fast (100m/b) ethernet. Each connecting server (6) contain about 200 domains?

Subject: NFS- SAN - FreeBSD
Hi all,
Up to this point, all of our servers are standalone, i.e. all services
and software required are installed on each local server.
Apache, Exim, vm-pop3d, Mysql, etc etc.
Each local server is connected to the Inet via a VLAN (WAN), to our
colo's switch.
Each server contains about 300 domains, each domain has its own IP.
Each sever is also connected to a VLAN (LAN) via the same (Dell 48 Port
managed switch).
We have been considering consolidating all users data from each server to
a central (local), storage unit.
While I do have active nfs's running (for backups etc), on the LAN only,
I have never attempted to create 1 mass storage unit.
So I suppose the questions are:
1) Is there any specific hardware that anyone might reccommend? I want to
stick with FreeBSD as the OS as I am quite comfortable admining it,
2) Would anyone reccomend NOT using FreeBSD? Why?
3) Assuming I am using FreeBSD as the storage systems OS, could NFS
simply be used?
4) Considering out whole Inet traffic runs about 2 Mb/s, is there any
reason the port to the Storage unit should be more than 100 M/b (would it be
imparative to use 1 G/b transfer)?
TIA,
-Grant
