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? -Grant ----- Original Message -----=20 From: mojo fms=20 To: Grant Peel=20 Cc: freebsd-questions@freebsd.org=20 Sent: Monday, July 20, 2009 4:21 PM Subject: Re: NFS- SAN - FreeBSD 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.

Obviously, to store all users /home data. = Throug an NFS connection via fast (100m/b) ethernet. Each connecting = server (6) contain about 200 domains? -Grant ----- Original Message ----- From: "Grant Peel" = To: Sent: Saturday, July 18, 2009 10:35 AM Subject: NFS- SAN - FreeBSD=20 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)?
