Hi John, Jeff,
My hardware:
Backend: K7/1500, 512M, 3com 905B (100mbit), PVR250 & PVR350
This runs mythbackend slave
Server: P4/2000, 1G, 8139 (100mbit), netgear 802.11b wireless
This runs mythbackend master, mysql, frontend&desktop
Laptop: P4/2000, 512M, netgear 802.11b (USB)
Frontend in the bedroom for evening viewing
Network: DLink 8port 100mbit switch
In this setup, the backend is entirely diskless. It is network booted
and mounts all filesystems from the server over nfs. (Under 60 seconds
from off to recording)
The server has 800G of raid storage for programmes and my DVDs. It is
also my current front-end/desktop machine.
The 802.11b wireless throughput is just about enough to watch recordings
made at upto about 3500kb/sec, but not my usual recordings until they've
been nuvexported.
The eventual goal is to banish the noise of the fans and disks to the
kitchen once I lay network cables around the house. This for me
outweighs the possibility of network troubles losing recordings.
If you do use decide to use nfs, you will need to be sure your PC's can
cope with the network transfers. Not just physical network speed, but
on older PC's you might hit PCI/memory bandwidth limits.
In my case, I needed some fiddling with nfs3 over tcp and the network
buffer memory sizes, but having done that, it works well for me and is
reliable. I have never lost a recording due to a network problem.
I'd recommend you search the net for the NFS-HOWTO and performance
tuning hints and tips.
Cheers,
Mark
