Anyone here use NAS (Network Accessible Storage) devices?
lilshawn:
Wd red drives which are made for nas use are only about $20 more than equivalent blue drives.
MonMotha:
Yes, the WD Red drives are one of your best value options in this particular case. They seem to work well, have the features you want in this application, and are of reasonable cost.
lilshawn:
freenas has some power options built in to power down drives that aren't being used after a period of inactivity. every minute an HD spends not turning, is a minute longer it will last at the end of it's life.
if you can stand the couple of second delay of spinning up the disks, that's an option too.
lilshawn:
well, i've ran into my first hitch.
the NAS dropped off the network last night. Was reading videos off it from 2 XBMC xboxes at the same time. they both came up and said the host was unreachable after about 3 hours or so. I just reloaded the videos of my desktop share to diagnose the issue no problems there... For the time being i've left it (crashed or otherwise).
i tried to ping the ip address from my desktop of it and wasn't able to reach it. I searched the network logs on my firewall to see if it had picked up a different IP address or something...didn't see anything new. did a few quick searches about the network drop issue and found a few people with multi port NICs that had issues, but one thing i did find was I think i might be a bit skinny on the RAM.
4gb seems to be the consensus for the minimum needed when you use the ZFS file system. (which i used to stripe the drives together.) having only 2gb of ram might be getting full with checksumming data, data, logging, read cache etc etc etc... so it seems this is the most plausible answer. info Ive found says ZFS typically requires a minimum of 8GB of RAM in order to provide good performance. The more RAM, the better the performance...a general rule of thumb is 1GB of RAM for every 1TB of storage.
I grabbed another 2gb to throw in there to see. (i left it as it was until i figure out the issue.) if it's just crashed then I'll reboot it and test it again with the 2gb and see if it happens again. if it crashes again i'll try with the extra RAM. if still...maybe an installation or configuration issue. Though i didn't stray too far from the standard installation. Hopefully 4gb of ram is good enough for my 1tb of storage. if not, i may have to rethink my file system used or the hardware i've chosen.

The way Freenas works, you want 4 or more memory wise. It's highly inefficient in it's processes compared to streamlined systems. Freenas is fun for a while, but quickly you'll come to the consensus most of us have about it, which is it's not really worth the hassle and poor performance.
