There are two 1/2-height PCIe slots, so something from NVidia's lineup should be able to fit the bill.

The most popular card for the Microserver is actually the ATI 5450. But pretty much anything that comes with a half-height bracket and isn't too thick will work. I have heard of some people having problems with the 6xxx line that they ended up fixing by cutting off part of the cards heatsink.

After that I think most people just use something like XBMC as the front-end and do it that way.

Edit: The main reason that people prefer the ATI cards for windows setups is that they support audio over hdmi, which is fairly important since the microserver has no built in audio-out.

Damnit, somebody get me a tissue.

My N40L progress:

Installed straight FreeBSD 9 and have been tweaking it over the week. OS (except for /usr/ports, /usr/src, and /usr/obj) are on an 8gb flash drive, and I set up a RAIDZ1 pool across my 4 2TB hdds which ends up amounting to just under 5.5TB. Got NFS setup for serving the goods and I now have sab, sickbeard, and couchpotato v2 up and running, and I just finished setting up ZFSguru to easily monitor the pool FreeNAS style.

Currently getting ~25MB/s transfers from the pool over nfs, with no tweaking. I also haven't looked into Spinpoint F4 firmware stuff. I'll dig into both of those this weekend.

If you're on Windows 7 it's as easy as browsing to the network folder you want to map in Explorer, right clicking on it, and selecting "Map Network Drive." Pick a drive letter, hit finish, and now that folder will come up as your Z: drive or whatever.

If the NAS is running a flavor of Linux, you should be able to install the version they have available on their website, if you have the ability to install the dependencies. I'm currently running CrashPlan on my CentOS 6 file server without issue. Granted, this is a full blown server, not some pre-built unit with a locked down OS, but the same idea applies.

Edit: I'm not sure why I thought it compiles from source, disregard that point.

The specific API for decoding video would be DXVA2, which is all that was supported on Linux for a long time. I run Linux on my Microserver and it also does mdraid so CPU is at a premium on this setup.

I grabbed an nVidia GT520 that came with a half-height bracket for lower idle power use and because there's hardware support for TrueHD audio and so forth. I figure it'll do swell as a back-up video card down the line too if anything better comes out than the Microserver (I kinda doubt I could fit 5 drives + component GPU + PSU + non-embedded CPU in the size / power envelope for years so I suspect this will stand up quite well). For others that don't care or just want a cheaper card, there's an AMD 5450 or anything else lower-end that'll be supported under XBMC on any OS that provides DXVA to it.

evil_bunnY posted:

OS support to accelerate decoding.
It's a combination of everything in the stack - your GPU needs to support certain levels of the hardware decode API, your OS needs to have drivers that enable the API, and your video playback software must be able to leverage the API.

HTPCs are kind of fun to spec out in a sick way because you're always trying to miniaturize everything (bottom-level hardware specs) while maximizing the power to play as much as possible for your needs (top-down requirements).

They've got builds for Windows, Mac, Linux, and Solaris (!) so if Crashplan and ZFS are a serious need for you, you have to go with Solaris and not BSD.

Can't back up a mapped drive.

So from what Fishmanpet said it looks like I can't install the linux version on FreeNAS. Does anyone know any offsite backup solution that will pull directly from my NAS or that I can manually upload to? I'm thinking maybe Amazon S3 until I need more that 5 gigs of space.

You should check out tarsnap. Bit more expensive than vanilla S3 but it is a nice no bullshit solution. I haven't tried using it on FreeNAS yet though.

I'm paying 25 cents a day to keep about 24GB backed up, with a fraction of a cent in bandwidth usage a day.

This is going to sound a little on the crazy side, but if you have the capability to spin up a linux VM, you can map to your stuff via NFS and run Crashplan in the VM to back it up that way.

I think it is possible with some work. I have Crashplan backing up some stuff to my NAS, which is presented as a mapped drive in Windows 7. Don't see any reason why it shouldn't work in reverse - certainly the folders are visible in the 'backup' tree.

This support article was the basis for what I did, based around mapping the shared drive as the SYSTEM user, which allowed the Crashplan service to see it.

I needed to do a couple more things as well before it would work - as well as a scheduled task to map the drive, I also had to stop the Crashplan service from starting automatically, and then set up another scheduled task to do this, with a delay of a few minutes, to ensure the drive is mounted before the backup service starts.

Even if you stop and start the crashplan service subsequently, it will not work if the drive isn't mounted before the service starts on its first attempt after a restart.

This article seems to offer an alternative approach by changing the user that the crashplan service runs as, but I can't speak for it.

A couple of things:

(i) It's normal for the shared drive to show as 'disconnected network drive' in My Computer - it's just disconnected for your user account.

(ii) Occasionally after an update it will stop working and I have to go back into administrative tools and stop the crashplan service from starting automatically as I presume this is flipped back on after installing a newer version.

Apple doesn't cater to people who want to hoard local media - they've been pushing cloud storage and on-demand access for a long time. Plus a user-configurable NAS is the sort of thing is kind of the antithesis of what Apple wants to give their users.

Alright, I split the difference and set it up to run every 3 weeks (it takes about 16 hours to finish a scrub).
Weirdly, the best practices guide for zfs suggests weekly for consumer-grade drives and monthly for datacenter-grade drives. Is there really that big of a difference, or is it just being conservative?

In practice there's very little difference in MTBF and media errors between the two, I think.

This, 10^14 for consumer class drives and 10^15 for enterprise drives. Which works out to around one URE per 12TB on consumer class and 120TB iirc for enterprise class drives.

That's pretty bitching.

The nice thing is though, with PCIe 3.0, with proper lane configurations and PCIe switches, desktops can support all this hardware. You'd have enough lanes for 10GbE NICs, SATA controllers, etc.

If I recall correctly, the current Intel PCIe 10GbE NICs are PCIe 2.0 x4. I'd be hard-pressed to find an empty slot for a 10GbE NIC on a consumer Sandy Bridge based platform. Maybe the CPU x16 bifurcated for two SATA/SAS controllers, and then a PCH x4 for the 10GbE NIC, would support ~16 drives.

Are hard drives fine to be stored for LONG periods of time without power/use?

As in, if I purchase 5 drives. I only want to use 4 in a RAID 5 config but keep the 5th drive as a "hot spare" that just sits on the shelf. Basically having a spare drive ready in case the RAID goes into degraded mode without actually having it in the device setup as a hot spare. Say the array lasted for 2 years but then all of a sudden had a drive failure. Would that drive that's been sitting on the shelf unused for 2 years be just as good as when you bought it?

Put it in an antistatic bag with a desiccant to make sure it's kept dry. I can't see any reason why it would degrade over time.

I have this exact config and so far it hasn't been a problem; I have used the spare drive for other purposes a handful of times to ensure it's not DOA. I don't have enough ports on the controller I'm passing through to my storage VM to have the drive sitting as a hotspare.

Somewhat unrelated, for reasons I still don't know, my trusty old Linux mdraid RAID5 array decided to dump all of the metadata on all but one drive, and md refused to rebuild the array in any meaningful manner. Since RAID is not a backup I have all of the data backed up elsewhere, so I took this as a sign to spin up a Nexenta Community Edition VM and rebuild the array as a RAIDZ2 (I can stand to pare some data off). Currently restoring my data over the internet at about 20Mbps.
