Media server died, starting a plan for a new one

[Tom]

Media box is a go!

It's nice to have it up and working again.

[Melbosa]

hmmm wonder when my synology will be in...

[Tom]

I'm still waiting on the Lian Li case for my nas. Being sent slow boat from LA.

Woo! It arrived today!

The PSU I got for it is just a tad larger than I'd like it to be, so I might swap it out for a smaller one if I have one. Also, This is classic... It's a NAS right? And the SAS card takes SFF8087 cables.. I forgot to order the SFF8087 -> SATA breakout cables. \o/

The darn thing so far is absolutely silent. Too soon to tell how loud it'll be when all 7 HDDs are going in raid 6.

[Mr. Analog]

That's fantastic hah

I'm sure it will do the job, and then some

It is WAY over speced. way. I will have no performance problems with it what so ever.

The nice thing about the case is it had room for 7 3.5" disks, and one 2.5" disk. That was super handy. I was hoping I wouldn't have to just leave the ssd dangling (using my desktop's old 30GB OCZ Vertex as the NASs boot disk). Three of the disks had to mount to a plate on the bottom of the case, but that's fine. It was nice that they made it so they used rubber vibration dampers on those drives. at the very least, those ones will run pretty quiet.

[Thorin]

Yeah, use rubber to stop vibratorsvibrations.

Anyway!  Did you figure out how you're gonna play Minecraft on your big-ass TV yet?

Yeah, after realizing that this nas hw wasnt going to work double duty, I replaced my media box hw as well. It's also way over specced. Core i3 3120, 16GB ram... yeah. it'll be just fine.

[Tom]

Hmm, got my new RAID array online:

The read numbers are absolutely insane. Going to see about the "low" write numbers. But maybe that's normal for a big raid6.

[Lazybones]

The more spindles you have the more speed you should have in your array however writes require more CPU, RAM etc so if you are not using dedicated hardware a software raid might have poor write performance.

[Thorin]

Hey, can you control your media hardware from your harmony remote (or any remote)?

Its a rather beefy machine, it barely notices when the array is in use.

Yup.

This time with a slightly older but custom built kernel: (I disabled desktop preemption, usually gains you some throughput)
