Mac Mini Media Center Project (Part 3)

After I filled up my Mac Mini’s hard drive with my encoded videos from my DVD collection there was not much more I could do till I ordered the Qnap NAS. This would be the most expensive peace of my Media Center setup.

Qnap NAS

After reading about NAS solutions online and talking about it with friends who have experience with such devices I proceded to order a four bay Qnap NAS TS 459 Pro+ Turbo NAS with five, 2 Terabyte Western Digital Caviar Black hard drives. The spare hard drive is incase one of the other harddrives fail.

I ordered both the Qnap NAS and the Western Digital hardrives from Newegg. I have had good experiences ordering products from them in the past and this was no different.

Both the hardrives and the Qnap arrived well packaged on a Friday. It was Martin Luther King weekend and I had all three days to work on this project.

The first thing I did was head to a local Electronics store and picked up this APC Battery Backup, and this Apple Airport Wireless Extreme Base Station. I spent a lot of money on this equipment and I don’t trust it to Juneau’s dirty electricity.

From unboxing everything to final setup only took me an hour. Which was great! I think it speaks volumes on how easy setting up a Qnap NAS. It also left me with a three day weekend to enjoy.

Following the easy to read directions for the Qnap, I took out four of my five harddrives totaling 8 Terabytes worth of storage and inserted them into the Qnap Unit.  I plugged in my APC Battery backup and plugged the Qnap and the Apple Airport into it, then plugged an ethernet cable from the Qnap to the Airport and turned it all on. By default the Qnap wanted to set up it’s self as a RAID 5. The unit supports other RAID options, but I chose to go with it’s suggested default of RAID 5. It took the Qnap maybe twenty minutes to partiton the harddrives and set its self up as a Raid 5 server.

RAID 5 IN A NUT SHELL

RAID 5 means is that event hough I loaded up 8 Terabytes of harddrive storage, I would have 6 Terabytes of usable storage. If I have understood what I have read the data I store on the Qnap is more or less available on two of the harddrives at any one time. The point of this is that one harddrive of the four can fail and I wont necessarily lose any data. Should that happen I would just follow the easy to read directions it came with regarding how to replace the failed hard drive. The Qnap system will rebuild it’s self and all will be right in the world again.

YOU STILL NEED TO DO BACKUPS

Let me stress to anyone who does a project like this or owns a computer in general, please back up your data. I still do backups. Things I keep on the Qnap that I can’t afford to lose, things like photos, home videos, and documents I still back up off of the Qnap on to another hard drive monthly.

With the Qnap up and running I first went into the settings and enabled Time Machine backups. Again, this was a simple process that only took a couple of minutes. Before long every computer in my house (that would be 5) where backing up wirelessly to the Qnap Nas.

Next I went into the settings enabled APC Protection. Should my house lose power for longer then to minutes the Qnap Nas which would be running off the APC battery at this point would shut down after 2 minutes if the power is not restored.

Finally I setup a shares and users accounts on the Qnap NAS. This allows me to store the encoded movies I had on the Mac Mini on the Qnap. After transferring over the movies I was able to start encoding more of them again.

FINAL THOUGHTS ON THE QNAP NAS

At the time of this post I have had the Qnap Nas for a little over three weeks now with no real complaints. I was able to set the whole thing up in under an hour and it’s been very easy to use. I do recommend the Qnap, but also know I have no bases for compression. This is the first NAS I have ever setup.

The Qnap is capable of doing much more then it currently is. I really want to explore the tons of options it has. I do need to compete this first task before I start playing with it more. I have to finish encoding my DVDs first, then I will go back and see what other Qnap options I might like to play with.

I have discovered that the Qnap and iPhoto 11 do not get along well togetherl. This is because of the format of the hardrives in the Qnap. iPhoto 11 requires HFS+ formatted hardrives to run correctly. Qnap does not support that format (yet). My workaround for this has been to use a separate external hardrive for iPhoto 11 which I also backup. I could keep all the photos and iPhoto 11 on my main computer’s harddrive, but I have so many photos  that the space it requires is very large for me. At this point it just makes sense to keep it on a separate external drive.

In my next post I am going to be talking a little bit about file and media organization.

Mac Mini Media Center Project (Part 1)

My TV and DVDs Before Starting the Mac Mini Media Center Project

I own a lot of DVDs. We are talking nearly 500 at last count. It’s sick, I know. Sifting through them all to find the one movie I want to watch has become such a chore that I would rather just fire up my Playstation 3 (PS3) to access my Netflix account and stream something then dig for a DVD of a movie I actually want to watch. So, I have decided that the solution to my conundrum is to setup a Media Center PC. More specifically a Mac Mini media center attached to my T.V. with an interface that even my mother could use.

WHAT DO I WANT THE END RESULT TO BE?

  • An uncluttered home theater.
  • A small computer hooked up to my T.V.
  • Access to all my media and the internet.
  • The ability to back up all my computers
  • A new storage solution for my physical media.
  • An interface so easy my mother can use it.

RESEARCH

Like any project you should do research into it first. Which is what I did. With google as my guide I sought out other peoples experience with setting up a Mac Media Center. Here are a list of some sites I found that where helpful to me.

I also spoke with friends of mine who had done similar projects. It always helps to read, write, and talk to people about ideas you have. It helps flush out the details of what is trying to be accomplish.

All of these sites listed above where very helpful to me, but none where setup quite the way I wanted. Most of these talked about just using the Mac Mini or the Mac Mini with an external hard drive attached and honestly that probably is the solution for 90% of you out there. But I was looking for a setup with a little bit more free hard drive space for me to use. Particularly because I have several computers in my house and I want them all to be able to back up wirelessly to on location. I also enjoy editing home movies and having a place to store the massive video files I work with is important to me. I think I have come up with a solution that works as you will see.

LOGISTICS

One pressing question I had from the get go is; How much hard drive space am I going to need? 500 DVDs is a lot of movies and T.V. shows. So how can I get an idea of how much hard drive space I am going to need?

Most people building a Media Center PC are doing so to encode their DVDs onto a hard drive. If you where just to copy the DVD over to your hard drive your looking at something that takes up anywhere from 2 to 8 gigs of hard drive space. When you encode a DVD onto your hard drive you have the option of removing all the special features, menus, audio commentary, subtitles, and non-english audio tracks leaving you with just the movie. What this means is no more waiting through previews, FBI Warnings or other types of bullshit that is preventing you from watching the movie you want to watch. You just get the movie and your left with a much more manageable file size.

Handbrake Application Icon

One free peace of software I read about and that everyone pretty much agreed is the best DVD encoding tool is called HandBrake. Before dropping a single penny on my media center I could preform tests to make sure the video is going to look great and be a manageable file size. I downloaded Handbrake and picked a DVD off my shelf at random and encoded it. Using only HandBrake’s presets I found that encoding under the “High Profile” preset rendered out a 1.5 GB file. Playback of the DVD and the encoded movie showed hardly any noticeable difference. It certainly looked a lot better then any Netflix movie I had streamed in the past. If I take the 1.5 GB as an average and multiply that by 500 (the number of DVDs I own) The end result is 750 GB. A very manageable figure.

It’s a very manageable figure till you miss calculate TV shows like I did.

At the time of this post I have encoded several movies and TV shows using Handbrake. Something I over looked is that the average movie is anywhere from 1 and a half to 2 hours, give or take per DVD. Now lets take E.R. on DVD. The DVD for E.R. holds 4 episodes at about 1 hour each. You have 24 episodes a season and that is roughly 24 hours of video which ends up being a little under 1 gig an episode. It adds up! It was something I over looked when I did my initial estimation of how much hard drive space I would need. Don’t let that catch you off guard like it did me. Do the math right so you know how much hard drive space you are going to need to hold your DVD collection.

Open Source Quote

This quote was found on the first post of this Zenoss forum. It was written by user ‘bithajcsar’.

Open source in general, is only for those, who do not have any serious responsibility.

Now, I do feel that I should express that I love the idea of Open Source, and I think very highly of enthusiastic open source programers. But, their is a reason why open source is not as widely used.

SLAX

Everyday it seems I am learning something new at work. For me this is fun since I get to work with computers all and I enjoy it. So anything new I learn about computers and software, and how they work is a bonus .

Recently I learned about a Linux Live CD called SLAX. A Live CD, as I understand it is any computer operating system that can be run from a CD-ROM. This can be very helpful if you find your self with a computer that has a bad hard drive. You can still use the computer from the CD-ROM. Just put in the Live CD and tell the computer to boot off the CD-ROM from the Bios.

The resin I’m sitting here tell you about SLAX over other Live CDs I have found is because SLAX is very fast. It’s actually useable. When your running an operating system from the CD-ROM you want all the speed you can get. Other live CDs I have used have been very slow and laggy. That has not been the case for me with SLAX.

You can download a copy of SLAX from http://slax.linux-live.org/.

You can customize your copy of SLAX with a tool called “Myslax” that is located at http://myslax.bonsonno.org/

You can visit a great fan site on Slax here http://www.geocities.com/slaxfansite/
