EMS "Alpha Rack"

One of the reasons I decided to build a Backblaze inspired Extreme Media Server was that I wanted to replace 4 of my custom built "mini-EMSs" (see pictures below).

With my new full sized Backblzed Inspired EMS, I'll be able to replace these 4 mini-EMSs you see below.

Please don't give me too much grief on the messy nature of this particular install - as I'm sure some can appreciate, this is definitely a constant work in progress. More a R&D type lab than a finished install :).

By the way, these mini-EMS(s) were actually built using the same basic idea of the Backblaze boxes. The main difference was that I used straight SATA backplanes which were then connected into a Port Multiplier "External" Card/Board that then finally went into the Silicon Image Controllers. While this definitely created a cabling nightmare, the solution worked and worked well.

One of the items I like with the old solution is having removable drive bays...








For those curious, the orange cables are fiber optic cables feeding the HDMI runs/extensions to various TVs in the house. The laptop above the mini-EMSs is used as a poor man's lighting controller for various items in the home. The rest, is pretty much just a fire hazard!

  2. Matthew -

    I use a program called DVD Profiler from Invelos to manage my DVD/Video Collection. This program works great, but wasn't intended for virtualization/media servers. However, it does allow for plug-ins and I wrote a custom plug-in for it that extends it core features very nicely.

    I essentially put everything into DVD Profiler, my plug-in then effectively duplicates this information to a back-end SQL database which I tap using an IIS/ASP program from the Media PC to play my various movies with a remote control, etc.

    You may wonder why I don't just tap into the DVD Profiler DB directly. The main reason is that the DB archecture in DVD Profiler is a bit of a nightmare - for me at least. Some form of DBISAM that after playing around with for a few weeks just didn't seem worth it. While I'd like everything in one DB, Invelos is nice enough to expose the high-level data via APIs and it is easier than reverse engineering a DB that I'm not familar with or have the tools for, etc.

    For a one-up custom solution, if I say so myself, it does work fairly well although it is a bit rough around the edges.

    I also played around with XBMC for awhile. Did a very nice job but was going to require that I rename a lot of my files and re-code some areas that didn't work for me. Since I already had a good solution in place I wasn't willing to switch. However, if I was to start from scratch, I would seriously look at using this software instead - especially now that media sources for most folks are coming via online sources instead of DVD/disc Packages.

  3. Love it! Came across your blog from the BackBlaze blog... been drooling over their pod design for a while. I will enjoy reading what you've done with it as I embark on my own journey...

  4. What kind of enclosure/case are you using for the four servers?

  5. >> What kind of enclosure/case are you using for the four servers?

    These were Lian Li PC-A17 Cases. Basically 9 - 5 1/4" bays. I then took 3 of the bays and used Adaptec 5 Drive Modular Bays to get me 15 drives per system, etc.

    Here's a link to the case - not sure if it is still current though:

    What interfaces are available to convert and extend hdmi over fibre?

  9. I found the fiber device interfaces mentioned in your other posts...

  10. As for the fiber extenders, you might also want to take a look at their CAT5/6 extenders as well. Apparently the latest units are much better than the ones I initially tried. If they work as advertised, it will save you a ton of money over the fiber.
