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!
