Interesting design but I doubt that you can get much performance out of this when you take a look on the backplanes. Assigning one S-ATA cable to five ports cuts down the bandwith. It's different to "traditional" backplanes in major server systems which usually have SAS.
True but... If you're using spinning disks it will probably bottleneck at the network anyway. (Unless you're using aggregation) On second thought, $250.00 would get you 16 disks capacity with the POD build. (One card with 4 backplanes). You could get a used LSI 16 port card for less with more bandwidth. I guess this POD design doesn't work out after all.

Greetings XPEers,
I came across a pretty good read this morning and I thought I would share. It's the new design for the BackBlaze storage pod 6.0. It's a 4U device that holds 60 drives using off the shelf components. They use (12) 5 port back planes attached to some extremely inexpensive SATA cards to achieve the 60 drive 480TB beast. This could be scaled down to something a little more realistic. I thought this might get some creative juices flowing. The main article is https://www.backblaze.com/blog/open-sou ... ge-server/
It's a bit long though you can skim to the Storage Pod Parts List here https://f001.backblaze.com/file/Backbla ... s+List.pdf
If anyone does anything with this please leave a comment. I would be curious to hear what others have to say.
Peace and Joy & Bits and Bytes,
Rob

When modern craftsmanship and technology meet it's a beautiful thing. Post the pics and the stats, I'm sure we would all like to see the end result. Have fun!
