Want 67 Terabytes of local storage? That’ll be $7,867 but only if you build it yourself. Blackblaze sells online storage, but when setting up their company they found the only economical way was to build their own storage pods. Lucky for us they followed the lead of other companies and decided to share how they built their own storage farm using some custom, some consumer, and some open source components.
Each pod is a standalone HTTPS-connected storage unit with 45 hard drives in it. Nine SATA port expanders connect to 4 SATA controller cards on the mainboard. The system boots from a 46th hard drive into 64-bit debian. Drives are running RAID 6 and using the Journaled File System (JFS). Our first thought when reading this was about the heat generated by those drives. A custom case houses all of this hardware and includes 6 big fans to take care of the cooling.
