I’m a bit of a storage enthusiast and I’ve been trying to find a reasonable cheap way of bulk loading 2.5″ disks. I’ve been decided to make a SAS disk tray for 2.5″ disks with vertical disks, along the line of the Backblaze storage pod (here)
I stumbled across some reasonably cheap 2.5″, 24 port backplanes with integrated port multipliers (Supermicro BPN-SAS-216EL1 here) and since they were going for less than $200/ea I got 4 of them.
- Chassis from Protocase compatible with HP rail kits
- HP rail kit
- four or five 24 disk backplanes
- 3x 3-pin chassis fans per backplane
- Redundant power supply
- some form of power management board for managing the power supply
- out of band integration with the SAS expanders on the backplanes
- SFF-8087 to SFF-8088 adaptor plate
- some custom wiring to provide enough 4-pin molex plugs to the backplanes (most P/S don’t have enough)
- 3d printed drive sleds for disks
- 3d printed slots for disks
- 3d printed brackets for fans
Sooo… lots of work to do.
