I thought it might be a good idea to start a general topic about all this server type hardware that is very useful and budget friendly for Chia plotting but is out of the comfort zone for most including myself.
But there are quite a few people here who know their way around this stuff so I;m sure this can get filled up.
I’m just going to start of with some general stuff, hopefully other can expand on that.
JBOD (Just a bunch of disks)
An enclosure that can hold an x number of harddrives, usually including a power supply and a controller with external mini-sas connectors.
HBA (Host Bus Adapter)
An pcie expansion card with internal and/or external connectors for storage solutions.
.e.g. a SAS HBA can have internal/external mini-sas ports to connect to either SAS drives directly or connect to a JBOD.
Mini SAS connectors support 4 lanes, meaning they can split to run 4 drives.
SFF-8088 / 8087
Older generation (SAS 2.0, 6Gbs per lane) Mini SAS connector, 8088 (external) 8087(internal)
SFF-8644 / 8643
Current generation (SAS 3.0 12 Gbs per lane) Mini SAS connector, 8644 (external) 8643 (internal)
SAS connectors are the same as SATA connectors, a Sata drive can also be connected, but a SAS drive cannot be connected to a Sata port
