I'm getting ready to put together an updated 24 bay JBOD setup.
I was going to build it with a controller similar to my existing rig:
Computer in the same case with internal sata to backplane using something like the
9305-24i
No sweat.
But then I came across some external 24 bay drive shelves, which are a little more foreign to me.
The first has two SFF-8644 slots, which makes sense to me. Each controls 12 bay and could be run off a single 12G SAS HBA card
like a Dell T93GD
I worry about a bottleneck during partiy, but it might be an option.
The second case has 3 SFF-8088 ports.
What I can't seem to wrap my head around, is there doesn't seem to be anything that can drive 3 8088 ports directly
(ie. some form of 24e card)
I'm guessing there's already some form of port multipler in play on the drive chassis since each channel would drive 8 bays.
What kind of single card would I use to drive 24 drives off 3 channels?
Would I instead be into a 2 card situation (a 16e and an 8e) to drive this or would I run an additional expander off the controller giving me a 3rd port?
I only plan to run spinning disks, but with that many discs I'm mindful of the parity check times.
Being able to use a single card opens the possibily that I could use a SFF PC in conjuction to reduce the power somewhat, but I'm not set on that
