I am running a server with a number of GPUs in an open-air mining frame. I have a PCIe HBA connected to six 3.5" SATA drives. The drives are screwed into a pair of drive cages from an old case, but the cages are just sitting on the table behind the HBA card. I realize this is not the best setup, as the drives are getting minimal airflow from the fan I have on the HBA, and my options for when it comes time to add more drives are limited.
I think in most cases the most logical thing to do would be to move to some rackmount enclosure for the drives, but I'm not aware of any rackmount case that could accommodate all my GPUs. I don't think putting just the drives in some kind of rackmount case is an option either, as I don't think the SAS/SATA cables would reach from the HBA on the mining frame to the other case.
Most drive enclosures seem to be built around providing a USB data interface at least, or even a full NAS appliance. Is there such a thing as just a tower of drives that provides cooling, maybe shared power, but allows me to plug in my own separate SATA for each drive?
Or is there some other option I'm not seeing, apart from splitting my single server into separate machines for NAS and AI functions?
