I'm currently using a CS380 with x11 6TB HDDs (3.5"), 2 being parity. This is a media server, NAS, etc. My primary goal is to switch to a rackmount case. Ideally, I really don't want a massive 25" deep case. a secondary goal is I really want 100TB of usable storage, whilst retaining dual parity drives. My future plan is switching to 12TB HDDs to achieve this. At the bare minimum, I need 10 drives. Ideally, 11 or more. I need support for a micro ATX board to support an HBA card and a low profile GPU for transcoding. Support for standard size PSUs is a plus. One consideration is switching to a CPU with an iGPU for transcoding, and using mini-ITX with its single slot for the HBA card to open more case options. I also heavily prefer sticking to ATX form factor over proprietary setups.
Current best options I'm seeing are:
Sliger CX3702 - only 10 HDDs, but prefect size. Expensive. 3U. only 100TB usable with single parity.
Rosewill RSV-L4500U - Massive, heavy, 4U. Excellent HDD support (15). Very affordable. Great cooling.
One big question I have; is there a product which is essentially JUST the HDD drive portion of the Sliger CX3702 that would be connected to via an HBA card and a long cable? Having something like a CX3072 with a second bay of drives below it for a 20 drive capacity would be incredible and affordable. I don't want my media server split into 2 separate servers. I'm having a hard time finding a product like this but I'm new to rackmount and pretty sure I just aren't searching the right terms. I couldn't even find Sliger in normal google results but only even discovered the company through reddit comments.
