October 21, 20232 yr Hello all, Forgive me if I get any of the following terminology wrong, server racks and backplanes are all new to me. I have just bought the following server rack case; https://www.servercase.co.uk/shop/server-cases/rackmount/4u-chassis/4u-server-case-w-24x-35-hot-swappable-satasas-drive-bays-12gbs-hd-minisas-550mm-deep-sc-4324s/ It has a hot swap backplane, with space for 24 HDD's. These are spread over six levels, each with one SFF port. I have transferred my system from my old case to this new one, which includes a Gigabyte Z490 Vision G motherboard. I have purchased two "Mini SAS HD SFF-8643 to 4x SATA 7 Pin Data Raid Reverse" cables, and connected the top two HDD levels to my motherboard, utilising all six SATA ports on the motherboard. Please note, I currently have six HDD's spread over those two levels. Initially I thought six of the above cables, one per level, could be used to allow the connection of 24 HDD's to my motherboards six SATA ports, unfortunately I was wrong. Searching online (Unraid guides) it would appear that I need an SAS HBA card to allow my motherboard to utilise 24 HDD's. Apologies for the long back story, but my question is; is the 9305-24i card the best card for my needs and will it work with unRaid. Understandably, it is an expensive card, with reports of fakes doing the rounds, and so I want to check here prior to any purchase. If anyone has any better suggestions however, I am open to them. Many thanks. Edited October 21, 20232 yr by BeardedNoir
October 22, 20232 yr Since the backplane has no expander to use the 24 disks you need to a have 24 SATA ports, they can be in one or more controllers, a 9305-24i would work for all 24.

Just need to find one at a reasonable price now. 😁 Its my first venture into the server case world and I couldn't be happier, my system is running cooler and everything "just works", should have done this sooner.
