September 5, 20232 yr I have a large array, 22 drives totaling 164TB with 2 parity and a 1TB cache. I'm using an HBA card with 4 ports as well as a maxed out SAS expander. Software wise, this array is used for archiving, very little activity. I write data to it once and it's barely ever read back or used. No VM's or docker containers. I've been contemplating swapping out my aging mini-itx motherboard for an ODROID-H3+. https://www.hardkernel.com/shop/odroid-h3-plus/ It's tiny, low energy, has 2.5GB ethernet. Now, how do I get my drives onto it? Well, it has: Quote 1 x M.2 slot (PCIe 3.0 x 4, supports NGFF-2280 cards) A m.2 -> pciex adapter like this: https://ameridroid.com/products/m-2-to-pcie-adapter-straight?variant=32064105578530¤cy=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&srsltid=AfmBOoqFL-28eJ3G9GuP385RA_gXZgmc9IJ0DHV_x8g7WRm4sNpJEMcR3wE The SAS expander doesn't need to be connected to the motherboard, it only needs power + connection to SAS card. I think the main question im left with is will this setup work with so many drives and how much of a performance hit are we talking? Given im either reading or writing to the drive only one at a time and at a very low rate, do you think this is doable? Probably the only problem I can think of is a parity check which will probably take a lot longer but I can live with that.
