You were completely right. I had to enable the ports as it shares PCIe lanes with one of the PCIe connectors. It's now working as expected and as a bonus I was able to enable virtulisation as I didn't realise that was disabled by default. Thanks.

Here's the diagnostics zip file. Good point to check the BIOS. Unfortunatly I'll need to hook up a monitor to check the BIOS, I'll have to try it once I can get my daughter to sleep. monolith-diagnostics-20210313-1835.zip

I initially had an array of 4x4TB drives (1 for parity) with a 2x1Tb cache pool. I have gradually replaced all of the 4TB drives with 12Tb ones. I would like to use one of the 4TB ones as a dedicated drive for a VM but unRAID doesn’t seem to see it. My motherboard has 8 SATA connections 6 are taken up with the array and cache drives. I plugged two of the 4TB drives into the last two sata ports but they don’t show in the UnRAID interface. Do they need formatting on another machine first?

I'll take you advice on going with intel. It seems that the motherboard options are more plentiful. I found one with 10 sata ports which should be more than I'll need.

I think I've settled on the hardware now, are there any glaring omissions or likely problems I'm missing?

I found a 4U case made by a UK company that looks like it might be a winner XK465F2 4u Rackmount Chassis E-ATX 120mm Fan Wall I'm hoping that with the 120mm fan wall and a reasonable air cooler on the CPU that should be enough to cool a 3700x. It doesn't have hotswappable drive bays but realistically I rarely add or swap drives and a little downtime probably isn't the end of the world. It also doesn't have the SAS connections so I will have to look for a motherboard with more SATA ports.

That's an excellent point! As I'm not specifically constrained for height perhaps a 4U one would make more sense as it would allow for more airflow, a larger CPU cooler, a full ATX PSU and full height PCIe cards. https://www.scan.co.uk/products/4u-short-length-server-case-16x-35-hot-swappable-sata-sas-drive-bays-6gb-s-minisas-2x-525-bays According to the description that case supports 16 SATA/SAS drives. I read about the Dell H200 being a cheap option for up to eight SAS drives, if that is still a good option, can I build the machine with one and add another later?

Hi all, I've been running unRAID on a Dell PowerEdge T110 II since February. We've recently moved house and we'll be having ethernet installed throughout the new place in a couple of months along with several 4k IP cameras. The usual logical cascade happened, so now I want to upgrade and migrate my install to a rackmount case to stash it out of the way with the rest of the network gubbins. Currently have: - 4x 12TB HDD array - 2x 1Tb SSDs as a cache Usage: - The machine is a plex and file server for the house. - In future I'm also interested in running some VMs for dev/hobby projects and possibly a windows VM for Blue Iris. - The rack will be in the garage so noise isn't really an issue but ideally I only want a 600mm deep rack so a smaller chassis will be needed. Budget: around £1000 - I'm keen to overbuild this a bit now so that it can serve us for a long time with space to add storage as required. I was thinking something like a Ryzen 3700x, 32GB RAM and a (low profile) 1050ti. I found a 2U chassis that has 12 hotswappable bays (In-Win IW-RS212-02SC) but I don't know if that's a good choice or not? I'm a bit lost on which motherboard and PSU options as presumably they're different to regular ATX options? Thanks for any help you can give me.

Hi all, I have just made the jump to unRAID from my 2011 Mac Mini with an external USB drive which had been my plex server for the last nine years. I recently started playing with Docker and it was all a bit too much for the poor little Mac. So I picked up a used tower on eBay, threw in a PCI Sata card and some drives and it's currently transfering all my data over. Dell PowerEdge T110 II Intel Xeon E3-1270 V2 @ 3.50GHz 16GB DDR3 1333MHz RAM 2x 1Tb Samsung QVO SSD (cache drives) 4x 4Tb WD White drives (one for parity) Once I've finished copying over all the media and other backups I want to setup Plex, HomeAssistant & MQTT. Plus I'm tempted to look into the letsencrypt container to give myself easier URLs to access the services running in Docker. Also I bought a XFX Radeon HD5450 GPU because apparently there are issues using modern GPUs on these machines due to the way the motherboards were designed. Apparently you can get around it by triming down the PCI connector on a supported card like the HD5450 and replacing the stock PSU with one that has GPU power connectors. I'll see how I get on without any GPU and hope it's not needed but for £15 it seemed like a potentially helpful thing to have in the drawer. I just thought I'd say Hi and thanks for all the posts in the forum, I've been doing a lot of reading over the last week while deciding how to go about this. One thing I learnt the long way was that for the PowerEdge T110 II you have to toggle the Enable UEFI setting under advanced in the unRAID USB Creator and then be sure to set the boot mode to UEFI in the BIOS on the machine. I tried every permutation before I saw the advanced options in the USB creator!
