Be careful ordering the board. I recently ordered one of the x9 series and found out that if the board was made before a certain hardware revision, being 1.2 with the x9dri it won’t accept the v2 cpus even after a bios update. Now have a pair of 2630 v2s I can’t use even though the supermicro website says it would accept them.

I’ve planned on moving my 2u Unraid setup into a 4u supermicro 846. ive planned on swapping out all the fans for Noctua ones as most people seem to do but am concerned about it being enough cooling. i have an idea but wondered if anyone else has done it?? i plan on removing the fan wall hot swap brackets and drilling out an 80 or 92mm fan spacing and using pwm splitters to double up the fans. So instead of having 3 there will be 6, 3 either side of the wall, blowing in the same direction obviously. I plan to widen the existing holes to 92mm if possible with a dremel and bolt straight through both the fans clamping them to the wall. does anyone think this will cause an issue with not enough cooling??

I have already thought of this and have ordered a spare p420 from eBay and as far as I can tell the virtual disk config is held on the drive not the controller as after a recent card firmware update the configuration from the card was dropped and was able to reimport the foreign config and back running in a few minutes.

Hi there. i assume this is a question that has been asked various times before but I would also guess different hardware will get a different response. i have a dual socket 2011 supermicro server with a flash backed hardware raid card and fully populated with 4tb disks. what I have done is created a handful of 8tb 2 disks stripes and Unraid does detect them as single disks. is there any reason why I couldn’t use these as a solution to achieve better read/write speeds as long as I still keep the dual parity disks there too. i obviously realise that a disk failure will take out both disks on that stripe but with the dual parity would this really be an issue?? i have 12 disks at the moment but soon as I see a decent 24bay chassis come up I will be changing it over and adding more disks. I also plan on a separate controller for the future disks to spread out the bandwidth across a second pci express slot. just looking for some constructive experience. thanks.

I thought as much. Don't think I can give up a sustained 700+ to drop to a single disk read. Thanks for the help.

Hi there. I have toyed with unraid a few times before on old hardware I had lying around but am looking for some advice from more experienced users. So at the moment my main server is a windows 2016 domain server with file shares etc running a 10gb Mellanox card and a 24tb raid6 array on a HP P420i with flash backed cache. All my desktops also having 10gb networking and crucial 1tb NVME drives so I can usually sustain 700-800mb/s to and from the server for average day to day transfers of 20-40gb. Now I understand that unraid isn't going to give the same performance for writing without a couple of SSD's in place but what about read speeds?? Will they also be limited to the speed of the individual disk the data has been written to?? Thanks.

Many thanks. Installed and running.

Yes I already have a couple of AP Pros and an 8 port POE, used to running this on a windows server. I pasted the docker link into my sources on unraid but it doesn't generate a template etc, im assuming this isn't the correct way. My docker experience is limited to so far just installing plex on unraid

Hi there. Im fairly new to unraid. Does anyone have a link to a guide or video that might assist me in installing this?? Thanks.

SO I acquired a new Supermicro dual socket 2011 2u chassis with 12 front bays and a sas expander. I trialled it for a few days with dual 250gb Kingston hyper ssd's that I had lying around, given I know the performance of these drives isn't the best and due to having lots of data to transfer over to the box I decided to remove them and throw in 4x 2tb mechanical sas disks I had lying around and build a raid10. Although the drives are from 2013 i'm impressed with its overall responsiveness and considering long term keeping a 4 drive raid 10 for cache. The issue I have is the mainboard only has 2x sata3 ports and the onboard sas is LSI 2308 so using 4 ssd's is out, so im looking to buy some up to date mechanical drives around 1-2tb and wondered if anyone else is running mechanicals and what speeds you are getting?? Thanks.

I would be tempted to disconnect one of the ports connected to the esata header and directly connect 1 of the problematic drives and attempt another preclear. ive had issues with those cables before, not with unraid but with windows, not saying this is the issue but process of elimination.

I noticed from your listed spec your pre-clears are on esata ports?? Is this still the case??? Have you tried pre-clearing the drives internally??

Ive seen a few of these Supermicro JBOD servers floating around on ebay and am looking to get one to put unraid onto. The manual says the embedded LSI controller will be in IT mode which should be ok and I plan to throw 2 1tb m.2 NVME drives into the x8 pcie slots as a cache drive and a Mellanox x2 10gb card which I already have. Just wondered if anyone has any experience with this chassis or can spot any potential issues running unraid?? Thanks.

12gb Cards are no good as the cables coming off the R510 backplane are right angle and I haven’t been able to find anyone I can get the right cables.

From reading the 9207 generation like the 9211 has the same issues with ssd trim due to the driver used in unraid unless someone can correct me?
