Hello, Please be gentle with me on this, i'm not as experienced as a lot of you are. I've been testing unraid for about two years now on an old Dell R710. It's been a great experience so i've now taken the plunge to move all my real life data to unraid and use my synology for backups. So what did i buy? Well i have a FD Define 7XL, ASRock x570 Taichi, AMD 5950X, Kingston 2x32GB ECC RAM, H100X AiO, HX1000, GTX1080Ti (Plex transcoding). I have plans to buy two 9201-8i HBA's, but for now i'm planning on connecting 4x8tb hdd and 2x1tb ssd via the mobo sata ports. Ok, now the problem, the mobo has 5 or 6 headers for fans but my setup has 4x120 NF-F12 (120mm @ 3000rpm max) at the front, three NF-F12 at the top (two if which are for the H100X and a single NF-A14 (140mm @ 3000rpm max) at the back. As you can appreciate thats more fans than headers. I have the AIO connected to CPU_fan1 (fan splitter) and CPU_fan2 (pump). That leaves me six fans and four headers. So the question is what would be the best way to connect the remaining fans? Should i buy a fan controller? If so which controller would be best for unraid compatibility? Could i use y fan splitters to connect multiple fans to the mobo? What are the ramifications\risks of such a move and how many can you have on a single port? Appreciating any help i receive. Thanks Also as an afterthought, does anyone have any advice on the best pci configuration for the 1080ti and two 9201-8i cards? I suspect the gpu should go in pcie slot 1 and the remaining cards in the remaining slots? Would just like someone to confirm i'm doing the right thing there.

So the good news is this server is sat on the third floor and has a UPS so very little worry on that front. However i get your point on user error. Thats why i use duplicati to backup the data to my synology.

Would you like to elaborate on the much more probable problems? Any knowledge is always welcome.

Thank you, I apologize, I didn't mean to rant, I was incredibly frustrated with the lack of simple yes no questions which result is yes or no to ECC ram, eg is your data critical, is stability an important factor etc. Don't get me wrong, I still have a lot of reading to do but certainly from a number of YouTube videos, forum posts etc. there is no hard answer (exactly what you said) which I find really surprising because I don't consider computers an art form, but a science, so surely there's a logic diagram which helps you reach this decision. Anyway.... OK, so with regards to backups, if you're backing up a file which suffered bit rot, your backup would be compromised too over a period of time. You wouldn't know you were suffering bit rot until you accessed the file. The question then becomes how do you identify the early onset of bit rot on a file and restore it from healthy backup? Lastly by my definition, the data is not critical, however I'm sure my partner would disagree as it contains a whole bunch of home pictures and videos. Based on that i need to take the appropriate actions to ensure the data is protected. With this in mind, I can take a local backup to a local NAS (my old one pre UNRAID), but I was also looking at using CrashPlan via docker as an offsite backup, but I'm still concerned about the horror stories I've read relating to bit rot. Your thoughts and guidance would be appreciated.

@Lolight My objective was a better understanding, you presume I had any preexisting knowledge. In your example, knowing what auto insurance or roadside assistance is in relation to a car when all i know is a car exists (it has four wheels and moves and turns and requires fuel), but noone has taken the time to explain i require at least one of the other items to drive the car. Assuming because someone runs unraid they already have an understanding of all the concepts from disk encryption to docker to gpu passthrough and even to ecc vs non ecc ram is short sighted. However, I thank you for highlighting my shortcomings in this subject and this only inspires me to learn more and try harder so i might help someone else in a similar predicament. Lastly i wish you an awesome day. @FlyingTexan thanks for your support, it really is appreciated. I have found this thread which helps provide some insight, and this comment seems to be the one which helps the most on my initial understanding (i still have a lot to understand in this space before i pull the trigger on my purchase, but i'm currently considering a 5950x, x570 taichi, two sticks of ksm26ed8/32me as the core of the new build): Thanks again both of you

I have an old enterprise grade server (Dell R710), but i'd like to upgrade it as its running DD3 RAM, SATA 2 etc. I want to move from rack mounted to a tower (thinking Define 7 XL as it will provide space for additional drives). I currently have 4HDD's and 2 SSD's plus the usual USB stick. I've been doing some research but can't seem to find definitive answers on the following: 1. Does ECC RAM really help that much, or is it a gimic? I suspect the former. 2. It seems some mobo's unofficially support ECC memory (asus strix + amd) and mention it is subject to CPU, should i steer clear of this unsupported configuration? 3. Does anyone have any recommendations (based on the below performance information) on CPU/RAM/Mobo combinations which are known to work and would fit correctly in a tower without modification. 4. Any recommendations on a good HBA? Additional notes: I plan to install a 1080ti , 2080ti and an additional 4 hdds. Workloads: 32 docker containers 1 windows 10 vm (2080ti will passthrough) Would also like to achieve 4k transcoding for plex (1080ti) Current performance: 2 x x5660 = low 2% average 13% max 79% 72 GB DDR3 = average 19% max 56% Any questions let me know. Thanks in advance for any help.

Hey, Did you complete this build? I'm curious about your experience with ECC support for that board and cpu. Thanks

Did you manage to resolve this?

Its strange because some APC units will report it wile using the specific APC software, but trying to get it to report the information to unraid is almost like voodoo. I've hear reports that if you want a floor or desk standing unit, CyberPower smart units are the way to go, but if you want rack mounted, APC is the way to go. There doesn't seem to be an up to date hardware list in terms of support anywhere, all of it seems to be very old. I have started looking and i'm currently deep diving into one of these: https://www.apc.com/shop/uk/en/products/APC-Smart-UPS-1500VA-LCD-RM-2U-230V-with-SmartConnect/P-SMT1500RMI2UC They are expensive on the site, but you can get at least a third off if you look around. I'll report back here if i decide on this one and it does whats required. It would be nice if some other people who have UPS's would chime in on their experinces with which ever model they have.

Hello, I recently built out a temporary unraid environment into a Corsair 900D with an i7 4770K and 32GB of RAM. Because the CPU is quite old and was struggling under the load i threw the environment into an old R710 i had from a previous home lab environment and its been working great. I have noticed though that i'm hitting io bottlenecks, as the server only has 6 3.5 drives in it, 2xSSD for cache 4xSata for parity and the array. The bottleneck seems to occur when the cache drives are in use for temporary data and the web console along with dockers become unuseable. I've decided to invest in an upgrade to allow me to throw more disks at the solution. I'm looking at the following ebay item: https://www.ebay.co.uk/itm/Supermicro-SuperChassis-CSE-847-2x-E5-2690-128GB-Ram-36x-Bay-X9DRi-LN4F-Server/362941896837 It seems to have improved processors over the R710 and more efficent processors. Not sure the whole thing is precabled for SAS\SATA and i'm also not sure the RAID card would work with UNRAID. More over i'm thinking about putting a P2000 in there to help with transcoding, but i'm not sure it will fit in the chasis. Any thoughts/guidance would be greatly appreciated.

On thing to think about is the data the UPS reports back, a lot of the information is not automatically reported by all UPS's, eg current UPS load and current UPS load %. I made that mistake and had to live with it for a while now, but my UPS finally died, so i'm now in the market for a new one, but research is slow

Can you tell me what was wrong? I have the same issue.

Hey, I wonder if someone can help here, i have R710 running UNRAID with dockers which seem to intermittently lose connectivty to the network, the symptoms are shown as: 1. Docker containers stop responding to http/https requests I have run a wireshark trace between the server and the client and show nothing eroneous. Does anyone have any thoughts on where i might look or where the issue may reside? I know its something to do with the R710/UNRAID as i was running the same dockers on an ASUS Mobo running Ubuntu with no issues. Thanks in advance.
