according to write protection - see here, if that's your case: https://kb.vmware.com/s/article/1008115 or try another google

i think your command is ok, never used such RDM disks on windows. and yes, no smart info, no spindown, until you RDM a full drive. in one of my unraid servers, i simply create small datastore on ESXI side(physically on SSD), and attach this disk to unraid, and use it as unussigned disk for Docker image. but you can use that way for cache drive too.. if an SSD have good built-in garbage collection, then i see no problems with such approach until you are using your server very heavy with lot on downloads on cache. in such case SSD will exhaust very fast..

you can use esxi RDM to connect hdd connected to mobo port to unRAID. i'm using this way my cache drive without any issues for years.. search a forum, there are several guildes how to do it. one search result from me:

then i would recommend a Mikrotik products, like https://mikrotik.com/product/hap_ac2, much cheaper than your budget. it can do about 1Gbit WAN, have at least 200Mbit Hardware accelerated Ipsec VPN, some wifi - for me i have a cable on all devices that required more than 50Mbit traffic, so not a big deal.. and if you are familiar with Mikrotik ROS, you have so many configuration options..

what are expected total bandwidth? do you need some hardware supported VPN?

if you have an interest, i got it working. some manual work needed, but it just works then.. yes, it looks interesting, but lacks of 2FA authentication, if you wanna make it accessible public. just let me know, i can publish docker settings.

condensed view is working again noticed on different forum..

try re seating all sticks, if that not work, then try identify faulty ones and simply not use them. i would go for larger sticks, 8Gb stick costs about 15EUR, 16GB stick about 25EUR on ebay. see your Mobo manual, i often see that with all RAM Stick populated they work for slower speed. you can go for 4x16GB sticks - 2 per cpu.

if model are the same, it should work.. according to your pic from BIOS - why only 20GB of RAM? one stick missing?

did you tried both cpu's with only one RAM stick with each CPU? and remove all other connected equipment, like PCIe cards, HDDs, .. something weird is going on..

unraid is not about a speed. with parity enabled array even with turbowrite speeds are not near lowest drive speed. i'm using slower drives - less heat, less cooling needed.

for just a test use a single one. 800W is plenty..

Have you some other PSU available, just for a test? simple standard ATX power supply wont work until it have second CPU cable or you have an adapter to switch from GPU cable.

do you have an option to change default page width? i just don't like that page starts on very left side of the screen - i'm using Ubuntu and using side panels that are transparent (see pic. attached). i know, i can modify default css file and can do it with every reboot, so just a suggestion

and i think, you should write a question to Supermicro support. in my experience they are very responsive and answer question about old tech too..

Yes, you can use RAM with CPU only.. so, each CPU sees it's own RAM.

how you populate RAM in slots? have your tried with both CPU and just one RAM stick for each? and without any attached devices..

just for check - do you have all three power cords connected to mobo?

FYI, one of the recent Win10 updates(?) simply disables TLSv1.. we have to apply registry patch to turn them back on as we have app that works no TLSv1 by default..

are you tried long memtest for your RAM?

looks like it's on Invision side? cos i see the same behavior on another forum powered by Invision..

Yours is PCIe 2, 9207-8i is PCIe 3, so more available bandwidth to all connected disks. but it's affected only if you use all disks together like parity check or turbo write.. but you can do step by step - first get expander, and then plan your HBA upgrade if yours is not enough..

@Helmonder provide diagnostics please..

not sure about your card it even have HBA mode.. but according to PCIe 3.0 - if your board have 3.0 slot, the yes, look for 3.0 card. according to link above: RES2SV240 Dual Link on LSI 9207-8i (4800MB/s) gives you 16 x 275MB/s. Plus some ports on your board.

@johnnie.black have a great answers to those questions, so i will link two threads: so all credits to him
