Posted a lot of photos on Discord again today ...
These NAS motherboards passed CPU Stress testing and moving ahead now + a lot of other stuff ...
Under RAID Rebuild // Typical HDD load these consume ~167W
Interesting, power savings are very minimal from our original Dell DCS6100 cloud node configs (now ~16 years old); 2U Case; 3x Opteron 2419EE 6C 1.8Ghz 48G DDR2 ECC, with 4x 3.5" HDD each consumed 180-185W
We still have some of those in production for Seedbox on the very old Value250 / Super250, Super1000, M1000 series.
Intel N100 offers better CPU perf, more RAM throughput as well, and the 2.5G Uplinks.
Delay on the delivery of N100 NAS offers is on the software side. All hardware done and validated too. We'll get there, no worries.
(ofc, design is never done; Need to get some custom SATA backplanes designed and built ... know a good electronics designer who'll do us the full assy so we can order from say PCBWay preassembled? Let us know!
Essentially, built in DC buck converters + sata passthrough to get sanity back from this level of cable management)
New Kerava DC internet is up, and it's now mostly software hurdles (like this NAS) to get production ramped up!
Everything on that front is coming up together nicely, it's been a long journey and maybe i should do some write up(s) in our blog once we hit production.
Software is just man hours, all the major unknowns have POC done a long time ago, rest is just same ol' same ol' crunching code and testing.
Thanks to everyone supporting us on this journey!

i pulled my cancellation request because i want to see how this pans out
we can deliver now, manually installed without almost any remote management. Just letting you know if you don't want to wait for reinstalls to work.
That being said, we are very very close to getting the POC level working and done. Just need some gateway minipcs, etc. basic stuff and a few hours of coding and installing minimal distros for installation system.
Our rescue system will probably be built on top of Finnix -- just need to add more packages and our scripts to it. Grml is another potential choice, and would be more idempotent and trackable for changes, but Finnix seems to be faster to get running with.
Templating truly is this dead simple; https://github.com/MagnaCapax/mcxSauces/blob/main/baremetal/mdSeries/cloneLiveSystem.sh
We've been using that hard coded version for the 2xUSB booting of 4+TB in BIOS legacy/CSM mode (bios bug; The normal just have GPT + UEFI partitioning stuff don't work on these ...) for 2 years now ... Damn time flies!
The first N100 NAS units has been online and up on SystemRescue live system all this time, seems to be stable, and been conducting some thermal design tests on them. Found means to enhance cooling.
These are total PITA to assemble right now, but we will find a way!
If anyone knows suitable SATA backplanes with 12V to 5V converters included for us, there's a reward. (or we'll just get a electrical engineer to design custom ones perhaps)
not 12V, but might be of some use:

Or, you can get any back-plane from a HP or DELL, all of them have only 12V input power ( and have de 5V converter incorporated ) - as I recall and remember
https://www.ebay.com/itm/186098812536?_skw=HP+12+bay+conversion&epid=2315889684&itmmeta=01K1V1DCFH3GEV7ZVVV56C2TJV&hash=item2b545a8678:g:gEcAAOSwwy1moPlB&itmprp=enc:AQAKAAAA0FkggFvd1GGDu0w3yXCmi1dn7GIZC94E9jXqqvjPZTXh0XZ5ddEzq+FpeuAiFnRl0v1O+sfn742lREdAemoW+oDb3TMCsyN+5pZFj7TrZHFQ+Vo1OhGFbGN+2bJcME/h96JoWAJLwHNXNw5nuqB2+2KI174DqI9Eh3UtbGhAt8APl2kk0Qxsc0h6kne5jOP/DTzM8C0JBj8Xp6iyadN1ldGXrsLbLcnLaUNAbJmcYCh+mxbng0FXoTYCV0z5gooUmBdNlzh80i71evMSIn6phYk=|tkp:Bk9SR4rIteGOZg
Or, you could use a Shelf, power it 220v and use a break pout cable from SFF-8644 to 4 Port SATA - tho, you will use only 8 drives out of a 12 bay system this way.
I would go for the first option, and just power them externally with 5V and 12V . Those shelves ave 3 connectors on the back-plane also, 3x4 drives each.
Hope I understood and helped your question
Cheers!
Found HP 775402-001
But not certain if these actually have buck converters (both Grok4 and O3 claims so!) -- regardless, will make it easier at least to have converters next to PSU probably.
Not true, not all of them. Infact, seems rare. But i'll try the one suggested, and maybe some Dell variant as well.
Bought already 2 variants from HP. I'll check some Dell too.
We also need them 1U sized. We made the platform ourselves, previous pages show some photos.
Bought: https://www.ebay.com/itm/335715104164
Total of 43 units ... once they arrive via sea freight in a few months.
In the meantime, we'll do these abonominations of wire chaos.
Got it, you need 4 bay ones, yes, toes usually do not have a DC to DC converter on them, the 12 bays have, as I only saw Yellow and Black on the power plug colors.
SRY, but 4 bay models are not my thing
Happy you found a way!!
I can also recommend some 12V to 5V step down converters that actually work, and are cheap, I use them in Car Automotive.
They are from CPT

Typical SSD will drain ~1.2-1.5A at 5V max, so I would go for the 10A model.
Ah, i tend to use directly the chips and choose the voltage from potentiometer. LM2596 and XL4015 etc.
Got these for current SATA power; https://www.aliexpress.com/item/1005007260232987.html
If i recall right those have XL4015 chips in them, enough with huge margin for 2 drives each on spin up.
Our volume is high enough to justify build in house costs tho, but it all takes time. It'll quickly be an year before the product is ready.
Really late to this thread, but love that your custom making all your mountings. This looks like it'd be a lot of fun to work on!
Goal is to make it boring tho ... when it's boring it means we are mass producing them
Progress Update;
It all is coming together slowly. Step by step.
The backplanes ordered probably will not function, as we wanted power control on the drives per node as well. We will see. Meanwhile the few of these we will MFG has to be done through brute force (put man hours into it).
We'll just have to get one designed and made ourselves once we've consumed this batch.
So many nodes pending for first proof of concept level of our automation, but it will take at the very minimum like 3-4 weeks more, if not months. So many parallel tasks running. Really did not expect to hit this bottleneck quite yet.
Can you please check the status of service how long will it take to get reflected in client area. Still is in pending state. Below is my invoice:
Invoice #211363
I see you made a bunch of tickets, flooded replies on all tickets, message here, DM etc. ALL of this within the past 12 hours.
You have been refunded, and billing profile closed. Please do not come back. We don't want staff to be harassed like this.
MD series servers have target of 2 business day delivery, not few hours or instant. You demanded also distro we don't offer.
Please do not approach us again. Even during writing this i see yet another new message from you. We are not your chat partners nor therapists.
First production design rack is filling right now, got online yesterday and should shortly be in production -- this is where we test and the build automation on. Yes, we are doing rack scale designs now to streamline production.
Having meetings to find partners for design and production to scale things up, now that designs are about finalized and it's time to do polish, and design and manufacture the accessories (ie. custom rack rail kits, commercial ones are too expensive. Or One way HVAC valves, intake vents etc.)
12x3.5" HDD production versions will take time beyond these few proof of concept builds.
We way underestimated the work it would get to do all the software for provisioning, design hardware, design DC etc.
So things take time. We have finally some progress on POC code as FOSS;
The last two might be completely reworked and refactored out, but we shall see as we start to put things together and integrate.
Any step for provisioning which is more difficult to attain has already been POC level tested. It's now about forming the architecture, and doing the heavy lifting for code.
No idea of ETA etc. and what are the final forms, but the plan is that as much as we can will be released as FOSS.
This hardware design is too complex for us to mass produce right now. It takes too much human labor.
Works as a few prototypes sure thing, but takes way too much effort. Many many times the effort to build one of these compared to one of the 8x MD models. With many more moving parts.
Therefore, we are not yet entering into mass production with these, and are looking ways to simplify. For example, salvaging from existing 1RU 12x3.5" HDD the drive cages, wiring etc. ... then again those usually ship with a full server attached to them .... You can easily see where this is going .... So if we buy those, it's better to put them through their useful remaining lifecycles first for most part i believe.
.... things we have to do.
