Its called a SGPIO cable usually used to light up enclosure activity LED's but can be used for other things as well.

@@TekJumble Thank you so much for replying! I have a SFF-8654 to 8x SATA cable. But it also has two of those SGPIO connectors... So I don`t have to do with it anything? Thanks again!

@@tanakaobi SGPIO cable does not need to be connected.

No need, it does not communicate to the cpu or the rest of the system it just expands lanes, pcie slot is only there for power.

Not sure what you are asking me.

It will work with any and all recent sas hba's.

Sweet thanks for confirming. Going to use it for a NAS build with a USFF 1L pc.

@@MetalPhreakAU UUU real nice, its gonna be mega low power when idle.

Soon™, for the past like 4 months i have been working on 2 client projects and have literally 0 free time.

Yup all worked as expected all 16 bays detected properly using a single cable

I do all of it locally, internet speeds are just too low for transferring hundreds of terabytes worth of data.

I farm on a separate machine t630 is just a plotter, i have a single A5000 split between a few VMs and it does the job with little effort on average 6 second partials

It was my dream build for a very long time, finally the time and price of components was right so i sprung into action.

@@TekJumble thats awesome! Definitely subscribing to show support for the project

Its explained in the video, the box doesn't have the expander on its own, it requires all 4 connectors to be plugged in order to access all 16 drives, this allows me to connect just 1 cable and use all 16 drives while also giving me the ability to daisy chain boxes to one another or link one box to multiple hosts.

@@TekJumble Is the overall link speed effected? What HBA are you using?

@@pattygq Case connectors have 6 Gb/s links while the expander that I installed has all 12 Gb/s links (2 of which can be used to connect to HBA) so no there is no bandwidth degradation but that is besides the point because this case will house only HDD's which would not even be able to saturate 1 12Gb/s link. I am using LSI SAS 9300-16E

Thanks man !

What do you mean ?

Its coming, been testing few different distros, finally decided to go with Proxmox due to its flexibility and the ability to quickly switch platforms when needed. I have a few practical tests that I want to do on it.

Thanks, yeah this room is above the basement.

I have had a few days with it now testing different things, this board has some quirks to it, for one re-drivers that are on the board aren't really re-driving all that well out of the box, default values simply do not cut it, I have spent a better part of one day just tunning that and still there is an occasional PCIE signal integrity error also power seams to be an issue, well transient load issue that is especially when GPU's are fluctuating between lower power states to higher power states if you have a constant load then there are no issues but that transient load is a problem, setting a static frequency fixes everything. Other then that it has been pretty smooth build.

At least the GPU's didn't come from the HEN farm this time. But I did re-paste and re-pad all of them just to be sure.

Really got no clue, but I HOPE 250 ish range if not well there is always the next bull run. :D.

@@TekJumble thanks for the answer, you will sell at the price of $250

No, I am in crypto for money but I will probably not sell at 250 that is when I will be thinking of my strategy going forward. I have other ways of earning money and I am not in any sort of rush.

Glad you enjoyed it

When I figure it out myself :D.

Yeah I remove those on all my cables because I tend to break those plastic pull tabs and end up having to pry the connector open in order to pull it out :D

@@TekJumble are you even living if you dont need pliers behind your racks?

@@DigitalSpaceport Exactly 😂 !

These are SAS HBA's. You need two things in order to connect a GPU to your machine, first one being a PCIe adapter/splitter card and the second one being a motherboard that supports bifurcation, if you only want to connect one GPU then you just need PCIe adapter there is no need for bifurcation support on the motherboard. You also have an option to get a PCIe adapter card with a switch chip in that case you also do not need bifurcation support. Note that SAS cables may work with PCIe but its not guaranteed.

My requirements is I have 2 work station with 4 gpu in each, I want to inter connect 2 with sas cable possible?

​@@Prakash_Farmers_Son_Farmer Hmm you can't interconnect them its not how PCIE connection works, you can have an externally mounted GPU's using PCIE adapters and PCIE risers that have support for SFF-8643, SFF-8611 or SFF-8654 cables if you are using PCIE4.0 or PCIE5.0 you will need a PCIE adapter with redrivers or you will have unstable connection

Yup its C8

We don’t talk about that :) . Kidding, probably north of 60k .

Thanks man. Yeah the farm is pretty efficient as it is currently I do not know what I could do better apart from replacing them 12TB drives with larger ones. Currently on the lookout for a white rack to compliment the black one hope I can find something locally.

Nah its in the house above what used to be a basement but now I have converted it it to this nerd garden :D

Its getting there, its getting there. This place needs a white rack to compliment the black one. Schrack and Rittal make some white rack's, I need to get my hands on one.

Same here :D, parts are ordered so its just a matter of time before they arrive.

Yup need to try Arch there is something weird going on definitely with these AWS instance i just need to figure out what
