SAS Mania Episode 2

So well, we got our shipment from China which took arround 2 weeks.
After that it was time to install everything.
First i needed to connect all the harddrives to the new SFF-8482 Plug.
We remember the way goes like this

So what we do is we need to connect SATA Power to the SFF-8482 Plug and the SFF-8482 Plug goes then into the Harddrive.
Which all should look then when it’s done like this.

So the question maybe some people are asking is:
Boy are these flipping Molex to SATA Connectors?
Couldn’t u just use normal SATA Power ese?


Well i could yeah but then we run into a litte problem.
See i first also did the same and just used normal SATA power cables which are included with my PSU but well they wouldn’t power on.

So after some good ol google search party i found the following

An update to the SATA/SAS spec reserves pins 1 through 3 on the power connector for extra functionality instead of 3.3v because 3.5″ drives requiring 3.3v are incredibly uncommon today. Pin 3 is now used for PWDIS (“Power Disable”) to allow backplanes / controllers completely shut down drives to either reset them or save power. If you’re powering newer drives on a backplane or with power connectors that provide 3.3v on pins 1, 2 and 3 (to match the outdated specifications), the drive will simply not spin up. 3.3v on pin 3 signals the drive to enter “Power Disable” mode. As @rubylaser noted, there is an easy work around.

Some random helpfull person on the internet which saved me hours of researching thanks brother who is called Rain

And then what can i say we had our aha moment.
I then changed the cables to normal Molex cables and also orderd a splitter from Amazon because my little Powersupply wasnt able to have enough Molex cables on there.

And after that what can i say.
I was gifted with the beautiful sound of 8 HDD’s spinning up for me which i can say was very pleasent.

Well then we had power but we had to deal with one more thing which was the Controller and how he sees the drives and interacts with them but this issue we will face in another post. (Hopefully sooner)

Γεια σου!
