Backplane features SAS747TQ

I ran across this Supermicro backplane and it is loaded with all kinds of components.



My cheapo no name NAS case as well as some of my other prebuilt NAS's have almost naked backplanes.

What are some of the main features that they are missing that are common in the enterprise world?

Basically, this is actually 2x backplanes in 1. Each backplane has its own I2C and SGPIO ports, and headers for LED status, fan control, and power.

So I picked up a Supermicro backplane to fit my 4bay case. It has I2C and SGPIO.

Would there be benefit to making one of those connections to my board or is staying with the SATA alone.

Not sure my X10SDV can take the I2C as it provides two connections one labeled for IPMI and one for PCIe cards.

The only real benefits for I2C/SGPIO connections are 1) the ability to control drive LEDs using the sesutil utility, and 2) some additional HW integration with Supermicro front panels for alarming. I run mine disconnected.

Cool thanks, I ran across the same in my research.

I'm trusting there will be a benefit of using that backplane vs the stock one which appears on the simple side with no management chip, one less power connection etc.

The benefit vs a no-name backplane is better trace engineering, and overall better longevity.
