Supermicro 1U converting to redundant power supply

[J--]

Is it as simple as swapping out the PDUs and buying two new slimmer PSs?

And also the rear window and PSU carrier..

Assuming you are willibg to buy used off eBay its generally cheaper to swap out the chassis and sell the old one.

I am thinking it will depend on the model 1u chassis you are working with.
You may want to add that to help us help you.

I would suggest @PigLover has a wise course of action.

If you have a chassis with a single PSU in a redundant PSU capable chassis then you can simply buy and plug in the second PSU.

You will also need to ensure you have parts like the power distribution board and proper cabling to the chassis. That depends on the chassis used.

Given used chassis pricing, it is usually cheaper/ easier to just ebay the old and new chassis.

@Netwerkz101 Thanks, I actually didn't know what I was getting until today. They're old Softlayer units, it's the CSE815 chassis with X9SCI-LN4F mobos. I picked up two @ $75 shipped/unit.

What's the expected price to get into a redundant chassis? I guess I shouldn't be expecting a similar deal, but it's probably worth the price of admission to get redundancy instead of scrambling to a colo site after hours.

@J-- does your colo have A+B feeds? Adding a redundant PSU also means that you have a power distribution board. PDB's are a higher failure rate item. They also lower power efficiency.

Late last year I removed one PSU from each of my servers. I just assumed that using one PSU they would consume less power. Nice to see that my assumption was correct.

Another side benefit is I have an abundance of spares.
