Strange computer part

Recommended Posts

Posted · Original PosterOP

So there I was at work taking calls, replacing RAM, swapping power supplies, and updating tickets, when I get a call to replace a bad hard drive. I go over there I power off the computer, tear out all the plugs in the back, pull out the computer, and open the side panel. Only to find the strangest expansion card I have ever come across. At first I thought it was some weird GPU with modular RAM and a CPU heat sink but it turned out to be a completely separate board from the GPU with a desktop CPU and 4 memory slots. The entire computer was built around this card with a custom expansion slot on a custom motherboard in a custom case. This is an HP computer and a google search brought it up right away. But I'm still wondering why not just use a dual socket motherboard?

Because that would make too much sense?

Its probably for diffrent config. Config x has one cpu and y amount of ram, and config z gets you 2x cpu and 2y ram. 


I am still TechWizardThatNeedsHelp, just less of a mouthfull.

that makes sense, nowadays I would just use VMs for that but I get the feeling this is kinda old.

It didn't feel that heavy but the case had a steal slot for the whole thing to slide into

It's not that old; I use a Z640 for work. I've never opened the case though. I probably have one of those, and don't even know it.... I do know for sure it's a dual CPU, so it probably has it. I think it's fascinating. What's its connection to the main board? Is it PCIe or something else?

And I don't know about individual parts, but I do know that the machine as a whole is very heavy....

It's not PCIe, its those 4 large gray blocks with a bunch of holes, I doubt if PCIe would even have enough bandwidth for something like this. You can also see a 20pin power connector in the lower left of the image.

Ok, I see.

Also, I found this video which seems to start in the middle of a presentation, but is an HP rep explaining that the weird add-in board serves two purposes: it is more compact than a single large 2-socket motherboard, allowing for a smaller case form factor, and it makes it so that the motherboard is common with the single-processor Z4 series, thus reducing engineering and manufacturing costs.

Looking at this thing it might be space constrains.

I can see it helping to make it smaller but not cheaper. The amount of development it takes to make a custom connector is repetitively light in the world of computers but still a huge undertaking. However you can pick up a refurbished z640 like the one I found for 500-600usd while the new version is 2000-3000usd.

Dell does the same thing on their workstations.  Here is a pic of the port on a dell 7820.spacer.png

 

The card would sit above the first CPU.
