I just lurk here for the tech pics, please forgive me: Why does that computer have two CPUs?
Most likely for virtualization. Though in this configuration, it would be a challenge to provide the storage and ram to support more than say, 16 cores, or a standard single cpu build.
Why? NVMe drives produce more throughput and IOPS than whole SANs 7-8 years ago.
The first SAN I ever worked with was about 20 years ago
Cost close to a million dollars and was the size of two refrigerators
Just bought an NVME off of Amazon for $21 that's faster :O
Dual-socket systems are an easy way to get more cores, memory size or memory channels for your machine without buying a more expensive CPU SKU, or upgrading the platform to the next generation (which is often still years away back when those systems were operated by their former corporate owners), or building a multi-node cluster. 4-socket and 8-socket systems also exist but uncommon on second-hand market as most motherboards and CPUs do not support this feature.
They are also a good way to get more PCI-E lanes without having to go to HEDT hardware. Standard CPUs tend to have nowhere near enough PCI-E connectivity for modern times, imho.
....Dual-socket systems are almost always either server or HEDT themselves.
They also introduce different issues.
Be sure of what you're after before you move to dual-socket for PCIE lanes, and how it might effect what you're already doing.
