I've seen this a lot in contexts with specific workloads the last 10 years or so. With both physical space and PCIE lanes being factors, as well as how you handle virtualization/barebones setups. This can help with simplifying failover as well for HA. For example, storage servers usually are full to the brim of harddrives and SSDs. Then you might need to process your data on GPUs/CPUs where you have specific servers specced out with more CPU/GPU resources.
