Rackmount servers are typically 19” wide and the standard height is 1.75” (1U). They can also come in a larger 2U, 3U, or even 4U heights that allow more room for additional processors and other components.

As part of the NVIDIA AI Computing by HPE portfolio, new HPE ProLiant Compute servers are optimized for enterprise AI workloads such as computer vision inference, generative visual AI, and end-to-end natural language processing. From inferencing to fine tuning, unlock new opportunities for your organization.

Rack servers, also known as rack-mounted servers, are versatile and can support various environments. They are secured in the rack using screws or rails. Blade servers are smaller than rack servers and cannot be stacked. Due to their smaller size, they need more space for components like memory and CPUs.

However, the most common server rack size you'll encounter in data centers is 42U. A 42U rack is one designed to accommodate 42 servers (the "U" stands for "units," which in this case refers to servers).
