3U Core i7 Servers

3U Servers occupy three rack units, or 5.25 inches (133.35 mm) in height, and provide a versatile solution for enterprise applications that require multiple full-height PCIe cards. These servers are ideal for businesses needing powerful networking, storage controllers, or specialized hardware. Many 3U servers also offer support for legacy hardware such as 5V PCIe cards, full-sized telemetry and capture cards, and offer 5.25" bays for mobile racks, optical drives, or other additional specialized hardware devices. Whether for virtualization, data processing, or custom appliance servers, 3U servers deliver an ideal balance of expandability, and custom or legacy integration while still conserving on rack space, with up to 14 3U servers able to fit in a standard 42U rack. One thing to keep in mind is that 3U servers may not have the space required for over-sized PCIe cards such as the latest powerful GPUs, which often have plastic shrouds that exceed 3U height. If over-sized PCIe cards are needed, a 4U server may be a better fit for your project.
