4U Rack Servers

4U Rack Servers occupy four rack units, or 7 inches in height, and are unmatched in terms of expandability and power, making them the top choice for projects requiring maximum PCIe card support and storage capacity. These servers provide ample internal space for hardware additions, and full-height or oversized PCIe cards such as powerful GPUs that would not fit in a 3U or smaller chassis. These servers support versatile power options, and can provide all the way up to 48 hot-swap bays for high-capacity storage. Perfect for data centers or virtualization environments that require management of vast amounts of data, or unique and demanding projects that require the utmost expansion capability. 4U Servers are limited in redundant power supply options, if redundancy is needed a 2U or 3U server may be a better fit for your project.
