The Nucleus RM Rear I/O system is a compact, high-performance 3U rackmount server that is only 20" deep, making it suitable for space-constrained environments. It features powerful Intel Xeon or Core i7 processors, large memory and storage capacity, and multiple PCI expansion slots. As a server, it can run major operating systems and virtualization software, and as a workstation it supports high-end processors and graphics cards. Its small size allows it to fit in vehicles, bases, and broadcast trucks while still delivering powerful processing capabilities.
