The Supermicro CSE 745BAC R1K28B2 is a high performance 4U server chassis designed for enterprise environments that demand versatility and power. Engineered to function as either a tower or a rackmount unit, this chassis provides a robust foundation for mission critical applications, including database management, virtualization, and high frequency trading. It supports dual processor motherboards up to E ATX size, making it ideal for system integrators building powerful workstations or servers. With a focus on reliability and uptime, the chassis features a 1280W redundant power supply system certified at the 80 Plus Platinum level. This ensures high energy efficiency and continuous operation even during power module maintenance. The storage subsystem is equally impressive, offering eight hot swap 3.5 inch drive bays connected via a high speed SAS3 backplane, enabling 12Gbps data transfer rates. Advanced cooling is managed by five heavy duty PWM fans, maintaining optimal thermal conditions for high TDP components.
