    ■      Comprehensive monitoring: The system provides rich real-time and history statistic data, to help users know the comprehensive system operation status and resource usage; It monitors environment temperature, power, and fans in real time and provides remote monitoring function. 

    ■      Convenient maintenance: The controller, power, fan and hard disk support hot swap and disk roaming and mixed insertion,  to reduce maintenance complexity.

    5.Green, Energy Saving, and Environment Protection

    ■      The system uses the industry-leading hardware speed decrease and sleep technology to reduce energy consumption.

    ■      Mute fan design with intelligent speed control: low power consumption and low noise.

    ■      The CPU intelligent frequency conversion function can adjust the CPU operation frequency intelligently according to service pressure

    ■      Green and harmless: The system has no lead, so it is environment protection.
