Project Overview: Tianyi Cloud, operated by China Telecom Cloud Computing Company, is an operator-level one-stop information service portal that provides users with a full range of products including cloud hosts, cloud storage, cloud backup, desktop cloud, and big data, while also offering customized cloud solutions for industries such as government, education, and finance. Business Results: For this Tianyi Cloud project at China Telecom Dali Branch in Yunnan, the cabinet specifications used are 600mm×1200mm×2200mm (W×D×H). The micro-module aisle containment type is a closed cold aisle, with a double row of 26 cabinet positions, including 21 IT server cabinets, 4 row-based air conditioners, and 1 precision power distribution cabinet. The designed power per single cabinet is 5kW, and with 21 IT server cabinets, the total designed power is 105kW, with the entire micro-module power not exceeding 105kW. The air conditioning uses 30kW row-based air conditioners, configured in a 3+1 manner. Under normal conditions, 3 units operate, providing a maximum cooling capacity of 120kW. The system features overall group control, with rotating standby, and the cooling capacity can be dynamically adjusted based on the load. The monitoring system is based on the Linux operating system platform, with a standard 32G storage capacity, supporting APP and web browsing and configuration. It collects data from power supplies, air conditioners, temperature and humidity sensors, smoke detectors, etc., via RS485/TCP/IP and transmits it to the monitoring server. Through the display and analysis of monitoring data, it enables functions such as device monitoring, notification, and alarm.
