Enclosed cold/heat passage technology is adopted to avoid mixing of cold/hot air flows and substantially reduce energy consumption. Inter-rack air-conditioners are adopted to achieve near-end refrigeration and substantially increase refrigerating efficiency in a high-density environment.  Compared with the traditional data center, energy consumption is reduced by 30% to 50% and PUE is reduced to 1.02 to 1.25.

Flexible Expansion

Modular parts and uniform interface standards are adopted to facilitate capacity expansion using fully integrated racks or modules as necessary, resulting in investment savings. On demand capacity expansion at a rated power density of 1kw to 21kw is supported for a single cabinet.

Smart Management

The management system supports industry-standard Modbus, SNMP and background communication protocol to monitor power, environment, video and access basic infrastructures of the data center.  Alarm management, statement management, work order management and efficiency management are integrated to achieve all-around smart management. Support standard L2 network administration, provide external interfaces of various standards for interfacing with third-party systems.

4) Single-point lock that locks reliably and opens lightly without noise is adopted for the front door. The lock core turns flexibly without clogging and is designed for both left and  right-handed users.

5) Connecting-rod-type three-point lock is adopted for the rear door. It has a simple structure, locks reliably and opens lightly without noise. The lock core turns flexibly without clogging and is designed for both left and the right-handed users.

6) The front and rear mesh doors are made of 1.5mm-thick cold-rolled steel plates; column material: 2.0mm-thick cold-rolled steel plates; frame material: 1.5mm-thick cold-rolled steel plates.

7) Each cabinet is configured with two PDU power strips which are installed vertically and do not occupy U spaces.

3, Enclosed Cold Passage System

In order to reduce energy consumptions of the data center and increase the cooling efficiency of air-conditioners, an enclosed cold passage design is adopted for the Inspur Modular Data Center. The design is as follows:

1) Enclosed cold-passage product comprises the terminal door, skylight, passage ceiling and monitoring attachments.

2) The door assembly comprises of dual push-open doors. The mainframe material is quality cold-rolled steel plate that conforms to GB11253 and is powder-coated on the surface. The doors have a tempered glass window and the tempered glass conforms to 3C certification requirements and GB15764.2 in a thickness of not lower than 4mm.

3) Two types of skylights, including fixed and flip-open, are designed to support entry of firefighting gases into the passage. The skylight is made of large-area transparent acrylic (PMMA) boards with a light transmissivity of at least 90%. The acrylic boards conform to GB/T7134 with a flame retardance of at least UL94-HB;

4) Flip-open skylight operates jointly with the monitoring system (e.g. fire alarm signal, temperature and humidity alarm signal, camera, etc). In case of fire, the flip-open skylight will flip open. The flip-open skylight is made of transparent acrylic materials.

5) Other parts include baffle plates at the bottom, LED lighting strips, temperature and humidity sensors, acoustic and light alarms, cameras, etc. These attachments are directly mounted in the enclosed cold passage and play a role in sealing, lighting and monitoring.

6) The passage is designed with an LED auxiliary lighting system to ensure illumination of at least 500LUX. Auxiliary lighting system is manually turned on.

7) A monitoring unit is designed to monitor the temperature, humidity, smoke and other environmental conditions in the passage. Other than monitoring the cold passage environment, it can also be connected to third-party alarm signals and can operate jointly with the control box featuring a top panel which can be opened.

8) Cold passage sealing unit is shown as follows:

4,Air-Conditioning System Design

Inter-rack air-conditioning is a new type of machine-room air-conditioner developed for high-capacity servers. It is characterized by horizontal air feeding mode and overcomes the defects of conventional precision air-conditioners, i.e. insufficient cold, dehumidification, energy inefficiency and frequent hot spots arising from air feeding. It has advantages such as automatic variable-capacity operation, high return air temperature, short air stroke, operation in full heat display, high heat conversion efficiency and effective prevention of hot spots.

5, Monitoring System

This module includes a comprehensive monitoring system. When multiple modules are combined in the same machine room, they can share one set of monitoring software and platform.

The centralized monitoring system of the data center machine room comprises of the following subsystems: Power distribution monitoring subsystem, generator monitoring subsystem, UPS monitoring subsystem, ordinary air-conditioner monitoring subsystem, precision air-conditioner monitoring subsystem, water leakage detection subsystem, temperature and humidity monitoring subsystem, door magnet subsystem, access control subsystem, video monitoring subsystem, fire monitoring subsystem, infrared monitoring subsystem, DC power source subsystem, etc. The various subsystems are interconnected via an RS485 bus and network communication to form a smart, centralized monitoring system for machine room power and environment conditions.

All devices in the machine room can be directly connected to the sever for the monitoring center via several types of communication media (such as RS485, RS232, SNMP and LANWORKS); the monitoring center server performs data capture, calculation and analysis, data storage, alarm activation, alarm processing, logic control and provision of real-time monitoring data services to remote clients. It is also possible to perform remote monitoring, data search, data printing and maintenance management through one or several remote client hosts or web browsing.
