Voltage fluctuations and outages

The MCS-200/100 is designed to provide immunity to power outages of less than one cycle. However, testing cannot conclusively rule out loss of service. To obtain the best possible performance of power distribution systems for HP equipment, observe the following guidelines:

•Dedicated power source—Isolates the power distribution system from other circuits in the facility

•Missing-phase and low-voltage detectors—Automatically shuts down equipment when a severe power disruption occurs. For peripheral equipment, these devices are recommended but optional.

•Online UPS—Maintains constant input voltage for devices and should be considered if outages of one-half cycle or more are common. For each situation, consult a qualified contractor or consultant.

You can protect the MCS-200/100 from the sources of many electrical disturbances by using:

•An isolated power distribution system

•Power conditioning equipment

•Over- and under-voltage detection and protection circuits

•Protection to reduce high-frequency electrical energy radiation

•Surge protective devices on power cables to protect equipment against electrical storms

Electrical planning around water-handling components

CAUTION: In case water is in contact with the power cables, shut down the main breaker before cleaning up water in this area.

Because of potential condensation on non-insulated water connections or leaking water connections around water-based cooling systems, consider the following during the electrical planning:

•Waterproofed connectors

•Watertight conduits for cables

•Leak detection systems

To identify waterproofed connectors, HP recommends that you use the IP rating of the connector based on the international standard IEC 60529. HP recommends a connector that is rated at least IP 67.

Cable conduits are available in different styles, depending on flexibility and materials. The most common materials are plastic, metal, nylon, or a composition of these materials. Watertight conduits are available in both flexible and hard material, depending on the application.

A leak detection system for a data center usually uses leak sensor cables, which are installed on the subfloor in a raised floor and connected to a facility management system.

Connecting to facility A/C power

The MCS-200/100 accepts AC power through two Walther Procon A5 series power receptacles located at the top rear patch panel. If available, the MCS-200 ships with one of each AC power cord set for connecting to redundant AC power busses. The NEMA L6-20 power cord uses a NEMA L6-20 male plug for connecting to a facility AC feed connector common to North America and Japan. The IEC 309 power cord uses an IEC 309 male plug for connecting to a facility AC feed connector common in various international regions.

These redundant connections and cords are optional for the MCS-100.

Modular Cooling System specifications

The HP Modular Cooling System (MCS) is a state-of-the-art solution designed to efficiently manage the heat generated by high-density IT environments. As data centers face the ever-increasing demand for processing power, traditional cooling methods often fall short, leading to inefficiencies and raised energy costs. The HP MCS addresses this issue with a scalable, flexible design that optimizes cooling performance while minimizing energy consumption.

One of the main features of the HP Modular Cooling System is its modular architecture, which allows for easy expansion and customization based on the specific needs of a data center. This scalability means that as a facility grows or changes, the cooling system can be modified without the need for extensive renovations or replacements. The MCS can be installed in various configurations, further enhancing its versatility.

The technology behind the HP MCS includes advanced cooling methods such as direct evaporative cooling and chilled water cooling. Direct evaporative cooling utilizes the principles of evaporative heat exchange to cool air without excessive energy consumption, making it an eco-friendly choice. In contrast, chilled water cooling uses a network of pipes filled with chilled water to remove heat from the server environment efficiently. This combination allows the MCS to adapt to various heat loads and ambient conditions.

Another notable characteristic of the HP Modular Cooling System is its intelligent controls and sensors. These components continually monitor temperature and humidity levels within the data center, automatically adjusting cooling output to maintain optimal conditions. This proactive approach helps to prevent overheating, reduces energy usage, and ensures the longevity of IT equipment.

Energy efficiency is further enhanced through the MCS's integration with HP's monitoring and management software. This software analyzes cooling performance trends, providing actionable insights for facility managers, enabling them to make informed decisions regarding cooling strategies. Additionally, the system is designed with environmentally sustainable practices in mind, aligning with global initiatives to reduce carbon footprints and promote green technology.

The HP Modular Cooling System stands out for its combination of innovative technologies, flexibility, and a commitment to energy efficiency. As data centers continue to evolve, the MCS remains a crucial asset in the pursuit of optimized performance and sustainability, providing a reliable solution to meet the demanding cooling needs of modern IT infrastructure.
