HP Modular Cooling System frequently asked questions

Question

Answer

 

 

What cooling capacity ranges are

The cooling capacity of the heat exchanger units depends on the

available in the MCS unit?

water supply temperature and the server inlet set point. The MCS

 

unit is capable of cooling rack-mounted components consuming up

 

to 35 kW of electrical power.

 

 

Is special IT equipment required for

No, all IT equipment that uses the front-to-back cooling system (99%

use with the MCS unit?

of IT equipment) can be used without restriction in conjunction with

 

the MCS unit.

 

 

Does the additional heat from the

In some cases, up to 10% of the total power supplied to the rack

MCS unit increase the room

may be lost to the room, depending on the server air setting and the

temperature?

room temperature.

 

 

Can the level of heat removal be

Yes, the control system automatically adjusts the water flow and air

regulated in proportion to the waste

flow to remove heat generated in the rack.

heat generated?

 

 

 

How is water connected to the MCS

The water is connected to the unit using a 1 1/4 in flexible hose

unit?

and quick-disconnect automatic shutoff hose fittings. For more

 

information, see the HP Modular Cooling System Site Preparation

 

Guide on the HP website.

 

 

Can the MCS unit operate with the

Yes, due to the air curtain effect, the air will function normally with

front or rear door open?

little air lost. When the doors are open during operation, room air

 

mixes with air supplied to the servers.

 

 

Does the MCS unit require

No, assuming that the water quality is maintained, the MCS unit is

maintenance?

maintenance-free. For more information about water quality, see the

 

HP Modular Cooling System Site Preparation Guide on the HP

 

website.

 

 

Is a false floor necessary?

No, a false floor is not necessary to operate the MCS unit. For more

 

information, see the HP Modular Cooling System Site Preparation

 

Guide on the HP website.

 

 

Does condensation form?

During normal operation some condensation may form, but the MCS

 

unit condensation control system ensures that the condensation does

 

not reach any rack-mounted components or cause any damage. In

 

most cases, the condensation evaporates prior to reaching the MCS

 

unit condensation control system.

 

 

How does the MCS unit control

There is some room-air interchange, so the moisture content of the

humidity?

air inside the unit is the same as the room.

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.
