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.
