HP Netserver High Density Rack Solutions Overview (LP 2000r)
4Assess the thermal dissipation and ensure that there are adequate cooling systems in place.
5Calculate the thermal conditions.When mounting multiple servers in a rack you must also manage the thermal requirements. Although the HP Netserver LP 2000r is specifically designed with excellent heat characteristics, you must know the thermal load your particular rack configuration produces. This will allow you to manage the thermal environment within the rack to provide the conditions required for optimum server operation.
The operating temperature specifications for the HP Netserver LP 2000r are:
5 to 35°C (41 to 95°F)1, 2
It is very easy to calculate the BTU/Hr an HP Netserver LP 2000r dissipates. Simply use the following formula:
Input Power (watts) x 3.41=Thermal dissipation (BTU/hr)
If we use the example with the four servers above, we can easily calculate how many BTU/hr our servers will produce:
713 W x 3.41 = 2,431 BTU/Hr
6Check your calculations.As with any calculation or measurement, it is always valuable to check your numbers more than one time.
This is also the time to make adjustments to your layout. As you have gained insight into the power needs and weight issues, you should adjust the placement of the equipment and add racks as needed. Plan for easy access to equipment, which needs regular servicing, ensure that monitors and keyboards are easily accessible to operators, and heavier items are placed low to provide stability for the system.
