2.4 Installation Environment
Sufficient consideration of the installation environment should be taken to ensure proper use of
the ETERNUS DX Disk storage system. Using the ETERNUS DX Disk storage system in an
environment that does not satisfy the installation environment requirements may cause a failure
to occur with the ETERNUS DX Disk storage system.
2.4.1 Air Conditioning
It is important to consider the flows of cooling air (intake air) and exhaust air for the installation
location. The temperature in some ETERNUS DX Disk storage systems may rise when exhaust
air is taken in from other ETERNUS DX Disk storage systems. In addition, check other factors
that might affect the usage environment temperature, such as the room size, whether other
ETERNUS DX Disk storage systems are installed, and how many people are present in the
room.
When installing air conditioning, the ambient temperature should be considered.
● Ambient temperature
An ETERNUS DX Disk storage system is cooled by taking in air through the front intakes and
pushing out the exhaust air through the rear of the ETERNUS DX Disk storage system. If the
intake air temperature does not meet the ambient environment conditions, a temperature
error occurs and the power of the ETERNUS DX Disk storage system is shut down.
- Front intake air temperature
Make sure that the front intake air temperature is between 5 and 40
°C.
- Rear exhaust air temperature
For example, when the intake air temperature is 40
°C, the exhaust air temperature is 45°C
or higher.
Check the heat generation amount and the exhaust air amount that are listed in "2.1
Installation Specifications" (page 26) for the necessary cooling capacity of air conditioning.
2.4.2 Earthquake Resistance
Take the necessary measures (e.g. secure the rack to the floor or wall) to prevent a rack in which
an ETERNUS DX Disk storage system is installed from falling down when earthquakes occur.
Earthquake countermeasures vary depending on the installation location, the floor conditions,
and the type of rack that is used. Contact your installation contractor for more details regarding
earthquake countermeasure methods and how work should be conducted.
