Thermal Management Intel® Storage Server System JBOD 2000 Family Hardware Guide
Revision 1.42 32
5. Thermal Management
The Intel ® Storage Server System JBOD 2000 Family is designed to operate at external
ambient temperatures of between 10ºC and 35ºC with limited excursion-based operation up to
45ºC and limited performance impact. Working with integrated platform management, several
features within the system are designed to move air in a front-to-back direction, through the
system and over critical components to prevent them from overheating and allow the system to
operate with best performance.
The installation and functionality of several JBOD components are used to maintain system
thermals. They include up to three managed 60-mm system fans and one integrated 40-mm fan
for each installed power supply module. Hard drive carriers can be populated with a hard drive
or supplied drive blank.
5.1 Thermal Operation and Configuration Requirements
To keep the system operating within supported maximum thermal limits, the system must meet
the following operating and configuration guidelines:

The system operating ambient is designed for sustained operation up to 35ºC (ASHRAE
Class A2) with short-term excursion-based operation up to 45ºC (ASHRAE Class A4).
- The system can operate up to 40ºC (ASHRAE Class A3) for up to 900 hours per
year.
-
The system can operate up to 45ºC (ASHRAE Class A4) for up to 90 hours per year.
- System performance may be impacted when operating within the extended operating
temperature range.
-
There is no long-term system reliability impact when operating at the extended
temperature range within the approved limits.

All hard drive bays must be populated. Hard drive carriers can be populated with a hard
drive or supplied drive blank.

In single power supply configurations, the second power supply bay must have the
supplied filler blank installed at all times.

The system must be configured with dual power supplies for the system to support fan
redundancy.

The system top cover must be installed at all times when the system is in operation. The
only exception to this requirement is to hot replace a failed system fan, in which case the
top cover can be removed for no more than three minutes at a time.
5.2 Thermal Management Overview
In order to maintain the necessary airflow within the system, all of the previously listed
components and top cover need to be properly installed. For best system performance, the
external ambient temperature should remain below 35ºC and all system fans should be
operational. The system is designed for fan redundancy when the system is configured with two
power supplies.
