Rack spacing and airflow recommendations:
When Quintessence is to be rack-mounted, we recommend allowing one RU of blank space below the unit,
in order to allow for optimum air flow to cool the equipment.
However, in the following specific circumstances the bottom air intake can be obstructed and machines
may be stacked without the recommended blank space:
1.
Machine room or rack ambient temperature is kept below 25°
2.
Side air intake is kept completely free of obstacles (rack mounting rails, cables, etc.) and ample airflow
is available in the left side of the rack
3.
Rear air exhaust outlets also are kept as unobstructed as possible (tidying the cabling out of the way of
PSU fan and chassis’s fans is a must) and ample air flow is available at the rear of the rack
On the other hand, in the following situations the bottom air intake should be left completely open:
4.
When multiple high RPM (SCSI / FC / SATA 10’000rpm or more) hard drives are installed in the
machine
5.
When a Dual Xeon machine is used for processing intensive tasks such as HD Video playback and/or
recording
So as rule of thumb, while the bottom air intake of a standard VCube / Pyramix or of a Luxor server with
external storage can, under specific conditions, be obstructed without problem,
it is highly recommended
that a VCube HD2k or a Luxor server with internal storage is installed with a
blank space below the unit
.
In the Table below, differences between open and closed bottom air intakes are displayed in Celsius. The
sensor was placed in the centre of the chassis, immediately behind the internal hard drives.
Warning! If in any doubt when installing, please check that the internal temperature of your
machine remains within the range shown.
