ENVIRONMENTAL MONITORING UNITS
Many of the PDUs above contain environmental monitoring – the ability to interrogate sensors and report back on temperature, humidity, airflow, light sound etc. –every aspect of the microclimate in any rack or Datacenter. FCIT also offers a range of stand-alone environmental monitoring units. Our range of Environmental (Climate) Monitoring units include self contained mini units which can be powered by POE (Power over Ethernet) up through 1U Monitoring Units which can support up to 60 sensors. "Sensors" can also include metered PDUs and Switched units, so it is quite possible to mix and match PDU and Environmental products to achieve a bespoke solution for any application.
A further step in FCIT’s Environmental monitoring offering is a unit with relays which can automatically respond to alarms, by (for instance) switching on or off more fans, activating or de-activating Air Conditioning units or ventilation units, opening doors, triggering audible or visible alarms etc. This means that either the whole microclimate within the rack can be automatically controlled, or that some initial actions can be sanctioned by an on-site unit whilst waiting for human help to arrive.
FAN CONTROL SYSTEMs
The cooling of Datacenters can account for a significant percentage of the total energy bill. Air conditioning is normally set to “overcool” (better safe than sorry?) Datacenter temperature is raised massively by the hot air exhausted from Server racks – thus obviously the need for cooling. By fitting a Fan Control system into a rack the airflow inside the rack can be controlled so that the temperature is kept close to the optimum requirement of the servers, but not unnecessarily cool. The knock-on benefit of this is that no more air than is actually needed by the servers to maintain their required operating environment is passed through the rack and so a minimum necessary volume of hot air is expelled to impose cooling load on the Air conditioning units. This offers savings both by reduced usage of rack based fans and more importantly, lowers the ambient temperature of the Datacenter so saving considerable energy on cooling. Reduced fan noise in the Datacenter is a welcome and useful bonus
