The largest dust storm in recorded history hitting much of the east coast of Australia yesterday, but data centre providers are reporting customer servers have come through unscathed.
Aidan Tudehope, managing director of hosting for Macquarie Telecom said the Macquarie Hosting data centre in Sydney had not experienced any adverse affects from the dust storm.
“The Macquarie Hosting data centre in Sydney is operationally equipped for air quality issues,” Tudehope said. “We predominantly recycle air for cooling purposes and our air conditioners have filtration systems to remove any dust particles from the air.”
With reliability being obviously critical to customers, the hosting company has also undertaken precautionary measures to ensure service levels are maintained.
“We shut-off external mechanical ventilation systems to prevent dust entering the environment,” Trudehope said. “Staff were on heightened alert for any issues in the facility and a response plan was in place.”
Despite being based in Melbourne, Primus Telecom wasn't taking any chances, according to its data centre team.
“Our computer room fresh air intake is filtered and an air-conditioning technician was on-site all day yesterday ensuring that the intake filters servicing the building did not clog,” the team told Computerworld in an email.
“Air-conditioning units coils were inspected during the day for build up of dust. Our computer rooms also have positive pressure to exclude dust ingress from within the building as well as sticky mats at ingress points.”

Although dust may strike many as being cause for little concern, the Primus team advise that, depending on the chemical makeup, dust particles have the potential to be electrically conductive and may cause more than a server fault.
“It is always recommended to power down any effected servers or infrastructure, disassemble them to their component/module level and clean them in a clean, anti-static environment,” the team said. “Particular care should be taken to ensure all fans and heat-sinks are cleaned, and all fan bearings are checked for reliability.”
The team advises smaller organisations who may be managing their own data centre facilities to always ensure that all air filters within cooling systems are regularly checked and cleaned/replaced as per manufacturers guidelines at a minimum.
Any room or environment that encloses server equipment should be sealed where possible, with positive pressure to exclude dust ingress from within the building and use sticky matts at ingress points.
Loren Wiener, product manager, data centres and hosted solutions at NEC Australia, said there had been no impact to its Queensland Polaris data centre as a result of the dust storms.
“NEC data centres weren’t impacted because of the quality of our filtering system and also because of the newness of the system – as with any technology, newer data centres naturally have the best protective mechanisms built in,” he said.
Wiener said depending on the age of the data centre in question, filtering – especially under load – could cause issues.
