Major physical exposures common to a data centre
Most operations managers do a good job of keeping their data centres up and running. Many workplaces go for years without a experiencing a major powercut specifically caused by the physical environment. But the infrequent nature of these types of powercuts can often lull managers into a false sense of security and lead them to overlook the risks to which they may be exposed. Here are the most common of these:
- Physical wiring diagrams out-of-date
- Logical equipment configuration diagrams and schematics out-of-date
- Infrequent testing of UPS
- Failure to re-charge UPS batteries
- Failure to test generator and fuel levels
- Lack of preventive maintenance on air conditioning equipment
- Public address system not tested
- Fire suppression system not recharged
- Emergency power-off system not tested
- Emergency power-off system not documented
- Infrequent testing of backup generator system
- Equipment not properly anchored
- Evacuation procedures not clearly documented
- Circumvention of physical security procedures
- Lack of effective training for appropriate personnel
The older the data centre, the greater these exposures become. I have had clients who have collectively experienced at least half of these exposures during the past three years. Many of their data centres were less than ten years old.
Preventative maintenance, testing, inspections or any combination of these should occur at least once a year. I have worked with some workplaces who have annual maintenance contracts in place for their physical facilities, including onsite inspections, but choose not to exercise them. Un-tested safeguards, un-inspected equipment, undocumented procedures and un-trained staff are all preventable invitations to disaster.
