IDG News Service (San Francisco Bureau) — How reliable is your data center service provider? Perhaps not as reliable as you think.
The Uptime Institute says some data centers are playing fast and loose with its “tiering” system for rating data center reliability, making false claims or at best being economical with the truth about how resilient their facilities are.
The upshot, the Institute says, is that some companies may be running important applications in data centers that are more susceptible to failure than is advertised, and they may get a rude awakening the next time a hurricane strikes or a transformer blows out in the local power grid.
“At a time when more enterprises are moving at scale to an outsourcing option, the stakes couldn’t be higher,” said Julian Kudritzki, Uptime Institute’s chief operating officer, who along with a few data center operators is trying to raise awareness of the issue.
The Institute’s tiering system is only one way of indicating data center resiliency, but it has become well known in the industry. It gives four tiers of certification, with Tier III the most common type awarded. A Tier III data center has multiple delivery paths for power and cooling, and redundant critical components, so that downtime is minimized and maintenance can be performed without taking the computing services offline.
