iTservercenter the next generation colocation facility has a UPS system designed at 2N and a mechanical chiller system also designed at 2N. Our renowned data center design engineer, Peter Gross of EYP, describes 2N system design as, “An Order of Magnitude more reliable than N+1.”
The vast majority of data centers utilize an N+1 UPS system design. By contrast, iTservercenter utilizes a 2N on site back up power system design.
Why is a 2N back up power system important?
In the event of a local utility power outage, the on site back up power system needs to prevent a power outage that lasts more than 4 milliseconds. During this seamless transport of power, within 4 milliseconds, the colo customer is at the mercy of the Uninterruptible Power Supply (UPS) system. After 4 milliseconds without power, the servers and other computer equipment will sense the power outage, suffer downtime and need to be rebooted.
In a 2N design, each UPS module has its own backup UPS module. Whereas in an N+1 design, multiple UPS modules only have one backup UPS module. In the event of failure, of 2 UPS modules in an N+1 system design, the second UPS module has NO BACKUP.
iTservercenter is Doubly Redundant for each of the Threshold Issues for customers looking for a Next Generation Colocation Service:
Doubly Redundant (2N Design) UPS Electrical System
Each of these above items are crucial threshold issues which are used as the Critical Decision Criteria, the critical differentiators which the experts use to determine if a data center is in fact a next generation data center and if it will endure the same typical historical problems as others.
