For customers with a requirement for increased power availability, Internap makes available redundant circuits as optional services in all of our colocation facilities. A redundant circuit does not increase the total draw available to customers, but provides a second circuit path which when properly used mitigates the potential for power outages within a customer’s cabinet or cage area.
Internap redundant circuit capability varies by facility. If available, the following types of redundancy may be considered by customers:
Internap® makes available dual-bus redundancy in certain facilities that are 2N redundant. In these facilities, Internap is able to offer colocation solutions that have true redundancy: separate A and B feeds, each of which is connected to an entirely self-sufficient backup power system including diesel generator(s), an automatic transfer switch, UPS capacity, power bus and power distribution unit. Dual-bus redundancy is not available at all Internap colocation partner facilities.
Power Delivery Unit (PDU) Redundancy
In Internap and partner facilities without 2N redundancy, customers may be provided with redundant circuits connected to a different power distribution unit rather than the primary feed. The location of the second PDU will be determined by Internap or its colocation solutions partner, and both PDUs may share an upstream power bus, UPS and/or diesel generator. PDU redundancy is not available at all Internap colocation partner facilities.
Power Breaker Redundancy
For customers seeking only separate circuit breakers, Internap’s colocation solutions will deliver a separate breakered redundant circuit from the same PDU as the primary feed. Power breaker redundancy is not available at all Internap colocation partner facilities.
