With a growing number of organizations seeking to support seamless communication between multiple locations, the network closet has taken on an increasingly critical role. Switches, routers, firewalls, SD-WAN and other appliances now require always-on computing, making the task of securing these communication points against potentially devastating power anomalies and outages an absolute necessity.
As Voice-over-IP has developed into a universal technology, its deployment has been made significantly easier through the use of Power over Ethernet (PoE). However, the power requirements of the core network switches that provide PoE capabilities have increased exponentially, at a rate of 50 watts per Ethernet port. As a result, the 1 or 2 kVA UPS that adequately powered these devices just a few years ago is no longer sufficient; instead, a 5 or 6 kVA UPS is now needed. For some large PoE deployments, UPSs of 10 kVA or larger are even demanded. Furthermore, because VoIP requires extended runtime to allow for continuous phone operation – typically 30 minutes to 2 hours – the addition of EBMs (Extended Battery Modules) to the base UPS has become standard.
Currently the fastest growing segment in the industry, Hyperconverged Integrated Systems (HCIS) have taken the server market by storm. With the ability to easily scale as customer needs expand, the technology offers an attractive, pay-as-you-grow approach. When it comes to safeguarding the solution, a 2 kVA UPS typically provides ample power protection for a base four-node HCIS, with the UPS expected to afford scalability as the number of server nodes grow.
