What is driving the demand for uninterruptible power supply (UPS) systems these days?
CARLINI: UPS systems are in more demand than ever—primarily in the data center. Even though the new servers are much faster and require less power to operate, the demand for computational capacity is much higher than increased server efficiencies. This drives incremental servers and storage, which translates to the need for more UPS. Another driver is integration of telecom and IT. As the industry switches to Voice over Internet Protocol (VoIP), it creates a greater need for UPS because this network technology is AC-power based. The expectation for voice transmission reliability is much higher than data transmission reliability, so UPS systems with higher built-in redundancy levels for deploying UPS in redundant configurations is now being required. PANFIL: I agree that the demand for UPS units is strong and is being driven by several factors. First, organizations are continuing to add technologies, such as servers, network switches and storage systems, that have higher power requireme
