Transition to NVMe Should Include a Review of System-Level Power Consumption
This IDC Perspective discusses that, as more datacenters deploy NVMe technology, administrators may be in for a few unexpected surprises around energy and rack space consumption trends. This document briefly reviews how NVMe power consumption differs from SCSI and identifies two metrics (watts per terabyte and watts per U) whose anticipated evolution over time can help administrators plan for the transition to NVMe. It closes with several suggestions for IT buyers who are looking at deploying NVMe-based systems."The IT industry will be rapidly transitioning from SCSI to NVMe for performance-sensitive workloads over the next two to three years," said Eric Burgener, research vice president, Infrastructure Systems, Platforms and Technologies. "The efficiencies gained with this transition will differ somewhat from the last major transition in enterprise storage —from hard disk drives to solid-state disk drives — because of the much higher relative energy consumption of NVMe devices. Administrators will want to make sure they understand the impact of this on both power draw and rack space utilization as they plan this transition."
