Hitachi Vantara has emerged as a leader in energy efficiency for block storage arrays, surpassing competitors such as Dell, HPE, IBM, and Pure Storage in data access per watt. The company’s VSP One Block array has achieved the highest rating for input/output operations per second (IOPS) per watt, according to the US Energy Star agency. The array scored an impressive 537.8 in the Energy Star NVSS Disk Online 4 category, which evaluates solid state drive arrays.

Notably, Hitachi Vantara’s VSP arrays occupy the top three positions in this category. The Energy Star’s “Trans Optimal Point Hot Band Workload Test” (TOPHBWT) assesses the efficiency of storage devices in terms of IOPS per watt during a high-demand “hot band” workload. This workload focuses on frequently accessed data subsets. The TOPHBWT is used to predict the optimal performance point for deployed storage devices in terms of IOPS per watt.

Octavian Tanase, Chief Product Officer at Hitachi Vantara, highlighted the significance of this achievement, stating, “Our Virtual Storage Platform One Block storage appliance exemplifies our vision for the future, delivering powerful, reliable, and eco-friendly solutions that drive value for our customers and help significantly reduce carbon emissions.”
