KIOXIA Adds Thin Provisioning to KumoScale Software Suite, Increases Cloud Storage Efficiency

Maximizes Flash Utilization for Disaggregated Cloud Storage While Reducing Costs

SAN JOSE, Calif., May 28, 2020 – KIOXIA America, Inc. (formerly Toshiba Memory America, Inc.), the U.S.-based subsidiary of KIOXIA Corporation, has added thin provisioning to its KumoScale™ storage software based on NVM Express™ over Fabrics (NVMe-oF™) technology. Thin provisioning joins KumoScale software’s growing list of advanced storage functions that allow for the virtualization and management of high-performance flash at data center scale.

Traditional storage systems allocate capacity beyond a user’s current needs in anticipation of future growth. This practice of ‘thick provisioning’ often reserves large amounts of flash capacity that may never be used. Through KumoScale software’s thin provisioning feature, capacity can be easily allocated to servers on a just-enough and just-in-time basis, eliminating wasted capacity. Thin vs. thick provisioning is one of many per-user optimizations available via KumoScale software’s Advanced Storage Class Specification.

“We are proud to add another advanced data service to the KumoScale software suite – further enhancing the benefits that set it apart: speed, scale, and low cost,” noted Joel Dedrick, vice president and general manager, networked storage software, KIOXIA America, Inc. “Every application has different storage requirements, and KumoScale software is designed to handle them dynamically. We will continue to expand available options in order to help more users reap the benefits of a disaggregated architecture based on an NVMe-oF shared storage model.”
