KIOXIA’s KumoScale Software Suite Delivers Fast, Resilient, Elastic Storage for Kubernetes Containers

KIOXIA Highlights New Functionality at KubeCon

SAN DIEGO, Calif., November 18, 2019 – KIOXIA America, Inc. (formerly Toshiba Memory America, Inc.), the U.S.-based subsidiary of KIOXIA Corporation, today announced that its KumoScale™ storage software with NVM Express™ over Fabrics (NVMe-oF™) now includes a robust Container Storage Interface (CSI) driver that is tightly integrated with the Kubernetes® container orchestration framework. KIOXIA America will demonstrate KumoScale software’s CSI driver, along with other new features, at KubeCon from November 19-21 at the San Diego Convention Center.

An open source application programming interface, CSI provides a uniform way for storage providers to make block storage accessible to cloud orchestration frameworks. It has been adopted by Kubernetes and others and is supported by a growing list of storage array providers. The KumoScale CSI driver provides a standardized way to connect control planes to storage, while still allowing for a high level of flexibility in terms of the requirements applications can place on storage resources.

Additionally, KumoScale software extends the Kubernetes concept of “Storage Classes” and “Storage Class Specifications” to provide a convenient way for users to individually specify a rich set of requirements for each storage volume. This application-centric labeling is then carried through all of KumoScale software’s management and reporting functions, enabling users to see performance data filtered and expressed in the ways that matter to them. For example, KumoScale software’s Advanced Storage Class API mirrors the Kubernetes method of providing topology awareness and specifying failure zones, allowing KumoScale to make intelligent data placement decisions automatically.

“We recognize that Kubernetes has become a critical, popular orchestration framework and have designed KumoScale software to fully embrace its constructs,” noted Joel Dedrick, vice president and general manager, networked storage software, KIOXIA America, Inc. “If you’re using Kubernetes for container storage, we make it possible to do so with higher performance and exactly the right amount of provisioned storage.”

Developed with a strong focus on virtualizing and managing high-performance flash at data center scale, KumoScale builds on KIOXIA’s heritage as the inventor of NAND flash and an SSD pioneer to deliver the unique performance and endurance characteristics of NVMe storage as a networked service.

At KubeCon, KIOXIA is hosting meetings at its booth #S13 and will have a series of KumoScale demos and product overviews on display. For more information, please visit or
