KIOXIA’s KumoScale Software Adds Support for PCIe 4.0

Version 3.16 Also Enables Faster NVMe-oF Storage Management Capabilities, OpenStack and Kubernetes Support

SAN JOSE, Calif., November 24, 2020 – KIOXIA America, Inc. (formerly Toshiba Memory America, Inc.) has introduced a new version of its KumoScale™ storage software based on NVM Express® over Fabrics (NVMe-oF™) technology.  KumoScale software version 3.16 delivers support for PCIe® 4.0 ecosystem components, including servers, network interface cards (NICs) and SSDs.

Designed to double the performance of client, server, and storage systems, PCIe 4.0 is driving new performance levels for cloud and enterprise applications. KumoScale 3.16 takes advantage of the faster connections offered by PCIe 4.0, enabling cloud deployments to serve more users per storage node – and leading to improved operational costs.
Additional enhancements included in Version 3.16 include:

  • 3rd-party Application Hosting Framework KumoScale storage nodes can now provide unified storage to cloud environments.  High performance native block, along with file and object services, are now under a single framework.
  • General Availability of a Kubernetes® CSI driver, enabling KumoScale to seamlessly provide storage services to one or more Kubernetes clusters.  The CSI driver is available for download from the CNCF repository.
  • Technology Preview of an OpenStack® Cinder driver that supports core storage functions, snapshots, and thin provisioning for OpenStack clusters.
  • Multi-Tenant Virtual Cluster Support: Enhances security and media utilization by isolating tenant workloads, and allows KumoScale to simultaneously provision storage to multiple client clusters using different control APIs.

“Customers demand the best performance from their cloud deployments, and KumoScale allows customers to maximize their flash and compute resources,” said Joel Dedrick, vice president and general manager, networked storage software, KIOXIA America, Inc. “With support for PCIe 4.0, KumoScale software further accelerates the performance of their NVMe-oF storage. Release 3.16 combines PCIe 4.0 support with other new features that enrich KumoScale technology and make it one of the most robust NVMe flash as a service solutions available today.”
