KIOXIA KumoScale Software v3.19 Delivers Automated SSD Lifecycle Management 

SAN JOSE, Calif., Dec. 2, 2021 -- KIOXIA America, Inc. has released version 3.19 of its KumoScale storage software built around the NVM Express over Fabrics (NVMe-oF) protocol with enhanced automation and orchestration support. Designed for cloud-centric deployment at data center scale, the KumoScale based storage platform delivers high performance NVM Express (NVMe) flash storage as a disaggregated networked service. Major features in KumoScale software version 3.19 include SSD device management and enhanced NVMe-oF specification support for the latest release of OpenStack infrastructure software, codenamed “Xena.”

Operator-driven SSD Device Management

Version 3.19 adds automation support for lifecycle management of NVMe drives in disaggregated storage nodes. This means that storage administrators now can monitor and manage storage resources at all points from the client all the way down to the firmware of the storage devices being used. SSD functions supported include:

  • Adding and removing SSDs from storage pools
  • Migrating data on one SSD to another without interrupting I/O
  • Blinking the LEDs of SSDs safe for physical removal
  • Upgrading SSD firmware

Importantly, data relocation can be performed without disrupting storage traffic, allowing online upgrade of SSDs to add capacity or performance.

Declarative Control

KumoScale maintenance operations are declarative, rather than imperative. This makes otherwise risky and complex activities easy and safe, by embedding the logic for how to accomplish them into the system itself. This is done via a simple, but deceptively powerful, control structure called an “operator.” Pioneered in the Kubernetes container orchestration framework, operators allow the user to simply specify the desired state of the system (e.g. which SSDs should be empty or their desired firmware version), and the system will act to move itself to that state. Operators are provided for a variety of maintenance and configuration actions in addition to SSD management.

OpenStack Software Support

KumoScale storage software version 3.19 includes native integration with the latest OpenStack infrastructure software release, codenamed Xena. As an active member of the OpenStack contributor community, KIOXIA has made several enhancements to seamlessly integrate high performance NVMe-oF storage to this popular open source infrastructure framework. KIOXIA contributions enhance NVMe-oF storage capabilities in the OpenStack environment:

  1. The Xena release os-brick nvme.py connector broadens support to include many commonly used Linux distributions.
  2. The Xena release nvme.py connector has been enhanced to support volume snapshots.

These enhancements make NVMe-oF technology more efficient for large scale OpenStack infrastructure deployments.

KumoScale software version 3.19 also includes additional enhancements to add support for the Ubuntu distribution of Linux, the latest Kubernetes CSI version, and adds CSI and Ansible support of snapshot and clone functionality.
