KIOXIA KumoScale Software v3.20 Delivers Deployment Flexibility, NVIDIA Magnum IO GPUDirect Storage and OpenID Connect Support

Includes Additional Bare Metal Deployment Options

SAN JOSE, Calif., April 12, 2022 –  KIOXIA America, Inc. has released version 3.20 of its  KumoScale™A new window will open. storage software built around the NVM ExpressTM over Fabrics (NVMe-oFTM) protocol. Designed for cloud-centric deployment at data center scale, the KumoScale storage platform delivers high performance NVM Express (NVMeTM) flash storage as a disaggregated networked service. Major features in KumoScale software version 3.20 include additional bare metal deployment options, seamless support for OpenID® Connect™ 1.0, and support for NVIDIA® Magnum IO GPUDirect Storage®(GDS).A new window will open.

Additional Bare Metal Deployment Options
In addition to the KumoScale software’s streamlined appliance install, KumoScale software version 3.20 adds an option to deploy on generally available commercial operating systems. Most large data centers deploy architectures that have very specific requirements for security, monitoring, telemetry and networking which requires that storage subsystems support OS customization to integrate into these environments seamlessly.  KumoScale software “managed mode” enables complete flexibility for engineering and security administrators to configure, integrate and control the KumoScale software storage layer OS environment, while KumoScale software “appliance mode” provides simpler installation and automated deployment with reduced deployment complexity for small and medium enterprise customers but with more limited OS configurability.

NVIDIA Magnum IO GPUDirect Storage Support
Version 3.20 adds support for NVIDIA GDS. GDS enables a direct data path for direct memory access (DMA) transfers between GPU memory and storage, which avoids a bounce buffer through the CPU. This direct path increases system bandwidth and decreases the latency and utilization load on the CPU. KumoScale software behaves as a storage adapter to GDS.

Said Scott Nelson, senior vice president and chief marketing officer at KIOXIA America, Inc., “We are proud to work with NVIDIA to deliver the power of NVMe technology into GPUDirect applications using the KumoScale software-defined platform to maximize the flexibility and cost-effectiveness of NVMe storage.”

“AI and other breakthrough cloud technologies have the potential to solve some of society’s most difficult challenges - and they’re transforming data center architectures,” said Rob Davis, vice president of storage technology at NVIDIA. “NVIDIA’s accelerated computing platform enables storage innovators such as KIOXIA to equip customer data centers with the extreme performance required to tackle next-generation workloads.”

OpenID Connect Support
Version 3.20 adds support for third-party OpenID Connect 1.0. OpenID Connect is an identity layer on top of the OAuth 2.0 protocol that allows Clients to verify the identity of users and sessions based on the authentication performed by an Authorization Server for service account permissions. KumoScale software support for OpenID Connect simplifies security integration into CSP data center environments.

KumoScale software version 3.20 also includes CSI raw block support and an embedded Grafana® storage analytics dashboard.
