Kioxia KumoScale V3.11 Software With NVMe-oF Includes Cross-Domain Volume Replication

Kioxia America, Inc.(formerly Toshiba Memory America, Inc.), U.S.-based subsidiary of Kioxia Corporation, announced that the v3.11 of its KumoScale storage software with NVMe-oF includes cross-domain volume replication.

With this feature, KumoScale offers data protection at the storage layer while maintaining NVMe flash performance and low latency.

KumoScale storage software makes flash storage accessible over a data center network – allowing data centers to run more efficiently. To address the inefficiencies associated with DAS architectures, this software disaggregates performance NVMe SSDs from compute nodes and shares them across a network infrastructure as network-attached resources.

Many databases and applications require their storage systems to provide resilience vs. drive failure and across arbitrary failure domains. These domains can include racks, aisles – or entire data centers. KumoScale software’s cross-domain replication makes data protection available and easy to flexibly deploy.

The software’s data center-level approach to resilience vs. drive failure or network partition allows users to specify arbitrary failure domains using tags. When provisioning volumes, tit will create volume replicas across multiple KumoScale appliances located in different failure domains for rack-level resiliency. This addresses both equipment failure and maintenance downtime scenarios, and can be provided to only those applications or storage classes that require it.

“Cloud-native applications typically offer data protection by replicating shards at the database layer,” noted Joel Dedrick, VP and GM, networked storage software, Kioxia America. “However, in our experience, few customers are 100% cloud native – there are always a few legacy applications that depend on the storage layer to provide data protection. KumoScale software’s cross-domain volume replication is designed to provide the flexibility to protect data for entrenched applications while not forcing a one-size-fits-all solution across a company’s workloads.“

The company designed KumoScale software to deliver NVMe flash as a service – enabling cost-effective, networked flash performance close to that of local (in-server) NVMe SSDs.
