KIOXIA Announces Production Availability of Native Ethernet Flash-Based SSDs

EM6 Series Enables New Use Cases for NVMe-oF Applications

SAN JOSE, CA, November 11, 2021 – KIOXIA America, Inc. today announced the production availability of its EM6 Series Enterprise NVMe-oF™ solid state drives (SSDs) for Ethernet Bunch of Flash (EBOF) systems. Using the Marvell® 88SN2400 NVMe-oF SSD converter controller that converts an NVMe® SSD into a dual-ported 25Gb NVMe-oF SSD, KIOXIA EM6 Series drives expose the entire SSD bandwidth to the network.

Due to their ability to scale performance of NVMe SSDs, native NVMe-oF architectures are well-suited for applications such as artificial intelligence (AI)/machine learning (ML), high performance computing (HPC) and storage expansion. In the case of HPC, leveraging the Lustre® file system, which is used to provide high bandwidth and parallel access to compute clusters, is beneficial to NVMe-oF based storage, such as EBOF systems with EM6 SSDs, that enable high availability (HA) configurations.  An HPC HA configuration example consists of multiple and redundant network connections between a compute host and an EBOF with 88SN2400-connected NVMe SSDs, to deliver scalable throughput based on the number of SSDs.

In an HA disaggregated block storage expansion use case, the same configuration could accommodate multiple host systems, providing shared and scalable block storage with high bandwidth utilization of the NVMe SSDs.

KIOXIA EM6 Series drives have successfully undergone NVIDIA® GPUDirect Storage® (GDS) certification testing.  GDS connects to NVIDIA A100-based systems to accelerate AI/ML applications, and EBOF storage platforms enable scaling of NVMe flash storage for these storage-hungry workloads.

EM6 Series Key Features

  • Single or dual 25Gb Ethernet and RoCEv2 network connectivity
  • NVMe-oF 1.1 and NVMe 1.4 specification compliant
  • 2.5-inch 15mm Z-height form factor
  • 1 DWPD endurance with 3,840 GB, 7,680 GB capacity options


KIOXIA EM6 Series drives are available now through Ingrasys – a subsidiary of Foxconn, in its ES2000 EBOF platformAbra em uma nova janela.. ES2000 is a 2U storage system that holds up to 24 2.5-inch form factor drives and can be configured with multiple network connections for increased throughput and redundancy.

Definition of capacity: KIOXIA Corporation defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1Gb = 2^30 bits = 1,073,741,824 bits, 1GB = 2^30 bytes = 1,073,741,824 bytes and 1TB = 2^40 bytes = 1,099,511,627,776 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
