KIOXIA Outs First PCIe 4.0 OCP NVMe Cloud Specification-Enabled SSD

Today, the company expanded its broad portfolio of client, enterprise and data center SSDs with the addition of the XD6 Series. KIOXIA's E1.S form factor XD6 SSDs are the first Enterprise and Datacenter SSD Form Factor (EDSFF) E1.S SSDs.

Designed to maximize system density, efficiency and simplicity, KIOXIA's EDSFF E1.x SSDs represent the future of flash storage for servers in cloud and hyperscale data centers. As defined by the EDSFF consortium and leveraging the OCP NVMe Cloud SSD Specification, the flexible, efficient, small form factor E1.S replaces the M.2 form factor and delivers greater density, performance, reliability, and thermal management. E1.S is also designed to be hot pluggable for increased serviceability, which is another benefit over M.2

KIOXIA's XD6 Series is PCIe 4.0 and NVMe 1.3c specification compliant, and is available in E1.S 9.5 millimeter (mm), 15 mm, and 25 mm form factors. Designed for consistent performance, latency and reliability in 24x7 cloud data centers, the XD6 Series brings performance of ~2x to ~4x compared to PCIe 3.0 SSDs.

Key features include:

• Sequential read and write performance up to 6,500 megabytes per second (MB/s) and 2,400 MB/s, respectively
• 15 W power consumption
• Security options: non-SED and TCG-Opal
• Full end-to-end data path protection
• Power loss protection
• Expanded drive health information
• Excellent Quality of Service
• New KIOXIA-developed, hyperscale-optimized controller

KIOXIA is an active and contributing member to the industry development of EDSFF E1.S/L and E3.S/L solutions and is collaborating with leading server and storage system developers to unlock the full power of flash memory, NVMe and PCIe.

"Developing and deploying flash-based products is very challenging, and the OCP-based NVMe Cloud SSD Specification helps by aligning SSD providers with hyperscale needs," said Ross Stenfort, hardware storage engineer, Facebook. "EDSFF E1.S is the next generation of flash form factors, delivering superior thermals, performance, serviceability, and scalability when compared to current solutions. KIOXIA's support of EDSFF is a great step forward and lays the groundwork for the future."

"Hyperscale data centers are the heart of the internet, and the OCP platform will power future generations with SSDs optimized for server platforms," noted Neville Ichhaporia, senior director, marketing and product management, Data Center and Client SSD Division at KIOXIA America, Inc. "KIOXIA is proud to work with industry leaders on innovative storage solutions, such as our XD6 Series data center NVMe SSDs, to power their critical applications."

KIOXIA's XD6 drives are now sampling to select customers.
