Samsung Electronics and Western Digital (Nasdaq: WDC) today announced that they have signed a memorandum of understanding (MOU) for a unique collaboration to standardize and drive broad adoption of next-generation data placement, processing and fabrics (D2PF) storage technologies. The companies will initially focus on aligning their efforts and creating a vigorous ecosystem for Zoned Storage solutions. These steps will enable the industry to focus on countless applications that ultimately create greater value for customers.

This marks the first time that both Samsung and Western Digital have come together as technology leaders to create widespread alignment and stimulate awareness for important storage technologies. Focusing on enterprise and cloud applications, the partnership is expected to spur a range of collaborations around technology standardization and software development for D2PF technologies like Zoned Storage. With this collaboration, end-users can have confidence that these emerging storage technologies will have support from multiple device vendors as well as from vertically integrated hardware and software companies.

“Storage is the essential foundation for how people and businesses consume and use data. To enable today’s needs and tomorrow’s next big ideas, we must innovate, collaborate and keep pace as an industry in bringing new standards and architectures to life,” said Rob Soderbery, EVP and GM, Flash Business Unit at Western Digital. “In order for a technology ecosystem to be successful, overall frameworks and general solution models must come together so they do not suffer from fragmentation, which delays adoption and adds unnecessary complexity for software stack developers.”

Soderbery added, “For years Western Digital has been laying the foundation for the Zoned Storage ecosystem by contributing to the Linux kernel and open-source software community. We are excited to bring these contributions to this joint initiative with Samsung in facilitating wider adoption of Zoned Storage for users and application developers.”

“This collaboration is a testament to our relentless effort to exceed customers’ needs now and in the future, and holds special meaning in how we anticipate it will actively grow into a larger basis of engagement for Zoned Storage standardization,” said Jinman Han, Corporate EVP, Head of Memory Sales & Marketing at Samsung Electronics. “Our collaborative efforts will embrace hardware and software ecosystems to ensure that as many customers as possible can reap the benefits of this highly important technology.”

The two companies have already kickstarted an initiative around Zoned Storage devices, including ZNS (Zoned Namespaces) SSDs and SMR (Shingled Magnetic Recording) HDDs. Through organizations such as SNIA (Storage Networking Industry Association) and the Linux Foundation, Samsung and Western Digital will define high-level models and frameworks for next-generation Zoned Storage technologies. With a commitment to enable open and scalable data center architectures, they have founded the Zoned Storage TWG (Technical Work Group), which was approved by SNIA in December 2021. The group is already defining and specifying common use cases for Zoned Storage devices, as well as host/device architecture and programming models.

In addition, this collaboration is expected to serve as a starting point to expand zone-based (e.g. ZNS, SMR) device interfaces, as well as future-generation, high-capacity storage devices with enhanced data placement and processing technologies. At a later stage, these initiatives will be expanded to include other emerging D2PF technologies such as computational storage and storage fabrics including NVMe over Fabrics (NVMe-oF).

Samsung Electronics, the world leader in advanced memory technology, today unveiled its new enterprise solid-state drive (SSD) featuring Zoned Namespace (ZNS) technology — the PM1731a. Leveraging ZNS, the SSD will maximize available user capacity and offer an extended lifespan in storage server, data center and cloud environments.

“Samsung’s ZNS SSD reflects our commitment to introducing differentiated storage solutions that can substantially enhance the reliability and lifetime of server SSDs,” said Sangyeun Cho, senior vice president of the Memory Software Development Team at Samsung Electronics. “We plan to leverage quad-level cell (QLC) NAND technology in our next-generation ZNS drives to enable higher thresholds for storage performance and capacity in the enterprise systems of tomorrow.”

ZNS allows data to be grouped based on their usage and access frequency, and stored sequentially in independent zones within an SSD. Without the need to move and rearrange data, ZNS SSDs can significantly reduce the number of write operations, lowering the drive’s write amplification factor (WAF) — the amount of actual writes performed by the drive compared to writes initially instructed by the host system. The closer the WAF is to one, the more efficient the SSD and the longer it will last.

Based on ZNS, the new Samsung SSD can achieve a WAF close to one, a major improvement over typical server SSD values between three and four. This will make the drive last up to four times longer than conventional NVMe SSDs, making it a greener, more sustainable solution for server infrastructures. ZNS also allows users to take advantage of the SSD’s full capacity by eliminating the need for overprovisioning, which would have required reserving some storage space for background tasks. These improvements will enable enterprise customers to handle big data and artificial intelligence applications with much greater efficiency.

Built upon Samsung’s sixth-generation V-NAND, the 2.5-inch PM1731a will come in two terabyte (TB) and four TB models. The SSD will feature dual ports, ensuring the drive is fully accessible for continuous operations and minimizing downtime. This is essential for enterprises and public cloud companies who run mission-critical, data-intensive applications, and cannot afford any pause in the continuity of their businesses.

Samsung has been actively engaging in several open-source projects to help expand the ZNS ecosystem. The company will make its ZNS technology available to xNVMe, which provides software libraries and tools to improve the performance of NVMe devices. The company is also participating in the Storage Performance Development Kit (SPDK) community created by Intel, enabling SPDK users to implement ZNS more easily.

Samsung plans to mass-produce ZNS SSDs in the second half of the year and continue working with global enterprise storage companies to optimize its ZNS drives across various customer environments.
