Western Digital: Next-Gen Data Infrastructures Designed Around Ultrastar NVMe SSDs and Supercharged by NVMe-oF

Western Digital Corp. (WDC) announced solutions that provide the foundation for next-gen data infrastructures designed around Ultrastar NVMe SSDs and supercharged by NVMe-oF.

Ultrastar DC SN840 Data Center NVMe SSD

Building upon the company’s design and integration capabilities – from NAND flash to storage platforms – the new dual-port, performance Ultrastar DC SN840 NVMe SSDs and in-house RapidFlex NVMe-oF controllers are standalone solutions that combine to create the OpenFlex Data24 NVMe-oF storage platform, a shared storage JBOF (Just a Bunch of Flash) enclosure that extends the value of NVMe to multiple hosts over a low-latency Ethernet fabric network. These new solutions further expand the company’s data center portfolio to help customers transition to higher efficiency NVMe SSDs and more advanced shared storage architectures to meet the evolving demands of performance-driven applications and workloads.

In today’s global digital economy, microseconds count. As hyperscale cloud and enterprise data centers constantly work to remove bottlenecks to ensure uncompromised performance and availability of essential applications, while also keeping pace with data growth, customer adoption of NVMe and NVMe-oF solutions continues to accelerate. Industry analyst firm IDC expects hyperscalers, OEMs and end-user IT organizations to continue to transition away from legacy SATA and SAS interfaces, with NVMe on track to reach more than 55% of total enterprise SSD units shipped in 2020 and grow at a 2018-2023 CAGR of 38% ⁽¹⁾.

“The future of flash is undoubtedly NVMe as it’s all about speed, efficiency, capacity and cost-effective scalability, and NVMe-oF takes it to the next level,” said Jeff Janukowicz, research VP, IDC. “Many high-performance applications have quickly become mainstay drivers of key business functions and we can expect this to further expand NVMe in data centers for global enterprises. With Western Digital’s long history of NAND flash innovation and an integrated portfolio of NVMe SSDs and new data fabrics solutions, the company is well positioned to help customers fully embrace NVMe and get the most out of their storage assets.“

Extending the company’s leadership in dual-port architecture, the performance Ultrastar DC SN840 Gen3.1 NVMe SSD is the firm’s third-gen solution with a vertically integrated in-house NVMe controller, firmware and 96-layer 3D TLC NAND technology. The Ultrastar NVMe SSD enables enterprise customers to transition from SATA and SAS to NVMe-delivering competitive performance of up to 780,000/250,000 random R/W IO/s and capacities up to 15.36TB in a drop-in U.2 15mm form factor. Its set of enterprise features includes one and 3 DW/D endurance levels, power-loss protection and TCG encryption. Future-ready, it is the solution for a growing number of mission-critical applications that require superior R/W and mixed workload performance, low latency and dual-port HA-everything from HPC, cloud computing, SQL/NoSQL databases, virtualization (VMs/containers), AI/ML and data analytics.

“Being the leader in high performance storage for AI and big data, DDN needs to stay at the leading edge of storage technologies,” said Paul Bloch, president and co-founder, DataDirect Networks, Inc. “We are fortunate to have an innovative partner like Western Digital to deliver NVMe-based all-flash solutions that maximize device performance so we can deliver application acceleration to our customers. We look forward to implementing the Ultrastar DC SN840 NVMe SSD in our solutions.“

OpenFlex Data24 NVMe-oF storage platform

While NVMe flash-based storage provides performance gains for DAS, SAN and NAS, traditional data center infrastructure can limit the potential of NVMe SSDs, resulting in under utilization of valuable storage resources, inefficient data silos and costly operational expenses. OpenFlex Data24 helps address these challenges by enabling the full bandwidth of Ultrastar NVMe SSDs to be shared by multiple hosts over a low-latency Ethernet fabric as if they were locally attached to the PCIe bus inside x86 servers. This provides flexibility for data center operators to scale-up capacity and more efficiently utilize disaggregated flash storage to achieve greater performance for demanding workloads.

Launching with up to 24 hot-swappable Ultrastar DC SN840 NVMe SSDs, OpenFlex Data24 provides shared storage capacity of up to 368TB in a 2U form factor, making it for server storage expansion and scale-out SDS environments. The holistic design also incorporates branded RapidFlex RDMA-enabled NVMe-oF controllers for network connectivity and low power, allowing up to 6 hosts to be directly attached with 100GE without the need for an external switch. RapidFlex controllers provide sub-500 nanosecond latency for projected platform performance topping 13 million IO/s/70GB/s when adding up to 6 network adapters to the OpenFlex Data24.

Built for HA and enterprise reliability, the OpenFlex Data24 can be attached as shared storage in high-performance infrastructure deployments or utilized as a disaggregated resource to compose virtual storage systems. The platform is interoperable with the OpenFlex F-series – an open composable disaggregated infrastructure (CDI) solution.

“Data infrastructure has never been as vital to the world’s economy as it is today,” said Yusuf Jamal, SVP, devices and platforms business, Western Digital. “As a leading provider of essential data infrastructure, our mission is to help enterprises architect next-gen data centers to support business-critical applications and bandwidth-hungry workloads at scale. Western Digital’s leadership in NAND flash, capacity-enterprise HDDs and supporting technologies are being relied upon now more than ever. We’re fully committed to helping companies transition to NVMe and move to new composable architectures that can maximize the value of their storage resources.“

Shipments for the Ultrastar DC SN840 NVMe SSD will begin next month and the OpenFlex Data24 NVMe-oF storage platform is scheduled to ship in the Fall with a 5-year limited warranty. RapidFlex NVMe-oF controllers are available.
