Data creation and consumption continues to grow steadily today. According to the data International Data Corporation (IDC) for 2020, for five years – until 2023 – the compound annual growth rate (CAGR) of data acquisition, copying and consumption will be 26%. Along with the growth and sophistication of AI / IoT work ecosystems, applications and datasets, this trend is driving the need for organizations to achieve greater scalability, efficiency, performance, and responsiveness for storage systems at an optimal total cost of ownership (TCO).

NVMe ™ – current status

In a globalized digital economy, microseconds count. Maximizing the performance and availability of critical hyperscale cloud and data center applications is realized through ongoing efforts to remove bottlenecks and meet the unprecedented growing demand for data processing. Under these conditions, consumers are accelerating the adoption NVMe и NVMe over Fabrics (NVMe-oF)… Experts from industry analyst firm IDC predict that hyperscalers, OEMs and end-user organizations will continue to migrate from legacy SATA and SAS interfaces. NVMe is expected to account for more than 2020% of enterprise SSD shipments in 55, with a cumulative annual growth in NVMe shipments from 2018 to 2023 of 38%.

With a myriad of key business functions now relying on high-performance application software, more data centers around the world are adopting NVMe. Western Digital has a long history of innovation in NAND flash memory and already offers a comprehensive line of SSDs and new solutions for building data factories. Thus, Western Digital is well positioned to help customers realize the full potential of NVMe technology.

OpenFlex Data24 NVMe-oF Storage Platform

While NVMe flash drives dramatically improve the performance of DAS, SAN, and NAS storage systems, traditional datacenter architecture does not allow for the full potential of NVMe SSDs. This leads to underutilization of valuable storage resources, ineffective data segmentation, and increased operating costs.

OpenFlex Data24, the new JBOF storage system, removes these limitations by using the full bandwidth of Ultrastar NVMe SSDs at once by several compute nodes combined into an Ethernet fabric (NVMe-oF 1.0a) with low latencies so that the speed of work with JBOF comparable to the speed of a local NVMe drive connected to the server’s PCIe bus.

This approach maximizes the number of input-output operations per second (IOPS). It also provides increased flexibility to increase capacity and utilization of disaggregated flash storage to achieve greater performance in the most demanding workloads. Balanced storage architecture prevents space allocation beyond physical storage capacity (over-subscription) and provides stable NVMe performance.

Up to 24 Ultrastar DC SN24 NVMe SSDs can be installed in the OpenFlex Data840 system – in a compact 2U chassis, you can get up to 368 TB of capacity. Ideal for expanding server storage capacity or deploying scalable software-defined storage systems (SDS)… Integrated system design also includes RapidFlex NVMe-oF controllers with remote memory access (RDMA)which, with extremely low power consumption, provide excellent performance of network connections.

Up to six compute nodes can be connected over 100 Gigabit Ethernet without the need for an external switch. RapidFlex controllers have less than 500 nanoseconds of latency, delivering 13M IOPS and 70GB / s rated system performance when six NICs are installed in OpenFlex Data24.

The OpenFlex Data24 system is designed for high availability and industrial grade reliability. It can be installed as shared storage as part of a high-performance IT infrastructure, or used as a disaggregated resource in virtualized storage systems. This system is fully compatible with the award-winning F-Series OpenFlex – the world’s only solution for building open, composable, disaggregated infrastructures (CDI).
