Featured Products

OpenFlex Composable Infrastructure

  • Composable Infrastructure. Physical resources can be organized, accessed and managed with a common interface and open API.
  • Scalable. Provides independent scalability of compute and storage resources to maximize efficiency.
  • Disaggregated. Physical disaggregation of compute, network and storage resource pools that can be then composed for use by application workloads.
  • Extensible. Flash, disk and future composable entities can be managed and shared over the same fabric using the same APIs.

With the exponential growth in data, along with the increasing diversity of workflows and demands on IT infrastructure, businesses need to increase speed, agility and time-to-value for their customers. Emerging as a solution for this, composable infrastructure is a new architectural approach that – using NVMe™-over-Fabric – will vastly improve compute and storage utilization, performance, and agility in the data center.

Built on industry standard NVMf technology, Western Digital’s OpenFlex architecture creates independently scalable pools of flash and disk that can be connected to computing resources via common networking technologies, such as Ethernet. Western Digital’s new Kingfish API enables the flash and disk pools to be presented as software composable infrastructure that can be quickly and easily orchestrated into logical application servers. When compared to hyperconverged infrastructure (HCIs), which has fixed ratios of compute, storage and networking, the OpenFlex architecture and products can reduce total cost of ownership by up to 40 percent by eliminating underutilized resources.

OpenFlex TCO

The fine-grain scalability of OpenFlex can also reduce initial infrastructure investment by nearly 50 percent. Additionally, with the disaggregated resources being directly connected, application performance can be more predictable since the logical servers are less susceptible to “noisy neighbor” workloads that compete for the same resources or data paths.

Western Digital’s Phil Bullinger, SVP of Data Center Systems, and Dave Tang, SVP of Corporate Marketing, on the OpenFlex™ Architecture, explain why OpenFlex is such an important architectural advance in this video.


Western Digital’s family of OpenFlex fabric-attached products are now available in a variety of performance levels and capacities to enable data center architects and IT managers to purpose-build a scalable and flexible data center for their unique needs.

Products include:

  • OpenFlex™ F3000* Series Fabric Device: For performance intensive Fast Data applications. Available in capacities up to 61TB4, it delivers low-latency NVMe flash performance over two 50Gb5 Ethernet ports.
  • OpenFlex ™ E3000 Series Fabric Enclosure: A 3U enclosure that houses up to ten hot swappable F3000 fabric devices.

OpenFlex E3000

  • OpenFlex™ D3000* Series Fabric Device: For capacity intensive Big Data applications. The 1U device offers up to 168TB of hard disk capacity over two 25Gb Ethernet ports.

OpenFlex D3000

* OpenFlex F3000 and OpenFlex D3000 can be hot-plugged to and from the network.

Plus, OpenFlex delivers:
  • Composable, shareable high-performance storage.
  • Data access from anywhere in the data center.
  • Lower CapEx and OpEx by reducing resource over provisioning.
  • Manageability through existing data center orchestration frameworks.
  • Common hardware for almost any use case.
  • Reduced stranded or underutilized resources.
  • Dynamic provisioning (scale down resources just as easily as you scale up).
  • Scale at the enclosure or blade level for a wide range of use cases.
  • Up to 205TB/U of flash-based storage; up to 168TB/U of disk-based storage.
The Future of Data Infrastructure: Western Digital’s Software Composable Infrastructure

In this highly informative Technology Brief, Western Digital provides insights into the architectural shifts underway to ensure that performance, scale and efficiency can be quickly and easily provisioned and optimized for the most demanding data environments. Through the convergence of emerging technologies, open standards, innovation and a growing ecosystem, the future is in composable infrastructures.

At the August 2018 Flash Memory Summit, Phil Bullinger, Western Digital SVP and General Manager of Data Center Systems, delivered the Keynote Address.

Ultrastar Serv60+8

A hybrid storage server that balances high density and performance with low cost for demanding workloads in Software-Defined Storage (SDS) environments, the Ultrastar Serv60+8 addresses the demanding needs of large enterprise customers, OEMs, cloud service providers, and resellers/integrators that require dense, shared HDD or hybrid storage with compute included. The Ultrastar® Serv60+8 hybrid storage server offers a choice of CPUs, memory, and drives, providing the flexibility to balance capacity, performance and cost.

Ultrastar serv60+8

  • High Density – Up to 60 HGST HelioSeal® HDDs providing up to 780TB of raw storage in a 4U enclosure
  • Hybrid – Support for up to 32 SSDs within the server for data acceleration
  • Innovative – Patented IsoVibe™ and ArcticFlow™ technologies improve reliability and reduce power costs

Ultrastar Data102

The Ultrastar Data102 is a key element of next-generation disaggregated storage and software-defined storage (SDS) systems, delivering extreme density and the flexibility to balance performance with cost. The Ultrastar Data102 provides up to 1.2PB of raw storage in a compact and efficient form factor. HGST HelioSeal® drives ensure cool running, quiet operation and high reliability. A high performance data tier can be set up for demanding applications by using SSDs in up to 24 of the drive slots. Additionally, it features two new technologies: Arctic Flow and IsoVibe. IsoVibe reduces vibration-induced performance degradation, while ArcticFlow overcomes the cooling issues by introducing cool air into the middle of the platform. Both these technologies contribute to long-term reliability, enabling our five-year limited warranty on the entire platform.

Ultrastar Data102
