Western Digital introduced new OpenFlex™ Data24 NVMe-oF™ Storage Platform

Western Digital (NASDAQ: WDC) announced new solutions that provide the foundation for next-generation data infrastructures designed around Ultrastar NVMe™ SSDs and supercharged by NVMe-oF™. Building upon the company's innovative 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 new OpenFlex Data24 NVMe-oF Storage Platform, a new 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 Western Digital'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.

Key features of new product: 

• High density - up to 368TB in 2U
• Low latency
• Balanced bandwidth between SSDs and Network
• RESTful API based support for management
• High availability with dual IO Modules
• 3x Western Digital RDMA enabled NVMe-oF adapters per IOM
–       Up to six 100GbE ports with dual IOM at full performance
• Short chassis depth 28”(711mm) – fits most common racks
• Industry leading 5-year limited warranty
• 24 Dual port high-performance SSDs – Next Generation SN840
• Wide range of NVMe SSD capacity and endurance options
• SN840: 1 DWPD: Up to 15360 GB
• SN840: 3 DWPD: Up to 6400 GB
• High availability with dual IOM
• OpenFlex inspired composability in a mainstream 2U24
• 28”(711mm) chassis depth – fits most commonly used short depth racks (800-1000 mm)
   

Up to 24 Ultrastar® DC SN840 NVMe SSDs

Up to 6 RapidFlex™ NVMe-oF Network Adapters

Main capabilities:

• Enterprise design

–Dual “Fabric IOMs” for HA implementation

–Support for hot plug and surprise removal

–N+1 redundant, CRPS hot-swappable power

–N+1 redundant cooling

–Supports high-performance dual port drives

–Balanced design maximizes throughput and minimizes latency through matching lane count

–Chassis supports up to 25W power per drive slot

• Manageability

–RESTful based API for In-Band and Out-of-Band enclosure management

–Open Composable API support

–nvme-cli command based enclosure management*

• Power and management

–Individual power control and resets to each drive

–Power Isolation

—fault on one drive will not affect power on others

–OOB I2C interface to each drive

–Enclosure Manager (EM) for chassis

–Conformance to NVM Express® MI 1.0 specification 

Main advantage that NVMe-oF supports significantly higher performance-intensive workloads:

Enables servers to share NVMe flash storage as if it were local

Provides industry-leading connectivity options using 100Gb Ethernet

Disaggregates NVMe storage for open composability
