Broadcom 100GbE NVMeOF PCIe storage (NVMe-Over-Fabric)

Published by


Broadcom released their Stingray PS1100R storage controller platform, enabling fast development and delivery of storage services and Ethernet fabric-attached Flash solutions. The PS1100R can be used to deliver a range of storage solutions, from high-performance Flash arrays to block/object storage, along with software-based storage services.

The Stingray BCM58804H data center SoC, which combines Broadcom’s NetXtreme® 100GbE networking core with ARM processor subsystems with hardware acceleration for key workloads, forms the foundation of the PS1100R platform. Fabricated in 16nm FF+ process, the Stingray SoC enables industry leading integration and ARM CPU performance in a compact, low-power package. The PCIe form-factor eases chassis development and enables modular storage solution designs.
The latest generation integrated 100Gb NetXtreme Ethernet NIC provides high packet rates, low latency and a complement of network acceleration functions for the modern data center. The powerful TruFlow™ configurable flow accelerator adds a powerful packet inspection and processing capability in the hardware, moving common flow-processing workloads into hardware and freeing CPUs for application workloads. Support for the NVMe-oF standard is enabled over RoCE (RDMA over Converged Ethernet) v1 and v2, as well as over TCP and other transports, ensuring a future-proof and scalable platform for the deployment of disaggregated storage over a range of topologies.
The Stingray family of products is supported by a comprehensive Software Development Kit providing a complete turnkey Linux distribution, and the open programming model enables porting of applications with minimal effort. The platform uses standard Linux and standard GNU tools and libraries. All drivers for the Stingray SoC are upstreamed to, and all peripheral interfaces use standard device drivers. 
In addition to the Linux kernel NVMe-oF data path, the Stingray SDK also supports the industry-standard user space Storage Performance Development Kit (SPDK) to enable maximum I/O performance.
