The devices integrate networking and processing subsystems for a wide range of data center applications including programmable NIC (or Smart NIC) for data plane acceleration and high-performance Flash storage disaggregation using NVMe-over-Fabrics (NVMe-oF).

The BCM58800 devices are fabricated in a low-power, 16nm FinFET+ process.

And the devices feature a NetXtreme E-Series advanced network controller, a high-performance ARM CPU block, PCI Express (PCIe) Gen3 interfaces, key accelerators for compute offload and a high-speed memory subsystem including L3 cache and DDR4 interfaces, all interconnected by a coherent Network-on-chip (NOC) fabric.

The network interface is powered by the latest generation of NetXtreme controller technology, delivering high packet rate and low latency.

Support for the NVMe-oF standard is enabled over RoCE (RDMA over Converged Ethernet) v1 & 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 TruFlow configurable flow accelerator adds a packet inspection and processing capability in the hardware, moving common flow-processing workloads into hardware and freeing CPUs for application workloads.

The ARM CPU subsystem features eight ARMv8 Cortex-A72 CPUs at 3.0 GHz, arranged in a multi-cluster configuration.

The BCM58800 Ethernet interface uses a multi-rate SerDes PHY that is common to Broadcom switch silicon, featuring 4-lane 25 Gb/s transceivers to support various configurations up to 100 Gb/s and subset configurations up to four channels.

The interface supports direct connection of optical modules or DAC (direct-attach copper) cables without requiring an external PHY.

A variety of interfaces are included for boot and OS code, journaling and similar usage, including up to 8 SATA3 ports, eMMC/SDIO, 1 Gb Ethernet, USB 3.0 and 2.0, SPI, QSPI, and NAND flash. Other common interfaces include NC-SI, JTAG, UART, BSC, MDIO and GPIOs.
