In addition to its speed, the BCM57608 series (datasheet linked) includes modern features that allow it to withstand data-center-grade network loads. Chief among these are remote DMA (RDMA) and RDMA-over-converged Ethernet (RoCE), which allow temporary spikes in data input to be mitigated without requiring software intervention. As a result, BCM57608-based Ethernet adapters offer greater performance in situations where congestion and contention are common.
The BCM57608 is available in PCIe- and OCP-NIC form factors with single- and dual-port options. These adapters are designed to be vendor-agnostic, allowing designers to use the NICs with a wide range of supporting hardware.
Modern Processes for Modern Solutions
Although modern processors (such as NPUs) and memory have evolved to better deal with the vast volume of AI data, designers still cannot reasonably store all training data on a single machine. Networking plays a critical role in modern high-performance computing, where many collocated computers work in tandem.
