Frequently Asked Questions
What are the primary throughput capabilities of the HPE Synergy 4820C CNA? +
The HPE Synergy 4820C is a high-performance Converged Network Adapter designed to deliver flexible bandwidth options. It supports 10Gb, 20Gb, and 25Gb Ethernet connectivity, allowing administrators to scale their network performance based on specific workload requirements within a Synergy composable infrastructure environment. This versatility ensures optimal data transfer rates for both storage and network traffic.
Which HPE Synergy compute modules are compatible with the 4820C adapter? +
This adapter is specifically engineered for use with HPE Synergy Gen10 and Gen10 Plus compute modules. By integrating directly into the mezzanine slots of these servers, the 4820C provides the essential I/O connectivity required for fabric-attached environments, enabling seamless communication between your compute nodes and the Synergy composable fabric.
How does the 876449-B21 improve storage and network traffic efficiency? +
As a Converged Network Adapter, the 876449-B21 allows for the convergence of both Ethernet and Fibre Channel traffic over a single physical connection. By utilizing this unified fabric approach, you reduce the complexity of your cabling infrastructure and minimize the number of adapters required, which leads to improved port utilization and lower overall operational overhead in the data center.
What management features are included with the HPE Synergy 4820C? +
The adapter is managed through the HPE Synergy management platform, which provides centralized control and automation. Because it is designed for a composable infrastructure, the card integrates with Synergy’s software-defined fabric management, allowing for rapid configuration, firmware updates, and monitoring of network profiles without manual intervention at the server level.
Can the 4820C adapter handle virtualized workload environments effectively? +
Yes, this CNA is optimized for virtualized environments, providing robust support for technologies such as SR-IOV and hardware-based offloads. These features reduce CPU utilization by offloading network processing tasks from the host processor, which is critical for maintaining high performance and low latency in dense virtual machine and container deployment scenarios.
What is the physical form factor of the HPE Synergy 4820C? +
The HPE Synergy 4820C is built as a mezzanine-style card. This compact, specialized form factor is designed to slide directly into the dedicated mezzanine expansion slots found on HPE Synergy compute blades. This ensures a secure, high-speed physical connection directly to the midplane of the Synergy frame, maintaining the modular architecture of the system.
Does the 4820C support RDMA for low-latency networking? +
The adapter is built to support advanced networking protocols, including RDMA over Converged Ethernet (RoCE). By utilizing RoCE, the 4820C enables direct memory access between servers, significantly reducing latency and improving throughput for high-performance computing, storage clusters, and database applications that require rapid data exchange across the network fabric.
How does this CNA ensure reliability in a mission-critical data center? +
Designed for enterprise-grade deployments, the 4820C incorporates advanced error-correction and path-redundancy features. When paired with the highly available Synergy interconnect modules, it provides a stable and resilient link for critical applications. The adapter’s integration with Synergy’s firmware management also ensures that the stack remains consistent, minimizing the risks associated with configuration drift in large-scale server farms.
