Description
The #HPE Synergy 4820C is a state-of-the-art dual-port mezzanine card designed to revolutionize the networking capabilities of your #blade server infrastructure. Operating at flexible speeds of 10Gb, 20Gb, or 25Gb, this #converged network adapter provides the high-bandwidth and low-latency connectivity required for modern, data-intensive applications. As a critical component of the HPE Synergy Composable Infrastructure, the #876449-B21 allows IT administrators to dynamically allocate network resources to meet fluctuating workload demands.
Built upon the robust #Marvell FastLinQ 41000 series controller, the #876449-B21 delivers exceptional performance for virtualized environments. It significantly reduces CPU overhead by offloading protocol processing for tunneling technologies like VXLAN, NVGRE, and Geneve. This efficiency makes it an ideal choice for a #dedicated server hosting private clouds or large-scale container deployments. When you #buy server hardware of this caliber, you are investing in a future-proof #server system that can handle the transition from 10G to 25G networking seamlessly.
The #HPE Synergy 4820C is not just a standard NIC; it is a true converged solution. It supports a wide array of storage protocols including iSCSI and FCoE, allowing for the consolidation of network and storage traffic over a single wire. This convergence simplifies cable management within the #hpe server frame and reduces overall hardware costs. For organizations looking for a #server on sale that doesn't compromise on I/O flexibility, the Synergy 4820C represents the pinnacle of mezzanine-level engineering.
In addition to raw speed, the #876449-B21 prioritizes data integrity and security. It features hardware-level support for RoCE (RDMA over Converged Ethernet) versions 1 and 2, which facilitates direct memory access between servers with minimal latency. This is particularly beneficial for high-frequency trading and high-performance computing (HPC) clusters. Given the competitive #server price for these premium #server parts, upgrading your Synergy compute modules with the 4820C adapter ensures maximum return on investment through improved throughput and reduced operational complexity.
Finally, the integration of the #876449-B21 into the HPE OneView management ecosystem allows for automated provisioning and firmware updates. This seamless management reduces the risk of configuration errors and ensures that your #blade server fleet is always running at peak performance. Whether you are managing a localized #dedicated server or a global fleet of #hpe server frames, the Synergy 4820C provides the reliability and agility needed for the modern digital enterprise.

Compatibility
The #876449-B21 is purpose-built for the HPE Synergy ecosystem. It is compatible with a wide range of Synergy Compute Modules, including the HPE Synergy 480 Gen10 and Gen11, as well as the HPE Synergy 660 Gen10 models. It must be installed in a mezzanine slot that corresponds to a Synergy Fabric capable of supporting 10/20/25Gb speeds, such as the HPE Synergy 12000 Frame with appropriate interconnect modules like the HPE Virtual Connect SE 100Gb F32 Module. This #hpe server adapter ensures consistent performance across various #blade server generations within the same composable frame.
Usage Scenarios
The primary #Usage Scenarios for the #HPE Synergy 4820C involve High-Density Virtualization. In environments running VMware ESXi or Microsoft Hyper-V, the ability to offload network encapsulation tasks like VXLAN allows for higher VM density per #blade server. This directly impacts the total cost of ownership by allowing organizations to do more with less physical #server parts while maintaining high-speed network access for every virtual instance.
For High-Performance Computing (HPC) and scientific research, the #876449-B21 is indispensable. Its support for RoCE ensures that large datasets can be shared between compute nodes in a #dedicated server cluster with near-zero latency. This is critical for simulations, financial modeling, and AI training where the speed of data movement is often the primary bottleneck in the #server system.
In Enterprise Storage Area Networks (SAN), the converged nature of the 4820C allows it to replace multiple specialized adapters. By running iSCSI or FCoE alongside standard Ethernet traffic, IT teams can simplify their fabric architecture. This consolidation is particularly useful for growing businesses that want to #buy server hardware that can act as both a compute node and a high-speed storage initiator without adding physical complexity to the #hpe server frame.
The #HPE Synergy 4820C is also an excellent choice for Telco and Service Provider clouds. With support for Data Center Bridging (DCB) and high-throughput 25Gb links, it provides the deterministic performance required for Network Functions Virtualization (NFV). Service providers looking for a #server on sale with high I/O throughput will find the 4820C to be a robust solution for hosting everything from edge computing nodes to core 5G networking services.
Lastly, Content Delivery Networks (CDN) and high-traffic web hosting benefit from the massive bandwidth of the 25Gb interface. The #876449-B21 ensures that media assets and web content can be served to thousands of concurrent users without local #server parts becoming a congestion point. When evaluating the #server price, the increased throughput often allows for a reduction in the total number of servers required to handle peak traffic loads.
Frequently Asked Questions
Q1: Does the HPE Synergy 4820C support 10Gb networking if my fabric is not yet 25Gb?
A1: Yes, the #876449-B21 is designed with backward compatibility in mind. It can operate at 10Gb or 20Gb speeds depending on the interconnect modules and transceivers used within the HPE Synergy frame, providing a smooth migration path to 25Gb when your infrastructure is ready.
Q2: What is the benefit of using a Converged Network Adapter (CNA) over a standard NIC?
A2: A #converged network adapter like the Synergy 4820C allows you to run both LAN (Ethernet) and SAN (iSCSI/FCoE) traffic over the same physical hardware. This reduces the number of mezzanine cards and cables needed in your #blade server, lowering power consumption and cooling requirements in the datacenter.
Q3: How does RoCE v2 benefit my dedicated server cluster?
A3: RoCE v2 (RDMA over Converged Ethernet) allows for high-speed data transfer between a #dedicated server and its peers at the memory level, bypassing the traditional TCP/IP stack. This significantly reduces latency and CPU load, which is essential for distributed databases, big data analytics, and real-time trading applications.
Q4: Is the Marvell FastLinQ 41264 controller compatible with major operating systems?
A4: Absolutely. The #Marvell FastLinQ controller used in the 4820C has extensive driver support for VMware ESXi, Microsoft Windows Server, and major Linux distributions such as RHEL and SLES, ensuring seamless integration into your existing #hpe server software stack.
