Description
Overview of the 874795-B21 Adapter
The 874795-B21 HPE Xl1x0r Gen10 Network Adapter is a network interface card (NIC) designed and manufactured by Hewlett Packard Enterprise (HPE). This adapter is designed to provide high-speed network connectivity to servers and workstations in enterprise environments. In this article, we will provide a detailed overview of the 874795-B21 HPE Xl1x0r Gen10 Network Adapter, including its features, benefits, and specifications.
Features
The 874795-B21 HPE Xl1x0r Gen10 Network Adapter is a PCIe 3.0 x8 network adapter that provides 10/25/40/50/100Gb Ethernet connectivity. It is compatible with Gen10 HPE ProLiant DL/ML/SL servers, HPE Synergy Gen10 compute modules, and HPE Apollo 4200 Gen10 servers.
The adapter features RDMA over Converged Ethernet (RoCE) v2 support, which enables low-latency and high-bandwidth network connectivity. RoCE is an industry-standard protocol that enables efficient data transfer between servers and storage devices.
The adapter also features iSER (iSCSI Extension for RDMA) support, which provides high-performance block storage access over Ethernet networks. This feature allows servers to access remote storage devices with low latency and high bandwidth, which is ideal for applications that require high-speed data access.
The 874795-B21 HPE Xl1x0r Gen10 Network Adapter also supports Virtual Extensible LAN (VXLAN) and Generic Routing Encapsulation (GRE) tunneling protocols. VXLAN is a network virtualization technology that enables the creation of logical networks over physical networks, while GRE is a tunneling protocol that encapsulates packets in IP packets for transport across the Internet.
Benefits
The 874795-B21 HPE Xl1x0r Gen10 Network Adapter provides several benefits to enterprise environments. First, it provides high-speed network connectivity, which is essential for modern applications that require fast data transfer rates. With support for multiple Ethernet speeds, the adapter can adapt to different network environments and meet the bandwidth requirements of different applications.
The adapter’s RoCE support enables low-latency and high-bandwidth network connectivity, which is ideal for applications that require real-time data transfer. For example, applications that process large amounts of data in real-time, such as financial trading systems or scientific simulations, can benefit from RoCE support.
The adapter’s iSER support provides high-performance block storage access over Ethernet networks, which is ideal for enterprise storage environments. With iSER support, servers can access remote storage devices with low latency and high bandwidth, which improves application performance and reduces storage costs.
The adapter’s VXLAN and GRE support enables network virtualization and tunneling, which is essential for modern data center environments. With these protocols, administrators can create logical networks over physical networks, which improves network scalability and simplifies network management.
