The HPE Dual-Ports 25Gbps 640FLR-SFP28 Network Adapter with part number 817750-B21 provides high performance and throughput, making it an ideal choice for demanding workloads and applications.
The adapter supports 25 Gbps Ethernet speeds, which provides faster data transfer rates compared to traditional 10 Gbps Ethernet networks. This higher speed can help reduce latency and improve application response times, resulting in better overall performance.
In addition, the adapter supports Remote Direct Memory Access (RDMA) technology, which enables direct memory access between servers and storage devices without involving the host CPU. This reduces CPU overhead and improves network performance, particularly in high-bandwidth, low-latency applications like High Performance Computing (HPC) and Big Data analytics.
The adapter also supports Virtual Machine Device Queues (VMDq) and Single Root I/O Virtualization (SR-IOV) technologies, which help to improve network throughput and reduce latency in virtualized environments.
Furthermore, the adapter includes hardware offloading capabilities for key networking functions, such as TCP/IP checksum offloading and Large Send Offload (LSO), which can help to reduce CPU utilization and improve overall network performance.
The HPE Dual-Ports 25Gbps 640FLR-SFP28 Network Adapter with part number 817750-B21 provides high performance and throughput, making it an excellent choice for organizations that require high-speed networking for demanding workloads and applications.
Network Virtualization with the HPE Ethernet AdapterThe HPE Dual-Ports 25Gbps 640FLR-SFP28 Network Adapter with part number 817750-B21 supports network virtualization, which is the ability to create multiple virtual networks on top of a physical network infrastructure. Network virtualization provides several benefits, including increased flexibility, scalability, and security.
The adapter supports Single Root I/O Virtualization (SR-IOV) technology, which allows the adapter's physical functions to be shared by multiple Virtual Machines (VMs) simultaneously, each with their own virtualized network interface card (NIC). This enables VMs to bypass the hypervisor and communicate directly with the adapter, improving network performance and reducing latency.
In addition, the adapter supports Virtual Extensible LAN (VXLAN) technology, which allows for the creation of virtual Layer 2 networks on top of an existing physical network. VXLAN provides greater scalability by enabling the creation of up to 16 million unique virtual network identifiers (VNIDs), which can be used to isolate traffic between different virtual networks.
The adapter also supports Network Virtualization using Generic Routing Encapsulation (NVGRE), which is similar to VXLAN in that it allows for the creation of virtual Layer 2 networks on top of an existing physical network. However, NVGRE uses a different encapsulation protocol than VXLAN and supports up to 16 million unique Virtual Subnet IDs (VSIDs).
The HPE Dual-Ports 25Gbps 640FLR-SFP28 Network Adapter with part number 817750-B21 provides support for network virtualization, enabling organizations to create multiple virtual networks on top of a physical network infrastructure. This can provide increased flexibility, scalability, and security, making it an ideal choice for organizations with virtualized environments.
Fast Data Transfer SpeedsThe HPE Dual-Ports 25Gbps 640FLR-SFP28 Network Adapter with part number 817750-B21 provides fast data transfer speeds, making it an ideal choice for organizations that require high-speed networking for demanding workloads and applications.
The adapter supports 25 Gbps Ethernet speeds, which is significantly faster than traditional 1 Gbps or 10 Gbps Ethernet networks. This higher speed can help reduce latency and improve application response times, resulting in better overall performance.
In addition, the adapter supports Remote Direct Memory Access (RDMA) technology, which enables direct memory access between servers and storage devices without involving the host CPU. This reduces CPU overhead and improves network performance, particularly in high-bandwidth, low-latency applications like High Performance Computing (HPC) and Big Data analytics.
The adapter also supports hardware offloading capabilities for key networking functions, such as TCP/IP checksum offloading and Large Send Offload (LSO), which can help to reduce CPU utilization and improve overall network performance.
Furthermore, the adapter includes support for Receive Side Scaling (RSS), which distributes incoming network traffic across multiple processor cores, enabling better utilization of available processing power and improving network performance.
The HPE Dual-Ports 25Gbps 640FLR-SFP28 Network Adapter with part number 817750-B21 provides fast data transfer speeds and performance-enhancing features, making it an excellent choice for organizations that require high-speed networking for demanding workloads and applications.
