Description
Low Latency Design and Impact on Network
Low latency refers to the time it takes for data to be transmitted between two devices in a network. In other words, it measures the delay between sending a packet of data from one device and receiving it on another device. The lower the latency, the faster the network performance.
The HPE 817762-B21 adapter is designed with a low latency architecture, which enables it to process network traffic quickly and efficiently. This can have a significant impact on network performance, particularly in data center environments where milliseconds can make a difference.
The low latency design of the HPE 817762-B21 adapter can provide the following benefits:
- Faster application response times: Applications that require real-time communication and rapid data processing, such as financial trading platforms or online gaming, can benefit from low latency networks. The HPE 817762-B21 adapter can help reduce latency, improving the responsiveness of these applications.
- Improved network throughput: Low latency networks can process more data in a shorter amount of time, resulting in improved network throughput. This can be particularly important in high-traffic data center environments where multiple applications and services are competing for network resources.
- Reduced network congestion: Low latency networks can help reduce network congestion by processing data more quickly and efficiently. This can help prevent network bottlenecks and ensure that data is delivered to its destination in a timely manner.
The low latency design of the HPE 817762-B21 adapter can have a significant impact on network performance. By reducing latency, the adapter can help improve application response times, increase network throughput, and reduce network congestion, resulting in a faster and more efficient network.
Power Efficiency and Thermal Management
Power efficiency and thermal management are important factors to consider when selecting a network adapter for use in data center environments. The HPE 817762-B21 network adapter has been designed with these considerations in mind.
Power Efficiency: The HPE 817762-B21 network adapter is designed to operate with high power efficiency, which can help reduce energy consumption and associated costs. The adapter is optimized for low power consumption, allowing it to operate with minimal power usage while still delivering high-performance networking capabilities. Additionally, the adapter supports advanced power management features, such as Energy Efficient Ethernet (EEE), which can further reduce power usage by automatically adjusting power levels based on network traffic.
Thermal Management: The HPE 817762-B21 network adapter is also designed with effective thermal management in mind. The adapter includes a number of features that help manage heat generation and dissipation, which can help ensure reliable performance and prevent thermal-related issues. These features include:
- Heat sinks: The adapter includes heat sinks that help dissipate heat away from critical components, ensuring that they remain within safe operating temperatures.
- Thermal sensors: The adapter includes built-in thermal sensors that monitor temperature levels and can adjust fan speeds as necessary to maintain safe operating temperatures.
- Adaptive fan control: The adapter supports adaptive fan control, which can help reduce fan noise and power usage by adjusting fan speeds based on temperature and workload.
The power efficiency and thermal management features of the HPE 817762-B21 network adapter can help ensure reliable performance while minimizing energy consumption and heat generation. These features make the adapter an ideal choice for data center environments where power and cooling resources are critical considerations.
Optimizing Performance and Speed
Optimizing performance and speed is a critical consideration when selecting a network adapter for data center environments. The HPE 817762-B21 network adapter is designed to deliver high-performance networking capabilities with a number of features that can help optimize speed and performance.
- 100Gbps Speed: The HPE 817762-B21 network adapter supports a high-speed connection of up to 100Gbps, allowing for fast data transfer rates and reduced latency. This can help improve overall network performance, particularly in high-traffic environments.
- PCI Express 3.0 x8 Interface: The adapter utilizes a PCI Express 3.0 x8 interface, which provides high-speed connectivity between the adapter and the server. This interface can help maximize network throughput and reduce latency, leading to improved overall network performance.
- QSFP28 Connector: The HPE 817762-B21 network adapter features a QSFP28 connector, which supports high-speed fiber optic connections. This connector can help improve network speed and performance, particularly in high-bandwidth environments.
- RDMA over Converged Ethernet (RoCE): The adapter supports RDMA over Converged Ethernet (RoCE), which can help improve network performance by reducing latency and improving throughput. RoCE enables direct memory access (DMA) transfers over Ethernet networks, resulting in faster data transfer rates and reduced CPU usage.
- Packet Acceleration: The HPE 817762-B21 network adapter supports packet acceleration, which can help improve network performance by offloading CPU-intensive network processing tasks to the adapter. This can help free up CPU resources for other tasks and reduce overall latency.
The HPE 817762-B21 network adapter is designed to optimize performance and speed, making it an ideal choice for high-performance data center environments. With features such as high-speed connectivity, a PCI Express 3.0 x8 interface, a QSFP28 connector, RoCE support, and packet acceleration, the adapter can help deliver fast, reliable network performance.
