817753-B21 HPE Ethernet 25GBPS 2 Ports 640SFP28 Network Bulk

The HPE 817753-B21 Ethernet 25GBPS 2 Ports 640SFP28 Network Adapter is a high-performance network adapter designed for use in Ethernet networks. It is a PCI Express 3.0 x8, low-profile, half-height form factor adapter that supports data transfer rates of up to 25 Gbps on each port, which is significantly faster than previous generation 10 Gbps adapters.

The adapter supports the latest SFP+ interface which is the 640SFP28 interface, designed for 25 GbE applications. This interface provides increased bandwidth and improved performance over previous SFP+ interfaces, allowing for faster data transfer and more efficient use of network resources.

The adapter also supports advanced features such as VXLAN, NVGRE, and GENEVE, which allow for network virtualization, improving network flexibility and scalability.

It is also compliant with IEEE 802.3by and 802.3bj standards, ensuring that it is compatible with a wide range of Ethernet equipment and that it meets the requirements of these standards, which are designed to ensure reliable data transfer.

The 817753-B21 also supports full duplex data transfers, which allows for simultaneous data transfer in both directions. This feature increases the data transfer rate and allows for faster data transfer, reducing the time it takes to complete data transfer tasks.

In terms of power efficiency, the adapter supports Energy Efficient Ethernet (EEE) and DMA Coalescing, which helps to reduce power consumption, making it more energy efficient.

The HPE 817753-B21 Ethernet 25GBPS 2 Ports 640SFP28 Network Adapter is designed to provide high reliability and durability for Ethernet networks.

One of the key features that contribute to its reliability is its compliance with the IEEE 802.3by and 802.3bj standards. This ensures that the adapter is compatible with a wide range of Ethernet equipment, and that it meets the requirements of these standards, which are designed to ensure reliable data transfer.

The adapter is also built to meet the demands of Ethernet networks and is designed to be hot-pluggable, allowing for easy installation and maintenance without the need to power down the server. This feature allows for easy replacement of the adapter without any disruption to the network, making it easier to maintain and update the network without interruption, ensuring that the network is always running at optimal performance.

The 817753-B21 has been tested to meet the high standards of HPE's extensive qualification process, which includes testing under extreme conditions to ensure the adapter can withstand the rigors of a data center environment, providing high-reliability and durability.

In addition, the adapter supports Energy Efficient Ethernet (EEE) and DMA Coalescing, which helps to reduce power consumption, making it more energy efficient, and reduces the stress on the adapter, prolonging its lifespan.

The HPE 817753-B21 Ethernet 25GBPS 2 Ports 640SFP28 Network Adapter is designed to be power efficient.

One of the key features that contribute to its power efficiency is its support for Energy Efficient Ethernet (EEE) and DMA Coalescing. Energy Efficient Ethernet is a set of standards that reduces the power consumption of Ethernet equipment when it is not transmitting or receiving data. DMA Coalescing is a technique that reduces the number of DMA operations required to transfer data, which in turn reduces the power consumption of the adapter.

The 817753-B21 also supports a low-power idle mode, which reduces the power consumption when the adapter is not in use.

The adapter is also built to meet the demands of Ethernet networks and is designed to be hot-pluggable, allowing for easy installation and maintenance without the need to power down the server. This feature allows for easy replacement of the adapter without any disruption to the network, making it easier to maintain and update the network without interruption, reducing the power consumption by avoiding unnecessary shut downs.

In addition, the adapter supports advanced features such as VXLAN, NVGRE, and GENEVE, which allow for network virtualization, improving network flexibility and scalability. This feature allows for easy creation of multiple virtual networks on a single physical network, improving network segmentation and security, this helps in reducing the power consumption by avoiding unnecessary traffic.
