727055 B21 HPE Ethernet 10Gb 2 Ports 640SFP 28 Adapter

    727055 B21 HPE Ethernet 10Gb 2 Ports 640SFP 28 Adapter

    727055 B21 is a type of HP Ethernet adapter. It has a built-in Intel® X710 controller that provides 20 Gb/s data rate per port. The bus type of PCI Express 3.0 8 GT/s x8 matches most interfaces.



    727055-B21 is the HPE Ethernet 10Gb 2-port 562SFP+ Adapter.

    The HPE Ethernet 10Gb 2-port 562SFP+ Adapter features the latest Intel controller. It is a low-cost, low-power dual port PCIe v3.0 x8 adapter designed for HPE ProLiant servers. The HPE 562SFP+ addresses the demanding needs of the next-generation data center by providing unmatched features for virtualization and scalability that complement the HPE server platform. The HPE 562SFP+ comes with both low profile and standard brackets and has two SFP+ cages that enable connections with DACs as well as SR fiber optic modules.

    The HPE 562SFP+ adapter supports SR-IOV and high performance networking features such as VLAN tagging, low latency interrupts, TCP and UDP checksum offloading, MSI-X, NIC teaming (bonding), Receive Side Scaling (RSS), jumbo frames, and PXE boot.

    Provides virtualization and scalability capabilities to complement the HPE server platform to meet the demands of next-generation data centers.

    It can be connected with DAC and SR fiber optic modules for a wider range of use.

    Faster processing with the latest generation Intel® X710 controller.
