Detail Specification

The HPE FlexFabric 2-Port 10GB PCIe 2.0 533FLR-T Adapter (700759-B21) is a high-performance network adapter designed for use in HPE ProLiant servers. It is based on the FlexFabric architecture and provides two 10 Gigabit Ethernet (10 GbE) ports that support Fibre Channel over Ethernet (FCoE) and iSCSI protocols.

The adapter uses a PCIe 2.0 interface and is compliant with the 533FLR-T form factor. It supports a maximum data transfer rate of 20 Gbps and is compatible with a wide range of operating systems, including Windows, Linux, and VMware.

The adapter is equipped with advanced features such as hardware offloads, jumbo frames, and flow control, which help to improve network performance and reduce CPU utilization. It also supports VLAN tagging, Quality of Service (QoS), and advanced security features such as TCP/IP checksum offload and TCP/UDP segmentation offload.

The HPE FlexFabric 2-Port 10GB PCIe 2.0 533FLR-T Adapter is designed for use in data center environments, and is ideal for use in virtualization, cloud, and high-performance computing applications. It is also suitable for use in storage area networks (SANs) and converged network environments.

Exceptional Reliability for PCI-E Adapter

The HPE FlexFabric 2-Port 10GB PCIe 2.0 533FLR-T Adapter (part number 700759-B21) is a high-performance network adapter designed for use in HPE ProLiant servers. It is built to provide exceptional reliability and performance for data center and enterprise environments.

This adapter features two 10 Gigabit Ethernet ports that use the PCIe 2.0 interface, which provides high-speed data transfer and low latency. The 533FLR-T model is specifically designed for use with Fibre Channel over Ethernet (FCoE) and iSCSI protocols, making it ideal for virtualized environments and storage area networks (SANs).

The adapter also includes advanced features such as flow control, jumbo frames, and support for virtual LANs (VLANs) to help improve network efficiency and security. Additionally, it is built with advanced error correction and fault tolerance features to help ensure data integrity and reduce the risk of network downtime.

Data Protection and Security

The HPE FlexFabric 2-Port 10GB PCIe 2.0 533FLR-T Adapter (part number 700759-B21) is a network adapter designed for use in HPE ProLiant servers. It provides two 10 Gigabit Ethernet ports, which can be used to connect the server to a high-speed network.

The adapter also has built-in data protection and security features to help ensure the integrity and confidentiality of data transmitted over the network. These features include:

  • Advanced Error Correction Code (ECC) memory: This helps prevent data corruption by detecting and correcting errors in the memory used by the adapter.
  • TCP/IP Checksum Offload: This feature offloads the task of calculating TCP/IP checksums to the adapter, reducing the load on the server's CPU and improving performance.
  • TCP/IP Segmentation Offload: This feature offloads the task of segmenting large TCP/IP packets into smaller ones to the adapter, again reducing the load on the server's CPU and improving performance.
  • Priority-based flow control: This feature allows the adapter to prioritize traffic, ensuring that important data is transmitted first and reducing the risk of data loss due to network congestion.
  • Secure Data Path: This feature provides hardware-based encryption and decryption for data transmitted over the network, helping to protect against unauthorized access or tampering.
