The adapter is available in green and grey colors, making it suitable for various server environments. With model number 647586-B21-RFB, it provides efficient data transfer and enhances network capabilities for HP Enterprise systems.

## Long description

The HP FlexFabric 10Gb 2-port 554FLB adapter integrates Ethernet and Fibre Channel (FC) functionality in a Flexible LOM form factor for the HP BladeSystem c-Class Gen8 platform. It accelerates and offloads stateless TCP/IP, TCP Offload Engine (TOE) and Fibre Channel processing to optimize both network and storage traffic, and supports Virtual Connect Flex-10 to increase bandwidth for virtualized servers.
Advantages
The adapter provides a unified platform for network and storage connectivity, reducing the need for separate host bus adapters. Hardware acceleration and multiple protocol offloads improve server efficiency and lower CPU utilization. The design delivers competitive performance per watt to help reduce power consumption, and it is engineered for straightforward deployment and management. Converged networking simplifies infrastructure and can reduce capital and operating expenses.
Key specifications
 Form factor: Flexible LOM for HP BladeSystem c-Class Gen8
 Ports: 2 × 10Gb
 Protocols: Ethernet and Fibre Channel (FC)
 Offloads: Stateless TCP/IP, TCP Offload Engine (TOE), Fibre Channel offload
 Virtualization support: Virtual Connect Flex-10
How to use
Install the HP FlexFabric 554FLB into the Flexible LOM slot of a compatible HP BladeSystem c-Class Gen8 server following HP installation guidelines. Configure network and storage zoning as required, enable Virtual Connect Flex-10 in the Virtual Connect Manager if using virtualization features, and verify firmware and driver compatibility with the server OS. Monitor performance and adjust offload settings according to workload needs.
Recommendations
Use this adapter in HP BladeSystem c-Class Gen8 environments where converged network and storage connectivity is required. Ensure current firmware and drivers are applied and that Virtual Connect modules are configured to take advantage of Flex-10 capabilities.
