Network adapter HP Enterprise Ethernet 10Gb 561FLR-T Dual Port, 10 Gigabit, dual-port

HP Enterprise Ethernet Adapter 10Gb 561FLR-T Dual Port is a dual‑port 10 Gigabit network adapter designed for HPE servers. It provides high‑speed Ethernet connectivity in an FLR (FlexibleLOM/FLR) compact form factor compatible with supported server slots. The adapter is intended to deliver increased bandwidth, reduced latency and improved network throughput for virtualization, storage access and clustered or converged environments. The product is identified by manufacturer part number 700699-B21-RFB and EAN 5706998859266.

Advantages

This dual‑port 10 Gigabit adapter offers consolidated network connectivity for modern server workloads while occupying a single FLR slot. The design supports high throughput and low latency for demanding tasks such as virtual machine traffic and storage I/O. As an HP Enterprise branded component it integrates with HPE server platforms and management tools, enabling easier deployment and compatibility tracking through the provided MPN and EAN identifiers.

Suitable for

• Server virtualization and hypervisor networking
• High‑performance storage access (iSCSI, NFS)
• Clustered server environments and private cloud infrastructure
• Consolidated uplinks and aggregation for top‑of‑rack or blade systems

How to use

Install the adapter into a supported HPE server FLR slot following the server hardware installation guide and standard ESD precautions. After physical installation, verify that the server firmware is at a supported level and enable the adapter in platform BIOS/UEFI if required. Install or update the appropriate HPE network driver and management software for the operating system or hypervisor in use, then configure network settings (link speed, MTU, VLANs, teaming) according to your network design. Validate connectivity and performance with standard network testing tools and monitor via server management utilities.

Recommendations

Use the adapter with supported HPE server models and keep server firmware and network drivers up to date. For best performance in virtualization and storage workloads, configure appropriate MTU sizes, enable NIC teaming or link aggregation where applicable, and separate storage and VM traffic via VLANs or dedicated physical links.
