The HPE 366FLR Network Adapter (part number 665240-B21) is a 4-port 1 Gb Ethernet adapter for the HP ProLiant server. Some of its features and benefits include:

• Flexible LOM (LAN on the motherboard) form factor: The adapter can be easily installed or removed from the server without opening the chassis, which makes it suitable for use in data center environments where serviceability is important.
• PCIe 2.1 interface: The adapter uses the PCIe 2.1 interface, which provides higher performance than earlier versions of the PCIe interface.
• Advanced software features: The adapter supports advanced software features such as TCP/IP Offload Engine (TOE), Large Send Offload (LSO) and Receive Side Scaling (RSS) to improve performance and reduce CPU utilization.
• Support for various operating systems: The adapter supports various operating systems such as Windows, Linux, and VMware.
• Low-profile and full-height bracket: The adapter comes with both low-profile and full-height brackets to allow it to be installed in a variety of server form factors.
• Quality of Service (QoS): The adapter supports Quality of Service (QoS) which is used to manage network bandwidth and optimize network performance.
• Energy Efficient Ethernet (EEE): The adapter supports Energy Efficient Ethernet (EEE) which helps to reduce power consumption during periods of low data activity.

Quality of Service (QoS) capabilities refer to the ability of a network adapter, such as the HPE 366FLR 1Gb PCIe 2.1 4 Port for ProLiant Network Adapter (665240-B21), to prioritize and manage network traffic to ensure that important or critical data is transmitted with minimal delay and interruption. This is achieved by assigning different priority levels to different types of traffic and allocating bandwidth accordingly.

The HPE 366FLR 1Gb PCIe 2.1 4 Port for ProLiant Network Adapter has several key QoS features:

• 802.1p Quality of Service (QoS) support: This allows traffic to be tagged with different priority levels so that important traffic can be given priority over less important traffic.
• Flow Control: This feature helps to prevent network congestion by allowing the network adapter to send a signal to other devices on the network to temporarily stop sending data. This allows the network adapter to catch up and prevents the network from becoming overwhelmed.
• Large Send Offload (LSO) and TCP/UDP Checksum Offload: These features help to reduce the workload on the host CPU by offloading some of the processing to the network adapter. This helps to improve overall network performance.
• Virtual Machine Device Queues (VMDq): This feature allows multiple virtual machines to share the same network adapter, while still maintaining separate queues for each VM. This helps to ensure that each VM gets the bandwidth it needs, even in a busy virtualized environment.
