Embodiment Construction

[0015] According to an aspect of the present invention, a Host Ethernet Adapter (HEA) is provided. The HEA includes multiple physical ports, for example, four RJ-45 ports that can be zoned across multiple systems. One RJ-45 port can support up to, say, 16 partitions using a single port, where each partition cannot see each other's traffic. These ports are eg 1Gbps or 10Gbps. Divide this capacity among the partitions using this physical port.

[0016] According to a feature of the invention, with the help of the HEA, the hardware of the HEA performs the virtualization, thereby eliminating the need for traditional network virtualization. Traditional network virtualization is accomplished through the use of shared Ethernet adapters managed by the host operating system (OS) along with virtual network bridging.

[0017] According to a feature of the invention, when configuring the logical ports of the HEA, a minimum guaranteed speed, and optionally a maximum speed, will be speci...

Abstract

Bandwidth capping is implemented at a logical port level for a shared Ethernet port. When a physical port of a Host Ethernet Adapter (HEA) is partitioned, a Logical HEA is created for the partition. One or a plurality of Logical Ports (LPorts) is created in the Logical HEA. Each LPort is mapped to a corresponding physical port. During LPAR configuration, a minimum guaranteed speed is specified forthe LPort together with the corresponding physical port for the LPort and an optional maximum speed. The specified configuration for the LPort is verified, and the configuration values are stored inthe HEA and the HEA dispatches data packets based upon the stored configuration values for the LPort.

Description

technical field [0001] The present invention relates generally to the field of data processing and, in particular, to methods, apparatus and computer program products for enforcing bandwidth capping at the logical port level for shared Ethernet ports. Background technique [0002] A single Ethernet port with a capacity of eg 1Gbps or 10Gbps can be partitioned across multiple systems. For example, a single RJ-45 port can support up to 16 partitions. [0003] Known network virtualization arrangements typically use a shared Ethernet adapter that is managed by the host operating system (OS) and uses virtual network bridging. [0004] A disadvantage of traditional Ethernet adapter sharing arrangements is the provision of a data packet path through the hypervisor. In addition, packet forwarding also relies on input / output (I / O) host partitioning. [0005] An efficient mechanism is needed to enforce bandwidth capping on shared Ethernet ports. Such mechanisms need to be provided...
