POWER6 Champions Class - May 2007IBM Virtual I/O Server (VIOS)Host Ethernet Adapter(HEA) Virtual I/O Server Virtual I/O Server Virtual Networking Virtual Ethernet Adapter allows logical partitions to send and receive network traffic without a physical Ethernet adapter created in LPARs using HMC or IVM HMC/IVM generates MAC address Local bit to prevent conflict with physical Ethernet Based on machine serial number for uniqueness Access to 21 VLAN (VID) networks per adapter PVID + 20 Additional VID Shared Ethernet Adapter (SEA) A Shared Ethernet Adapter is a Virtual I/O Server component that bridges a physical Ethernet adapter and one or more virtual Ethernet adapters Bridges virtual and physical networks Physical resource can be shared by multiple networks Physical access can be a single adapter or an aggregate of adapters (EtherChannel/Link Aggregation) Shared Ethernet operates at layer 2 Virtual Ethernet MAC visible to outside systems Broadcast/Multicast support Host Ethernet Adapter (HEA) - Overview The Host Ethernet Adapter (HEA) is a shareable integrated Ethernet controller Each physical HEA controller is capable of providing up to two 10G ports or four 1G ports Up to 32 logical ports can be defined on one HEA One or more physical HEA may be present in a POWER6 System p or i series system. Provides equivalent performance as a dedicated Ethernet adapter HEA AKA IVE(Integrated Virtual Ethernet) Host Ethernet Adapter (HEA) – Overview cont’d Fair sharing of HEA Physical port bandwidth ensured by HEA hardware between LHEA Ports Isolation: Protection between partitions Value-add/offload features: Large Send, Checksum Offload, Jumbo Frames, RX interrupt coalescing, etc. Connectivity between partitions located on the same server Virtualization: HEA Logical Port Concept To a LPAR, a HEA logical port appears as a generic Ethernet interface With its own resources and MAC address Sharing bandwidth w/ other logical ports defin
