yIBM’s Host Ethernet Adapter (HEA) integrated 2-Port 10/100/1000 Based-TX PCI-E IOA supports checksum offloading, 9000-byte jumbo frames (1 Gigabit only) and LSO - Large Send Offload (IPv4 only). These adapters do not require an IOP to be installed in conjunction with the IOA. Additionally, each physical port has 16 logical ports that may be assigned to other partitions and allows each partition to utilize the same physical port simultaneously with the following limitation: one logical port, per physical port, per partition.

Communications Performance Highlights for IBM i Operation System 6.1:

yAdditional enhancement in Internet Protocol version 6 (IPv6) in the following areas:

1.Advanced Sockets APIs

2.Path MTU Discovery

3.Correspondent Node Mobility Support

4.Support of Privacy extensions to stateless address auto-configuration

5.Virtual IP address,

6.Multicast Listener Discovery v2 support

7.Router preferences and more specific route advertisement support

8.Router load sharing.

yAdditional enhancement in Internet Protocol version 4 (IPv4) in the following areas:

1.Remote access proxy fault tolerance

2.IGMP v3 support for IPv4 multicast.

yLarge Send Offload support was implemented for Host Ethernet Adapter ports on Internet Protocol version 4 (IPv4).

5.1 System i Ethernet Solutions

The need for communication between computer systems has grown over the last decades, and TCP/IP over Ethernet has grown with it. We currently have arrived where different factors influence the capabilities of the Ethernet. Some of these influences can come from the cabling and adapter type chosen. Limiting factors can be the capabilities of the hub or switch used, the frame size you are able to transmit and receive, and the type of connection used. The System i server is capable of transmitting and receiving data at speeds of 10 megabits per second (10 Mbps) to 10 gigabits per second (10 Gbps or 10 000 Mbps) using an Ethernet IOA. Functions such as full duplex also enhance the communication speeds and the overall performance of Ethernet.

Table 5.1 contains a list of Ethernet input/output adapters that are used to create the results in this chapter.
