IP Multipathing (IPMP) Software
The Solaris operating environment implementation of IPMP provides the following features(Table 7-1).
Table 7-1 IPMP Features|
Feature |
Description |
|---|---|
|
Failure detection |
Ability to detect when a network adaptor has failed and automatically switches over network access to an alternate network adaptor. This assumes that you have configured an alternate network adapter. |
|
Repair detection |
Ability to detect when a network adaptor that failed previously has been repaired and automatically switches back (failback) the network access from an alternate network adaptor. This assumes that you have enabled failbacks. |
|
Outbound load spreading |
Outbound network packets are spread across multiple network adaptors without affecting the ordering of packets in order to achieve higher throughput. Load spreading occurs only when the network traffic is flowing to multiple destinations using multiple connections. |
The IP Network Multipathing (IPMP) software provides three important features:
-
If your system is configured with an alternate network adapter, then it can failover from one network path to another.
-
It can also failback to the original network adapter, after it is repaired.
-
The IP Network Multipathing software also spreads out the outbound network load between the two network adapters, to achieve higher throughput. Load spreading only occurs when the outbound network traffic is flowing to multiple destinations using multiple connections.
For more information on IP network multipathing (IPMP), refer to the IP Network Multipathing Administration Guide, which is available with your Solaris operating environment release. The IP Network Multipathing Administration Guide explains basic IPMP features and network configuration details. This book is available online with your Solaris operating environment release.
