HP Integrity rx4640 Server - Manual (Page 9)

1 Introduction
This document provides information about installing HP Integrity Essentials Intelligent
Networking Pack licenses and configuring Intelligent Networking Pack features.
Overview
The HP Integrity Essentials Intelligent Networking Pack (INP) enables your servers to actively
adapt to networking infrastructure problems, thereby improving server availability and network
performance. INP is part of the Integrity Essentials software family and is integrated with HP
Systems Insight Manager and HP Management agents.
The Intelligent Networking Pack includes all of the following features:
•
Virus Throttle: this network packet-filtering tool helps slow down the spread of viruses on
your system. Virus Throttle monitors all outbound connection requests and counts the
number of unique connections. It detects abnormal or “virus-like” behavior in the requests,
and slows down excessive connection requests to new hosts until you can determine if they
are viral in nature and take action.
• Advanced networking capabilities: these redundancy features let HP Integrity servers
adapt and change network paths to achieve maximum reliability and performance. They
can detect and analyze network bottlenecks or broken network linkages, and then redirect
traffic to the optimum route based on current conditions.
Advanced networking features include:
— Active Path Failover: allows an Integrity server to detect and bypass failed network
paths
— Fast Path Failover: allows an Integrity server to determine the fastest path to the core
network (or the root bridge)
— Router Path Failover: allows you to assign multiple routers to a single router group,
with one of them functioning as the “active” router that forwards packets. If that router
fails, a second one takes over.
— Dual Channel Load Balancing: allows the creation of two teams, called groups, inside
of a single team. Each group is assigned one or more teamed ports and can be connected
to a different switch to provide switch fault tolerance. Full inbound and outbound load
balancing is provided across both groups. Should any group completely fail, caused by
a failure of all teamed ports in the group or by a failure of the group's switch, the team
remains available through the other group. Two types of Dual Channel Load Balancing
teams can be configured: Switch-assisted Dual Channel Load Balancing teams and
802.3ad Dynamic Dual Channel Load Balancing teams.
— Dual Channel Network Fault Tolerance: allows the creation of two teams, called groups,
inside of a single team. All team members within each group are dynamically placed
into a port-trunk/channel by dynamic Link Aggregation Control Protocol (LACP)
agreement with the switch. A failure of a team member to synchronize joining a
port-trunk or channel with the switch is treated as an error and that team member is
considered failed. Dynamic Dual Channel Network Fault Tolerance (NFT) provides the
safety of additional backup links between the server and hub/switch. Dynamic Dual
Channel NFT is implemented with one channel team providing a primary adapter and
another channel team providing a secondary, backup adapter. During normal operations,
if the adapters in the primary team fail, a link to one of the adapters in the secondary,
backup team automatically takes over. Four types of Dual Channel NFT teams can be
configured: Switch-assisted Dual Channel NFT teams, Switch-assisted Dual Channel
NFT and Preference Order teams, 802.3ad Dynamic Dual Channel NFT teams, and
802.3ad Dynamic Dual Channel NFT and Preference Order teams.
