HP ProLiant Essentials Intelligent Networking Pack Introduction

The HP ProLiant Essentials Intelligent Networking Pack-Windows Edition is part of the ProLiant Essentials software family and is integrated with HP Systems Insight Manager (SIM), SmartStart, and HP Management agents.

The Intelligent Networking Pack (INP) provides advanced capabilities that allow servers to proactively adapt to networking infrastructure problems thus improving server availability and network performance. The Intelligent Networking Pack Windows Edition includes:

• Virus Throttle—a network packet-filtering feature that 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 ("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 redundancy and teaming capabilities, including:

o Active Path Failover—an advanced redundancy feature that allows a ProLiant server to detect

blocked paths and to redirect data along an unblocked path to the core network.

o Fast Path Failover—an advanced redundancy feature that allows a ProLiant server to use the

quickest path to the core network (or the root bridge).

o Router Path Failover—an advanced redundancy feature that allows a ProLiant server to detect a

blocked path to a router and to redirect packets along an unblocked path to a router.

o Dual Channel Load Balancing—a special type of teaming that 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.

o Dual Channel Network Fault Tolerance—a special type of teaming that 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,

Overview 4

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.

NOTE: Dual Channel Network Fault Tolerance teaming capabilities are not supported on

systems running Windows® 2000.

• Cisco Discovery Protocol (CDP) support—a media- and protocol-independent network protocol that is

used to obtain protocol addresses of neighboring devices and discover the platform and other information of those devices.

• Link Layer Discovery Protocol (LLDP) support—a media- and protocol-independent network protocol

that is used to obtain protocol addresses of neighboring devices and discover the platform and other information of those devices.

• Internet Group Management Protocol (IGMP) support—IGMP is a session-layer (Layer-3) protocol

used to establish membership in a Multicast group. It can register a router to receive specific multicast traffic.

The INP features are included with the networking software (release 7.71 and higher). To enable the INP features, an INP license must be installed on the system. This user guide describes how to install these licenses on your system and how to configure the features.

For the latest driver, firmware, and documentation updates, go to HP Networking website (http://h18004.www1.hp.com/products/servers/networking/index.html

Intelligent Networking Pack licenses

Each server requires a separate INP license. When installed on the system, the license is "attached" to the server and cannot be revoked. The license will stay with that server for the life of the server. The license is associated with the server's serial number, so a change in the server's name or IP address will not invalidate the license. One INP license enables all INP features on the server.

Four categories of INP licenses are available. Each license offers full, unlimited functionality.

• Single license pack—Authorizes one licensed seat.

• Flexible Quantity license pack—Authorizes the set number of licensed seats ordered.

• Activation Key Agreement license pack—Allows you to authorize additional licensed seats under the

terms of a signed and implemented Activation Key Agreement (AKA) only.

Installing an Intelligent Networking Pack license

• Demo—Allows you to evaluate the features for a set number of seats and a set number of days

INP-Windows Edition licenses can be installed through the following:

How Virus Throttle works

Viruses typically spread by connecting to as many different machines as possible. Virus Throttle is a network packet-filtering feature that monitors all outbound connection requests. Virus Throttle helps to stop the spread of viruses on your system by detecting abnormal "virus like" behavior in the requests. It slows down excessive connection requests to new hosts until you can determine if they are viral in nature and take action.

Virus Throttle allows the network infrastructure to stay up and running by slowing traffic on systems that exhibit high connection rates and frequent connections to new hosts.

When you install Virus Throttle on your system, the Virus Throttle network NDIS filter driver is inserted into all existing protocol-to-miniport bindings and all network traffic passes through it. Virus Throttle provides TCP and UDP support. The driver maintains a delay queue of connection requests for each instance of the network protocol stack and a list of known hosts that have established connections.

The driver examines all outbound connection requests and determines if the request is for a known host. If known, the request is passed down the protocol stack as a normal request. If unknown, the request is added to the delay queue. Periodically, the delay queue is examined and the oldest request is removed and passed down the protocol stack.

High and low water marks or pre-set thresholds are maintained for the delay queue and are used to determine when "virus-like" behavior is occurring or has stopped.

• High water mark—When the rate of connection requests exceeds the rate of the driver removing

them from the delay queue, a high water mark in the queue is exceeded and the driver indicates "virus-like" activity.

• Low water mark—When the rate of connection requests drops so that the number of queue entries

fall below a low water mark, the driver indicates that the "virus-like" activity has stopped.

When "virus-like" activity is detected or has stopped, Virus Throttle sends a Windows Management Instrumentation (WMI) event notification to the administrator. If HP Management agents are installed and configured correctly, a Simple Network Management Protocol (SNMP) trap warning is also sent to the administrator.
