  • Etherchannel & Highly Available Cluster Multiprocessing (HACMP) in AIX V5.2
    EtherChannel & Highly Available Cluster Multiprocessing (HACMP) in AIX V5.2 How-to and Test Experiences Abstract: This document gives tips and a working example of how to a Highly Available Cluster Multiprocessing (HACMP) user could implement EtherChannel with HACMP. Support for this combination was announced in May, 2004. Authors: Shawn Bodily (HACMP) and Cindy Young (EtherChannel) of IBM pSeries Advanced Technical Support and Michael Herrera (HACMP) of IBM pSeries AIX Support Introduction IBM AIX pSeries administrators have expressed interest in combining these components for several reasons. Those accustomed to other software availability solutions object to HACMP’s additional “standby” adapter. With EtherChannel, HACMP setups could mask the standby adapter giving an outward appearance familiar to these users. Other users like the aggregated bandwidth, load balancing, or high availability benefits of EtherChannel. The result is a lower cost, high performance network that is also popular as a high speed private (non-switch) interconnect between machines. In this test, we successfully implemented a “single adapter network” HACMP IP Address Takeover (IPAT) with the EtherChannel function included in AIX V 5.2. The EtherChannel was responsible for providing local adapter swapping – outside of HACMP. HACMP has no knowledge of EtherChannel and is completely independent. While a single adapter network is normally not ideal, EtherChannel makes this okay because there are multiple physical adapters within the single EtherChannel pseudo device. Thus, we could safely ignore the insufficient adapter warning messages posted during cluster synchronization. Our configuration consisted of a rotating resource group with a single adapter network using IP aliasing. Our testing proved to be beneficial in simplifying the HACMP setup.

  • Application Notes
    A Sample Configuration with Design Guidelines for Link Aggregation Between Avaya™ P580/P882 Gigabit Ethernet Switch Hunt Groups and Cisco EtherChannel - Issue 1.0 Abstract These Application Notes describe a sample Hunt Group/EtherChannel Link Aggregation Group (LAG) configuration between an Avaya™ P882 Gigabit Ethernet switch and a Cisco Catalyst 6509 switch. Design guidelines for deploying LAG in a mixed Avaya/Cisco infrastructure are included as an aid for network designers. A sample configuration diagram has been included along with provisioning notes. These Application Notes were created as a result of field requests for information on interoperability between Avaya P580/P882 Hunt group trunks and Cisco EtherChannel. GAK; Reviewed: Solution & Interoperability Test Lab Application Notes 1 of 15 WCH 7/18/2003 ©2003 Avaya Inc. All Rights Reserved. cislaginterop.doc 1. Introduction The Avaya™ P580/P882 Gigabit Ethernet Switch Hunt Group feature aggregates multiple switch ports together, combining the bandwidth into a single connection. This feature is normally deployed between switches to provide added bandwidth and fault tolerance. If one segment in a hunt group fails, the remaining active members will service the traffic for that segment. The Hunt Group Load-Sharing feature (enabled by default) distributes traffic load among the hunt group members for improved throughput performance. Hunt group member ports can be configured using various trunk modes including IEEE 802.1Q, Multi-layer, 3Com and Clear. Hunt group ports may also be assigned a router IP interface for layer 3 forwarding. The Avaya™ Hunt Group feature is a manual (or static) implementation of link aggregation. This means the feature does not support dynamic LAG configuration or binding via some standard or proprietary protocol.

  • Chapter 2 Lab 2-2, Configuring Etherchannel
    CCNPv6 SWITCH Chapter 2 Lab 2-2, Configuring EtherChannel Topology Objective • Configure EtherChannel. Background Four switches have just been installed. The distribution layer switches are Catalyst 3560 switches, and the access layer switches are Catalyst 2960 switches. There are redundant uplinks between the access layer and distribution layer. Usually, only one of these links could be used; otherwise, a bridging loop might occur. However, using only one link utilizes only half of the available bandwidth. EtherChannel allows up to eight redundant links to be bundled together into one logical link. In this lab, you configure Port Aggregation Protocol (PAgP), a Cisco EtherChannel protocol, and Link Aggregation Control Protocol (LACP), an IEEE 802.3ad open standard version of EtherChannel. Note: This lab uses Cisco WS-C2960-24TT-L switches with the Cisco IOS image c2960-lanbasek9-mz.122- 46.SE.bin, and Catalyst 3560-24PS with the Cisco IOS image c3560-advipservicesk9-mz.122-46.SE.bin. You can use other switches (such as a 2950 or 3550) and Cisco IOS Software versions if they have comparable capabilities and features. Depending on the switch model and Cisco IOS Software version, the commands available and output produced might vary from what is shown in this lab. Required Resources • 2 switches (Cisco 2960 with the Cisco IOS Release 12.2(46)SE C2960-LANBASEK9-M image or comparable) • 2 switches (Cisco 3560 with the Cisco IOS Release 12.2(46)SE C3560- ADVIPSERVICESK9-M image or comparable) All contents are Copyright © 1992–2010 Cisco Systems, Inc.

    Front cover IBM PureData System for Analytics Architecture A Platform for High Performance Data Warehousing and Analytics Redguides for Business Leaders Phil Francisco Take advantage of the power and simplicity of a purpose-built appliance for high speed metrics Improve the quality and timeliness of business intelligence Query data quickly, efficiently, and economically Executive overview Success in any enterprise depends on having the best available information in time to make sound decisions. Anything less can waste opportunities, cost time and resources, and even put the organization at risk. But finding crucial information to guide the best possible actions can mean analyzing billions of data points and petabytes of data, whether to predict an outcome, identify a trend, or chart the best course through a sea of ambiguity. Companies with this type of intelligence on demand can react faster and make better decisions than their competitors. Continuing innovations in analytics provide companies with an intelligence windfall that benefits all areas of the business. When you need critical information urgently, the platform that delivers this information should be the last thing on your mind. The platform needs to be as simple, reliable, and immediate as a light switch, able to handle almost incomprehensible workloads without complexity getting in the way. It must be built for longevity, with a technology foundation that can sustain performance as more users run increasingly complex workloads and as data volumes continue to grow. Furthermore, to maximize returns to the business, it needs the lowest total cost of ownership. The IBM® PureData® System for Analytics, powered by Netezza® technology, transforms the data warehouse and analytics landscape with a platform that is built to deliver price-performance with appliance simplicity.
