Introduction to PowerHA
Introduction to PowerHA
PowerHA for AIX is the new name for HACMP (High Availability Cluster Multiprocessing). HACMP is an application that makes system fault resilient and reduces downtime of applications. This article introduces PowerHA and provides a detailed explanation of how to configure a two node cluster. This document is very useful for understanding PowerHA and setting up a two node cluster.

High availability with the Linux Distributed Replicated Block Device
High availability with the Linux Distributed Replicated Block Device
The 2.6.33 Linux kernel has introduced a useful new service called the Distributed Replicated Block Device (DRBD). This service mirrors an entire block device to another networked host during run time, permitting the development of high-availability clusters for block data. Explore the ideas behind the DRBD and its implementation in the Linux kernel.

Distributed data processing with Hadoop, Part 2: Going further
Distributed data processing with Hadoop, Part 2: Going further
Learn advanced setup that uses multiple nodes for parallel processing. It demonstrates the various node types required for multinode clusters and explores MapReduce functionality in a parallel environment. This article also digs into the management aspects of Hadoopóboth command line and Web based.
Difficulty:
Distributed data processing with Hadoop
Distributed data processing with Hadoop
This article explores the Hadoop framework, including its fundamental elements, such as the Hadoop file system (HDFS), and node types that are commonly used. Learn how to install and configure a single-node Hadoop cluster, and delve into the MapReduce application. Finally, discover ways to monitor and manage Hadoop using its core Web interfaces.

Ganglia and Nagios Cluster monitoring Part 2
Ganglia and Nagios Cluster monitoring Part 2
The scope of Ganglia and Nagios is enormous. What we have touched on here though is relevant to a cluster, grid, or cloud infrastructure. In Part 2, learn how to install and configure Nagios to watch hosts and services, alerting users when things go wrong. The article also shows you how to unite Nagios with Ganglia (from Part 1) and add two other features to Nagios for standard clusters, grids, and clouds to help with monitoring network switches and the resource manager.
Difficulty:
Linux high-performance cluster monitoring with Ganglia
Linux high-performance cluster monitoring with Ganglia
This article will walk you through Installing and configuring the basic Ganglia (a scalable, distributed monitoring system for high-performance clusters) setup. it will also show you how to use the Python modules to extend functionality with IPMI, and how to use Ganglia host spoofing to monitor IPMI. The goal is not only to set up a Ganglia high-performance Linux cluster monitoring system, but also to add more monitoring capability by writing simple Ganglia plug-ins.

Parallel Machine Learning Toolbox for Linux
Parallel Machine Learning Toolbox for Linux
Many sophisticated machine learning algorithms cannot process large amounts of data on a single node, but Parallel Machine Learning Toolbox (PML) can do so by distributing the computations. This distribution speeds up computations and expedites training by weeks, days, or even hours in an easy, reliable way. PML can run on a wide array of architectures including single-node, small clusters, grids, and BlueGene.

11 secrets for lazy Linux cluster admins
11 secrets for lazy Linux cluster admins
Managing Linux clusters requires a unique set of skills that are not usually found among the single-system or small-networked-systems IT administrators. In this article, the authors peer into the minds of the laziest Linux admins on Earth and divulge their secrets for mastering the techniques of scale-out management.

Make an Adminís job easier with HACMP/XD-PPRC
Make an Adminís job easier with HACMP/XD-PPRC
HACMP/XD uses PPRC mirroring technology to provide disaster recovery for critical applications' data. This involves collecting configuration data from the storage as well as from the cluster nodes; at times this can be tedious. This article shows you how, using pprc4hacmp, configuration data is generated automatically for HACMP/XD-PPRC.
