Abstract
Disaster Recovery with General Parallel File System 2.2 The ability to detect and quickly recover from a massive-scale hardware failure is of paramount importance to businesses that make use of real-time data processing systems. General Parallel File System (GPFS) provides a number of features that facilitate the implementation of highly-available GPFS environments capable of withstanding catastrophic hardware failures. By maintaining a redundant replica of the file system’s data at another (geographically separated) location, we allow the system to sustain its processing using the secondary replica of the data in the event of a total failure in the prime environment. In this paper, we present an overview of the disaster recovery features available in the 2.2 release of GPFS and provide detailed hands-on guidance on implementing the various types of disaster-tolerant configurations supported in this release. Overview and terminology Businesses that depend on real-time data processing systems are vulnerable to a profound negative impact from natural or unnatural disasters such as fires, tornadoes, earthquakes, or power failures. A catastrophe can permanently disable the customer’s data processing infrastructure and, without proper backup procedures, result in a permanent loss of businesscritical
