Abstract
The presentation describes the components and implementation of a highly available NAS gateway built from open source software. Using industry standard hardware and open source OS and HA clustering tools AOL has built a replacement for high cost commercial NAS systems. The performance and availability characteristics approach the capabilities of high cost commercial systems for a fraction of the cost.
Learning Objectives
