Taneja Group Recognizes ExaGrid as the Model for Disk-Based Data Protection; Report Highlights ExaGrid's Strength in Capacity Optimization, Scalability, Reliability and Ease of Deployment

Business Wire, July 24, 2006

WESTBOROUGH, Mass. -- Taneja Group analysts recognized ExaGrid Systems as a leader in advanced disk-based data protection in a June 2006 report titled, "ExaGrid: An Intelligent Approach to Data Protection." The research indicates ExaGrid is a leading solution for organizations seeking a simple, scalable, reliable solution that easily integrates with existing backup applications.

"Organizations are demanding cost-efficiency, ease of use, scalability, and ease of integration with their pre-existing environments," said Brad O'Neill, senior analyst of Taneja Group. "We view ExaGrid as a forward-looking, cost-effective disk-based architecture that encapsulates where the next generation data protection is heading."

Taneja Group found that ExaGrid leverages the economic benefits of industry-standard hardware on a "scale-out" grid platform, while incorporating a range of advanced software functionality to optimize capacities across geographies. According to Taneja Group, ExaGrid represents where the entire industry must follow: easily deployed, self-contained disk-based data protection "clusters" designed to fit into any existing enterprise data center and delivering results out-of-the-box.

The Taneja Group found a number of key differentiators in ExaGrid including:

--Capacity Optimization - ExaGrid's byte-level delta data reduction stores only the changes from backup to backup instead of storing full file copies, reducing the amount of disk space needed to at least 20 to 1, resulting in tremendous cost savings.

--Modular Architecture - ExaGrid's architecture can be scaled "on the fly," as opposed to traditional modular or monolithic storage solutions.

--Non-Disruptive Scaling - ExaGrid scales without disrupting IT operations to add linear performance, throughput and overall capacity and enables users to mix CPU speeds and disk capacities in the same deployment.

--Second Site Flexibility - Organizations can choose to deploy an additional ExaGrid system at a second site to replicate data stores for offsite protection and disaster recovery.

--Open, Total Protection - ExaGrid's architecture can serve as a backup target for any host-based application. Currently supported backup applications include ARCServe, Symantec BackupExec, Symantec NetBackup, Commvault Galaxy, IBM TSM and Microsoft SQL Dump.

--Verified Integrity - ExaGrid automatically performs integrity verification on every file written into the repository, ensuring verified recoverability of any data element in the ExaGrid system.

"Taneja Group's research offers pragmatic and forward-thinking advice about storage and backup technology to companies looking for the best solutions for their needs," said Bill Andrews, president and CEO of ExaGrid. "This report articulates what our customers already know--ExaGrid provides the best ease of integration, smooth scaling, and capacity optimization, which results in significant ROI."
