ExaGrid Sytem Earns High Marks from ESG Lab Report
(Wireless News Via Thomson Dialog NewsEdge)
ExaGrid Systems, a provider of scalable disk-based backup solutions
with byte-level data de-duplication, announced the results of a lab
review by Enterprise Strategy Group (ESG), an analyst firm specializing
in the testing and analysis of specific storage-related products.
According to the company, the lab review confirmed that the ExaGrid
Disk-based Backup System provides high backup and restore rates, linear
performance and scalability with large and growing data amounts, and
substantial cost savings due to data de-duplication.
The recently published report details the results of ESG Lab's
comprehensive testing of the ExaGrid Disk-based Backup System and
validates ExaGrid's product claims in all aspects of data backup and
recovery, including high-speed backup and restore rates, data
de-duplication ratios, linear scalability, remote replication and
general ease of installation and management.
The following excerpts from the ESG Lab report discuss ExaGrid's
performance in several key areas that organizations should consider as
they evaluate a disk-based backup system with data de-duplication.
Backup and Restore Performance:
- "ESG Research indicates that performance is the top priority for data
center managers considering a disk-based backup solution. ExaGrid uses
a scalable post-process de-duplication approach for optimal backup and
recovery performance. As an organization's data grows, the ExaGrid
approach maintains day-one backup and restore performance. Using
real-world data and a real-world backup application, ESG Lab has
confirmed that ExaGrid can backup data at a rate of 4 TB/hr for a fully
configured grid. Based on ESG Lab's experience testing a number of
disk-based backup systems in recent years, this is a superb level of
performance."
Real-world Data De-duplication Ratios:
- "Data de-duplication changes the economics of backup to disk by
reducing the cost of data retained on disk. ESG Lab testing and
feedback from ExaGrid customers indicates that de-duplication can be
used to reduce disk capacity by a factor of twenty to one or more
depending on the type of data being backed up, the backup policies in
use and the number of backups retained on disk."
Linear Scalability:
- "ExaGrid scales to meet a wide variety of performance and capacity
requirements. ESG Lab found that adding a new server to an existing
grid is straightforward. Automatic spillover and migration provides the
flexibility needed to grow, maintain and tune a growing pool of
virtualized capacity. Taken together with the space savings provided by
de-duplication, the scalability of a singly-managed ExaGrid system
reduces the cost and complexity of managing growing disk-based backup
requirements."
WAN-Efficient Remote Replication:
- "ESG Lab has verified that ExaGrid's data de-duplication
significantly reduces the amount of data that needs to be transferred
over the WAN, enabling what may have otherwise been impossible or
prohibitively costly. ESG Lab has also confirmed that ExaGrid remote
replication has no impact on backup performance. It's a cost-effective
alternative to tape for offsite archival."
Ease of Setup and Management:
- "Initial configuration of an ExaGrid system is simple and intuitive.
Integration with existing backup application polices was
straightforward. The first backup job was running sixteen minutes after
beginning a configuration from scratch on a pre-wired system."
"It's easy for vendors to make big claims about their products; it's
another thing entirely to go into the lab with an outside party like
ESG and have your claims tested and fully validated," said Marc Crespi,
vice president of product management for ExaGrid Systems. "We are proud
that ESG witnessed first-hand the leading backup and restore
performance, linear scalability, effective data de-duplication and
tremendous ease of use that our customers have long enjoyed with the
ExaGrid Disk-based backup System."
"ESG Lab believes that organizations struggling with the cost,
complexity and risk associated with tape backups would be wise to
consider the bottom line savings that can be achieved with ExaGrid:
faster backups, quicker and more reliable restores, lower risk, lower
expenses (capital and operational) and last, but not least, a greener
solution with optimized power and cooling," said Claude Bouffard, ESG
Lab engineer.
