EXAGRID Disk-based Backup with Data De-duplication
ExaGrid offers the fastest and most scalable disk-based backup system with data de-duplication at the best price in the industry.
Eliminates failed backups and restores Greatly reduces your backup window Works with your existing backup application Perfect for environments with backups of 1TB to 60TB Disk-based backup with compression/data de-duplication at the cost of tape Optional WAN-efficient offsite system for tape replacement/disaster recovery ExaGrid's byte-level data de-duplication technology stores changes from backup to backup instead of storing full file copies. This unique approach reduces the disk space required by 10 to 50:1, or more, delivering unparalleled cost savings and performance.
ExaGrid Product LineExaGrid offers a highly scalable disk-based backup system that works with your existing backup application and combines high quality SATA storage, compression and byte-level data de-duplication with a virtualized GRID architecture. This unique approach reduces the disk space required for backup by a range of 10 to 50:1, delivering unparalleled cost savings and performance at a fraction of the price of standard SATA disk storage.
Scalable GRID Architecture
There are five core ExaGrid disk-based backup servers. These servers include
GRID computing software. When plugged into a switch they virtualize into
one another. As a result, any of the five configurations can be mixed and
matched into a single GRID system, with capacities up to 60TB, in 1TB increments.
Once virtualized, they appear as a single system to the backup server. Load
balancing of all data across servers is automatic and multiple GRID systems
can be combined for additional capacity.
Five Core ExaGrid Server Configurations
For example, a 5TB ExaGrid server can store a 5TB full backup (5TB of primary data) plus up to 16 weeks of retention/history, while a 2TB server can take in a 2TB full backup (2TB of primary data) plus up to 16 weeks of retention. If a 20TB system is required, then four EX5000s are plugged into the switch and virtualize into a single system.

Scalability and Performance
A 1TB to 5TB ExaGrid server in combination with the virtualized GRID architecture
allows for the following:

Core Server Components
ExaGrid servers are comprised of the following:
Each server includes the appropriate amount of processor, memory, disk and GigE for the amount of data. As each server is plugged into the switch and virtualized into the GRID it brings not only disk capacity but also processor, memory and GigE such that performance is maintained as data is added.
Summary
ExaGrid’s unique approach to scalability provides the following benefits
Eliminate the challenges of
tape backup without changing
your backup budget.
