There are six 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 six configurations can be mixed and matched into a single GRID system, with full backup capacities up to 100TB, in granular 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.
ExaGrid's unique approach to scalability provides the following benefits:
• Performance is maintained as your data grows - each additional ExaGrid server added to a system provides disk, processor, memory and GigE
• Capacity utilization is load-balanced across servers - as a single server reaches full utilization, it can leverage space available on other servers in the GRID
• Plug and play expansion - adding an additional ExaGrid server is as simple as plugging it in and letting ExaGrid's automatic virtualized GRID software do the rest
• Cost-Effective and Flexible Solution with No "Forklift" Upgrades - no need to over-buy storage capacity up front – modular systems are easily combined in a virtualized GRID to smoothly scale up for larger capacities as needed with no painful “forklift” upgrades.
Six 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 100TB system is required, then ten EX10000Es are plugged into the switch and virtualize into a single system
