Scale-out Architecture Provides Required Scalability
ExaGrid’s award-winning scale-out architecture provides customers with a fixed-length backup window regardless of data growth. Its unique disk-cache Landing Zone allows for the fastest backups and retains the most recent backup in its full undeduplicated form, enabling the fastest restores.
ExaGrid’s appliance models can be mixed and matched into a single scale-out system allowing a full backup of up to 2.7PB with a combined ingest rate of 488TB/hr, in a single system. The appliances automatically join the scale-out system. Each appliance includes the appropriate amount of processor, memory, disk, and bandwidth for the data size. By adding compute with capacity, the backup window remains fixed in length as the data grows. Automatic load balancing across all repositories allows for full utilization of all appliances. Data is deduplicated into an offline repository, and additionally, data is globally deduplicated across all repositories.
This combination of capabilities in a turnkey appliance makes the ExaGrid system easy to install, manage, and scale. ExaGrid’s architecture provides lifetime value and investment protection that no other architecture can match.
CSEA originally purchased its first ExaGrid appliance approximately four years ago and has expanded the system twice since then by adding units to the scale-out system. Neal said that the organization is considering expanding the system again in the coming fiscal year to handle expected data growth. “Expanding the ExaGrid system really couldn’t be easier. After racking the system up, I call into our ExaGrid support engineer, and he guides me through the configuration steps. It takes only about an hour to add another unit to our system. It’s that simple,” she said.
