Scale-Out Architecture Keeps Pace with Data Growth
Paul has been impressed by the amount of data that can be stored thanks to ExaGrid’s deduplication, but when data growth caused space to become a bit limited, he decided to scale out the system by adding another appliance. “ExaGrid’s deduplication and compression are better than our prior system, so we’re able to store much more data. We added an appliance, and that was quite easy to do. We installed it, and our support engineer held a Webex session with us to configure the system. Scalability is one of ExaGrid’s best features.”
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.
