Scalability Provides for a Staged Rollout
Besides ExaGrid’s interoperability with Veeam, a big factor in Dycom’s selection of ExaGrid was how easy it is to expand.
The ExaGrid system can easily scale to accommodate data growth. ExaGrid’s software makes the system highly scalable – appliances of any size or age can be mixed and matched in a single system. A single scale-out system can take in up to a 2.7PB full backup plus retention at an ingest rate of up to 488TB per hour.
ExaGrid appliances contain not just disk but also processing power, memory, and bandwidth. When the system needs to expand, additional appliances are simply added to the existing system. The system scales linearly, maintaining a fixed-length backup window as data grows so customers only pay for what they need, when they need it.
Data is deduplicated into a non-network-facing repository tier with automatic load balancing and global deduplication across all repositories. “It’s simply a matter of getting a new appliance, adding it to the system, and it all ties together. Actually, we moved one of our locations, and it was really straightforward. We bought an extra ExaGrid and we moved a whole site through it. We installed V Center, migrated everything to the ExaGrid, and then shipped the system to the new location. When the ExaGrid was delivered, it came right on, and we migrated everything to the new location – it was all really pretty simple,” Santana said.
Dycom’s ultimate goal is to have ExaGrid appliances in each of its 700 locations. According to Santana, for the locations that have good Internet access, Dycom is backing up to its Atlanta the ExaGrid. For the remaining locations, they’ll continue to use local storage for now and send everything to Amazon Web Services (AWS) for long-term archival. Dycom is required to keep archived data for seven years.
Once Dycom has ExaGrid appliances in place in its various locations, Santana hopes to cross-replicate for disaster recovery protection. Currently, Dycom is storing 400TB on its existing ExaGrid systems.
