Scale-Out vs. Scale-Up: Why Backup Storage Architecture Matters

Is the world of IT drowning in data? Experts estimate that organizations this year are generating more than 2.5 exabytes (2,500,000,000,000,000,000 bytes) of new data—every day.1 With various experts predicting that the compound annual growth rate of data will increase from 33% to over 60%, one thing is clear: You’re going to need more storage and soon.

The problem of backing up all that data is one of scalability. As fast as data is growing, so too is the need for backup storage that can scale and grow in capacity to meet the growth of primary storage. However, most backup storage solutions just cannot keep up with the explosive growth that many organizations are struggling with today. Just adding disk capacity without any additional computer can easily blow through backup windows and extend the time required for backups well into working hours, eventually impacting daily operations to the point that employees can’t get their jobs done during the workday.

Scalability was one of the pillars for which ExaGrid designed its backup storage solutions. ExaGrid can deliver a fixed backup window, even as the amount of data continues to grow, by enabling the addition of resources for CPU, memory, network bandwidth and disk—doubling, tripling or quadrupling the original installation as needed to keep the backup window exactly where It needs to be to get the job done on time.

This enables ExaGrid solutions to scale to a full backup of up to 2.69 petabytes—the largest capacity in the industry per system—while still maintaining an ingestion rate of 488 terabytes per hour, even with a full 2 PB-plus backup—the fastest in the industry. This is in stark contrast to other backup storage solutions where adding more disk translates to adding more time to the backup.

Some backup storage vendors’ solution to scaling out is to perform a forklift upgrade to a newer, higher capacity model—at a steep price. ExaGrid takes a much different approach. First, there is no obsolescence with ExaGrid systems. When capacity is added, new ExaGrid systems work right alongside existing systems to help ensure cost-effective scalability as data needs grow. Any age and any size appliance can be mixed and matched in a single scale-out solution. Simply add more appliances.

Finally, organizations can take advantage of ExaGrid’s price protection: five years at the same price as the original installation. ExaGrid offers the largest capacity, fastest backup and best price/performance in the market to support the unprecedented growth of data that is expected to continue long into the future.
