Scale-out storage is a type of storage architecture in which devices in connected arrays add to the storage architecture to expand disk storage space. This allows for the storage capacity to increase only as the need arises. Scale-out storage architectures adds flexibility to the overall storage environment while simultaneously lowering the initial storage set up costs.
With data growing at exponential rates, enterprises will need to purchase additional storage space to keep up. This data growth comes largely from unstructured data, like photos, videos, PowerPoints, and Excel files. Another factor adding to the expansion of data is that the rate of data deletion is slowing, resulting in longer data retention policies. For example, many organizations are now implementing “delete nothing” data policies for all kinds of data. With storage demands skyrocketing and budgets shrinking, scale-out storage can help manage these growing costs.
