Cold Data Storage

Cold data storage refers to the storage of inactive data that is rarely used or accessed. Typically, cold data must be retained for business or compliance purposes on a long-term basis, if not indefinitely. Cold data storage is generally much more economical than high performance primary storage used to support more active data.

Who uses cold data storage, and why

With the rapid growth of unstructured data, organizations across a wide range of industries are realizing the advantages of cold data storage:

    • Prevent primary storage from becoming overloaded with inactive data

    • Utilize more economical storage resources for inactive data

    • Reduce overall storage costs

    • Simplify storage and data management

    • Meet compliance and governance requirements efficiently

How cold storage works

New or frequently accessed data is typically supported on primary storage resources due to performance requirements. As this data ages and is accessed less frequently, it can generally be moved to cold data storage. A policy-based, tiering approach allows organizations to optimize storage resources and reduce costs by moving inactive data to more economical cold data storage.

Benefits of cold data storage

Cold data storage allows organizations to:

• Optimize storage resources

• Prevent primary storage from becoming overloaded with inactive data

• Utilize more economical storage resources for inactive data

• Reduce overall storage costs

• Simplify storage and data management

• Meet compliance and governance requirements efficiently
