For many organizations, the process of designing and deploying an effective tiered storage system can

be accelerated and simplied by working with vendors who can provide a complete portfolio of storage

devices, media, management software, and services as well as optimize the organization’s existing

technology investments. The right vendor can help an organization understand how data aligns with

changing business requirements, translate them into multiple tiers of storage with varying cost and

performance proles, and simplify the process of implementation.

The result will be a tiered data environment where storage administrators can:

• View and search through structured and unstructured data types residing on any storage tier

• Provision tiered storage resources dynamically and non-disruptively

• Migrate data (data mobility) among tiers non-disruptively

All of the above functions should be manageable from a central point of control.

Data Movement, Software, and Tiered Storage

Tiered storage has begun to deliver more strategic business benets through the use of software.

Organizations are subdividing enterprise storage into tiers on the basis of performance, availability and other

factors and using data movement software to automatically redistribute the data across tiers in accordance

with business policies. Backup software is also used – working throughout the storage environment to meet

business continuity and disaster recovery requirements. And to ensure that the administration of the tiered

system doesn’t increase in complexity, thus offsetting its benets, heterogeneous storage management

software, as discussed above, is helping keep overall TCO under control.

Data movement technologies, and especially database pruning/tuning applications, have developed

into important tools in the design and implementation of a tiered storage environment. Data

movement software allows IT administrators to allocate les to different tiers based on business

policies dened by metadata. Data is then automatically promoted or relegated to storage tiers based

upon application and user needs.
