EXPERIMENT NO: 1
AIM: To study Information Life Cycle Management.

THEORY:

INFORMATION LIFECYCLE:
The information lifecycle is the “change in the value of information” over time.
When data is first created, it often has the highest value and is used frequently.
As data ages, it is accessed less frequently and is of less value to the organization.
Understanding the information lifecycle helps to deploy appropriate storage infrastructure, according to the changing value of information.

For example, in a sales order application, the value of the information changes from the time the order is placed until the time that the warranty becomes void (see Figure 1-7). The value of the information is highest when a company receives a new sales order and processes it to deliver the product.
After order fulfillment, the customer or order data need not be available for real-time access. The company can transfer this data to less expensive secondary storage with lower accessibility and availability requirements unless or until a warranty claim or another event triggers its need. After the warranty becomes void, the company can archive or dispose of data to create space for other high-value information.

Information Lifecycle Management
Today’s business requires data to be protected and available 24 × 7. Data centers can accomplish this with the optimal and appropriate use of storage infrastructure.
An effective information management policy is required to support this infrastructure and leverage its benefits.
Information lifecycle management (ILM) is a proactive strategy that enables an
IT organization to effectively manage the data throughout its lifecycle, based on predefined business policies. This allows an IT organization to optimize the storage infrastructure for maximum return on investment. An ILM strategy should include the following
