Information Lifecycle Management

In information technology, ILM is the movement of information of various kinds and values ​ ​ in a storage system (DSS) based on the modifying business requirements for the criteria for the security and availability of information, taking into account its value, relevance and optimization of storage costs.

The concept of ILM is based on the fact that information has a certain period of life. First, information is created that is in use by the client for a certain period of time and, as a result, it is destroyed. Throughout its life cycle, the value of information to the business is not stable and the ILM process is to determine the information resource's service level according to changes in the value of the information. In other words, protection and access to the most important data should be significantly more reliable and faster than protection and access to data of less importance. During the life cycle, the value of each information for business processes may vary over time, so the service level of a given information resource must change accordingly.

ILM Project Objectives and Areas

EMC ILM Framework

ILM's primary goal is to ensure that data is up-to-date and available by storing information at different levels of DSS, and to minimize storage costs by optimizing data placement in the DSS. The main areas of ILM include e-mail archiving, file and relational database management, storage and records management, and tiered hardware.

• By reducing the number of duplicate files and identifying and managing used and unused files, data growth is better managed.
• Simple movement - starting with the existing infrastructure, it can be increased by introducing ITIL Information Technology Infrastructure Library-compatible methods of using open systems.
• Absolute cost control - Associated with more efficient storage utilization, as well as similarities between the level of service for stored data and the time-changing value of the data.
• Dramatically improve data utilization by meeting requirements for preparation, performance, data loss risk management, and long-term storage requirements.

ILM solutions

The ILM solution is a set of template-based, business-specific management practices that enable you to modify many aspects of infrastructure implementation and administration. data storage Enterprises can begin the process of reforming their storage infrastructure to manage their information lifecycle from multiple starting points.

The Information Lifecycle Management solution enables you to introduce processes, policies, methodologies, and tools to cost-effectively position data in your storage environment according to its business value-from the time the data originates to the time it is destroyed.

Typically, companies are primarily looking to meet the needs for long-term e-mail storage, management of email attachments, and mailbox size. In this case, you can start with ERP applications, since they collect large amounts of data over time. You can use archiving tools to increase performance and reduce storage utilization in your applications. In order to reduce costs, organizations often begin with the introduction of a tiered storage infrastructure. For even greater cost savings, organizations can continue to introduce methods to manage the distribution of data across storage tiers and different appliances and their movement between storage tiers at different levels of the lifecycle.

In general, ILM is based on a baseline assessment of available storage and data. It is typically implemented in conjunction with the introduction of new disaster recovery capabilities, new data distributions from a security perspective, or the implementation of new data archiving regulations for long-term retention.

Scope

There is currently no absolute implementation of information lifecycle management. However, certain technologies are already in use today. These technologies will provide tangible advantages and make it easier to implement the transition to ILM strategy in the future. Step-by-step storage infrastructure is the main detail of the first stage of the ILM strategy implementation. Such a system establishes a sequence of storage systems based on quality of service requirements, such as business consistency, performance, data protection, security of stored information, compliance with regulations.

In fact, the infrastructure is the consolidation of a number of storage systems into a network. These systems differ in the cost and service level they provide. For any type of information and the application related to it, the most suitable storage is selected. Because absolute implementation of ILM in a heterogeneous application environment is virtually impossible, major storage vendors provide storage management tools for structured and unstructured information. New specialized solutions have been prepared for reference information management. Structured information management methods are software products that migrate data to the storage infrastructure according to established policies. The server file system or database tables may be represented as structured information.

In one case, part of the file system will move to the currently suitable storage systems in a step-by-step mode. In another case, data will be transferred from tables to an archive or to another DBMS. Unstructured information management tools are used to migrate data that does not have a pronounced structure and also require application-level integration. There are already software products on the market for managing mail archives (for example, EMC EmailXtender).

Reference information is managed through software or hardware - Content Addressed Storage (CAS). A distinctive feature of these systems is that they make it possible to find documents by content, indexing them at the time they are placed in storage. First of all, they are used in unstructured information archives. Implementing the concept of information lifecycle management in the data center infrastructure is  a long and difficult process, but you can start it and achieve a positive result now.
