Definition of ILM
The policies, processes, practices, services and tools used to align the business value of information with infrastructure from the time information is created the most appropriate and cost-effective through its final disposition. Information is aligned with business requirements through management policies and service levels associated with applications, metadata and data.
ILM is a standards-based, business-driven management practice

ILM Principles
Information is data with contextInformation runs the businessInformation is your competitive advantage
The business unit understands informationAnd its value – or cost if it is missing
The infrastructure will become a utilitySo ultimately, it’s all about the data
ILM enables growth of resources & processesAutomation of processes & infrastructureBusiness driven

What is Data Classification?
Process & policies to define service requirements for dataAllows IT to create multiple service level offeringsAllows LOB to select services based on value of dataMay use software to enable some of the process
Represent corporate requirements:Security officer: Secret, confidential, proprietary, …Records Manager: retention time, …Compliance officer (HIPAA, SOX, …): authorization, retention, …
Represent LOB requirements:Application performance, availability, recoverability, …Staff response time, asset reporting, …
IT Organization needs data classification:Method to rationalize requirements into service level offerings

How is Data Classified?
Data Policies, SLOs & Data Classification are tightly coupled
Classify by applicationAll data assigned same classificationSimple; good start; a first approximationNet effect: ranking of applications to services
Classify by groups of dataProduction dataArchive dataCompliance data
Classify by metadataTime last accessed, owner, etcE.g., HSM for a file server
Classify by informationContent-driven alignment of data and SLOs

Inactive Data Consume Resources
Often 80% of all stored files have not been accessed in last 30 daysPrimary storage of inactive data is increasingly costly and inefficient

Tiers of Storage
Many ways to implement:Static
Deploy n-tiers of storage in data centerAssign application to most appropriate tier
Staged data migrationDeploy n-tiers of storage for one applicationBatch data movement between tiers Example: offline archives
Dynamic data movementDeploy n-tiers of storage to one applicationAutomate data movement between tiers (example: HSM)Driven by defined Data Policy

Dynamic Data Movement
Open systems: this is not just HSM anymore!Application integrated and business-driven:
Files (unstructured data)Tried and true HSM between multiple tiers of online disk-based storage, tape, optical, etc., with application transparencyNext generation data movement without HSM recall requirements
Databases (structured data)Both native and 3rd party solutions migrate transactions from production to historical storage with application transparency
Email & Messaging (semi-structured data)All email servers support interfaces that allow external management of email storage with user transparency
Policy-based: all support many policy types for data movement between tiers
Data Policies drive data movement policiesTime, user, content, etc.

• Full backup to tape takes 10 hours
– 80% inactive reduces to 2 hours!
• Full recovery takes 15 hours
