Introduction to Information Storage and Management

Chapter 1


3

Why Information Storage• “Digital universe – The Information Explosion”

– 21st Century is information era – Information is being created at ever increasing rate– Information has become critical for success

• We live in an on-command, on-demand world– Example: Social networking sites, e-mails, video and

photo sharing website, online shopping, search engines etc

• Information management is a big challenge– Organization seek to Store Protect Optimize

Leverage the information


4

Chapter Objective

Upon completion of this chapter, you will be able to:

• Describe who is creating data and the amount of data being created

• Describe the value of data to business• Describe storage technology and architecture

evolution • List and explain the core elements of data center• Describe the ILM strategy


5

Lesson: Information Storage

Upon completion of this lesson, you will be able to:

• Describe the importance of information to individuals and to businesses

• Define data and information

• Discuss the categories of data

• Describe the storage architectures and their evolution


6

What is Data

• Data is converted into more convenient form i.e. Digital Data– Increase in data processing

capabilities– Lower cost of digital storage– Affordable and faster

communication technology

• Who creates data?– Individuals– Businesses

“Collection of raw facts from which conclusions may be drawn”

Categories of Data

• Data can be categorized as either structured or unstructured data

• Over 80% of enterprise information is unstructured

Define Information • What do individuals/businesses

do with the data they collect?– They turn it into “information”

– “Information is the intelligence and knowledge derived from data”

• Businesses analyze raw data in order to identify meaningful trends– For example:

• Buying habits and patterns of customers

• Health history of patients

Value of Information to a Business

• Identifying new business opportunities– Buying/spending patterns

• Internet stores, retail stores, supermarkets– Customer satisfaction/service

• Tracking shipments, and deliveries• Identifying patterns that lead to changes in existing business

– Reduced cost • Just-in-time inventory, eliminating over-stocking of products,

optimizing shipment and delivery– New services

• Security alerts for “stolen” credit card purchases– Targeted marketing campaigns

• Communicate to bank customers with high account balances about a special savings plan

• Creating a competitive advantage


10

Storage• Data created by individuals/businesses must be stored

for further processing• Type of storage used is based on the type of data and

the rate at which it is created and used• Examples:

– Individuals: Digital camera, Cell phone, DVD’s, Hard disk

– Businesses: Hard disk, external disk arrays, tape library

• Storage model: An evolution– Centralized: mainframe computers– Decentralized: Client –server model– Centralized: Storage Networking

Challenges in Managing Information

• Exploding digital universe– Multifold increase of information growth

• Increasing dependency on information– The strategic use of information plays an

important role in determining the success of a business

• Changing value of information– Information that is valuable today may

become less important tomorrow.

Benefits of Implementing ILM• Improved utilization

– Tiered storage platforms

• Simplified management – Processes, tools and automation

• Simplified backup and recovery– A wider range of options to balance the need for business

continuity

• Maintaining compliance – Knowledge of what data needs to be protected for what length

of time

• Lower Total Cost of Ownership – By aligning the infrastructure and management costs with

information value
