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 optimally


Introduction to Information Storage and Management

Upon completion of this module, 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


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


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

Rows and Columns

Contracts

Images

Manuals

X-Rays

Instant Messages

Forms

E-Mail Attachments

Documents

PDFs

Web Pages

Audio Video

Invoices

Rich Media

Structured (20%)

Unstructured (80%)


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

Users of Information

Centralized information storage and processing

Uploading information

Accessing information

Wired Wireless WiredWireless

Network Network

Demand for more Information

Creators of information

Virtuous cycle of information


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


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

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
