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, searchengines etc
Information management is a big challenge Organization seek to Store , Protect, Optimize and
Leverage the information optimally.

What is DataCollection of raw facts from which conclusions may be drawn
Most data is beingconverted into a digital
format
Driven by user demand
Facilitated by Increase in data processing
capabilities
Lower cost and increased
speed of storage
Affordable and faster
networks
Who creates data?Individuals
Businesses

Categories of Data
Data can be categorized as either structured or unstructured data
Structured:
Data Bases
Spread Sheets
Unstructured
Forms
Images
Audio

Over 80% of enterprise
Information is unstructured
Contracts
Images
Manuals

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

Storage
Data created by individuals/businesses must be storedfor further processing
Type of storage used is based on the type of data andthe rate at which it is created and used
Examples: Individuals: Digital camera, Cell phone, DVDs, Hard disk
Businesses: Hard disk, external disk arrays, tape library
Storage model: An evolution
Centralized: mainframe computers Decentralized: Client server model (Data spread across many
servers)
Centralized: Storage Networking (Hugh respositories)

Example of a Data Center
Infrastructure
Consider an order processing system consisting of:
Application for order entry
Database Management System (DBMS) to store customer and product information
Server/Operating System (OS) on which the application and database programs are run
Networks that provide
Connectivity between Clients and the Application/Database Server (LAN)
Connectivity between the Server and the Storage system (SAN)
Storage Array database is stored on physical disks in the storage array

Process Flow
A customer order is entered via the Application UserInterface on a client.
The client accesses the server over a Local Area Network
A DBMS uses the operating system on the server to read
and write this data to the physical location on a disk A dedicated Storage Area Network provides the
communication link between the server and the storagearray, and transports the read/write commands and databetween the server and the storage array
A storage array receives the read/write commands anddata from the server and performs the necessaryoperations to store the data on the physical disks

Challenges in Managing Information
Exploding digital universe
Multifold increase of information growth
Increasing dependency on information
The strategic use of information plays
Changing value of information
Information that is valuable today may become
less important tomorrow.
