Introduction to Information Storage and ManagementIntroduction to Information Storage and Management

Chapter 1

Section 1 : Storage System


Chapter Objectives

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

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

o Describe the value of data to business

o List the solutions available for data storage

o List and explain the core elements of data center

o Describe the ILM strategy

o Describe storage evolution


Lesson : Information Storage

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

o Describe the importance of information to individuals and to businesses

o Define data and information

o Discuss the categories of data

o Describe the storage architectures and their evolution


Why Information Storage

o “Digital universe – The Information Explosion”o 21st Century is information era o Information is being created at ever increasing rateo Information has become critical for success

o We live in an on-command, on-demand worldo Example: Social networking sites, e-mails, video and photo sharing

website, online shopping, search engines etc


Nearly a quarter of the world's population – roughly 1.4 billion people – will use the Internet

on a regular basis in 2009.


50 billion photos taken every year


Online Video

4,700,000,000 video streams monthly


England has approximately 4 million surveillance cameras

1 for approximately every 14 Britons


Storage requirements: Facebook

• 10,000,000,000 photos

• 2-3 Terabytes of photos are being uploaded to the site every day

• One petabyte of photo storage

• Serve over 15 billion photo images per day

• Photo traffic now peaks at over 300,000 images served per second

What do you Think ?

o What is your contribution to the digital Universe ( how many Mb’s have you generated till date ?? )

a) <100 GB

b) 100 GB - 500 GB

c) 500 GB – 1 TB

d) > 1 TB


What is Data

o Data is converted into more convenient form i.e. Digital Data

o Increase in data processing capabilities

o Lower cost of digital storageo Affordable and faster communication

technology

o Who creates data?o Individualso Businesses

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

Categories of Datao Data can be categorized as either

structured or unstructured data

o 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 o What do individuals/businesses do

with the data they collect?o They turn it into “information”o “Information is the intelligence and

knowledge derived from data”

o Businesses analyze raw data in order to identify meaningful trends

o For example:o Buying habits and patterns of customerso 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 Businesso Identifying new business opportunities

o Buying/spending patternso Internet stores, retail stores, supermarkets

o Customer satisfaction/serviceo Tracking shipments, and deliveries

o Identifying patterns that lead to changes in existing businesso Reduced cost

o Just-in-time inventory, eliminating over-stocking of products, optimizing shipment and delivery

o New serviceso Security alerts for “stolen” credit card purchases

o Targeted marketing campaignso Communicate to bank customers with high account balances about a special savings

plan

o Creating a competitive advantage


Storage

o Data created by individuals/businesses must be stored for further processing

o Type of storage used is based on the type of data and the rate at which it is created and used

o Examples:o Individuals: Digital camera, Cell phone, DVD’s, Hard disko Businesses: Hard disk, external disk arrays, tape library

o Storage model: An evolutiono Centralized: mainframe computerso Decentralized: Client –server modelo Centralized: Storage Networking
