The world’s information is doubling every two years. In 2011 the world created a staggering 1.8 zettabytes. By 2020 the world will generate 50 times the amount of information and 75 times the number of "information containers", while IT staff to manage it will grow less than 1.5 times. This session introduces students to various storage networking, & business continuity terminologies.

3. Why Information Storage and Management?
• Information is the knowledge derived from data
• Growth of digital information has resulted in information
explosion
• We live in an on-command, on-demand world
 We need information when and where required
• Increasing dependency on fast and reliable access to information
• Businesses seek to store, protect, optimize, and leverage the
information
 To gain competitive advantage
 To derive new business opportunity

4. Data Center
Data Center
It is a facility that contains storage, compute, network, and other IT
resources to provide centralized data-processing capabilities.
• Core elements of a data center
 Application
 Database management system (DBMS)
 Host or Compute
 Network
 Storage
• These core elements work together to address data-processing
requirements

6. Host (Compute)
• Resource that runs applications with the
help of underlying computing
components
 Example: Servers, mainframes, laptop,
desktops, tablets, server clusters, etc.
• Consists of hardware and software
components
• Hardware components
 Include CPU, memory, and input/output IP
(I/O) devices
• Software components
 Include OS, device driver, file system,
volume manager, and so on

9. Intelligent Storage System (ISS)
Intelligent Storage System
It is a feature-rich RAID array that provides highly optimized I/O processing
capabilities.
• Provides large amount of cache and multiple
I/O paths that enhances the performance
• Has an operating environment that provides
 Intelligent cache management
 Array resource management
 Connectivity to heterogeneous hosts
• Supports flash drive, virtual provisioning, and
automated storage tiering

11. Storage Area Network
SAN
It is a high-speed, dedicated network of servers and shared storage devices.
• Centralizes storage and management
• Enables sharing of storage resources across multiple servers at
block level
• Meets increasing storage demands efficiently with better
economies of scale
• Common SAN deployments are:
 Fibre Channel (FC) SAN: uses FC protocol for communication
 IP SAN: uses IP-based protocols for communication

12. Understanding Fibre Channel
• High-speed network technology
 Latest FC implementation supports speed up to 16 Gb/s
• Highly scalable
 Theoretically, accommodate approximately 15 million devices

15. Network Attached Storage
NAS
It is an IP-based, dedicated, high-performance file sharing and storage device.
• Enables NAS clients to share files over IP network
• Uses specialized operating system that is optimized for file I/O
• Enables both UNIX and Windows users to share data

17. Business Continuity
• Information is an organization’s most important asset
• Continuous access to information ensures smooth functioning of
business operations
• Cost of unavailability of information to an organization is greater
than ever
