What is Storage
 Storage is a process through which digital data
is saved within a data storage device by
means of computing technology.
 Storage is a mechanism that enables a
computer to retain data, either temporarily or
permanently.

Workflow of Storage
 Local and Client pc’s Store the data to Local
Storage and after Storage Send to Cloud
Storage to Maintain the Data.

What is Virtualization
 Virtualization refers to the creation of a virtual
resource such as a server, desktop, operating
system, file, storage or network.
 The main goal of virtualization is to manage
workloads by radically transforming traditional
computing to make it more scalable.

Why Virtualization
 Each physical hardware for each server.
 High Cost
 Power consumption
 Machine Crashing
 High Infrastructure
 Less Utilization of resource
 Down Time of a server

Types of Virtualization
1.Server Virtualization
The server administrator uses a software
application to divide one physical server
into multiple isolated virtual environments.
2. Desktop Virtualization
The major advantages of desktop
virtualization is that users are able to access
all their personal files and applications from
any location and on any PC

3. Application Virtualization
This is a process where applications get
virtualized and are delivered from a server
to the end user’s device, such as laptops,
smartphones, and tablets.
4. Network Virtualization
Network virtualization is a method that
combines all physical networking
equipment into a single resource.

5. Storage Virtualization
This type of virtualization is very easy and
cost- effective to implement, since it involves
compiling your physical hard drives into a
single cluster

Server Virtualization
 Server virtualization is the partitioning of a
physical server into several virtual servers. It is
used to maximize the server resources.
 The server virtualization technology is mainly
used in web servers.

Server Virtualization
 Server virtualization is used:
 1. to make more efficient use of server
resources,
 2. to improve the server availability,
 3. to help in disaster recovery,
 4. development and testing, and
 5. to centralize the server administration.

Storage Virtualization On
Server
 The representative of virtualisation in the
server is the combination of file system and
volume manager.
 A volume manager undertakes the separation
of the storage into logical view and physical
implementation by encapsulating the physical
hard disk into logical disk groups and logical
volumes.

Server
 Some volume managers additionally have
further storage functions such as RAID,
snapshots or dynamic reconfiguration options.
 Which permit the addition and removal or
storage during operation.

Server
 Benefits:
 Tried and tested virtualisation techniques are
generally used.
 The virtualisation functions can integrate
multiple storage systems.
 The approach remains cost effective.

Server
 Disadvantages: :
 The administration of the storage virtualisation
must take place on every single server.
 To achieve this, the appropriate software must be
installed and maintained upon the computers.
 The storage virtualisation software running on the
server can cost system resources and thus have a
negative impact upon the server performance
