Leveraging Virtualization
Technologies for IT Optimization
Virtualization provides the user with an abstracting layer of
logical server, file and storage from physical hardware,
computing power and storage which therefore hides the
physical complexity and conditions of the hardware.
Reasons for using Virtualization Technologies:
Virtualization concept
are often compared with a server virtualization. However,
not all virtualization solutions exist on servers but
instead exist on far more levels of the IT
infrastructure.
Our solutions offer you a class of virtualization
technologies and services that help you transform and
manage your infrastructure more efficiently and respond
to the changing needs of your day-to-day business. Itiso’s virtualization solutions help you meet your
critical server, file and storage requirements and
deliver on the true potential and benefits of
virtualization.
Itiso makes use of various types of virtualization
technologies. The following examples describe the
various types of virtualization tools and its advantages.
Application
Virtualization
Application
virtualization decouples applications from the operating
system and enables them to run as network services. The
general purpose of application virtualization is to
separate application code from the restrictions of
individual servers, operating systems and clients.
Because the applications are never permanently loaded on
the client, license requirements apply only to the
central application virtualization server. Applications
from remote servers can run locally without changes to
the local environment and multiple versions of an
application can run on the same client concurrently.
Server Virtualization
Server
Virtualization enables multiple virtual
operating systems to run on a single physical
machine, yet remain logically distinct with
consistent hardware profiles. The advantages of
server virtualization is minimize new hardware
acquisition by hosting several virtual servers
on one physical server, migrate data and
applications among servers more quickly and
efficiently, increase real processor usage on
your existing physical servers and ease of
administration.
File-Virtualization
File
virtualization enables multiple files or objects
to appear as a single file and enables
administrators to move files transparently
without affecting end users or applications.
File virtualization allows tired storage
management which can trigger or uses
frequency-of-access data for relocation from
higher cost to lower cost, nearline storage.
File-System-Virtualization
With the
help of file system virtualization, high-performance NAS
systems can provide automated data storage and delivery
services across a wide range of enterprise platforms.
The advantages of file system virtualization is to
provide unlimited, on-the-fly bandwidth and capacity
scalability in a cluster, multi-platform NAS environment
with using standard, off-the-shelf hardware.
File-Server-Virtualization
File server
virtualization makes it possible to consolidate several
file servers within a system environment. In the
prospective of the end-user, nothing changes and there
is no special requirement for storage hardware. This
approach can be used practically on any type of
supported SAN storage. Additionally, advantage includes
integrated cluster functionality, high performance,
snapshots and replication as well as low consumption of
electricity.
Storage-Virtualization
Storage
Virtualization is the pooling of physical
storage from multiple network storage devices
into what appears to be a single storage device
that is managed from a central console and helps
perform the tasks of backup and recovery more
easily, and in less time, by disguising the
actual complexity of the SAN and deliver data
services, as in replication, snapshots,
mirroring and data migration.
Tape-Virtualization
A Virtual Tape Library is an archival backup
solution that combines traditional tape backup
methodology with low-cost disk technology to create an
optimized backup and recovery solution. It is an
intelligent disk-based library that emulates traditional
tape devices and tape formats. Acting like a tape
library with the performance of modern disk drives, data
is deposited onto disk drives just as it would onto a
tape library, only faster. Virtual tape backup solutions
can be used as a secondary backup stage on the way to
tape, or as their own standalone tape library solution.
To address the unique requirements of long-term data
storage, MAID (Massive Array of Idle Disks) would be an
option to consider. In a virtual tape library
environment with MAID, faster restore time,
significantly reduction in backup time, significant
savings in power and large reductions in generated heat
can be achieved.
