Top 3 Justifications for Virtualization


Technical Justifications to Implement Virtualization


1 Server Consolidation 61%

2 Reduce DC Costs 31%

3 Power Mgmnt 8%

Migration of VMs between Physical Servers


No downtime for server or storage maintenanceNo downtime if a physical server failsMove VMs when in need to power off physical servers

Migration of VMs between Storage Arrays…


Storage independent migration of

virtual machine disksZero downtime to virtual machines

LUN independent

Supported for Fiber Channel SANs

Minimizes planned or unplanned

downtime due to storage outages

Real-time Resource Scheduling


1. Improved Performance

2. Meet user demands in real-time

3. Allocate more or less resources as required to VM

4. If a physical server fails, move all VMs to another server � low-cost alternative to clustering

Power Management


Computes the required load and

available resources in the cluster

If resources are not required, free-up

and power-off physical servers

Later, if the host is required to take

user load, it is powered on via NIC

card using “wake-on-LAN” pings

Minimizes power consumption while

guaranteeing service levels

No disruption or downtime to virtual

machines

Best Practices for BCP Implementation


Why Virtualization is Effective for Disaster Recovery


Hardware-

Independence

Reliably recover a virtual machine to any hardware

Enable water falling of equipment to recovery site

EncapsulationAll information about a system is stored as data on disk

Entire systems can be protected with data protection tools

Partitioning

and

Consolidation

Reduced hardware requirements at production and DR site

Can use higher consolidation ratios at DR site

Resource

Pooling

Transparently share and allocate hardware resources

Automatic resource optimization

Virtualization Makes for a Simple, Inexpensive BCP Option

Traditional BCP solutions are complex & expensive

Most solutions tied to HW, OS, or applications

Virtualization reduces expense and

increases simplicity

HW, OS, application independent

NO need for expensive failover software

Key Components of Virtual Desktops

Centralization

� Closely managed by

Corporate IT

� Performance

� Security

� Backups

Compatibility

� Identical OS on each desktop

� Ease of upgrades

� Real-time desktop provisioning

Virtualization

� Resource Sharing

� High Uptime

� Isolated desktops

Desktop Manager

Manages connection from

client to hosted desktop.

Active Directory

For User authentication

Clients (Thin clients,

low-end desktops)Datacenter servers

provides all user desktops

Example : Before and after virtualization

Virtualization helps reduce servers, storage and network and improve utilization
