Top 3 Justifications for Virtualization
© 2009-10 Choice Solutions Ltd. 13
Technical Justifications to Implement Virtualization
© 2009-10 Choice Solutions Ltd. 14
1 Server Consolidation 61%
2 Reduce DC Costs 31%
3 Power Mgmnt 8%
Migration of VMs between Physical Servers

Real-time Resource Scheduling
© 2009-10 Choice Solutions Ltd. 17
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

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

Why Virtualization is Effective for Disaster Recovery
© 2009-10 Choice Solutions Ltd. 20
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

Most solutions tied to HW, OS, or applications
Virtualization reduces expense and
increases simplicity
