WHAT IS VIRTUALIZATION?
Virtualization is a technology that allows you to transform hardware into software.
Virtualization allows you to run multiple operating systems simultaneously on a single computer.
Each copy of an operating system is installed into a virtual machine.
Virtualization is not either of these: Simulation Emulation

BENEFITS OF A VIRTUAL MACHINE
Difficult to move or copy
Bound to a specific set of hardware components
Often has short life cycle
Requires personal contact to upgrade hardware
Virtual Machine
• Easy to manage• Isolated from
other virtual machines running on the same physical hardware
• Insulated from physical hardware changes
Physical Machine• Easy to move and copy
• Encapsulated into files• Independent of physical
hardware

VIRTUALIZATION OF SERVERS
Physical Servers are typically utilized up to 12-15% ($4,500 out of $30,000)
Virtualized servers’ recommended utilization is up to 65% (some use as high as 90% - $27,000 out of $30,000!)
St. Vincent Catholic Medical Centers: Consolidation ratio of 35 virtual machines to
each physical host Nearly 85 percent of St. Vincent’s production
environment has been virtualized Savings in power and cooling costs - $3.4 million

VIRTUALIZATION OF STORAGE The availability of 100 percent for virtual servers is
highly dependent on the availability of SAN running in the background of virtualized servers.
IP-based systems provide great scalability and standards. Protocols such as FCIP and iFCP provide vast benefits to enterprise network storage systems but also have certain limitations.
iSCSI evolved a protocol that does not involve the use of any FC equipment (i.e., it is all Ethernet-based.) iSCSI simply transports SCSI commands over TCP/IP
