Survey
“If you look at every dollar we spend in IT, somewhere
between 60 and 80 cents of that dollar is spent on
maintenance of software and operations.”
- Tony Scott, CTO of General Motors
Today’s infrastructure and operations are not
aligned with business objectives
Infrastructure is complex, brittle, inflexible
Server sprawl  underutilized servers
“One server, one app”
Diminishing hardware support for NT4
Departmental line of business server-based
applications drive operational costs
Care/feeding of application servers consumes
disproportionately high system administrator time
High cost/risk to upgrade ISV/custom applications
Customer requirements
Simplified application migration
Higher availability
Lower operational costs
Flexible server consolidation
Higher hardware utilization
Lower capital costs
Automated rapid deployment
Optimized infrastructure
Reduced total cost of ownership

Virtual Server differentiators
Support: only fully Microsoft-supported VM
solution
Standardization: no custom drivers, no
proprietary protocols; integrates with all major
management frameworks
Automation: scripted/programmatic VM
configuration, integration and management
(scripted failover, cloning, etc.)
Portability: deploy where needed, leveraging
existing storage, networking and security
infrastructures

Virtual Server virtualizes:
CPU
Memory management subsystem
Hardware the VM OS sees,
from synthetic motherboard
on up
Virtual Server emulates:
Device accesses are
trapped and emulated in
software through virtual
device models
VMs have no access to:
Host system physical
memory
Other VMs’ virtual memory
or virtualized devices
Standardization: runs every major x86
operating system
Support: Virtual Server
