• Data Freighting Clone volumes and move to
  another host on a SAN

14
Isolation Technologies

• Virtualization
• Hardware Partitioning
• Workload / Resource Management
• Virtualization
• Modeled on Mainframe VM (virtual machine)
• Guest OS is isolated
• Multiple guests per platform
• Easy to replicate, restart, manage, reset

15
Isolation Technologies (contd)

• Hardware Partitioning
• Separate OS images on some subset of total
  processors available on the system
• Intel Hardware partitioning available on Unisys
  ES7000, IBM x440
• Resource management
• Ability to assign processor and memory usage to
  applications and services in a single OS image
• Windows System Resource Manager available on
  Windows Server 2003 ES and DC

16
IIS 6 Security, Reliability Availability and
Scalability

• Security enhancements
• Run as least privileged account
• Secure defaults
• Reliability
• Worker process isolation mode
• Availability
• Process recycling
• Scalability
• 20,000 pooled applications
• Compare Less than 3000 with IIS5
• 1000 isolated apps on 1 box each with its own
  security identity
• Compare Max of 100 with IIS5
• Web Gardens support

17
Consolidation NumbersExtracted from various case
studies

• 20-30 reduction in servers
• 15 reduction in TCO thru consolidation
• 80 reduction in admin costs of providing remote
  access to mission critical applications
• 60 reduction in app dev time
• 20 reduction in management costs
• 30 reduction in servers
• 200 servers down to 160

The Consolidation ChallengeRampant Server Growth

• Over the past 5 years, organizations have been
  adding hardware (servers and storage) to their
  environments at an feverish rate
• Gartner Forecasts Worldwide Server Revenue Growth
  for 02 at 5.7 (Worst Case)
• Storage needs grow every year for most clients
  up to 100
• This behavior is driven by a number of factors
• Most Intel servers are single use servers are
  bought to support a single application, not
  multiple applications
• Capacity planning and management is limited
• Storage is primarily locally attached when
  you run out of room to add storage, you buy
  another server

Recent Server Consolidation

• Global Beverage Producer
• Customer Challenge
• Over the last few years, company x has
  experienced dramatic growth in its server
  infrastructure. The server count has grown by as
  much as 50 per year.
• Realizing that this not sustainable, company x
  requested Microsoft and Avanades assistance in
  performing a Server Simplification Assessment..
• Solution
• Implementing operational best practices in the
  context of a an overall Operations Framework such
  as ITIL
• Utilizing a leveraged / shared Development and
  Test environment for applications
• Aggressively moving to a consolidated file and
  print model
• Centralizing and centrally managing databases
• Anticipated Results
• Reduction of operational costs, reduction in
  number of servers, reduced complexity, higher
  utilization, improved availability

23
Key Findings

• Governance Issues
• Interview many
• Complexity of environment
• Balancing financial view with technical
  feasibility

24
Recent Server Consolidation

• Dow Corning
• Customer Challenge
• This enterprise-class company is confronted with
  cost control challenges in the information
  technology space for both hardware and software,
  a partially decentralized administrative model,
  and the end-of-life for Windows NT4. Dow
  Cornings CIO set a strategic vision for a
  centralized administrative model, a lower
  security risk profile, and a server reduction
  mandate.
• Solution
• Active Directory deployment Windows Server 2003
• Domain Consolidation
• Repurposing servers
• Messaging
• Application integration and migration
• Anticipated Results
• Reduction of operational costs, increase in the
  reliability and availability of system
  performance, scaleable architecture designed for
  future growth.

25
Key Findings

• Mature IT Department
• NT to Active Directory Less Servers
• Savings can be realized in mature organization

26
Best Practices

• Forward consolidation - Challenge Introduce New
  Buy New mentality
• Address non-technical issues early
• Perform assessment/analysis
• Align consolidation with technology refreshes
• Consolidate development test environments
• Quick wins vs. long-term goals
