Abstract
ƒ Data center migration and consolidation is a major undertaking that
involves many different, often complex, components and technologies
ƒ Careful planning is a critical phase during which a solid
understanding of existing infrastructure and all associated
environments is required
ƒ This session helps data center managers and engineers identify focus
areas and presents an overview of the discovery methodologies used to
identify critical data center components like facilities, WAN, LAN, security,
and applications, in both their physical and logical aspects
ƒ The session highlights different tools and matrices that can be used
to extract important information that is crucial to a successful
migration/consolidation project
ƒ Information gathered from the discovery can be used to create a migration
or consolidation strategy that leads to a new architectural design and
account for all aspects of existing environments

Before We Get Started:

ƒ Intermediate level session focused on gathering
of essential data for planning a data center
consolidation or migration project
ƒ Session is about discovery of DC components,
not necessarily solutions
ƒ Other recommended sessions: TECDCT-2887

Consolidation—Flavors

ƒ Existing site or green field
ƒ Single site consolidation—in place consolidation
ƒ Multiple site consolidation—from many to few
Reducing number of datacenters
Migrating infrastructure components to fewer
locations, without any optimization

Migration + optimization
Reducing the number of infrastructure components
and increasing resource utilization

Take Away Points

Session_ID
Presentation_ID © 2008 Cisco Systems, Inc. All rights reserved. Cisco Public 59

Take Away Points

• Data Center migration & consolidation is a complex
process with complex end-to-end dependencies. It can be
broken into easier to manage components

• Start with understanding and profiling the applications
thoroughly

• L2 – L7 components dependent on business policies and
application requirements. Be aware of facilities planning

• Leverage available tools to discover different components,
specially in legacy environments

Case Study – The landscape

ƒ Existing data center with more than 1,600 servers
ƒ Data center hosts services for 15 different business
units
ƒ Silos within the data center. Some business units
sharing the service modules, others have their own.
ƒ No single policy or procedure to connect to new
partners

Case Study – New Data Center
ƒ New Data Center built 60 miles apart
ƒ Based on three tier architecture: Web, Application,
Database to be shared among Bus
ƒ Web, application and database tiers in separate
security zones
ƒ Number of physical servers reduced to 700 plus.
ƒ Consolidation of services (load balancing, security,
partner connections)
