Server and Data Center Consolidation
Microsoft IT enhances cost savings, availability, and performance
Published: June 2004
Solution Overview
Situation● Microsoft IT needed to reduce enterprise complexity and costs
Solution● Improve IT operational efficiency, while reducing TCO
● Develop site taxonomy and Minimum Performance Level system● Implement ICOs ● Consolidate servers and data centers ● Centralize server management● Institute new operations practices and procedures
Benefits● Data center, server consolidation: 37% reduction in spending● Site reduction: 54 percent● Infrastructure server reduction: 27%● Data centers: rent and maintenance reduced by 50%
Excessive Complexity and Costs
● Too many data centers and servers● Central management function not
optimized● Duplication of storage, applications, and
hardware● Inconsistent levels of support● High rent and maintenance costs
Business Value
● Total $23.2 million in savings to date● 40% reduction
● Server and Data Center consolidation● $18.3 million reduction
● Internet Connected Offices● $4.5 million savings● Enhanced time to market
Business Value
● Infrastructure Server Consolidation● Savings of $4.3 million
● Centralized Server and Data Management ● Incident Management team of 22 supports
10,000 servers worldwide
● New Operations Practices and Procedures
Catalysts and Background
● Key Catalysts:● Hardware improvements● Decreased communication costs● Backbone bandwidth● New connectivity options● Product improvements● Exchange infrastructure consolidation
Catalysts and Background
Sever Consolidation Glossary● Logical: server management, centralized
management of business critical systems and applications
● Geographic: closing of data centers, and implementing ICO offices
● Homogenous: scalability of Microsoft products
● Heterogeneous: different applications from multiple servers onto one server
Server and Data Center Consolidation Strategy● Systematically develop a layered tier
system, or taxonomy, of IT service sites● Define service levels that are provided
at those sites● Ensure consistency with the business
requirements of the services that the sites support
● Begin ICO, consolidation activities
Server and Data Center Consolidation Strategy
Site Number of People
Primary Site Purpose
Network Servers
Data Center 1 or 2 N/A IT Infrastructure Requires at least redundant circuits
Servers on-site
High Availability Office
N/A PSS Call Center, Network Hub, or other valid business need
Requires diverse access (2 paths)
Consolidate servers to the Data Center where you can meet MPL
Standard Office 50 and greater N/A Poor ISP and/or requires more bandwidth than DSL
Consolidate servers to the Data Center where you can meet MPL
ICO-2 (Persistent Connection)
20-150 Sales & Marketing Good ISP, requires more bandwidth than DSL
Consolidate servers to the Data Center where you can meet MPL
ICO-2RP (Persistent Connection, Regional Provider)
20-150 Sales & Marketing Good ISP Consolidate servers to the Data Center where you can meet MPL
ICO-1 (Smart Card) 1-20 Sales & Marketing Good ISP None

Server and Data Center Consolidation Strategy● MPL development – differs from SLA
● MPLs are relative measures of performance when a service is available
● MPLs are generally expected to be met 100 percent of the time
● SLAs are strictly measures of service availability
● SLAs are generally expected to be met 80 percent of the time
Server and Data Center Consolidation Strategy● Internet Connected Offices
● Eliminate private network connection, remove office servers
● Significant savings – take advantage of less expensive network bandwidth
● Provides computing experience equivalent to local server environment
● Three levels of ICOs
Server and Data Center Consolidation Strategy● ICO-1 (Smart Card)
● ISP provides ICO site’s Internet connectivity
● Client systems access corpnet through VPN (PPTP)
● ICO-1 is not managed centrally● Intended for offices of 20 employees or
less
Server and Data Center Consolidation Strategy● ICO-2RP (Persistent Connection,
Regional Provider)● Carrier is an in-country or in-region
provider● Carrier is not managed by Microsoft IT
Carrier Strategies team● In many cases the carrier is designated by
the local government● Level of support is not guaranteed
Server and Data Center Consolidation Strategy● ICO-2 (Persistent Connection)
● Requires a persistent, tunneled connection to the Internet
● Smart card not required to log on ● More costly than ICO-1 due to specialized
equipment● Centrally managed● Targeted for sales and marketing offices with 20 to
50 employees
● ICO Implementations fast and straightforward
Server and Data Center Consolidation Strategy● Regional data centers reduced from 24 to 11● Large data centers responsible for full range
of services including backup and disaster recovery
● Smaller data centers responsible for services associated with latency
● Cost avoidance issues● Iterative approach to consolidation
Infrastructure Server Consolidation Strategy● Wide variety of infrastructure server
types● Consolidating domains with Windows
Server 2003● Higher workloads on fewer servers● Greater directory control and flexibility
● Consolidation allowed infrastructure servers to be repurposed
Infrastructure Server Consolidation Strategy
Before Consolidation After Consolidation
●203 domain controllers●48 domain controllers in corporate headquarters
●138 domain controllers ●36 domain controllers in corporate headquarters
● Domain Controller Consolidation
Infrastructure Server Consolidation Strategy● WINS, DHCP, DNS, ISA, Proxy Servers
● WINS and DNS required assigning new static IP addresses
● User communication paramount● DCHP service consolidated onto regional
domain controllers● Use of secondary networks eases transition
● ISA and Proxy servers were removed at beginning of ICO implementation
● User impact high priority consideration
Centralized Server Management Strategy● 22 people manage incident support for
approximately 10,000 servers● Remote support team was in-sourced● 25% service SLA improvement● Standard service offerings provided for
all production servers
New Operations and Procedures Strategy● Incident management practices enhanced
monitoring ● Problem management practices resolved
recurring service issues● Configuration management practices defined
standards by which devices are tracked, configured, and accepted
● Change management process revised the way changes are reviewed and implemented
Future
● Next target is application servers● BUIT application support● Represents 75% of all the systems in
Microsoft IT● Program will focus on:
● 64-bit computing● Virtual Server● Dynamic Systems Initiative● Windows System Resource Manager
Conclusion
● Server and data center consolidations very successful at Microsoft
● Reduction of 40% ($23.2 million) in costs
● Opportunity to align IT infrastructure with business strategy
● Meeting future demands as well as immediate needs
