Introduction to Server Consolidation
The IT Balancing Act
Many IT professionals find themselves carefully balancing many problems
simultaneously, in an attempt to prevent systems and productivity from
crashing down. Forced to respond to the disparate needs of the many
departments they support, IT specialists often struggle to meet the requests of
their organization. A common method of reacting to changing demands
involves adding equipment. This procedure often solves immediate problems,
but later reveals unforeseen consequences. Like a clumsy dance, this
balancing act tends to trickle down to one common industry problem – out of
control costs.
The Trend towards Standards
Industry wide trends reveal that most major corporations are migrating from
custom designed, proprietary platforms to more economical, standardized
systems running fewer operating systems. Beyond the obvious cost savings
are powerful benefits such as highly expandable systems and easy to use
shrink-wrapped applications. These trends stem from IT organizations’
growing need to reduce the total cost of ownership of servers, storage and
labor while maximizing processing power. Together, these trends have led to
the demand for highly available consolidated systems that enhance the ability
to respond to new business challenges.
Server Consolidation Defined – From Many to Few
Server consolidation involves optimizing resources to increase staff
productivity and reduce labor requirements, reducing total costs. Placing
systems at core locations enables IT organizations to effectively respond to
emerging business challenges, simplifies data management, reduces space
requirements and helps control the overall cost of ownership. As the world’s
largest computer supplier of Industry Standard computing platforms, Compaq
is able to provide the most reliable and cost-effective server consolidation
solutions. Compaq servers lead the industry in reliability, are designed for
optimal space utilization, and include tools that empower IT staffers with the
ultimate in manageability.
The primary benefits of consolidation involve reducing costs and increasing
reliable access to data and computing resources. Server consolidation can
help contain the following costs:
•Personnel productivity: centralized server management leverages
precious IT resources, improves response times, and decreases
server down-time
•Data control and security: server consolidation provides more
consistent and reliable access to data
•Hardware costs: equipment standardization leads to economies of
scale as maintaining smaller numbers of servers reduces overall
hardware costs
•Software licensing fees: reducing the number of servers required
to support clients means fewer application licensing fees
The act of balancing
many problems
simultaneously forces IT
organizations to be
reactive, ultimately
spiraling costs out of
control
Server consolidation
stems from the
acceptance of industry
standard systems and the
need to reduce the total
cost of ownership

Server Consolidation – Three Types
The Gartner Group identifies three different styles of server consolidation:
logical, physical and rational as tactical and workable consolidation solutions.
Logical consolidation: adopting tools that provide a centralized mechanism
for managing a set of applications. It provides operations consistency,
improves application and infrastructure reliability, increases security and
leverages precious IT talent as a business grows.
Physical consolidation: reducing the number of server and storage locations
to reduce operational costs. Also includes reducing the number of servers
and storage devices required to accomplish an organization’s computing
needs. Additionally, physical consolidation includes standardizing on a
storage environment, such as the Compaq StorageWorks Enterprise Network
Storage Architecture, to simplify day-to-day storage management, improve
economies of scale for storage purchases and easily accommodate changing
business needs.
Rational consolidation: the consolidation of applications onto fewer, more
powerful servers. Rational consolidation reduces hardware and software
expenses as well as operational overhead.
Figure 1: ProLiant server consolidation solutions address the various levels of
consolidation to different degrees.

Logical Consolidation
Organizations that may benefit from logical consolidation rely on business
critical applications such as ERP, business intelligence, e-commerce, Internet,
Intranet, mail and collaboration products. These applications are often difficult
to control and benefit from management applications that ease their
administration and reduce downtime. With logical consolidation, application
management tools improve application availability, significantly reduce
downtime and decrease IT labor costs. Logical consolidation centralizes IT
support staff and gives them the ability to manage centrally located or
distributed applications. Additionally, logical consolidation automates tasks
and applies application management across many systems at once to resolve
common problems such as disk space utilization and software updates.
Benefits of Logical Consolidation
The valuable benefits of logical consolidation include:
•Extended uptime: by proactively monitoring system resources and solving
application problems before they fail.
•Increased administrator productivity: by automating and centralizing tasks,
making it easier to maintain or improve network, systems and application
performance.
•Reduced total cost of ownership: by minimizing the number of man hours
required to perform installations, upgrades and application management.
•Improved application availability: by reducing planned and unplanned
downtime, assuring users access to network and computing resources.
•Enhanced data management capabilities: by centralizing administration of
data used in mission critical applications.
Tradeoffs of Logical Consolidation
Research has revealed that any tradeoffs of logical consolidation can be offset
if a proper solution is implemented. The primary challenges of installing
application management tools include the material costs of the management
software, the labor required to install the solution and the time needed to fully
implement a solution. An installation can take months to fully implement and
IT staffers must be trained to fully utilize the functionality of management
tools. Fortunately Compaq logical consolidation solutions, as revealed in a
major study conducted by IDC, realize a return on investment in an average of
only 77 days.

Physical Consolidation
Physical consolidation involves two types of consolidation: systems and
storage. The benefits and tradeoffs of each are unique and described as
follows:
SYSTEMS CONSOLIDATION
Organizations that may benefit from systems consolidation often have
applications and servers in separate departments, rooms and even buildings
across the globe. As systems become more distributed, managing, repairing
and upgrading them becomes more difficult and costly. Corporations need to
carefully weigh the business benefits of distribution in light of the cost benefits
of consolidation. With systems consolidation, corporations rework and
upgrade their network so that resources are located in a smaller number of
locations. Consolidating systems enables enterprise management of physical
resources from fewer locations, quick identification and resolution of problems
and it can significantly reduce overall expenses. In addition, the installation of
newer hardware and software can increase performance, capacity and fault-
tolerance of the entire infrastructure.
Figure 2: Before and after systems consolidation
Benefits of Systems Consolidation
Consolidating and upgrading systems and resources into fewer locations
provides significant benefits, including:
•Reduced costs: as a function of fewer systems performing greater tasks.
•Increased physical security: enabling all hardware to be locked and
monitored in fewer locations.
•Improved data security: as the number of platforms decrease, the access
to data can be monitored more effectively.
•Increased administrator productivity: as engineers spend more time on
server related issues and less time on non-server administrative functions,
such as traveling to remote sites to trouble shoot and upgrade systems.
•Enhanced reaction time: and proactive monitoring of systems allows
administrators to quickly solve problems, significantly reducing downtime.

management and reduce
overall expenses

ECGO30/0499
•Simplified upgrade procedures: is a function of systems in fewer locations,
reducing staffing requirements.
•Improved capacity planning: as applications may be run from fewer
servers in centralized locations.
•Increased network performance: as closer physical proximity of servers
enables high-speed connections among servers and to the network.
•Efficient use of floor space: enabling multiple servers to be stacked in a
single rack.
Tradeoffs of Systems Consolidation
There are some situations where systems consolidation may not be cost
effective. For example, if an organization’s servers are supporting extremely
remote locations (such as U.S. based servers supporting locations in Asia-
Pacific regions of the world), network infrastructure costs may outweigh the
benefits of consolidation. In addition, organizations that are distributed by
design, such as retail chains, may benefit by distributing computing resources
while centralizing the management of those resources.
There are general tradeoffs for nearly all organizations implementing server
consolidation. Significant up-front expenditures may be required to redesign
the corporate network architecture. In addition, centralizing physical
equipment opens a corporation to greater risks in disaster situations.
Additionally, when downtime does occur, it may affect a larger number of
users. Clustering and other fault tolerant features can help increase the high
availability of data. Finally, the administration staff should be prepared for
increased need for telephone support from remote users.

STORAGE CONSOLIDATION
Organizations that benefit from storage consolidation, a form of physical
consolidation, often have a dedicated and rapidly growing storage capacity for
each server in their network. Whether servers are centralized or distributed,
dedicated disk and tape volumes deter data sharing, complicate information
security, make backups more difficult to administer, and greatly increase the
cost and complexity of growing a storage farm. As the importance and
volume of data grows, continuous access becomes critical and data
management becomes more complex. Storage consolidation provides pools
of highly available, flexible and centrally managed storage that can be
distributed to provide the performance and availability demanded by
applications. In addition, storage consolidation enables organizations to
better manage growth, control security and information access, and it provides
rapid response to changing business demands.
Figure 3: Storage Consolidation allows multiple servers to access a shared
storage repository
Benefits of Storage Consolidation
Storage consolidation provides numerous benefits to organizations, including:
•Highly scaleable storage: enabling administrators to manage growth and
quickly respond to changing business needs.
•Highly available and fault tolerant storage: providing continuous and
reliable access to data.
•Improved data management: and protection from consolidated storage.
•Increased storage utilization: from allocating storage via a centrally
managed pool of storage.
•Reduced administrative costs: and time required to troubleshoot problems.
•Platform independence: enabling sharing of data and simplified backup
procedures.

Tradeoffs of Storage Consolidation
Storage consolidation’s numerous benefits also include a few notable
tradeoffs. It is important to consider disaster recovery scenarios when data is
centralized to a single location. In addition, storage engineering and
application configuration expertise is required to adequately analyze network
performance requirements. Storage consolidation may require a significant
initial cash outlay to procure large RAID units as opposed to simply adding
hard drives to a system. In addition, existing investments in RAID and tape
backup may become obsolete as they are replaced by larger arrays and
automated tape backup libraries.
Benefits of Using Compaq for Storage Consolidation
A primary reason to consider Compaq for your storage consolidation efforts is
that Compaq is the world’s largest storage supplier. Compaq is also the only
storage vendor that ensures high availability and reliability, high capacity and
high performance storage, with solutions for applications ranging from the
desktop to the data center. Other benefits include:
•Compaq’s Enterprise Network Storage Architecture (ENSA) provides a
highly flexible environment for data storage capacity and management.
This advanced technology creates “virtual disks” from a large pool of
consolidated storage. The storage pool is physically distributed as
business needs require. With ENSA, a storage pool can consist of a
number of small, relatively inexpensive “array controllers” that are
deployed as needed. Storage growth is granular down to a disk drive. In
addition, ENSA preserves much of today’s storage hardware investment.
Only ENSA offers the range of configuration, performance tuning,
monitoring and data protection capabilities needed to unify an enterprise
storage environment. ENSA is also designed to grow as business needs
require, while maximizing the protection of your existing storage
investments.
•StorageWorks Command Console, a Windows NT based monitoring and
configuration tool, can manage up to 1.2 petabytes of data distributed
across an enterprise from a single workstation. Its easy to use features
include failure notification, reliability monitoring and multiple levels of

Rational Consolidation
Organizations well suited for rational consolidation have experienced dramatic
growth that resulted in complex solutions for workload related tasks.
Situations such as corporate mergers and global expansions create
redundant, incompatible workgroup practices, including financial applications,
office productivity tools, intranet applications, e-mail and customer
management applications. Rational consolidation merges different workgroup
applications onto standardized enterprise applications, running on fewer and
larger servers, optimizing labor usage and reducing overall costs.
Benefits of Rational Consolidation
The many benefits of rational consolidation include:
•Increased administrator productivity: by standardizing on fewer servers
and reducing the number of applications that are required.
•Reorganization of complementary resources: into a singular workflow
environment (e.g. order entry and general ledger).
•Decreased downtime: in a centralized single application environment
because problem-resolution capable staff are locally accessible.
•Reduced application licensing fees: as a single application replaces the
workload of many applications.
•Increased resource utilization: in large scale global environments because
fewer servers are operating for longer periods of time, as opposed to
many servers being under-utilized.
•Reduced total cost per user: as a function of decreased hardware,
software and overhead expenses.
Rational Consolidation Example
In 1995, Digital Equipment Corporation evaluated its global
staffing and equipment requirements for its e-mail application
servers. The company found there were 700 staffers attending to
mail servers around the globe. After consolidating on a single e-
mail application, Digital was able to eliminate nearly fifty
percent of its e-mail servers and reduce dedicated support staff to
200. In 1997, the company handled 50 million messages per day
at a cost thirty-five percent less than it did in 1995.

tasks into fewer, more
powerful systems and
applications

Tradeoffs of Rational Consolidation
Consolidating workload activities presents notable tradeoffs that must be
appropriately planned for. A major challenge when centralizing workloads is
the requirement for increased fault tolerance. A failure or even planned
downtime in a consolidated environment can affect a great number of
individuals and have an adverse effect on the productivity of an entire
organization. Equipment must be highly reliable and fault tolerant to minimize
failures. Organizations considering rational consolidation need a plan to deal
with backup and planned downtime. In addition, rational consolidation may
place a larger burden on the staff supporting remote users. Additionally, as a
function of current operating systems, the ProLiant platform has limited
capabilities when operating multiple applications on a single server. Compaq
AlphaServer and Himalaya platforms may be better suited for more intensive
rational consolidation efforts. The net benefit of any rational consolidation
effort is a streamlined IT infrastructure that can better leverage the IT staff
while assuring greater reliability for the users and lower capital costs for the
corporation.

Summary
Forced to respond to the disparate needs of the many departments they
support, IT staffs often struggle to meet the needs of their organization.
Industry trends have revealed a demand for centrally managed highly
available systems that reduce administration costs and enhance the ability to
respond to new business challenges. Server consolidation meets these
needs head-on by consolidating operations to reduce total costs.
There are three types of consolidation efforts that address unique concerns
within a typical IT department: logical, physical and rational. Logical
consolidation is the centralization of application management tasks to
increase uptime and IT staff productivity. Physical consolidation consists of
two types of material consolidation, systems and storage. Systems
consolidation is the centralization and updating of server resources to fewer
locations to reduce operational costs. Storage consolidation is the
standardization on a disk and tape storage platform to reduce operational
overhead and increase data availability. Rational consolidation is the
consolidation of applications onto fewer, more powerful servers, to curtail
hardware and software expenses as well as operational overhead. Together,
these three categories of consolidation can significantly reduce costs and
increase a corporations overall productivity levels.
Compaq Computer Corporation is well positioned to meet all of your server
consolidation requirements. As the market leader of Intel based industry
standard servers, Compaq offers an unparalleled array of services and
equipment to aid in your consolidation efforts. If you need absolute reliability,
