Consolidating multiple SQL Server systems onto

Dell PowerEdge R610 Servers using Microsoft’s Hyper-V

Generally speaking, consolidation refers to the process of

combining multiple things to make a single, more effective unit. In

this Guide, we discuss combining the concepts of virtualization and

consolidation to achieve your overall goals.

In an IT context, you can consolidate several types of things,

including the following:

Physical servers. In this Guide, consolidation typically means

consolidating servers. After a successful consolidation, all

applications should run on fewer servers than before, and those

applications should run at least as well as they did previously. The

other types of consolidation we mention below may happen as a

consequence of consolidating physical servers, but they are not our

primary focus.

Storage. As you follow the procedures in this Guide, you will

consolidate storage to some degree by moving software and data

from a number of servers to a large, locally attached, disk storage

subsystem in a new server in the form of virtual hard drives.

• NOTE: Although we will be implementing a 1.79TB SAN in

this Guide, large-scale storage consolidations are outside

the scope of this Guide.

Locations. As you consolidate servers through virtualization, you

may reduce the number of locations you need for servers. Planning

for consolidating geographic locations is also beyond the scope of

this Guide.

This Guide focuses on consolidation via virtualization. For details

about consolidation at the SQL Server instance or database level,

see our earlier Guide, “Consolidating SQL Server 2000 and SQL

Server 2005 databases to SQL Server 2008 on Windows Server

2008 Enterprise on Dell Servers”

Why consolidate?

Done well, consolidation yields a more economical environment

with more consistent management practices, better use of

hardware, and all applications performing at least as well as they

did previously. An effective consolidation effort improves reliability

and security while bringing great savings to your organization.

Some of the ways consolidation can stretch your technology dollar

include the following:

Hardware savings. Buying, powering, and supporting fewer

servers brings obvious savings to your organization. Less obvious
