Servers: Database consolidation on Dell PowerEdge R810 servers

In this database-specific Guide, we address the consolidation of

multiple stand-alone SQL Server 2000 instances to a system

demonstrate, consolidating multiple instances to one physical

machine saves on space, hardware costs, licensing costs, power,

cooling, and administrative overhead.

Why consolidate?

An effective server consolidation effort has the potential to yield an

environment with more consistent management practices and

improved reliability, security, and hardware utilization—all while

maintaining the previous level of application performance.

Consolidation can also yield a variety of cost savings:

Hardware savings. Buying, powering, and supporting fewer

servers brings obvious savings. Other potential hardware cost

savings include the need for fewer racks and network switches: as

the number of servers decreases, these costs decrease as well.

Software license savings. Consolidation can save an

organization significant money in software licenses. We present a

detailed example of potential license savings in our earlier guide,

―Consolidating SQL Server 2000 and SQL Server 2005 databases to

SQL Server 2008 on Windows Server 2008 Enterprise on Dell

Servers.‖

Maintenance and staff savings. A consolidated infrastructure

offers many opportunities for maintenance, support, and staffing

cost savings. Less hardware and associated equipment means

fewer servers that require security patches, monitoring, and other

ongoing maintenance.

Reduced support costs. The cost of a given level of support is

typically proportional to the size of the installation. By reducing the

number of servers, support costs are also likely to decrease.

Power and cooling savings. Consolidating servers saves power

and cooling by using fewer more efficient systems.

Sizing and baseline performance

One key to a successful consolidation is sizing, the process of

gathering different performance baselines so you have an

approximate set of requirements the new hardware platform must

meet. You do this by determining the performance characteristics

of existing hardware during normal business operations, and then

applying growth and scalability estimates.
