run at 50-60% utilization. Excess or underutilized capacity on one server cannot be shared with workloads of other servers in a distributed environment.

Optimization of skilled resources - Under the distributed alternative, systems management responsibilities are often only part-time, extra-duty assignments such that a critical skill level is rarely achieved. Furthermore, since other departments may employ disparate architectures and applications, there is little opportunity to benefit from the experiences of others.

￿Scalability and workload growth

Server consolidation can help you handle scalability and workload growth issues in the following ways:

True scalability - Server consolidation provides the ability to deal with peak usage without crashing or seriously degrading performance. It also provides an upgrade path without degradation in response, excessively complex forms of database partitioning, or other problems.

Granular upgrades - Server consolidation provides the ability to quickly grow the number of users, the number of applications, or the size of an application when needed, without major disruptions to the current production environment.

￿Service level

Most companies spend their IT budget for services. They need services for hardware, software, and infrastructure maintenance. Server consolidation can help you to reduce the increasing service costs in the following ways:

Delivery of a specified service level is costly if servers are uncontrolled.

Management of servers as corporate assets is easier when they are centralized.

Application deployment is quicker and easier when not spread over a large number of servers.

Staff time freed from server maintenance tasks can be used for activities more directly related to business needs.

￿Business continuity

Almost all enterprises need to run their business without interruption. Business interruption can be very costly and it influences the productivity of your business. Server consolidation can help you to run your business without interruption in the following ways:

Consolidating IT resources can help you ensure that critical business information and processes are accessible and shared across the enterprise.
