Prerequisites

You must have already collected data on the systems of interest (see

“Gathering data for

Capacity Advisor” (page 59)

).

You should be familiar with Capacity Advisor operations (see

“Procedures” (page 59)

).

You must be logged in to Matrix Operating Environment (see

“Accessing Capacity Advisor”

(page 59)

).

Determine which systems to consolidate (both to
and from).

“Creating a planning scenario” (page 86)

Create a planning scenario.

Run reports on the scenario systems.

set of reports to compare your scenario changes

Edit the scenario copy:

or

system” (page 94)

Set up the new VM host system.

Modify resources on systems as needed.

“Editing a system” (page 94)

Make each system to be consolidated become
a VM.

“Changing servers to be VMs (manually)” (page 96)

Modify utilization limits, if desired.

Evaluate new quality of service

“Creating a cost allocation report” (page 76)

Estimate new cost allocation on the VM host

Example consolidation: Stacking applications on an existing server

This example demonstrates how Capacity Advisor can be used to simulate converting physical
servers to virtual machines, and to then stack those VMs onto one VM host.

Assume that you have a set of legacy servers that currently support one application each. There
is good data on resource utilization for each of these servers, and it is time to see if converting
these application servers into VMs and then consolidating the VMs onto fewer VM hosts can free
up resources for other uses. For purposes of this example, it is assumed that the applications will
each run in their own virtual machine.

This task requires a profound knowledge about the systems.

What are the licensing requirements for the applications?

Who owns each of the systems and, if they are owned by different organizations, are they
agreeable to the consolidation?

What are the security requirements?

What are the networking requirements (LAN and WAN)?

Are there Storage Area Network (SAN) requirements?

How stable are the applications? All of them should be test and development systems or
production systems.

This list is illustrative; other questions may need to be answered for your particular environment.
