The Lync Server 2010 Capacity Calculator is available free of charge via the Microsoft Download Center, along with additional tools customers will need, as well as the necessary guidance. According to Microsoft, the Lync Server 2010 Capacity Calculator will streamline planning for the adoption of Lync Server 2010, especially around estimating hardware requirements.

"A spreadsheet for calculating a user's hardware requirements based on information that the admin supplies about number of users, types of communication, and expected traffic. Includes a Microsoft Word document explaining the tool and how to use it."

"You enter your organization's profile, and the calculator provides recommendations that help you plan your topology," Microsoft stated. "The recommendations created by the calculator are for planning purposes only. Actual load simulation is required to ensure that Lync Server 2010 is adequately provisioned."

"After you have determined your user profile and the modalities that you want to enable for your users, it is time to use the calculator to plan the number of servers, memory, and bandwidth that you need. This version of the calculator does not provide guidance for disk I/O requirements," the company said.

"You can benefit most from the calculator if you have accurate, detailed information about your specific user profile. For example, the percentage of voice-enabled users, average calls per user per hour, call duration, and the percentage of concurrent users in conferences can make a huge difference in server requirements. The accuracy of the recommendations created by the calculator depends on the accuracy of the information that you provide," Microsoft added.

The spreadsheet was updated in April 2011 to modify some calculated cells.

The resource is nothing more than an Excel spreadsheet, and IT professionals will need to know details such as the number of users, types of communication as well as the traffic their servers will need to support.
