Planning for OCS 2007 Part I

Alot of people ask me "How many servers do I need for OCS? How should they be deployed?" etc. The first thing to understand in deploying OCS is to understand the scenarios you want to accomplish with OCS. OCS is a very powerful software collaboration tool. Understanding the scenarios helps you understand the server roles that are required to support your configuration. So if we focus on scenarios we have the following:

  1. Instant Messaging (IM) and Presence - IM for Internal users only (Staff/Faculty)
  2. Conferencing with Audio/Video - Conferencing for Internal users only (Staff/Faculty)
  3. Remote Access Scenario for IM and Presence - IM collaboration without Barriers (Students/Staff/Faculty can collaborate) Note - all users using Microsoft Office Communicator (MOC)
  4. Remote Access Scenario for A/V and Conferencing - full collaboration without Barriers (Students/Staff/Faculty can colloborate on and off campus)
  5. Federation Scenario - setup relationships with other schools or organizations and securely collaborate with them.
  6. Public IM Connectivity (PIC) scenario - AOL/MSN/Yahoo integration with your instituation. This allows scenarios such as perspective students to talk to faculty and staff that are using MOC.
  7. Phone Control Scenario (RCC) - Remote call control - work with phone system. phone system anchors call.
  8. Enterprise Voice Scenario - OCS intiates and anchors call for users.

Sounds like alot. It is. So we need to understand how our school intends to use OCS.

So if we use the above scenarios we can start to see what servers are required to meet the scenarios needs:

  1. OCS Standard or Enterprise Edition
  2. A/V and Web Conferencing server
  3. Access Edge Server
  4. Access Edge Server, Web Conferencing Server Edge Server, and A/V Conferencing Edge Server
  5. Access Edge Server, Web Conferencing Server Edge Server, and A/V Conferencing Edge Server
  6. Access Edge Server, Web Conferencing Server Edge Server, and A/V Conferencing Edge Server
  7. 3rd party PBX
  8. Mediation Server

At this point we have started to identify servers needed for deployment. What we need next to understand what topology we need for deployment. I'll talk about that in my next post.
