The first part of the planning process is deciding which Microsoft Lync Server 2010 workloads and major features you want for your organization.
- Do you want a physical or virtualized
topology? Microsoft Lync Server 2010 supports
all workloads and server roles in both physical and virtualized
topologies. User capacity in a virtualized topology is roughly 50
percent of the capacity in a physical topology. For details, see
Running in a
Virtualized Environment in the Planning documentation.
- Instant messaging (IM) and presence are always
enabled. In any Lync Server deployment, the
instant messaging (IM) and presence workload is installed and
enabled by default. IM enables your users to communicate with
real-time text messages, and presence enables them to see the
status of other users on the network. A user’s presence status
provides information to help others decide whether they should try
to contact the user, and by what means. For details, see Planning for IM and
Presence in the Planning documentation.
- Do you want to deploy any modes of
conferencing? Conferencing is another core
feature of Lync Server. Several modes of conferencing are
supported. You can choose to deploy all supported types of
conferencing, or just some of them. Web conferencing enables
users to see a file, such as a slide deck created with Microsoft
PowerPoint presentation graphics program, that is being presented.
Application sharing enables users to share all or part of
their desktop with each other in real time. With A/V
conferencing, users can add audio (and possibly video) to their
conferences and peer-to-peer communications. Dial-in
conferencing enables users to use standard PSTN phones to join
the audio portion of conferences hosted at your organization. For
details, see Planning for
Conferencing in the Planning documentation.
- If you deploy A/V conferencing, you should also monitor the
audio quality of these conferences. Many
factors affect the audio and video quality of Lync Server A/V
conferences. By using the A/V quality monitoring features provided
by the Monitoring Server role, you can detect issues that affect
media quality, and ensure that your users have the best possible
- Do you want high availability for your IM, presence, and
conferencing servers? If you have only one
server at a site providing IM, presence and conferencing features,
your users’ productivity will be greatly affected if that server
goes down. By deploying a pool of multiple servers for these
functions, you make it possible for Lync Server to continue
functioning with all of these features intact even if a server is
unavailable. Additionally, if you have more than 12,500 users at a
site, you must deploy a pool to serve this large number of users.
This pool also provides high availability.
- Do you want to deploy Enterprise
Voice? Enterprise Voice is the voice
over IP (VoIP) solution provided by Lync Server. It provides an
attractive alternative to traditional PBX-based telephony.
Enterprise Voice enables users to place calls from their computers
or VoIP phones by clicking a contact in Outlook or Microsoft Lync
2010. They can place calls over the IP network from computer to
computer, computer to telephone, or telephone to computer. Users
benefit from having all of their communications options-voice,
email, IM, and conferencing-available and integrated on their
computers. For details, see Planning for Enterprise
Voice in the Planning documentation.
- If you deploy Enterprise Voice, you should also monitor the
audio quality of these calls. We recommend you
use Monitoring Server to ensure the audio quality of your
Enterprise Voice calls, if you deploy Enterprise Voice.
- Do you want to deploy Exchange UM? If
your organization uses Microsoft Exchange Server for its email
services, you can deploy the Exchange Unified Messaging (UM)
features of both Microsoft Exchange and Lync Server to enhance
communications capabilities for your users. Exchange UM features
include enabling users to receive voice mail notices and listen to
voice mail from Outlook or Outlook Web Access, to access their
Microsoft Exchange mailboxes using a telephone, and to receive
faxes in their Microsoft Exchange mailboxes.
- Do you need to archive IM content or meeting content for
compliance purposes? If your organization has
to archive IM content or meeting content for compliance purposes,
you can deploy an Archiving Server.
- Do you want to enable your users to communicate and
collaborate with external users? Enabling
communication and collaboration with external users can increase
your return on investment in Lync Server. This enables your
organization’s own users to benefit from Lync Server features even
when they are working outside your organization’s firewalls. You
can also federate with your partner or customer organizations that
run Lync Server. By doing so, your users and federated partner
users can easily send and receive IM messages, invite each other to
meetings, and see each other’s presence. Additionally, your users
can use an email message to invite specific outside users to
conferences that they organize.
- Do you have branch offices in your
organization? If your organization has branch
offices, Lync Server 2010 supports a variety of ways to support
them and ensure their resiliency for voice and other features. In
particular, at a branch office that does not have a resilient WAN
link to a data center, you can install a Survivable Branch
Appliance or Survivable Branch Server to maintain Enterprise Voice
support should the wide area network (WAN) link go down. For
details, see Enhanced Voice
Resiliency in Central Sites and Branch Offices in the Planning
