Deploy:
1) Edge Server: Allows external IM, presence,

federation with other Lync server or OC2007R2 and
XMPP federation
2) Reverse Proxy: Needed for Lync to publish
resources available on the internal network. Enables
conference join etc.
3) Director (Optional): Pre-authenticates requests and
routes it to users’ FE server or pool
1) Plan and deploy PSTN termination
2) Plan dial-in access numbers
3) Enable PSTN dial-in conferencing
Create
Simple URL?
1) Dial-in URL: Only one URL for org
2) Admin URL: Only one URL for org
3) Meet URL: Can define global or
site level URLs
1) HA requires EE pool with a
loadbalancer to distribute load
2) DR requires paired pools in 2

Topology considerations for HA
Topology considerations for DR
At least three front end servers in an
Enterprise Edition pool
Deploy pairs of front end pools across
two geographically dispersed sites
Load balancer to route traffic to front
ends
Both sites active, and the Lync Server
Backup Service provides real-time data
replication to keep the pools
synchronized.
If a server running a certain role fails, the other
servers in the pool running the same role take the
load of that server (applies to front end servers,
edge servers and mediation servers)
Backup Service is installed on a front end pool when a
pool is paired with another front end pool

Best Practices
Recommend 1 conf directory for every 999 users in the pool
Default 1 per pool
Do this at the beginning of your deployment
• You can create CAA numbers and scope them to site if you wish
however this is not exposed in the Control Panel UI
• You must create the CAA from scratch using the –scopetosite
parameter or change it after the fact using the setcsdialinconferencing cmdlet with the –scopetosite flag
• You don’t pick a site to scope it to, the CAA is scoped to the site
where you have homed the contact object
• Once there are CAA contacts present at the site level the Outlook
addin will ignore any additional numbers that are located at the
global level.
• Make sure you know what you are doing before you use this option

•

•
To ensure successful collaborative experience of meeting size > 250 it is recommended to
have a dedicated pool to host such meetings
The best practice is to create a special user account in this pool to be used only to host large
meetings
Note: It is not necessary to have dedicated File Share, Office Web Apps Server and
Monitoring Server
One Front End Server
6,660 (1,000 concurrent A/V conference users)
One Edge Server
12,000 concurrent remote users
Mediation Server
Depends on collocated or standalone mediation server
One Office Web Apps Server 1,000 concurrent users
64-bit dual processor, hex-core, 2.26 gigahertz (GHz) or higher
8 or more 10,000-RPM hard disk drives with at least 72 GB free disk space.
Two of the disks should use RAID 1, and six should use RAID 10. 1 dual-port network adapter, 1 Gbps or higher (2 recommended, which
requires teaming with a single MAC address and single IP address)
No change to audio and app sharing bandwidth in 2013
Know your network topology, typical usage patterns and utilization of existing infrastructure
Think about all possible directions for the traffic (meeting homed in organizer’s pool)
Consider external users to edge traffic, AV conf service to PSTN traffic, branch office WAN
traffic and the remainder of your internal network
Controls to use: Quality of Service (QoS), Call Admission Control (CAC), User Policies, Media Configuration
