53. What is the Lync 2013 High
Availability Model?
Problem: Solution: Lync 15 Bricks
• Front End servers manage user state
• New Lync 2013 workloads & clients • Front-end servers keep synchronous backup
(multi-view copies of their data on 3 other Front-ends.
video, XMPP, mobility, LWA) require • Front End servers and Back End databases
more server resources per user. are “loosely” coupled
• This impacts the number of users per • “Lazy writes” to the database for rehydration
Front-end server. and disaster recovery
• SQL backend is the bottleneck
preventing Scale-out - adding more
servers per Pool (> 10)
• Every transaction needs to be
committed to the Database.
• Managing HA for DB is expensive

56. High Availability - Architecture
• Lync Users are automatically mapped to “Groups”
• Each “Group” is dynamically assigned to 3 Front-end servers within a
Pool (a Primary, a Secondary and a Tertiary).
• When a user logs in, the Primary server will start servicing all of the
user’s requests.
• Changes to the user’s data (such as Contact list changes) will be
synchronously replicated to secondary/tertiary as well (3 replicas).
• If a primary server dies, then this group would fail over to the
secondary. (No data loss)
• Writes to the back-end database occur periodically (not synchronous).
• When a server dies, all the “Groups” assigned to that server as will
failover to different servers (load balancing).

57. High Availability – How does it work?
• Bob is homed on FE1 (primary)
Pool Back-end
• There are 3 copies of this user’s
data: 1 primary (FE1), 2 backups
(replicas in FE2, FE3)
• User is signed in to primary
• User’s activities, data are
replicated
• Primary goes down
• User re-signs to one of the backups
• Replicated data is available on FE2.

63. Quick overview of mirroring
Primary publisher (principal)
Secondary subscriber
Witness Server (optional, but enables
automatic failover; this is a SQL Server
High-safety mode (synchronous)
Mirroring requirements
Primary, mirror, and witness must have the
same version of SQL
Primary and mirror must have the same
edition; Witness can be different edition
Not required to have same instance name
between primary/mirror, recommended for
ease of administration/deployment

65. Manual failover (planned or no Witness)

Optional Witness Server will allow automatic failover if primary SQL Server
fails
