Lync 2010 Resiliency Architecture

▪ Registrar Component▪ Registration and Routing▪ Each registrar has its SQL Express DB

▪ User Services Component▪ Presence & Conferencing

▪ Registrar and User Services are collocated in same physical Front End in the DC

▪ All user end points register with same registrar

▪ Users are load balanced by Registrars using a Distributed Hash Algorithm

▪ Registrar can be installed in remote locations

Agenda• Introduction• On Premises – Online• Lync = Puzzle• Pictures• NAT?• Tools?• Monitoring

Lync 2010 and My Picture

• Lync can display photo• ADDS: thumbnailPhoto

(SharePoint/Exchange)• URL (JPEG & publically readable)

• thumbnailPhoto• Introduced in Active Directory 2000• Default size is 100Kb (EMS limits to 10Kb)• Requires Outlook 2010 and a forest schema

extended to the 2008 version or later• Replicate to Global Catalog

Lync 2010 and My Picture• Controlling = CsClientPolicy

• DisplayPhoto• MaxPhotoSizeKB (default = 30Kb)

• Not stored in GalContacts.db• Lync uses Address Book Web Query

• PhotoHash• PhotoRelPath• PhotoSize

• Cached client side & server side

Lync Server Edge scenarios

• External User Access• Lync clients can transparently connect to the

Lync Server deployment over the public Internet

• PIC• Connecting with public IM providers

• Federation• Federation with other Enterprises• IM&P only, or• All modalities A/V and Application Sharing

A Few Networking Lync Facts

• Lync Server 2010 supports only IPv4• It does niet support IPv6• Can function in a network with dual IP stack

enabled• Two network adapters for each Edge Server

are required:• one for the internal-facing interface • one for the external-facing interface

• Important: The internal and external subnets must not be routable to each other.

Monitoring Server

• Monitoring Server captures both call detail record (CDR) and Monitoring Server data, which incorporates file transfer, application sharing, and remote assistance

• Instant Messaging archiving is solely covered in Archiving Server

41

Monitoring Server Overview

• Works with both Standard Edition or Enterprise Edition Pool (any supported topology)

• Requires SQL client tools on Monitoring server, if SQL database is on another server

• Microsoft Systems Center Operations Manager (SCOM) infrastructure is desirable

• SQL Server reporting Services (for detailed reports)
