A/V Edge Server 500 concurrent audio/video sessions

Note A/V experience may be degraded if sessions approach themaximum limit. We recommend that you deploy a separate A/V EdgeServer for the optimal A/V experience

12. Audio/Video Capacity Planning ModelThis section summarizes the model used as a basic of our hardware recommendations for audioand video. Our capacity planning model is based on the following assumptions:

40 | P a g e


41/45

In meeting with more than five participants, five users have active bidirectional(send/receive) media streams at a time. All other users are muted (receive only).

All media streams are encrypted using SRTP.

Audio Talking profile is based on the following:

80 percent of the time 1 user talks

7 percent of the time 2 users talk

13 percent of the time nobody talks

All video streams assumed are 244 Kbps with 15 fps.

When running on the recommended hardware, the following table summarizes the Audio/VideoConferencing Server capacity in different scenarios based on this audio/video model.

13. Server Platform Requirements

13.1Hardware for Standard Edition and Enterprise Edition ServersHardware requirements vary according to server role, configuration, and storage requirements.This topic summarizes the requirements for the following server configurations. Server roles not

listed in this section are addressed in subsequent sections for the following server configurations.

13.2Standard Edition Server configured as one of the following: Front End Server, Web Conferencing Server, and A/V Conferencing Server

Director

Web Conferencing Edge Server or Access Edge Server

13.3Enterprise Edition Server configured as one of the following: Consolidated Enterprise Edition Server (Front-End Server, Web Conferencing Server, A/VConferencing Server, and IIS collocated on server)

Front End Server in expanded configuration (conferencing servers and IIS installed onseparate computers)

Web Conferencing Server in the expanded configuration

IIS Server in the expanded configuration

Archiving and CDR Server

CPU Dual processor, dual core 2.6 GHz +

Disk 2 x 18 GB

For collocated Standard Edition Server, add:

2 x 36 GB, 15K RPM, RAID 0, for database log files

2 x 36 GB, 15K RPM, RAID 0, for database data

Cache 1 MB L2 per core

Memory 2 GB (4 GB for Standard Edition Server or ConsolidatedEnterprise Edition Server)

Network GBit NIC

13.4Hardware for A/V Conferencing Servers and A/V Edge ServersThe following hardware requirements are required for A/V Conferencing Servers in an expanded

pool configuration and all standalone A/V Edge Servers.CPU Dual processor, dual core 3.0 GHz

Disk 2 18 GB


Memory 4 GB

Network GBit NIC (for A/V Conferencing Server)

2 GBit NIC (for A/V Edge Server)

13.5Hardware for Archiving and CDR DatabaseFor the Archiving and CDR database server, the recommended hardware is as follows if onlyCDRs are enabled:

CPU Dual processor, dual-core 2.6 GHz +

42 | P a g e


43/45

Disk Drive 1 (2 18 GB) for OS and Page FileDrive 2 (4 x 36GB, 15K RPM, RAID 0+1) for database log file

Drive3 (4 x 36GB, 15K RPM, RAID 0+1) for database file


Memory 4 GB (CDR only)

Network GBit NIC

Additional memory and disk capacity is required if CDRs and IM archiving are enabled:



Drive3 (6 x 72GB, 15K RPM, RAID 0+1) for database file


Memory 16 GB (CDR and Archiving)

Network GBit NIC

13.6Hardware for Small to Medium Size Back-End Database for anEnterprise Pool

For an Enterprise Edition Server deployed as a small to medium size (up to 50,000 users) Back-End Database server, the recommended hardware is as follows:


Disk Drive 1 (2 18 GB) for OS and Page FileDrive 2 (36GB, 15K RPM) for database log file

Drive 3 (36GB, 15K RPM) for database log file

Drive 4 (8 x 36GB, 15K RPM, RAID 0+1) for database files


Memory 8 GB

Network GBit NIC

13.7Hardware for Large Back-End Database for an Enterprise Pool

For an Enterprise Edition Server deployed as a large size (up to 125,000 users) Back-EndDatabase, the recommended hardware is as follows:

CPU Quad processor, dual-core 2.6 GHz +


Drive 3 (4 x 36GB, 15K RPM, RAID 0+1) for database log file

Drive 4 (8 x 36GB, 15K RPM, RAID 0+1) for database files


Memory 16 GB

Network GBit NIC

The disk recommendations for the backend database server are based upon the following I/Opattern for a 125,000 user deployment. Alternative disk configurations may provide equivalentscalability and reliability. Consult your storage hardware vendor for more information.

43 | P a g e

NoteThe disk recommendations for the Archiving Server are based upon a disk write rate of

140 writes/sec for the database file, 910 writes/sec for the log file, or the equivalent of1430 IMs/sec. Disk reads are effectively zero through in-memory caching provided by theSQL server. Alternative disk configurations may be possible to sustain the same I/O rateand reliability. Consult your storage solution vendor for more information.
