This topic describes the minimum requirements for servers that run Office Communications Server 2007 R2.

Important

Office Communications Server 2007 R2 requires 64-bit hardware. The 32-bit hardware used for prior versions of this product cannot be reused for Office Communications Server 2007 R2.

Hardware requirements vary according to server role, topology (that is, Standard Edition, Enterprise Edition in a consolidated configuration, or Enterprise Edition in an expanded configuration), and storage requirements, and are determined by the specific deployment scenario.

The following tables describe the hardware requirements for an Enterprise pool that has 200,000 endpoints and eight Front End Servers, for instant messaging (IM) and presence only.

Note

Monitoring Servers, Archiving Servers, and Group Chat Servers that do not host their associated databases have the same hardware requirements as a Front End Server.

Table 1. Enterprise Edition, Front End Server

Hardware component Minimum requirement

CPU

  • Dual processor, quad-core 2.0 GHz+

  • 4-way processor, dual-core 2.0 GHz+

Memory

8 GB

Disk

Local storage with at least 30 GB free disk space

Network

2-port 1 Gbps network adapter (recommended)

The requirements in the following table apply to the Back-End Database and to Monitoring, Archiving, Group Chat, and Compliance databases.

Note

Monitoring Servers, Archiving Servers, and Group Chat Servers that host their associated databases have the same hardware requirements as the database.

Table 2. Enterprise Edition, Back-End Database

Hardware component Minimum requirement

CPU

  • 4-way processor, quad-core 2.0 GHz+

  • 8-way processor, dual-core 2.0 GHz+

Memory

32 GB

Disk

  • 2x RAID 1 (mirrored), 10K RPM or 15K RPM for system files

  • 2x RAID 1 (mirrored) 15K RPM for database log files (rtcdyn.ldf and rtc.ldf should be installed on two separate, dedicated drives)

  • 8x RAID 10 (striped and mirrored) 15K RPM disks for database data files

Network

2-port 1 Gbps network adapter (recommended)

Note

Clustered back-end servers are supported.
