OCS 2007 R2 Hardware and OS requirements
64-bit only
As you know, R2 is moving to a 64-bit only platform to achieve greater scalability. 32-bit versions of OCS 2007 R2 will no longer be supported in production. This lines up with Exchange and other products moving this direction.
What OS can I run R2 on?
All roles of Office Communications Server 2007 R2 Enterprise Edition require one of the following operating systems:
· The 64-bit edition of Windows Server 2008 Standard, or the 64-bit edition of Windows Server 2008 Enterprise
· The 64-bit edition of Windows Server 2003 R2 Standard with Service Pack 2 (SP2), or the 64-bit edition of Windows Server 2003 R2 Enterprise with SP2
· The 64-bit edition of Windows Server 2003 Standard with SP2, or the 64-bit edition of Windows Server 2003 Enterprise with SP2
What version of SQL can I run R2 on?
The following list of supported database management systems applies to the Office Communications Server Back-End Database and to the Archiving, Monitoring, and Group Chat databases:
· Microsoft SQL Server 2008 (32-bit or 64-bit edition)
· Microsoft SQL Server 2005 with SP2 (32-bit or 64-bit edition)
What type of reference HW is required for R2?
The following tables describe the hardware requirements for an Enterprise pool that has 100,000 endpoints, includes all Office Communications Server functionality, and has eight Front End Servers.
Table 1. Enterprise Edition, Front-End Server
Hardware component |
Minimum requirement |
CPU |
· Dual processor, quad-core 2.0 gigahertz (GHz)+ · 4-way processor, dual-core 2.0 GHz+ |
Memory |
8 gigabyte (GB) |
Disk |
2x 72 GB+, 15K or 10K RPM |
Network |
2 x 1 Gbps network adapter |
If you extrapolate this information: 1 OCS FE server with all OCS functionality will ballpark around 12,500 endpoints so a typical school district/campus size, from what I have sampled, for faculty and staff two servers would be sufficient with redundancy.
The requirements in the following table apply to the Back-End Database and to Monitoring, Archiving, Group Chat, and Compliance databases.
