Requirements

This section describes the hardware and software required and recommended for this release of Calendar Server.

• Hardware Requirements and Recommendations

• Software Requirements and Recommendations

• Important Patch Information

For Calendar Server installations that separate functionality across front-end and back-end machines, the hardware platforms and operating systems must be the same on each end.

More specifically, due to big-endian versus small-endian incompatibility, you can’t use both an x86 platform machine and a SPARC platform machine in the same Calendar Server deployment containing front-end and back-end machines.

Moreover, mixing Solaris x86 and Linux operating systems for front-end and back-end machines has not been tested and is not currently supported.

Hardware Requirements and Recommendations

• Approximately 500 MB of disk space for typical installation. For production systems, at least 1 GB.

• 128 MB of RAM. For production systems, 256 MB to 1 GB for best performance.

• RAID storage for fast access (recommended for large databases).
