Software Recommendations

In addition to the support requirements, there are some general recommendations that can help improve the performance of the Lync virtual servers. The first is to use host servers only for virtualization. Do not run additional applications or services on servers that host virtual machines. These applications or services have processing, memory, and network requirements that might have an adverse effect on virtual machines.

The second recommendation is to properly configure any anti-virus application because anti-virus applications that run on a host server can have a serious performance effect on virtual machines. Any locations with a virtual disk file should be excluded from virus scans to avoid performance issues. Anti-virus applications are not aware of how to scan a virtual disk file, so they treat it as any other file. Because virtual disk files are quite large, this can cause performance issues while the anti-virus application attempts to scan the file.
