Windows Server 2008 R2
Windows Server 2012
Windows Server 2012 R2

Minimum of 100 MB RAM per concurrent scan
For example, if you planned on your agent conducting scans on 4 volumes or shares concurrently, you would need a minimum of 400 MB of RAM.
NOTE:Performance depends not only the number of concurrent scans, but also the size of the directory structure for each volume or share. Adding more RAM than the minimum requirement can obviously increase performance.
Minimum of 10 GB free disk space
Depending on the size and number of concurrent scans, this amount might need to be significantly increased.
