Errors, delayed response, hangs
Insufficient memory or inadequate host capabilities may cause multiple errors,
delayed response, and hangs.
See “About deduplication server requirements” on page 23.
For virtual machines, Symantec recommends that you do the following:
■ Set the memory size of each virtual machine to double the physical memory
of the host.
■ Set the minimum and the maximum values of each virtual machine to the
same value (double the physical memory of the host). These memory settings
prevent the virtual memory from becoming fragmented on the disk because
it does not grow or shrink.
These recommendations may not be the best configuration for every virtual
machine. However, Symantec recommends that you try this solution first when
troubleshooting performance issues.
