Memory Configuration

To view or change the current memory configuration, select Memory in the left-hand pane of the Settings window.

The example below shows the Charon-SSP/4U configuration screen:

The following table lists each of the fields available in the memory configuration window and describes their use.

Virtual machine memory configuration fields

Field

Description

Memory for this virtual machine

Set the amount of RAM allocated to the virtual SPARC machine. Memory must be allocated in certain increments. The allocation rules for each virtual machine family are as follows:

SUN-4M: 64MB, 128MB, 256MB and 512MB
SUN-4U: 1 to 128GB in 1GB increments
SUN-4V: 1 to 1024GB in 1GB increments (not a drop-down list but manual entry).
Actual limits are different depending on guest OS: Solaris 10: 1TB, Solaris 11: 512 GB.
The GUI allows higher values, but this is for future use.

Memory allocator

This option specifies the memory allocation method used for the virtual machine. The default is malloc. It is appropriate for most cases. Please contact Stromasys if your environment has special memory requirements. Options:

Malloc: all virtual machine RAM is allocated from system heap.
Mmap: all virtual machine RAM is allocated from file backed virtual memory by memory mapping.
