Deep Security Virtual Appliance memory allocation
The default configuration of the Deep Security Virtual Appliance is to use 4 GB of RAM. If you expect to need more than the default 4 GB, you will need to modify the appliance's configuration. There are two options:
- Modify the configuration of the appliance prior to being imported to Deep Security Manager and then to the vCenter, thereby setting the default configuration for all subsequent appliance service deployments in that vCenter.
- Modify the memory allocation of the appliance on a case-by-case basis after it has been imported to the vCenter and deployed as a service on a ESXi.
For information about the amount of RAM to allocate for appliances, see Deep Security Virtual Appliance sizing.
Configure the appliance's memory allocation prior to deployment to the vCenter
To change the appliance's default memory allocation, you must edit the allocation settings in the appliance's OVF file before it gets imported to the vCenter.
- Unzip the appliance zip file you downloaded from the Trend Micro Download Center.
- Open dsva.ovf in a text editor.
- Edit the default memory allocation (4096 MB) to be appropriate for your environment. See, Deep Security Virtual Appliance sizing for more information.

- Save the OVF file and return it to the zip package.
- On Deep Security Manager, go to Administration > Updates Software > Local and import the appliance ZIP package.
