Deep Security Virtual Appliance memory usage

Applies to on-premise Deep Security software installations only

Configure the virtual appliance's memory allocation

The default configuration of Deep Security Virtual Appliance is to use 4GB of RAM. If you expect to need more than the default 4GB (which is definitely the case if you're using 10.0), you need to modify the virtual appliance's configuration yourself. There are two options:

• Modify the configuration of the virtual appliance prior to being imported to Deep Security Manager and then to the vCenter, thereby setting the default configuration for all subsequent virtual appliance service deployments in that vCenter. See Configure the virtual appliance's memory allocation prior to deployment to the vCenter
• Modify the memory allocation of the virtual Appliance on a case by case basis after it has been imported to the vCenter and deployed as a service on a ESXi. See Configure the memory allocation of an already-deployed virtual appliance.

Configure the virtual appliance's memory allocation prior to deployment to the vCenter

To change the Deep Security Virtual Appliance's default memory allocation, you must edit the allocation settings in the Appliance's OVF file before it gets imported to the vCenter.

1. Unzip the Virtual Appliance zip file you downloaded from the Trend Micro Download Center.
2. Open dsva.ovf in a text editor.
3. Edit the default memory allocation (4096 MB) to be appropriate for your environment:
   <Item>
<rasd:AllocationUnits>byte * 2^20</rasd:AllocationUnits>
<rasd:Description>Memory Size</rasd:Description>
<rasd:ElementName xmlns:rasd="http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/CIM_ResourceAllocationSettingData">4096 MB of memory</rasd:ElementName>
<rasd:InstanceID xmlns:rasd="http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/CIM_ResourceAllocationSettingData">2</rasd:InstanceID>
<rasd:Reservation>4096</rasd:Reservation>
<rasd:ResourceType>4</rasd:ResourceType>
<rasd:VirtualQuantity>4096</rasd:VirtualQuantity>
</Item>
4. Save the OVF file and return it to the zip package.
5. On Deep Security Manager, go to Administration > Updates Software > Local and import the Virtual Appliance ZIP package.

Configure the memory allocation of an already-deployed virtual appliance

2. Right-click on the virtual appliance again and select Edit Settings. The Virtual Machine Properties screen displays.
3. On the Hardware tab, select Memory and change the memory allocation to the desired value.
4. Click OK.
5. Right-click the virtual appliance again and select Power > Power On.
