By default, DSVA is assigned 2GB of memory. Here is the recommended memory for the DSVA machine, depending on the number of virtual machines per ESXi Host.

• Increase the memory to 2GB for a DSVA protecting 1 to 50 virtual machines.
• Increase the memory to 4GB for a DSVA protecting 51 to 100 virtual machines.
• Increase the memory to 8GB for a DSVA protecting 101 to 150 virtual machines.
• Increase the memory to 8GB for a DSVA protecting 151 to 200 virtual machines.
• Increase the memory to 12GB for a DSVA protecting 201 to 250 virtual machines.

For information on DSVA memory, refer to the following KB article: Sizing recommendations for Deep Security Virtual Appliance (DSVA).

DSVA also needs additional memory if you are using the Scan Cache function introduced in Deep Security 9.0. To know how much memory the Scan Cache settings require, refer to this KB article: Scan Cache settings in DSVA.

To increase the memory:

1. On vCenter Console, go to the DSVA Console tab.
2. Power off the DSVA.
3. Press Alt + F2 keys and logon using dsva/dsva.
   1. Type in the command "sudo shutdown –h now".
   2. Go to Summary > Edit Settings > Hardware tab.
4. Allocate 8 GB of memory to the virtual appliance.
5. Power on the DSVA.
