  • Last updated on

Barracuda recommends the following sizing for initial deployment of your virtual appliance, or upgrading existing installations.

Cores, RAM, and Hard Disk Space for the Barracuda Application Security Control Center Vx

ModelMinimum CoresRAM - Recommended MinimumHard Disk - Recommended Minimum
V400 Vx24 GB50 GB

Note:

(1)  To increase the performance of this model, you should plan on adding 1 GB of RAM for each additional core. Also plan to add additional hard disk space. To purchase licenses for additional cores, contact your Barracuda sales representative.

Allocating Cores

In your hypervisor, specify the number of cores to be used by the Barracuda Application Security Control Center Vx. Each Barracuda Application Security Control Center Vx model can use only the number of cores specified in the table above. For example, if you assign 4 cores to the Barracuda Application Security Control Center V400 Vx (which supports only 2 cores), the hypervisor disables the 2 extra cores that cannot be used.

To add cores to your appliance:

  1. Shut down the Barracuda Application Security Control Center Vx in your hypervisor.
  2. In the virtual machine CPU settings, add cores.

Your hypervisor license and version might limit the number of cores that you can specify for your appliance. In some cases, you must add cores in multiples of two.

Allocating Hard Disk Space

Barracuda requires a minimum of 50 GB of hard disk space to run your Barracuda Application Security Control Center Vx. From your hypervisor, you can specify the size of the hard disk or add a hard disk.

To specify the allocated hard disk space or add a hard disk to your appliance:

  1. Shut down the Barracuda Application Security Control Center Vx in your hypervisor.
  2. Take a snapshot of the virtual machine.
  3. In the virtual machine settings, specify the new size for the hard disk or add a new hard disk.
  4. Restart the virtual machine. As the appliance is booting up, view the console for Barracuda Application Security Control Center Vx. When the blue Barracuda console screen appears and asks if you want to use the additional hard disk space, enter Yes.

If you do not respond to the prompt in 30 seconds, the answer defaults to No. Resizing can take several minutes, depending on the amount of hard disk space specified.
