Virtual Scanner Capacity Based On Hardware

In the following section you get understanding about How to know hardware requirement and scanner capacity?

Comparison chart

Utilize hardware at best possible level to leverage the Qualys scanner effectively.

Capacity RAM  No. of CPU core
60 1 GB 1
66 2 GB 1
66 4 GB 1
135 4 GB 2
135 8192 MB 2
273 8192 MB 4
411 8384 MB 6

CPU core specification: As Intel Core i7-4850HQ CPU @ 2.3 GHz

Virtualization platform: VMware Fusion

Basically 1 core counts as  "60".

  • 4 cores can do around "240" + a bit more because of the memory

  • 6 cores can do around "360" + a bit more because of the memory

  • 8 cores can do around "480" + a bit more because of the memory


Data is produced under best-conditioned environment and the result might vary according to your setup.

Resize the Hard Disk

Stop the instance, find the Hard Disk/Storage option in your Virtual Machine settings and increase the size of the disk (reducing the size is not supported). Save your settings and start up your scanner. Your scanner instance should come up with the new disk size.

Instance Size

The maximum supported size for a scanner instance was 16 CPUs and 16 GB RAM. From the qVSA-3.10 release, these limitations have been removed.
