Methodology 2 is much more granular than Methodology 1 because it accounts for the various workloads. This methodology only applies to the on-demand scan due to the sizing and because expected performance can vary based on different job performance impact levels.
The assumption for this methodology is as follows:
Typical antivirus scan roundtrip time (RTT) for each CAVA connection = 40ms
The known condition for this methodology is as follows:
Define the total number of the requests per second which will trigger the on demand scan as R
Maximum connections per CAVA servers=20
The algorithm is as follows:
In the following example, the scan profile is standard, the SMB close requests are 1,000 operations per second, and the SMB rename requests are 200 operations per second. The number of CAVA servers required is as follows:
Minimum number of CAVA servers required=(1000+200)/500=1200/500=2.4≈3
