Each time the streams are added to the list (see Selecting the cameras), or the parameters affecting the calculation are changed (bit rate, streams recording, etc.), the parameters are recalculated.
Archive size
If the Calculation without RAID option was selected (see Archive parameters), the recommended archive size will be displayed:
This will show both the size required for the video archive and the HDD marked capacity — the recommended hard drive size. In this case, it is taken into account that hard drive manufacturers use multiples of 1000 when designating capacity, while the real hard drive size is calculated in the binary system as a multiple of 1024. For example, if the HDD capacity marked by the manufacturer is 1 TB, then in fact 0,91 TB will be available for the video archive.
If the Calculation with RAID option was selected, the recommended characteristics of the RAID array will be displayed:

Custom platform
If Custom platform was selected in he Recommended platforms tab of the Result of calculation section shows the results of platform calculation for processors with the selected architecture (
...
see Selecting the CPU architecture):
The specification parameters are displayed in the following columns (2):
...
- Number of servers — the number of servers recommended for the specified number of cameras.
- Server platform — platform name and, if detection tools using the GPU/VPU are specified, links to GPU/VPU selection (
...
- see Types of detection tools). When you click on the link to the GPU/VPU selection, the documentation pages with the performance data will open.

- Server CPU load — CPU load as a percentage.
Server RAM, GB — the

recommended size and number of RAM modules for dual-channel operation, taking into account the number of processors on the platform. For example, “4 x 8GB” RAM means two 8GB RAM modules per processor for a dual-processor platform.
Info title Note RAM should be used in dual-channel mode or greater mode based on the number of processors in the platform. For example, at least 2 RAM modules must be installed for single-processor platforms, and at least 4 RAM modules for dual-processor platforms.
Using RAM at a higher frequency, or using RAM in dual-channel mode or greater mode results in CPU load decrease, and therefore in the performance increase.
- Server storage configuration: required configuration of the disk subsystem, in particular:
- Actual archive size and required HDD marked capacity for storing the archive if No RAID calculation was chosen, or actual archive size if RAID level was chosen.
- Recommended RAID configuration if RAID level was selected:
- total number of disks per server,
- disk size,
- number of RAID groups,
number of hotspare-disks.
...
Info title Example 28x 4 TB (2x RAID-6 + 1x HS) means 2 RAID-6 groups with a total of 27 4 TB disks and 1 hotspare-disk.
- Required storage recording rate: total recording rate which must be supported by the disk subsystem of the server.
- LAN (in/out): total rate of the video streams from IP cameras, to be provided by the bandwidth of the network interface of the server

Example If 100 cameras are added, and as a result of recommended platform calculation, it is recommended to use 5 servers with 50-60% server load, this means that it is required to use 5 servers and install 100/5 = 20 cameras on each server. In this case the CPU load of each server will not exceed 50-60%. |
...
For example, this screenshot shows the calculation results which are first sorted by the CPU load decrease, then by the RAM size decrease, and then by the number of servers decrease.
