Archive parameters

Archive calculation is available only if the Server and Server with display calculation types are selected — see Selecting the type of calculation. Also it is necessary that at least one stream is selected for recording — see Selecting the cameras.

The archive can be calculated in one of the following ways:

1. By time. In this case, the time period for which the archive should be stored is set, and the calculation result is the required amount of disk space.
2. By size. In this case, the amount of disk space is set, and the calculation result is the time period for which the archive can be stored on it.

Calculation by time

To calculate the disk space required for storing the video archive, select No RAID calculation.

Set the calculation parameters:

1. Archive, days — the required archive depth in days.
2. Hours per day — the average number of hours per day during which it is planned to record into the archive. 24 hours a day means permanent recording.

The disk space data is for informational purposes only. To ensure an accurate calculation, use the camera manufacturer's calculator. See the list of known calculators in the Vendor’s calculator drop-down list.

Calculation by size with RAID

To calculate the time period for which the video archive can be stored, select Calculation based on RAID RAID.

To calculate the RAID parameters required for storing the video archive, set the following parameters on the Calculation based on RAID tab:

1. RAID level. The following options are available:
   1. JBOD – simple consolidation of disks, which is not a RAID level.
   2. RAID-0 – RAID 0, an array of disks with data striping.
   3. RAID-10 – RAID 10, an array of disks with mirroring and striping.
   4. RAID-5 – RAID 5, an array of disks with block-level striping and one checksum.
   5. RAID-6 – RAID 6, an array of disks with block-level striping and two checksums.
2. Disk size in the selected units (GB or TB). It is assumed that RAID will be built on the basis of disks of the specified size. The calculation results indicate the required number of disks and other RAID parameters (see Platform calculation results for Axxon Next and Intellect Server).
