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 with or without RAID.

Calculation without RAID

To calculate the disk space without RAID, 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 with RAID

To calculate the disk space with RAID, do the following:

1. On the No RAID calculation tab, set the parameters of the archive depth and the average number of hours per day during which it is planned to record into the archive.
   
2. Go to the Calculation based on RAID tab and select the 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.
3. Specify the 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).
