Calculation of storage capacity
An important parameter of CoaxProv is the calculation of storage needs. Ref.769330 has a 4GB on internal eMMC,
but in the case that available space is exhausted the CoaxProv emits an alarm and deletes the oldest records.
This capability is controlled by the configuration parameters of the
Provision Database> Provision Configuration>
Database Configuration
As seen in the image, device reports are stored for 24 hours. The consumption of each report in the database is
1KByte/report. So if we have a system with 600 devices, sending a report every minute, the storage capacity per
day will be:
1KB/report x 600 reports/minute x 60 min/hour x 24 hhour = 864000 KB = 864MB/day
Changing the time that reports are stored on system (Keep Records For Last) from 24h to 1 week, the need for
storage will be:
864MB/day x 7days =6,04GB
The value required for storage is 6GB, exceeding the internal capacity of 4GB.
To increase the storage capacity insert an external microSD into the expansion slot of the device. microSD Card
must have only one partition
with
Ext4
filesystem. Reboot the system using the Administration Web on port
15712:
System>Boot And Shutdown>Reboot System
.
On boot system will detect that there is an microSD and will install internal database on EMMC on SD, without risk
of information will be lost.
