Calculate size requirements for RDB

[emaddocks]

Hi,

Does anyone know how many bytes are used for storing individual Digital and Analog event and alarm data in a historical RDB?

Ultimately we would like to do a rough size calculation by knowing how many IO points we have configured as archived and how often we expect the values to change.

For example:

• If a Digital Point is 100 bytes per record

• We have 10,000 Digital Points archived

• We expect a state change once every minute on average

This would require = 100 * 10,000 * 1,440 = 1.44 GB / day

Cheers
Eric
