8.1 Required hard disk space for data storage.
The CM files stored on the hard disk can vary from 1 5MB up to in some cases more than
50MB. Therefore it is important from time to time to check whethe r enough free space is
present on the hard disk. ChemoMetec recommends a minimum of 10GBs free space on
the hard disk.
It is recommended to make a periodic archiving of CM files to external storage. Those
archived CM files can then be removed from the har d disk of the PC.
The periodic archiving can be made on either the creation date of the CM file, or when the
free disk space is below a certain amount, or when the disk space used for CM files
exceeds a certain amount. Contact the local IT Administrator in order to get information
about procedures for external data storing.
A good example of the archiving procedure could be based upon:

CM files older than 3 months are archived

CM files uses more than 50GBs of disk space, archive the oldest CM files until le ss
than 20GB is used

When less than 10 GBs free space, archive the oldest CM files until less than 20GB
is used.
Refer to the NucleoView™ NC-250™ Software User’s Guide 5 for additional information.
