You can compress the partitions in primary storage as soon as they are closed to save disk space. This requires additional I/O to compress and store on the primary partition, which means that the supported EPS rate will be significantly lower. Also, searches on these partitions will be slower. Therefore, this option is only suitable for lower EPS rates and if you want to get the most out of primary storage space.
To compress the storage index on the primary partition:
Log in to the system as the root user.
Open the /etc/opt/novell/sentinel/config/configuration.properties file.
Set the localstorage.indexes.compress property to true.
Restart the Sentinel server.
