Informix chunk files

Informix® chunk files can be cooked files or raw partitions. For better performance and reliability on production databases, use raw disk partitions. Only an experienced system administrator should create chunk files.
Note: Do not create chunk files on an NFS-mounted partition.

The default space suggested for the root, temp, and log dbspaces is about 1 MB per user.

The default for the ccm dbspace it is about 2 MB per user. For the default 40 users, the total is about 220 MB. For each chunk file, the limit is 4 TB.

This estimate is only a rough estimate for the initial database chunk. In general, generously allocate dbspace to allow for future growth.
