10.2 Designing HiRDB file system areas

When a HiRDB system is constructed, areas for HiRDB-specific files (HiRDB files) must be created. This section discusses the design considerations for creating HiRDB file system areas.

Separate HiRDB file system areas should be created for the types of items listed below, so that contention between input/output operations on files with different purposes or access characteristics can be avoided. If regular files are used, write performance can be improved by specifying the purpose explicitly, and an appropriate device can be allocated according to the purpose. Separate file system areas should be created for:
