Disk-layout guidelines

The following goals are typical for efficient disk layout:

Limiting disk-head movement
Reducing disk contention
Balancing the load
Maximizing availability

You must make some trade-offs among these goals when you design your disk layout. For example, separating the system catalog tables, the logical log, and the physical log can help reduce contention for these resources. However, this action can also increase the chances that you must perform a system restore. For detailed disk-layout guidelines, see the HCL OneDB™ Performance Guide.
