When configuring a new system, the system administrator must consider several issues that have a direct impact on the number and size of disk resources required. These device allocation issues refer to commands and procedures that add disk resources to SAP ASE.

After the initial disk resources have been allocated to SAP ASE, the system administrator, database owner, and object owners should consider how to place databases and database objects on specific database devices. These object placement issues determine where database objects reside on your system and whether or not the objects share devices.

Do not consider allocating devices separately from object placement. For example, if you decide that a particular table must reside on a dedicated pair of devices, first allocate those devices to SAP ASE.
