Use of optical or tape storage is not required for OAM. In fact, as you first begin to work with objects, it can be desirable to implement a pilot application that uses only disk. If and when optical or tape storage is included in your storage management scheme, one or a combination of the hardware configurations described in Table 1 and Table 1 can be used as a standard configuration.
