Storage hierarchies

E. I. Cohen, G. M. King, J. T. Brady
1989 IBM Systems Journal  
Thus the design of a cache control unit must offer availability and reliability characteristics very similar to those of the DASD.  ...  DASD control unit cache performance. The buffering of data in a high-speed, lookaside cache depends on a characteristic of data called locality of reference.  ...

1975 Journal of Systems Management  
There are two secondary characteristics in the data base concept: Residence on direct access devices (DASD) and on-line accessing via remote terminals.  ...  These processes embody the use of a common set of data definitions required by programs using the data base, and the definitions are maintained by a central task group either formed in a DP organization  ... 

Processor, I/O path, and DASD configuration capacity

J. B. Major
1981 IBM Systems Journal  
Extensive use of fixed-head storage devices also reduces DASD and channel service times.  ...  Characteristic /O times for current products are obtained from experience. When specific measurement information is not avail- able, one may use the information given in Table 5.  ...

The cube-connected-cycles: A versatile network for parallel computation

Franco P. Preparata, Jean Vuillemin
1979 20th Annual Symposium on Foundations of Computer Science (sfcs 1979)  
Model development from the collection of raw data to the estimation of the expected reward is described. Both normal and error behavior of the system are characterized.  ...  A reward function, based on the service rate and the error rate in each state, is then defined in order to estimate the performability of the system and to depict the cost of different types of errors.  ...  Carter for valuable discussions during the initial phase of this work. We also thank L. T. Young and P. Duba for their careful proofreading of the draft of this manuscript.  ...
