Performance is in Internal Throughput Rate (ITR) ratio based on measure- ments and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user’s job stream, the I/O confi guration, the storage confi guration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here.

Photographs shown are engineering prototypes. Changes may be incorpo- rated in production models.

This equipment is subject to all applicable FCC rules and will comply with them upon delivery.

Information concerning non-IBM products was obtained from the suppli- ers of those products. Questions concerning those products should be directed to those suppliers.

All customer examples described are presented as illustrations of how these customers have used IBM products and the results they may have achieved. Actual environmental costs and performance characteristics may vary by customer.
