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.

All statements regarding IBM’s future direction and intent are subject to 
change or withdrawal without notice, and represent goals and objectives only.
