Two Mainframe Models

Two mainframe models:-

                Mainframes are available with a variety of processing capabilities to suit the requirements of most business organizations. In the case of IBM, for example, each mainframe model provides for sub-capacity processors from granular processing requirements up to the full range of high-end computing.

Let’s look at two entries from IBM (Figure 1-3):

• System z Business Class (BC)
• System z Enterprise Class (EC)

                       The System z Business Class (BC) could be said to be intended for small to mid-range enterprise computing, and delivers an entry point with granular scalability and a wide range of capacity settings to grow with the workload. The BC provides for a maximum of up to 10 configurable PU-s.

                      The BC shares many of the characteristics and processing traits of its larger sibling, the Enterprise Class (EC). This model provides granular scalability and capacity settings on a much larger scale and is intended to satisfy high-end processing requirements. As a result, the EC has a larger frame to house the extensive capacity that supports greater processing requirements. The EC offers up to 64 configurable CP-s.
