ISeries eServer Model i825. 58,216 GB of disk storage, 18 internal CD/DVD devices or 36 tape units, with equal capacities of external CD/DVD/tape devices, 135 Twinaxial Controllers can attach 5,400 twinaxial devices, 320 communications lines, and 96 LAN ports. Some of the LAN ports may displaced by up to 36 Integrated xSeries Servers or up to 18 Integrated xSeries Adapters. 9. The Model 825 supports the same Option Packages as the Models i870 and i890. 10). It comes with a minimum eight-way Symmetrical Multiprocessor and contains an additional eight CUoD processors.
Specific user(s), or it can be shared by all users. Both terminals and printers initially were attached to the system unit via twinaxial cable (or twinax), typically laid in the building’s walls or ceiling. In today’s environment, the terminals (or PCs) and printers are attached through many other media including radio communications and telephone wiring. 2 shows the packaging used for the iSeries eServer 800. This packaging is typical of the iSeries system line in that it encompasses the primary components of the computer system, including everything necessary to compose an entry system except the terminal functions identified above.
The Model i890 offers two processor options. The first processor option (#2497) contains a base 16-way processor with an additional 8 capacity on demand processors and at its maximum can realize a 24way processor system. The CPW performance rating starts at 20,000 and extends to 29,300 if the capacity on demand processors are activated. Capacity on demand is discussed in the next section of this chapter. The minimum main storage capacity for this processor is 8,192 MB and the maximum main storage capacity is 192 GB.
