  3. Inleiding ING Group Fusie (1999 – 2001)

  4. Situering Systems Engineering → IBM Mainframe Engineering: • IBM Mainframe z/890 A04 → 350 MIPS • Terminal (telnet) • Aankoop: 1.125.000 EUR • Jaarlijks: (1.408.886 EUR) • Onderhoud: 25.000 EUR • IBM Software: 1.089.228 EUR • Non-IBM Software: 294.658 EUR

  5. Waarom mainframes ? • 350 vs. ± 11500(P4 3.6) MIPS? • MIPS ≠ MIPS • I/O operaties ++ • CICS, DB2, … HW support • Multi-user • Reliability
