- 7. DB-7 Moving On Up - Smaller Servers and Big Your direction • How many will buy new or add? • Want fast, cheap, supported • Must be safe, risk-free • How do you decide?
- 8. DB-7 Moving On Up - Smaller Servers and Big Previously supported OSes • DEC VMS • DEC Unix • MS-DOS • Novell Netware • CTOS/BTOS • Sequent Dynix/ptx • Data General DG-UX • SCO Xenix & Unix • SCO Unixware • AT&T/NCR Unix • Unisys Unix • IBM AIX • HP-UX • Sun SunOS & Solaris • MS Windows NT • RedHat & SUSE Linux • AS/400
- 9. DB-7 Moving On Up - Smaller Servers and Big Current OSes and CPUs • IBM AIX on Power • Linux – x86 – Power • HP-UX – PA-RISC – Itanium • Sun Solaris – SPARC – x86 • Windows Server – x86 • Tru64 on Alpha
- 10. DB-7 Moving On Up - Smaller Servers and Big OS and CPU trends • x86 – Intel Pentium AMD • Linux or Windows on x86 – Reduce costs – Shift most R&D costs to external – Focus on software and services – Standards rather than proprietary
- 11. DB-7 Moving On Up - Smaller Servers and Big Benefits of x86-based • Lower initial costs • Lower support costs • Increased selection – Hardware – OS – Add-ons – Vendors – Resources • Better performance • Newer features sooner • Virtualization • More timely upgrades • Budget for other options
- 12. DB-7 Moving On Up - Smaller Servers and Big Cons of x86-based • More vendors “in the mix” • Limited support for 3rd party • HW and OS support not as deep yet • Servers not always as cool looking
- 13. DB-7 Moving On Up - Smaller Servers and Big Costs of new platform • New hardware • New OS • HW, OS, and SW annual support • Porting costs (consulting or in-house) • Platform change fees
- 14. DB-7 Moving On Up - Smaller Servers and Big Solution comparisons
- 15. DB-7 Moving On Up - Smaller Servers and Big 5-year costs and savings
- 16. DB-7 Moving On Up - Smaller Servers and Big Excellent cluster config
- 17. DB-7 Moving On Up - Smaller Servers and Big Question: • Ok, so it’s cheaper… • But is it faster?

- 20. DB-7 Moving On Up - Smaller Servers and Big Today’s TPC-C results • Old days – big iron • Today - top fifty!
- 21. DB-7 Moving On Up - Smaller Servers and Big Important performance notes • Database apps need I/O and memory speed, not so much compute speed – Memory and I/O bus speed – L2 and L3 cache size – Memory size – I/O speed and spread • OpenEdge uses INT ops, not FP ops • Keep context switching to a minimum
- 22. DB-7 Moving On Up - Smaller Servers and Big Change: What’s important? • Vendor selection • Vendor support • Planning the migration
- 23. DB-7 Moving On Up - Smaller Servers and Big Vendor selection • Choose vendor you trust • Nearby parts and service • Solid Linux/Windows history and investments • Enterprise relationship
- 24. DB-7 Moving On Up - Smaller Servers and Big Vendors and support • 24x7 enterprise support is critical • Top-tier vendor – HP, IBM, Sun, Dell • Align for Windows or Linux
