History• Began at IBM Rochester
– New Branding of AS/400 (since 2000)– Introduced in 1988– Market focused follow on to System/38
• System/38 design focused, not successful

Design• POWER5
– First POWER5 implementation– 64-bit since 1995
• Single-level storage– Access by name, not address– High speed switching between
active and idle processes– Object persistence– 264 addresses
• TIMI– Technology Independent Machine
Interface– Switch hardware
• No recompile• Full use of hardware
• POWER Hypervisor

Resilient• Object Oriented Operating System
– Objects can only have certain operations performed on them– One object cannot become another
• File can’t become a program• Program can’t be created without authenticating user
– Virus free• http://skyviewpartners.com/java-skyviewp/pdf/Virus-Got-You-Down.pdf
• Security– Written into microcode– Can’t be circumvented
• Superior backup and recovery

Integrated
•DBA
– allocating disk space for database objects
– partitioning and balancing disk drives for optimal performance
– re-balancing system index structures
– checking the integrity of the database
– updating database statistics for query optimizer

Integrated• Only one choice of “database”
– DB2 UDB for iSeries– Part of i5/OS
• Things you don’t do:– Start– Stop– Balance– Database security– Optimize
• in general, of course “it depends”

Testimonials• Software distribution company
– Good AS/400 customer• 23 AS/400s globally• Kept current on technology
– Decided to migrate to NT• June of 1999 unplugged 23 AS/400s • Replaced with 1,200 NT servers
– One year later, after failing to complete migration, returned to AS/400’s– Reportedly still running on them today
• That company is Microsoft. Link above should work on most builds of Windows XP Professional. If not, click here.
