IBM AS/400e server
78 AS/400e System Handbook
The AS/400e servers SB2 and SB3 perform dedicated, compute-intensive processing for
customers who choose ISV software targeted for a multi-tier environment. Up to 24 GB of
memory can be used to satisfy CPU-intensive performance requirements in multi-tier
implementations. To focus on the CPU-intensive processing objectives established for these
models, a lower number of disk arms is used. Multiple SB2 and SB3 models may be used to
push the database servers used in a multi-tier environment to their full potential.
Some of the capabilities of the current AS/400e servers are summarized in the tables on the
following pages.
