Configuring HP SIM for Optimal Performance in Large Environments
Disks—The
number
of
drives
needed
to
support
the
input/output
requirements
or
the
amount
of storage
space
(in
MB)
required
to
hold
the
data
Memory—The amount of memory needed to support a given workload
Network—The number and type of network interface cards (NICs) needed to support workload demands
Ideally, you set the CPU as the limiting resource because processing power provides the most scalable solution.
However, this setup requires an established balance among the remaining resources (disk, memory, and
network). After this balance is achieved, adding more memory or additional processors does not necessarily
improve system performance. Increasing CPU speed is the best way to improve performance. However, the
limiting resource might be application-related, not hardware-related.
Job cleanup for a large number of managed systems
When
running
Systems Insight Manager
in
an
environment
that
contains
a
large
number
of
managed
systems,
the

output
might
exceed
several
thousand

This
