administrator to configure a specific server (while it is offline) from a remote
system, prior to starting the operating system.
See 5.2, “System Partition Manager” on page 150 for more information.
Active PCI Manager — Active PCI Manager helps optimize I/O performance
by matching the PCI-X bus and card characteristics and offering guidance on
the best slots in which to install PCI and PCI-X adapters.
See 5.1, “Active PCI Manager” on page 130 for details.
Capacity Manager — Capacity Manager monitors critical server resources
such as processor utilization, disk capacity, memory usage and network
traffic. Using advanced artificial intelligence, it identifies bottlenecks for an
individual system, a group of systems, or a cluster, and recommends
upgrades to prevent diminished performance or downtime. Capacity Manager
can even identify latent bottlenecks and make recommendations for
preventive action. For example, Capacity Manager can predict hard disk drive
and memory shortages that might cause problems.
Because Capacity Manager features can help predict problems before they
occur, the administrator can perform proactive planning and schedule service
and upgrades before potential problems degrade performance.
Capacity Manager will be updated to support partitioning in the next release
of IBM Director, planned for the second half of 2002.
Cluster Manager — Cluster Manager allows an administrator to easily
identify, configure, and manage clustered servers using one graphical tool.
Administrators can be alerted via pager or e-mail about cluster events in
hardware, the operating system, and Microsoft Cluster Service (MSCS).
Alternatively, Cluster Manager can trigger recovery programs or others
automatically.
Management Processor Assistant — The Management Processor
Assistant (MPA) task, previously named the Advanced System Management
task, lets the administrator monitor critical subsystems as well as restart and
troubleshoot servers, even if a server has suffered a fatal error or is powered
off. This utility works in concert with the IBM family of systems management
processors and adapters described previously. IBM Director 3.1 added
management support for the RXE-100 Remote I/O unit.
Rack Manager — Rack Manager offers a drag-and-drop interface for easily
configuring and monitoring rack components using a realistic visual
representation of the rack and its components. It also provides detailed health
status information for the rack and its elements. IBM Director 3.1 added the
ability to drag-and-drop objects between racks.
RAID Manager — RAID Manager lets an administrator configure, monitor,
and manage ServeRAID subsystems without taking the server offline. IBM
Director 3.1 includes field replaceable unit (FRU) number reporting in alerts
