System Management Performance Monitor Compaq offers Windows NT Performance Monitor Add-On Enhancement Tools to aid in the easy installation and removal of Objects and Object Counters for the Compaq EISA and PCI Buses, Power Supply and NetFlex-3 Controllers. The System Management Performance Monitor, specifically, adds several System Management Objects to the Windows NT Performance Monitor. These counters include items concerning the EISA Bus, PCI Bus, and Power Supply. These counters require Compaq Support Software Version 1.21A or later for Microsoft Windows NT and Compaq Insight Manager 3.30 or later. These tools are available on the Compaq Resource Paq for Microsoft Windows NT. To obtain a copy of the Compaq Resource Paq, go to the Compaq Microsoft Frontline Partnership page located on the web at: //www.compaq.com/solutions/frontline Once the System Management Performance Monitor utility is installed, view the counter data collected by the drivers through the Performance Monitor Utility included with Microsoft Windows NT. Balancing Bus Use Compaq Insight Manager supports bus use measurements on each PCI bus and on the EISA bus. The bus use measurement tools provide a good way to check the I/O configuration to ensure that peripherals are properly balanced across the two PCI buses. An indication of unbalanced bus use implies that the system might need to be reconfigured to optimize performance. Refer to Compaq Insight Manager documentation for more information about using these tools. PCI BUS LOADING WITH REDUNDANT CONTROLLERS Compaq has offered many innovative solutions to reducing network downtime on Compaq server networks. Some of these solutions include: • Online Storage Controller Recovery Option • Compaq Advanced Network Control Utility Online Storage Controller Recovery Option The Compaq Online Storage Controller Recovery Option provides redundancy at the mass storage controller level by merging two SMART-2 controllers into a controller pair. In such a pair, one controller is active, and the other remains in standby mode. Should a problem occur with the active controller, the device driver switches traffic to the standby controller without loss of data or interruption of service. A complete description of this fault tolerance feature can be found in the white paper called Implementing Online Storage Controller Recovery in Windows NT, July 1997 - Doc ID 066A/0797. Compaq Advanced Network Control Utility The Compaq Advanced Network Control Utility is a network-monitoring tool that allows a user to install, uninstall, configure and monitor NetFlex-3 controllers. This utility also displays PCI bus number assignments, bus type and slot numbers associated with each device. 10

System Management Performance Monitor
Compaq offers Windows NT Performance Monitor Add-On Enhancement Tools to aid in the easy
installation and removal of Objects and Object Counters for the Compaq EISA and PCI Buses,
Power Supply and NetFlex-3 Controllers.
The System Management Performance Monitor, specifically, adds several System Management
Objects to the Windows NT Performance Monitor.
These counters include items concerning the
EISA Bus, PCI Bus, and Power Supply.
These counters require Compaq Support Software
Version 1.21A or later for Microsoft Windows NT and Compaq Insight Manager 3.30 or later.
These tools are available on the Compaq Resource Paq for Microsoft Windows NT.
To obtain a
copy of the Compaq Resource Paq, go to the Compaq Microsoft Frontline Partnership page
located on the web at:
//www.compaq.com/solutions/frontline
Once the System Management Performance Monitor utility is installed, view the counter data
collected by the drivers through the Performance Monitor Utility included with Microsoft
Windows NT.
Balancing Bus Use
Compaq Insight Manager supports bus use measurements on each PCI bus and on the EISA bus.
The bus use measurement tools provide a good way to check the I/O configuration to ensure that
peripherals are properly balanced across the two PCI buses.
An indication of unbalanced bus use
implies that the system might need to be reconfigured to optimize performance.
Refer to Compaq
Insight Manager documentation for more information about using these tools.

Online Storage Controller Recovery Option
The Compaq Online Storage Controller Recovery Option provides redundancy at the mass storage
controller level by merging two SMART-2 controllers into a controller pair.
In such a pair, one
controller is
active
, and the other remains in
standby
mode.
Should a problem occur with the
active controller, the device driver switches traffic to the standby controller without loss of data or
interruption of service.
A complete description of this fault tolerance feature can be found in the
white paper called
Implementing Online Storage Controller Recovery in Windows NT, July 1997
– Doc ID 066A/0797.
Compaq Advanced Network Control Utility
The Compaq Advanced Network Control Utility is a network-monitoring tool that allows a user to
install, uninstall, configure and monitor NetFlex-3 controllers.
This utility also displays PCI bus
number assignments, bus type and slot numbers associated with each device.
NOTE:
Compaq Insight
Manager also monitors PCI bus
utilization on SCO UNIX and
Novell NetWare servers.
