Platform Support and System Requirements
CE Dual Processor Support and CPU Requirement
Release 4.0 requires two processors in each CE, which are necessary for the server to boot. If
your server is configured with only one CPU in either of the CEs, the server will not boot. Also,
use of the /onecpu switch in the boot.ini file has no effect; even if you set this switch, your
server will boot using both CPUs in the CE.
In addition, all processors in the CEs must be the same model (for example, Pentium®III or
Pentium III XeonTM) and speed. As of the initial Release 4.0, Pentium III or Pentium III Xeon
are the only supported CPU types.

CE Configuration Requirements
Release 4.0 CEs must be configured identically, and must contain identical chipset versions to
avoid loss of CE synchronization when various system management tools are used. In
particular, the Add/Remove Hardware Wizard, Device Manager, and System Information tools
may cause the CEs to lose synchronization unless all of the following conditions are met:
Table 2 CE Configuration Requirements
Element Requirement
CE processors Must have the same model, stepping, and cache configurations.
CE BIOS revision Must match.
CE BIOS settings All configurable BIOS options must be identical (for example, serial and
parallel port settings, etc.).
CE add-in cards Card slot placements must match.
CE RAM The same DIMM slots must be occupied by DIMMS of the identical
manufacturer, type, and size.

4 Endurance Release Notes for Release 4.0 Service Pack 1
CE Motherboard BIOS Settings
Use the BIOS Setup Utility to verify that all onboard device settings between the two CEs are
identical. We strongly recommend that parallel, serial, SCSI, and network devices be disabled
on the CE.
Make sure that the following devices are enabled:
• Video adapter
• Keyboard
•Mouse
• 3.5-inch Floppy Disk — this can be disabled when it is not needed for maintenance
operations, such as flashing the BIOS.
In addition, the CE MICs must use the same IRQ and addresses, or the CEs will not be permitted
to synchronize.
On some systems, disabling of embedded devices is not allowed. Ensure that the embedded
devices that are still enabled on the CE motherboard use the same IRQ on both CEs. Not doing
so may result in a prompt from Windows requesting to reboot because a new device has been
installed.
In Windows 2000, if a device’s resource requirement changes between reboots, Windows will
recognize the device as a new device and install supporting software for the device. The
installation of supporting software may result in a prompt from Windows to reboot the system
because a new device has been installed. You may experience this behavior when the IRQ of
enabled embedded devices is not the same on both CEs.
This occurs because the responsibility for booting Windows may be on one CE during a boot
cycle, during which it presents the embedded devices with its assigned resources. But, on the
next boot cycle, the other CE may be responsible for booting Windows. In that case, it presents
the embedded devices with a difference set of assigned resources, causing Windows to
recognize the device as a new device.
Platform Support
The Endurance server supports only Pentium III or Pentium III Xeon processors on the CEs and
IOPs. However, use of the Pentium III serial number (PSN) is not supported in applications on
the CEs. For more updated information about additional platforms that are qualified to run
Endurance Release 4.0, refer to the HP Customer Support Web site.

Endurance Release Notes for Release 4.0 Service Pack 1 5
Motherboard Requirement
The motherboards on all computers (CEs and IOPs) in the server must be capable of supporting
two or more processors.
Memory Requirement
An Endurance server requires a minimum of 256 MB of memory in the CEs and IOPs. In
addition, the server can support up to 4 gigabytes of memory in the CEs. There is no limit to
supported memory in the IOPs.
Marathon Interface Card (MIC) Requirement
An Endurance server requires the Marathon Interface Card (MIC) version 4.2 or 4.3. For best
performance in the IOPs, we recommend configuring the MIC with its own interrupt if possible,
rather than sharing an interrupt. Also, you should install the MIC in a primary PCI bus slot, and
not behind a secondary bridge chip.
If you plan to configure your server for extended long distance SplitSite, with tuples installed
up to 10 kilometers apart, you must use version 4.3 of the MIC. Refer to the section Marathon
Interface Card (MIC) 4.3 Available for information about this MIC and how to recognize
whether you have this version of the MIC.
Partition Format Requirement
Endurance Release 4.0 requires the use of NTFS partitions for all disks used in the server. Also,
the CE boot partition size is limited to 4000 megabytes. Refer to General Limitations for more
information about extending this partition size limit.
Operating System Requirements
In addition to the installation requirements listed in the HP Netserver AA Solution Installation
Guide, the operating system versions that are supported for Endurance Release 4.0 Service Pack 1
are described in Table 3.

Endurance Enhancements in Release 4.0 Service Pack 1
Endurance Release 4.0 Service Pack 1 includes the following enhancements to the Endurance
software.
Support for Windows 2000 Service Pack 2
Release 4.0 Service Pack 1 introduces support for Windows 2000 Service Pack 2. If you choose
to install Windows 2000 Service Pack 2, you must be running Endurance Release 4.0.1-SP
software. Do not attempt to install Windows 2000 Service Pack 2 on any Endurance release
earlier than Release 4.0.1-SP.
If you choose to upgrade your Endurance server to use Windows 2000 Service Pack 2, you must
reboot the server after each installation, as follows:

Support for Long Distance SplitSite®Distances Up to 10
Kilometers
As of Endurance Release 4.0 Service Pack 1, you can install the tuples up to 10 kilometers apart.
In order to configure your server with this SplitSite configuration, you must install Version 4.3
of the Marathon Interface Card (MIC), described in the next section.
Marathon Interface Card (MIC) 4.3 Available
MIC version 4.3 accommodates increased long distance SplitSite installations with tuple
separations of up to 10 kilometers. You can identify this version of the MIC by examining the
cable connector ports on the MIC. This version has blue plastic casing around the external part
of the Remote port, instead of the silver color that was used in the V4.2 MIC. The blue plastic
casing is visible from the rear of the server with the MIC installed.
Singlemode Fiber Support
MIC version 4.3 can use either singlemode fiber or multimode fiber for the Remote port. For
distances greater than 500 meters, you must use singlemode fiber. For distances of 500 meters
or less, you can use either singlemode fiber or multimode fiber. Table 4 and Table 5 describe
the cable specifications.

different fiber optic wave lengths than those in
the V4.2 MIC, requiring the installation of plugs
into the individual ports for loopback testing.
2 Carefully remove the protective covers
from the loopback plugs.
3 Insert one plug into the REMOTE port
and the second plug into the LOCAL
port, gently pushing them in until you
hear a slight click.
4 Perform the BIOS loopback tests. Refer to Using the MIC BIOS Setup Utility
starting on page 7-3 in the Endurance
Administrator’s Guide for information about
performing BIOS loopback tests.
5 After loopback tests are complete,
remove the loopback plugs, as follows:
• Gently compress the arched fitting
located behind the rectangular
plastic box on the plug.
• After you hear a slight click, remove
the plug.
After removing the plugs, carefully put the
protective covers back on the plugs.

Cabling for Staging Purposes in Long Distance SplitSite Installations
When staging the Endurance server for test purposes only, cable the MICs and IOP Link (IL)
as follows:
• MIC cables — Use the 2 local fiber optic cables and 2 remote fiber optic cables shipped in
your kit to connect the server components. The two different length cables shipped in
your kit are interchangeable when distance is not an issue during staging.
• IOP Link (IL) cables — Use the 2 multimode (SC to SC) cables to connect the two IL
Ethernet adapters.

Known Limitations
The following sections describe special Release 4.0 considerations, as well as the general and
third-party known limitations that have an impact on the Release 4.0 Endurance server.
Release 4.0 Considerations
CE Driver Signing Policy Considerations
The MtcPrep executable, part of the CE Unattended Installation, sets the Driver Signing Policy
for the CE operating system to Ignore in the Registry, and gives the user no warning notification
about this change.
Once you log in to the CE operating system for the first time and set up an Administrator
password, you can change file signature verification so that you are warned before unsigned
drivers are installed. To do so, follow these steps:
IL Cable 2 singlemode patch
cords (that you obtain)
with SC connectors on
each end
IL singlemode
gigabit network
adapters on
IOP1 to IOP2 via
the patch panel
1. Attach one end of the patch
cord to the IL Ethernet
adapter port on IOP1 and the
other end of the cord to the
patch panel.
2. Attach one end of the patch
cord to the IL Ethernet
adapter port on IOP2 and the
other end of the cord to the
patch panel.
Be sure to connect the adapters
that support the IL and not the
adapters that connect your server
to the network.

Dynamic Disk Considerations
Release 4.0 supports the use of dynamic disks, as described below. To use dynamic disks with
the Release 4.0 Endurance software, consider the following:
• Consider using a basic disk for the CE boot disk. Some Windows 2000 resource kit items
do not support dynamic disks.
• Always use the Windows 2000 Disk Manager on the CE to create or update dynamic disks
and to write the disk signature. Do not create or update dynamic disks, write the disk
signature, or perform any dynamic disk operations on the IOPs. Managing volume
creation or extension from any environment other than the CE operating system will
produce unpredictable results and is not supported.
• You can perform the following disk management activities:
- Convert the CE boot disk and data disks from Basic to Dynamic. To do so,
perform the conversion on the CE operating system, not from an IOP in Offline
Endurance I/O Processor Mode.
- Create or extend volumes that span multiple redirected CE disks for volumes
created on the CE operating system.
- Configure CE data disks for simple volumes, spanned volumes, mirrored
volumes, striped volumes, or RAID volumes for disks created on the CE
operating system.
2IntheDevice Manager section, select Driver Signing.
3IntheFile signature verification section, click Warn,
and then OK.
Resetting this parameter to Warn
causes a message to be displayed
before any unsigned files are
installed.

Performance Monitor Considerations
The Endurance Performance Monitor is not installed automatically as part of the standard
Endurance installation. If you elect to install it, you may see the following events in the
Application Event Log when Endurance performance counters are enabled:
The data buffer created for the "MtcPerf" service in the
"%SystemDrive%\Program Files\Marathon Endurance\MtcPerf.dll"
library is not aligned on an 8-byte boundary. This may cause problems
for applications that are trying to read the performance data buffer.
Contact the manufacturer of this library or service to have this
problem corrected or to get a newer version of this library.
The Open Procedure for service "Nbf" in DLL
"%SystemDrive%\WINNT\system32\perfctrs.dll" failed. Performance
data for this service will not be available. Status code returned is
data DWORD 0.
Additional related events may also appear in your event log.
This is a known problem that occurs with Windows 2000 Service Pack 1. The problem also
occurs if other applications are used that install performance monitor plug-ins of their own, such
as SQL Server 7 or Exchange 5.5. The cause is currently unknown. We continue to investigate
the problem. For more information, refer to the Microsoft Knowledge Base article “Event ID
2033 Warning Message Logged When Loading Performance Monitor” at http://
support.microsoft.com/support/kb/articles/Q267/8/31.ASP.
If the above symptoms occur on your system, and you had installed the Endurance Performance
Monitor plug-in, consider uninstalling it. To do so:
Step Action Notes
1 Open a Command Prompt window.
2 Change to the Marathon Endurance Program files directory
> cd/d "%programfiles%\Marathon Endurance".
Alternatively, in Windows
Explorer, you could browse to
this directory and double-click
on MTCUPERF.EXE.
3 Type MTCUPERF.

General Limitations
• CE boot partitions larger than 4000 megabytes are supported on some controllers. If your
environment requires a CE boot partition larger than 4000 megabytes, consider the
following:
- Endurance Release 4.0 software does not provide extended INT13 BIOS support.
Because of this, the size of the CE boot partition is restricted to sectors that can be
accessed via INT13 calls that use Cylinder/Head/Sector (CHS) mapping. In CHS
mapping, the maximum number of heads is 255; the maximum number of cylinders is
1023; and the maximum number of sectors per track is 63. Some controllers have
lower limits than these, with the maximum sectors per track often being limited to 32,
which creates a partition limit of 4000 megabytes.
- The IOP SCSI/RAID controller to which the CE boot disk is attached is the
component that determines the actual limit. If that controller supports 63 sectors per
track by default, or can be configured to support 63 sectors per track for the CE boot
disk, then you can have a partition size of 7.9 gigabytes. To use this partition size,
configure both IOPs to support 63 sectors per track. For some controllers, you can
choose between 2 gigabyte and 8 gigabyte support. Select 8 gigabyte support.
• Network connections may be lost temporarily during CE resynchronization. To minimize
the impact of such a loss, you can disable automatic synchronization. Then use a script to
schedule CE synchronization at a convenient time.
• After all steps in the CE Windows and Endurance Installation are complete, CE
motherboard devices that were detected during unattended setup will appear in Device
Manager with yellow warning circles. These devices have been disabled by the Endurance
software. You can ignore the yellow warning circles.
• The Endurance IOP installation procedure installs the IOP MIC driver programmatically
rather than using the Add/Remove Hardware Wizard. A consequence of this is that the
IOP MIC device appears in Device Manager under Other devices as a Mass Storage
Controller with a yellow warning circle. You can ignore the yellow warning circle;
there is nothing wrong with the MIC device.
• The use of redirected floppy drives and redirected serial ports is not supported on Release
4.0.
• Release 4.0 supports only PS/2 interfaces for the redirected keyboard and mouse.
Redirected USB input devices are not supported.
• CEs in Release 4.0 must be configured identically, including CPU cache and steppings.
Refer to the section CE Configuration Requirements in these Release Notes for more
