ECG078/0698 TECHNOLOGY BRIEF (cont.) ... The ProLiant 7000 Server provides investment protection by retaining essential system components and the chassis serial number. When customers upgrade previously purchased ProLiant 7000 Servers to a Pentium II Xeon four- or eight-processor (4- or 8-way) configuration, they will leverage the following components: • Chassis • Rack mounting kit • Serial number • Agency labels • Power supplies • Memory DIMMs (4-way upgrade only) • Hard disk drives and backplanes • Integrated Management Display • CD-ROM, tape, and floppy drives (4-way upgrade only) • All PCI adapter boards • Keyboard • Monitor The upgrade will reduce the total cost of ownership over the lifetime of the server, including administrative and hardware costs. Because many enterprise operating systems, application software installations, and warranties are linked to the hardware serial numbers, continuation of the chassis serial number reduces administration costs. The chassis design and replaceable components of the ProLiant 7000 allow unprecedented flexibility. Early engineering analysis shows that the Pentium II Xeon processor and the 100MHz bus it supports create more power and thermal load than the current Pentium Pro-based systems. In planning for the Pentium II Xeon processor and 4-way requirements, Compaq engineered the ProLiant 7000 power supplies and chassis with "headroom" to accommodate this additional load. Power Supplies The ProLiant 7000 design allows the intelligent power supplies to share the power load. With three power supplies installed, there is enough power to run up to eight processors and still maintain redundancy. In a redundant configuration, the supplies deliver up to 1500 W; while in a nonredundant configuration, they deliver up to 2250 W of power. This far exceeds typical power configurations for SMP servers, which range in maximum power capabilities from 700 to 840 W. Fan Cooling Capacity The fans have also been designed with extra "headroom" to allow for future growth paths with additional processors. As mentioned previously, the fans have both high- and low-speed settings. Performance testing of the ProLiant 7000 shows that even in 35ºC ambient air with all four processors loaded, the fans maintain adequate cooling inside the box while running at low speed. The excellent fan performance and the extra room inside the chassis provide ample airflow and cooling to support a future upgrade to eight Slot 2 processors. 21

The ProLiant 7000 Server provides investment protection by retaining essential system
components and the chassis serial number.
When customers upgrade previously purchased
ProLiant 7000 Servers to a Pentium II Xeon four- or eight-processor (4- or 8-way) configuration,
they will leverage the following components:
•
Chassis
•
Rack mounting kit
•
Serial number
•
Agency labels
•
Power supplies
•
Memory DIMMs (4-way upgrade only)
•
Hard disk drives and backplanes
•
Integrated Management Display
•
CD-ROM, tape, and floppy drives (4-way upgrade only)
•
All PCI adapter boards
•
Keyboard
•
Monitor
The upgrade will reduce the total cost of ownership over the lifetime of the server, including
administrative and hardware costs.
Because many enterprise operating systems, application
software installations, and warranties are linked to the hardware serial numbers, continuation of
the chassis serial number reduces administration costs.
The chassis design and replaceable components of the ProLiant 7000 allow unprecedented
flexibility.
Early engineering analysis shows that the Pentium II Xeon processor and the 100-
MHz bus it supports create more power and thermal load than the current Pentium Pro-based
systems.
In planning for the Pentium II Xeon processor and 4-way requirements, Compaq
engineered the ProLiant 7000 power supplies and chassis with “headroom” to accommodate this
additional load.
Power Supplies
The ProLiant 7000 design allows the intelligent power supplies to share the power load.
With
three power supplies installed, there is enough power to run up to eight processors and still
maintain redundancy.
In a redundant configuration, the supplies deliver up to 1500 W; while in a
nonredundant configuration, they deliver up to 2250 W of power.
This far exceeds typical power
configurations for SMP servers, which range in maximum power capabilities from 700 to 840 W.
Fan Cooling Capacity
The fans have also been designed with extra “headroom” to allow for future growth paths with
additional processors.
As mentioned previously, the fans have both high- and low-speed settings.
Performance testing of the ProLiant 7000 shows that even in 35ºC ambient air with all four
processors loaded, the fans maintain adequate cooling inside the box while running at low speed.
The excellent fan performance and the extra room inside the chassis provide ample airflow and
cooling to support a future upgrade to eight Slot 2 processors.
