CommentsCategory Tested items Is Fujitsu better

than HP?

1 Power consumption

• Power consumption• Power supply efficiency ×

• HP has an advantage over Fujitsu in terms of server power consumption.• Both servers have equivalent levels of power conversion efficiency

(Just a difference of certification organizations).

2 Cooling• Proper ventilation in servers• Internal server temperatures• Fan control

◎

• The HP server has a number of small ventilation holes, but the actual temperature measurements show the Fujitsu server can operate at much lower temperature.• Both servers provide fan control features.

3 Design • Server weight• Noise levels △ • The lighter-weight Fujitsu server is more space optimized.

• HP has an advantage over Fujitsu in terms of noise levels.

4 Features• Hot swap components• Supported LAN ports• Supported PCI slots• Data security

○

• The PRIMERGY RX300 offers hot-swap fans.• The HP server can contain more LAN ports than Fujitsu PRIMERGY.

But LAN ports on the Fujitsu server have LEDs that can indicate link status and the LAN speed.• The Fujitsu and HP servers hold the same number of PCI slots.• HP and Fujitsu are closely competitive in being able to provide

advanced security features (TPM).

5 Serviceability

• Failure notification LEDs• The ability to perform

maintenance tasks while the server remains in a rack enclosure.

◎

• The Fujitsu server ensures that notification LEDs are lit even when the server is unplugged. This is not offered by HP.• The dedicated fan cover on the Fujitsu server can be removed/

reinstalled while server remains in rack. On the other hand, the HP server must be uninstalled from a rack enclosure for every maintenance task.

It seems Fujitsu is a clear winner on server cooling, features and ease of serviceability. On the other hand, in the area of hardware design, HP has a slight advantage over Fujitsu.◎ :Particularly superior ○ : Superior △ : Equivalent × : Inferior

Due to the insufficient number of ventilation holes, the HP server fails to deliver an adequate volume of fresh cold air required to cool the internal components. There’s no ventilation holes around the disk area, and it will likely increase the risk of disk failure due to thermal problems.

Limited air intakes.

Insufficient ventilation holes at front and rear of the HP server. The small holes cannot deliver sufficient t volume of fresh cold air.

Rear

Small vent holes are scattered at the rear of the server, but they are not aligned with air flow.

Sufficient ventilation holes are reserved at the front and rear of the server to ensure fresh cold air is routed to the internal components.

A multi-layer arrangement of heat-generating components will create hot spots within the server.

Not many components sit on the motherboard to mitigate congestion. The component layout is optimized in align with airflows to cool all components efficiently and effectively.

Not many components sit on the motherboard to avoid a congested layout. The Fujitsu server uses a straight-line cooling method to streamline cold air movements within the server chassis.

Thermal design of the HP server is not optimized (Fewer ventilation holes than Fujitsu PRIMERGY, non-straight airflow paths). That makes it difficult to deliver air volume required to cool all internal components, and produces hot spots within the server chassis.

Fujitsu PRIMERGY is much less susceptible to thermal issues, allowing longer component life.

Server temperature measurements revealed that the HP server operates at a 10˚C higher temperature (Max.) than the Fujitsu server. During the test, both servers with their default settings were identically loaded. A scientific study (Arrhenius Theory of Reaction Rate*) says lifetime of temperature-dependent components (i.e. Capacitors) is halved for every 10 degree Celsius increase in temperature.

When comparing two identically rack-mounted solutions (15 Fujitsu/HP servers in a 19-inch rack),the Fujitsu rack system was 44kg lighter than the HP system.Fujitsu servers seem to be more suitable for customers with floor space constraints.

This configuration cannot be installed in an office space with floor loading capacity of 500kg/m².

The Fujitsu servers are lighter than HP’s, allowing higher-

density server deployments.

This configuration can be installed in an office space with floor loading capacity of 500kg/m².

* These calculations assume the rack enclosure weighs 150kg net, and installs in 1m².

* Total weights shown above include rack rails and cable arms.

* Typical floor load limits in normal office buildings: 300 to 500kg per square meter.

Need a driver to release the latch. Small handles make

it difficult to pull out the server tray.

To replace the system board assembly of the HP server, it must be removed completely from a rack enclosure. Service technicians need to prepare adequate flat space when conducting tasks, and re-install the removed assembly into the rack after the maintenance.
