Tool-free design
HP has always been a leader in tool-free product design and with the HP Z640, the serviceability could not be any easier!
The following components can be easily accessed or upgraded without tools: side access panel, hard drives, optical
drives, memory, expansion cards, power supply, system board, and the 2nd processor module. The hard drives are also
direct-connect and can be swapped in and out without dealing with cables. Users will find the translucent hard drive
carriers very helpful when determining which bays are populated with a drive.
Security
Due to the tool-free ease of use, HP understands system and component security may be a concern; therefore, several
security features have been incorporated. The side access panel key lock and a security slot are included standard. A
system intrusion sensor and a remote/centrally controlled solenoid lock are optional accessories.
Quiet and reliable
Acoustic noise is very important to HP and our customers because a noisy environment can increase user fatigue
and reduces productivity. HP continues its leadership in this area with the design of the Z640. With its extra power
and capability, one might expect the HP Z640 to be louder than the already very quiet HP Z620. However, with some
innovative engineering using very efficient heatsink design, strategically placed fans, and active fan control, the HP Z640
is even quieter. As with all our workstations, the hard drives are mechanically isolated to reduce vibration and noise.
The system is arranged so that sensitive components receive fresh cool air. With internal fans distributed throughout
the system, airflow is targeted at the high power-density components. HP’s advanced algorithms control fan speeds
in real time based on system configuration, environment, and key component temperatures to provide users with an
exceptionally quiet system and uncompromising reliability and performance.
While low acoustics and thermal reliability are priorities, it is also important that the system can withstand difficult
physical conditions. The HP Z640 is built to withstand high shock and vibration environments. Rigorous climatic and
dynamic testing helps to ensure that HP Workstations are highly reliable in demanding conditions.
Designed with the environment in mind
HP is committed to environmental sustainability and energy efficiency. To reduce energy consumption, HP Workstations
offer ENERGY STAR® qualified configurations and the HP Z640 features a 90% efficient power supply. The HP Workstation
design team has taken a proactive approach (beyond industry regulations) to recyclability and selecting materials that
reduce the risk to the environment. HP Z640 configurations are available with low-halogen materials.
