HP ZCentral 4R 1U Rack Workstation

Configure Your HP ZCentral 4R 1U Rack Workstation

  • Configure


    The HP ZCentral 4R supports one Intel Xeon W-series processor. The Hyper-Threading support allows two threads to run simultaneously on each core -- Windows recognizes 36 total cores on the Z4, 18 real and 18 virtual. It also supports "Turbo Boost" which automatically boosts the processor speed based on workload - so if an application is only using one of the 18 cores it will automatically increase the speed of the core in use and turn off the unused cores.


    The HP ZCentral 4R has 4 DIMM Slots for DDR4 ECC Memory.

    Power Supply

    The HP ZCentral 4R has two power supply bays supporting two HP 675 watt power supply units (PSUs) in redundant or aggregate mode. One power supply is included by default. If you select the two power supply unit option, we will select the appropriate mode in the system BIOS based on your configuration. The optional second power supply is a rare part, so it may extend lead time. Contact us for availability if time is of the essense.

    • (1) PSU is fine for majority of configurations and if the workstation is in a accessible environment.
    • (2) PSUs are recommended if your configuration includes the NVIDIA Quadro A6000 graphics or you want redundancy (e.g. the workstation will be stored in a remote environment making it difficult to replace the PSU in case of a failure).
