HP Z1 Workstation - Frequently Asked Questions
What is special about the HP Z1 Workstation?
The New HP Z1 is a unique addition to the Z Workstation family, both as a product and a user's target. This system brings revolutionary changes to and features to the All-in-One market with its sleek, tool -less design and support of ECC memory, professional graphics, and Intel Xeon branded processor technologies.
How will the HP Z1 Workstation be sold and distributed?
The HP Z1 Workstation will be sold on the Web, via distributor/VARs (indirect/direct channels), and HP sales force.
Does the end-user have to recompile the applications to see the performance advantages of the new Intel Xeon processors?
No, testing and Intel data indicate that technical applications show immediate performance in creases due to the new processor and memory architecture.
How to add the second processor? Is a system board swap required?
CPU upgrades are field and end-user installable without system board swaps using the HP Z Workstations CPU upgrade kit. The second processor must be the same speed and stepping as the first.
What are the benefits of multi-core processors?
Intel multi-core processors provide greater processing resources. Multi-core processors are ideal for usage models requiring multi-tasking (running many applications or simulations at once); working on spreadsheets while listening to music with virus checkers and system backups running (power office); or using applications that can split a task across processors (multi-threaded), like animation/rendering in Digital Content Creation.
What do these terms (Multi-core, Dual-socket, Dual-core, Quad-core, Six-core, Eight-core) mean?
What is Intel Turbo Boost 2.0 technology?
Intel Turbo Boost Technology 2.0 is a way to automatically run the processor core faster than the marked frequency if the part is operating under power, temperature, and current specifications limits of the Thermal Design Power (TDP). This results in increased performance of both single and multi-threaded applications.
How much faster will the processor run with Intel Turbo Boost 2.0 technology?
The maximum frequency of Intel Turbo Boost 2.0 is dependent on the number of active cores. The amount of time the processor spends in the Intel Turbo Boost 2.0 state depends on the workload and operating environment. Any of the following can set the upper limit of Intel Turbo Boost 2.0 on a given workload:
When the processor is operating below these limits and the user's workload demands additional performance, the processor frequency will dynamically increase until the upper limit of frequency is reached. Intel Turbo Boost 2.0 has multiple algorithms operating in parallel to manage current, power, and temperature to maximize performance and energy efficiency.
NOTE: Intel Turbo Boost 2.0 allows the processor to operate at a power level that is higher than its rated upper power limit (TDP) for short durations to maximize performance.
Why did HP choose to implement Liquid Cooling?
HP places a large priority on satisfying user's requirements. Achieving the lowest acoustics levels is a priority for HP Workstations. Implementing Liquid Cooling provides extremely efficient heat removal from the processors, allowing the remaining system fans to run at greatly reduced RPMs, which reduces the overall acoustic output levels. Configurations where the processor fans are not the dominant noise source will not significantly benefit from Liquid Cooling. Examples of possible configurations where processor fans are not the dominant noise source are memory configurations where all memory slots are filled or configurations with 15K SAS drives.
What is the procedure to order Liquid Cooling?
Liquid Cooling is a Configure-to-Order option. This provides with a choice between Air Cooling and Liquid Cooling.
What is special about the new chassis?
The HP Z Workstations’ sleek new industrial design, brushed aluminium side panels, tool-less access chassis, integrated handles, and visually cable-less engineering, creates new standards for ease of service, lowered acoustics, and energy efficiency.
Graphically, what is special with the HP Z Workstations?
HP Workstations support one of the widest ranges of professional 2D up to Ultra High -End 3D graphics from AMD and NVIDIA, for the most visually-demanding applications. Depending on the workstation, user can drive up to eight displays and take advantage of PCI Express Gen3 expansion slots.
Does the PCI Express channel deliver any advantage beyond accommodating two graphics cards?
Yes, the PCI Express channels form highly efficient, high-performance general-purpose I/O busses that may be used for any device that is able to take advantage of the PCI Express interface.
What is meant by PCI Express (PCIe)?
PCIe is the latest generation of PCI architecture. PCI Express is a radically new implementation of the PCI computer bus that uses existing PCI programming concepts and communications standards, but is based on a much faster serial communications system. PCI Express x16 slots provides up to eight times the aggregate bandwidth of a PCI-X 133-MHz 64-bit slot (8 GB/s bidirectional).
What are the advantages of PCI Express for graphics? What are the differences?
PCI Express is the next generation interface not only for graphics cards, but also for I/O cards. PCI Express is a scalable interface, and depending on the chipset the system can have multiple PCI Express connections with various bandwidths. For graphics cards, the defined standard is by sixteen (or x16). This implementation of PCI Express provides twice the unidirectional bandwidth and four times the peak bandwidth as AGP 8X.
What graphics cards are available?
What size of graphics memory should be used?
Graphics performance is dependent upon many factors, including the amount of video memory. Higher performing cards also include bigger and faster GPUs, more memory bandwidth, and tend to have more features like dual-link connectors and support for stereo. The higher performance graphics cards will also have more memory (and a higher price). A dual display configuration at 1920 x 1200 pixels will allocate about 70MB for the frame buffer. The remaining graphics memory will be used to store textures, display lists (graphics data sent by applications), and other data specific to graphics. If the application would benefit from more storage space for these items, then user should purchase a graphics card with more memory.
Do the HP Z Workstations support Serial ATA (SATA) and serial attached SCSI (SAS) RAID?
Yes, the chipset used on the HP Z Workstations has an integrated 6-channel SATA controller with RAID support for RAID 0 (striped), RAID 1 (mirrored), RAID 5 (parity), and RAID 10 (striped and mirrored). User can choose to have a high performance RAID 0 array of hard drives where data is striped across multiple hard drives (this RAID method greatly improves data access times and system performance). User can choose to have a highly reliable RAID 1 array of hard drives, where data is duplicated to multiple hard drives at once (this RAID method creates a backup copy of all data in real time). User can choose to implement a RAID 5 array, which protects against data loss and provides faster throughput. Data is distributed across at least two hard disks, with error correction information stored on an additional disk. Finally, user can choose to implement a RAID 10 array, which offers the advantages of RAID 0 and RAID 1 by utilizing four hard disks.
What Operating Systems are available on the new HP Z Workstations?
A variety of Operating Systems (OSs) are available, including the following. Please note that the exact Operating Systems (OSs) carried by each workstation vary by product.
Is dual Operating System (OS) preload an option?
Dual Operating System (OS) preload will not be offered due to restrictions of licensing agreements.
Will the HP Z Workstations support Linux?
Yes, Red Hat Enterprise Linux Desktop/Workstation is available as a drop-in-the-box with 1-year paper license. Red Hat Enterprise Linux (RHEL) 4 is not supported on new HP Work stations models.
Does the HP Installer Kit for Linux actually contain the Red Hat Box Operating System (OS)?
No, user must obtain the Red Hat software bits from Red Hat. The HP Installer Kit for Linux is a CD set to be used in conjunction with a Red hat Enterprise Linux install. Red Hat requires that users purchase Red Hat Enterprise Linux Desktop license from either HP or Red Hat directly.
What manageability features are available on HP Personal Workstations?
All current HP Workstations (HP Z1, HP Z210 CMT, HP Z210 SFF, HP Z420, HP Z620, and HP Z820) support DASH 1.1 manageability via the onboard Intel LAN. Additionally, these workstations feature Intel vPro TM technology when configured with the appropriate processor. These technologies, along with a manageability software solution or console, provide the ability to remotely manage these workstations. Remote management of HP Workstations platforms is recommended by HP on LANDesk Management Suite, but these platforms have also been tested on major software solutions including Microsoft System Center Configuration Manager and Altiris Client Management Suite.
How can user remotely access the full performance of HP Workstation?
HP Remote Graphics Software (RGS) is the remote desktop solution for serious workstation users and their most demanding applications. Best of all, it comes with every new HP Z Workstation. This advanced tool allows users to access and share the desktop of a remote workstation over a standard network. All applications run natively on the remote workstation and take full advantage of the compute and graphics resources of the sending system. HP RGS also allows professionals to collaborate in real time with colleagues across the hall or across the continent using graphic intensive applications.
