戴尔 PRECISION 工作站CPU配置白皮书

2011年4月白皮书为DELL PRECISION工作站选择适当的CPU配置Mitch Markow，Core Technologies的总监在针对您的业务需求优化Dell Precision™工作站时，选择适当的处理器是一个重要注意事项。

虽然内存容量和图形卡硬盘对于特定工作负载会更重要，但处理器性能经常会决定工作完成得有多快。

通过与行业领先公司合作，戴尔为塔式、机架式和移动工作站提供多种中央处理器(CPU)配置选择。

许多Dell Precision工作站型号使用用于高性能服务器中的同样的英特尔®至强®处理器，以便提供超过台式机级别系统的更高的可靠性与性能。

选择CPU平台时的考虑事项选择CPU时，大家通常会想到的第一个问题是性能与成本。

技术考虑事项包括1个插槽(1S)还是2个插槽(2S)、核心数量、处理器频率和内存通道数量。

虽然这些确实是重要的考虑事项，但却不能脱离业务环境来回答这些问题。

选择处理器时，首先有必要确定对于您的业务而言什么是重要的，因为处理器要求取决于您尝试做的事情。

了解您的应用程序和工作负载模式对于处理器性能的依赖程度，是选择适当的处理器的重要前提条件。

台式机系统(DT)中的1个插槽与 2个插槽与1个插槽相比，2个插槽的主要益处在于核心数量以及可用于一个或多个并发应用程序的内存容量/带宽。

2S设计能够通过英特尔设计中名为QuickPath互连的一致总线来添加第二个处理器。

此总线的速度（通常以GT/秒为单位）非常重要，因为它是确定互联的带宽、处理器与相关内存之间的延迟（在NUMA[非统一内存访问]配置的系统中非常关键）的重要因素。

确保您的应用程序可以通过更多核心或更高的内存带宽和内存量来进行扩展，因为2S设计有成本和功耗方面的劣势。

核心数量、SMT和应用程序线程您需要的核心数量取决于两个重要因素：1. 您的工作负载/代码的平行程度有多高（同样，了解您的工作负载至关重要）2. 您希望同时运行多少项任务一般来讲，如果您的工作负载高度平行，可通过英特尔的超线程技术(HTT)来使用物理和逻辑核心很好地扩展性能。

工作站技术参数

工作站技术参数工作站是一种专为高性能计算和专业领域应用设计的计算机。

它通常具有比普通台式机更强大的处理能力和更高的内存容量，以满足专业用户对计算能力和数据处理的需求。

在工作站的选择和配置中，技术参数是非常重要的参考指标，它涵盖了处理器、内存、存储、图形和网络等方面的性能指标。

在本文中，我们将对工作站的技术参数进行详细介绍，并探讨如何根据不同需求选择合适的工作站配置。

1. 处理器工作站的处理器是其核心部件，影响着整机的运算速度和多任务处理能力。

常见的处理器厂商包括英特尔和AMD，它们在工作站领域推出了一系列高性能处理器。

在选择工作站时，处理器型号和核心数量是重要的参考指标。

英特尔的至强系列处理器通常采用多核心设计，能够提供强大的并行计算能力，非常适合专业领域的科学计算、工程仿真和深度学习等任务。

2. 内存工作站的内存容量直接决定了其对大规模数据处理和复杂任务的支持能力。

通常来说，8GB至16GB的内存能够满足一般专业应用的需求，但对于需要处理大型数据集或运行大规模模拟的应用，32GB以上的内存容量将更为合适。

内存带宽和延迟也是需要考虑的因素，因为它们直接影响内存与处理器之间的数据传输效率。

3. 存储工作站通常需要大容量、高速度的存储设备来满足专业用户对数据读写和处理的需求。

固态硬盘（SSD）已成为主流选择，因为它具有更高的读写速度和更低的响应时间，能够有效提升工作效率。

对于需要大容量存储的用户，传统的机械硬盘（HDD）仍然是一种经济实惠的选择。

4. 图形对于涉及图像处理、视频编辑和计算机辅助设计（CAD）等专业领域的工作站，图形性能是至关重要的。

NVIDIA和AMD是主流的专业图形处理器厂商，它们的显卡产品通常具有更多的计算单元和更大的显存容量，能够为专业用户提供更强大的图形处理能力。

5. 网络高速稳定的网络连接对于需要进行大规模数据传输和远程计算的工作站用户至关重要。

选择具有千兆以太网接口和支持最新无线标准的工作站是非常必要的。

Unless otherwise noted, each procedure included in this document assumes that the following conditions exist:•You have read the safety information that shipped with your computer.•A component can be replaced or, if purchased separately, installed by performing the removal procedure in reverse order. WARNING: Disconnect all power sources before opening the computer cover or panels. After you finish working inside thecomputer, replace all covers, panels, and screws before connecting to the power source.WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best practices information, see the Regulatory Compliance HomepageCAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team.Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.CAUTION: T o avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface at the same time as touching a connector on the back of the computer.CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by its pins.CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have connectors with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect acable, ensure that both connectors are correctly oriented and aligned.NOTE: The color of your computer and certain components may appear differently than shown in this document.CAUTION: System will shut down if side covers are removed while the system is running. The system will not power on if the side cover is removed.Before working inside your computer1 Ensure that your work surface is flat and clean to prevent the computer cover from being scratched.2 Turn off your computer.3 Disconnect all network cables from the computer (if available).CAUTION: If your computer has an RJ45 port, disconnect the network cable by first unplugging the cable from yourcomputer.4 Disconnect your computer and all attached devices from their electrical outlets.5 Open the display.6 Press and hold the power button for few seconds, to ground the system board.CAUTION: To guard against electrical shock unplug your computer from the electrical outlet before performing Step #8.CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touchingan unpainted metal surface at the same time as touching a connector on the back of the computer.1 4Before you begin7 Remove any installed ExpressCards or Smart Cards from the appropriate slots.Safety precautionsThe safety precautions chapter details the primary steps to be taken before performing any disassembly instructions.Observe the following safety precautions before you perform any installation or break/fix procedures involving disassembly or reassembly:•Turn off the system and all attached peripherals.•Disconnect the system and all attached peripherals from AC power.•Disconnect all network cables, telephone, and telecommunications lines from the system.•Use an ESD field service kit when working inside any desktop to avoid electrostatic discharge (ESD) damage.•After removing any system component, carefully place the removed component on an anti-static mat.•Wear shoes with non-conductive rubber soles to reduce the chance of getting electrocuted.Standby powerDell products with standby power must be unplugged before you open the case. Systems that incorporate standby power are essentially powered while turned off. The internal power enables the system to be remotely turned on (wake on LAN) and suspended into a sleep mode and has other advanced power management features.Unplugging, pressing and holding the power button for 15 seconds should discharge residual power in the system board. . BondingBonding is a method for connecting two or more grounding conductors to the same electrical potential. This is done through the use of a field service electrostatic discharge (ESD) kit. When connecting a bonding wire, ensure that it is connected to bare metal and never to a painted or non-metal surface. The wrist strap should be secure and in full contact with your skin, and ensure that you remove all jewelry such as watches, bracelets, or rings prior to bonding yourself and the equipment.Electrostatic discharge—ESD protectionESD is a major concern when you handle electronic components, especially sensitive components such as expansion cards, processors, memory DIMMs, and system boards. Very slight charges can damage circuits in ways that may not be obvious, such as intermittent problems or a shortened product life span. As the industry pushes for lower power requirements and increased density, ESD protection is an increasing concern.Due to the increased density of semiconductors used in recent Dell products, the sensitivity to static damage is now higher than in previous Dell products. For this reason, some previously approved methods of handling parts are no longer applicable.Two recognized types of ESD damage are catastrophic and intermittent failures.•Catastrophic – Catastrophic failures represent approximately 20 percent of ESD-related failures. The damage causes an immediate and complete loss of device functionality. An example of catastrophic failure is a memory DIMM that has received a static shock and immediately generates a "No POST/No Video" symptom with a beep code emitted for missing or nonfunctional memory.•Intermittent – Intermittent failures represent approximately 80 percent of ESD-related failures. The high rate of intermittent failures means that most of the time when damage occurs, it is not immediately recognizable. The DIMM receives a static shock, but the tracing is merely weakened and does not immediately produce outward symptoms related to the damage. The weakened trace may take weeks or months to melt, and in the meantime may cause degradation of memory integrity, intermittent memory errors, etc.The more difficult type of damage to recognize and troubleshoot is the intermittent (also called latent or "walking wounded") failure. Perform the following steps to prevent ESD damage:Before you begin5•Use a wired ESD wrist strap that is properly grounded. The use of wireless anti-static straps is no longer allowed; they do not provide adequate protection. T ouching the chassis before handling parts does not ensure adequate ESD protection on parts with increased sensitivity to ESD damage.•Handle all static-sensitive components in a static-safe area. If possible, use anti-static floor pads and workbench pads.•When unpacking a static-sensitive component from its shipping carton, do not remove the component from the anti-static packing material until you are ready to install the component. Before unwrapping the anti-static packaging, ensure that you discharge static electricity from your body.•Before transporting a static-sensitive component, place it in an anti-static container or packaging.ESD field service kitThe unmonitored Field Service kit is the most commonly used service kit. Each Field Service kit includes three main components: anti-static mat, wrist strap, and bonding wire.Components of an ESD field service kitThe components of an ESD field service kit are:•Anti-Static Mat – The anti-static mat is dissipative and parts can be placed on it during service procedures. When using an anti-static mat, your wrist strap should be snug and the bonding wire should be connected to the mat and to any bare metal on the system being worked on. Once deployed properly, service parts can be removed from the ESD bag and placed directly on the mat. ESD-sensitive items are safe in your hand, on the ESD mat, in the system, or inside a bag.•Wrist Strap and Bonding Wire – The wrist strap and bonding wire can be either directly connected between your wrist and bare metal on the hardware if the ESD mat is not required, or connected to the anti-static mat to protect hardware that is temporarily placed on the mat. The physical connection of the wrist strap and bonding wire between your skin, the ESD mat, and the hardware is known as bonding. Use only Field Service kits with a wrist strap, mat, and bonding wire. Never use wireless wrist straps. Always be aware that the internal wires of a wrist strap are prone to damage from normal wear and tear, and must be checked regularly with a wrist strap tester in order to avoid accidental ESD hardware damage. It is recommended to test the wrist strap and bonding wire at least once per week.•ESD Wrist Strap Tester – The wires inside of an ESD strap are prone to damage over time. When using an unmonitored kit, it is a best practice to regularly test the strap prior to each service call, and at a minimum, test once per week. A wrist strap tester is the best method for doing this test. If you do not have your own wrist strap tester, check with your regional office to find out if they have one.T o perform the test, plug the wrist-strap's bonding-wire into the tester while it is strapped to your wrist and push the button to test. A green LED is lit if the test is successful; a red LED is lit and an alarm sounds if the test fails.•Insulator Elements – It is critical to keep ESD sensitive devices, such as plastic heat sink casings, away from internal parts that are insulators and often highly charged.•Working Environment – Before deploying the ESD Field Service kit, assess the situation at the customer location. For example, deploying the kit for a server environment is different than for a desktop or portable environment. Servers are typically installed in a rack within a data center; desktops or portables are typically placed on office desks or cubicles. Always look for a large open flat work area that is free of clutter and large enough to deploy the ESD kit with additional space to accommodate the type of system that is being repaired. The workspace should also be free of insulators that can cause an ESD event. On the work area, insulators such as Styrofoam and other plastics should always be moved at least 12 inches or 30 centimeters away from sensitive parts before physically handling any hardware components•ESD Packaging – All ESD-sensitive devices must be shipped and received in static-safe packaging. Metal, static-shielded bags are preferred. However, you should always return the damaged part using the same ESD bag and packaging that the new part arrived in.The ESD bag should be folded over and taped shut and all the same foam packing material should be used in the original box that the new part arrived in. ESD-sensitive devices should be removed from packaging only at an ESD-protected work surface, and parts should never be placed on top of the ESD bag because only the inside of the bag is shielded. Always place parts in your hand, on the ESD mat, in the system, or inside an anti-static bag.•Transporting Sensitive Components – When transporting ESD sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place these parts in anti-static bags for safe transport.ESD protection summaryIt is recommended that all field service technicians use the traditional wired ESD grounding wrist strap and protective anti-static mat at all times when servicing Dell products. In addition, it is critical that technicians keep sensitive parts separate from all insulator parts while performing service and that they use anti-static bags for transporting sensitive components.6Before you beginTransporting sensitive componentsWhen transporting ESD sensitive components such as replacement parts or parts to be returned to Dell, it is critical to place these parts in anti-static bags for safe transport.Lifting equipmentAdhere to the following guidelines when lifting heavy weight equipment:CAUTION: Do not lift greater than 50 pounds. Always obtain additional resources or use a mechanical lifting device.1Get a firm balanced footing. Keep your feet apart for a stable base, and point your toes out.2Tighten stomach muscles. Abdominal muscles support your spine when you lift, offsetting the force of the load.3Lift with your legs, not your back.4Keep the load close. The closer it is to your spine, the less force it exerts on your back.5Keep your back upright, whether lifting or setting down the load. Do not add the weight of your body to the load.
