This is dynamic allocation of the cache resource.3. Integrated memory controller vs. non-integratedThe presence of the System Request Interface, Cross bar, and the high-speed serial interface (HyperTransport) are all logical results of having an integrated memory controllerIt is difficult to say which implementation/system architecture is better. They simply are a different means to the end. What matters is how they perform on a given workload.幻灯片 36幻灯片 37幻灯片 38幻灯片 39Intel Turbo Boost Technology increases performance of both multi-threaded and single threaded workloads. Intel Turbo Boost Technology is activated when the Operating System (OS) requests the highest processor performance state (P0).The maximum frequency of Intel Turbo Boost Technology is dependent on the number of active cores. The amount of time the processor spends in the Intel Turbo Boost Technology state depends on the workload and operating environment, providing the performance you need, when and where you need it.Any of the following can set the upper limit of Intel Turbo Boost Technology on a given workload:Number of active cores Estimated current consumption Estimated power consumption Processor temperature When the processor is operating below these limits and the users workload demands additional performance, the processor frequency will dynamically increase by 133 MHz on short and regular intervals until the upper limit is met or the maximum possible upside for the number of active cores is reached. Conversely, when any of the limits are reached or exceeded, the processor frequency will automatically decrease by 133 MHz until the processor is again operating within its limits.Example for 4C Turbo operation: A database query, which doesnt use any of the processors floating point silicon, so it can take advantage of that thermal headroom and increase the frequency of all 4 cores.幻灯片 40幻灯片 41Key points:Highly-differentiated stack: Not just frequency and to a lesser extent FSB, but five major features (describe each)Similar to before, the 2S SKUs are broken down into 3 segments, and weve created two major performance selves to encourage sell-up at strategic points in the stack. Huge performance gains between the shelf. Instead of 3-5% bin-to-bin, now youre getting multiple bins of performance. Even with de-featuring the value SKUs, were still over 25% gen-to-gen performance gains from Xeon 5400.What this also does is create more separation between the bottom and top SKUs, which really opens up the top-to-bottom performance gains (over 80% vs NHM as opposed to 30% for HTN). Refer back to the Xeon 5400 ROI study and project forward to even better TCO as you buy up the stack with Xeon 5500 series. The buy high,. better ROI story!幻灯片 42幻灯片 43幻灯片 44幻灯片 45幻灯片 46幻灯片 47幻灯片 48幻灯片 49幻灯片 50幻灯片 51幻灯片 52幻灯片 53幻灯片 54幻灯片 55幻灯片 56Single Device Data Correction 幻灯片 57幻灯片 58幻灯片 59幻灯片 60幻灯片 61幻灯片 62幻灯片 63幻灯片 64幻灯片 65幻灯片 66幻灯片 67幻灯片 68幻灯片 69幻灯片 70幻灯片 71幻灯片 72幻灯片 731、热插拔管理：支持单板热插拔，热插拔管理符合PICMG3.0规范；2、状态监视：提供对服务器单板、机框等的状态监视功能；3、告警与策略：提供告警查询、告警上报、告警门限/迟滞配置、告警策略配置；4、日志 ：提供日志的自动记录以及查询功能；5、设备控制 提供单板上/下电、复位、power cycle、诊断中断等控制， 支持CMOS清除等操作，提供风扇框自动、手工调速等控制功能；6、电子锁E-KEYING7、功率管理 提供机框功率、单板功率管理，支持机框功率配置与查询功能；8、资产管理 提供对机框、模块的FRU信息查询与设置
