class=MsoNormal style="TEXT-INDENT: 17.85pt; mso-char-indent-count: 1.7">大家都知道，2005年双核处理器架构带来CPU革命性的变化。简而言之，双核处理器即是基于单个半导体的一个处理器上拥有两个一样功能的处理器核心，处理器的性能及功能大大增强。因为处理器实际性能是处理器在每个时钟周期内所能处理指令数的总量，因此增加一个内核，处理器每个时钟周期内可执行的单元数将增加一倍。本次DIY服务器主要作为网页、电子邮件及数据库应用，需要大的网络流量和强劲的运算能力，选择双核心CPU是必然的。<o:p></o:p><

class=MsoNormal style="TEXT-INDENT: 17.85pt; mso-char-indent-count: 1.7">AMD先于Intel推出服务器处理器的双核，结构设计的先进性带来性能的巨大领先，其Opteron核心浮点计算与整数计算领先于Intel Nocona，内存带宽也是AMD最优异的特性之一，CPU温度方面也比Intel有优势，所以很多国内外品牌服务器如Sun、曙光等都采用AMD的CPU。虽然Sun X2100 Server 采用AMD Opteron 146、152、175，是不错的选择，但从性价比考虑，且由于内有数据库(Database)采用Athlon 64 X2提供Dual Core处理器支持，工作更有效率，效能上一点也不比Dual Core Opteron175 逊色。同单内核Athlon 64处理器相比，特定的数字媒体和生产应用在Athlon 64 X2平台上性能最高可提升80%。由于本次DIY服务器主要作网页、电子邮件及数据库使用，从性价比综合比较，笔者选择了AMD Athlon 64 X2。<o:p></o:p><

class=MsoNormal style="TEXT-INDENT: 17.85pt; mso-char-indent-count: 1.7">选择适当的X2产品也是一个重要的问题。究竟哪一款最值得买呢？目前两种AMD处理器Manchester和Toledo双核心芯片。Manchester的每个核心都使用512kB L2高速缓存，Toledo使用1MB高速缓存。下表是各种X2处理器的一些重要特性：<o:p></o:p><

class=MsoNormal style="TEXT-INDENT: 17.85pt; mso-char-indent-count: 1.7">主板的功能大部份来自nVidia nForce 4 Ultra，硬盘方面它支援四个SATA II硬盘接口及两个IDE接口，而且提能提供SATA RAID 0、1及0+1等模式，而且它更内建了Gigabit Ethernet功能，提供10/100/1000Mbps网络接口，而且更拥有NV硬件防火墙，为系统带来充足的网络保安。除了晶片组内建的Ethernet接口外，Tyan亦额外多建一颗Broadcom的Gigabit Ethernet晶片提供Dual LAN功能，对架设服务器来说是不可或缺的功能。主板元件布局合理，939针CPU插槽位于主板的前端，内存4根插槽位于右侧，适合安装在1U机箱里，机箱中部安排一些高速风机向后面的主板吹风，所以散热效果好，Tyan S2865G2NR主板明显在设计的时考虑了1U服务器的散热特点，可以直接承接从前面吹来的冷风，内存也不会对风力造成阻塞，风从内存间隙吹过，不仅冷却了内存，而且还可以继续冷却后面的各个主板元器件，可谓设计合理。<o:p></o:p><

class=MsoNormal style="TEXT-INDENT: 17.85pt; mso-char-indent-count: 1.7">电源并不是简单地将220V交流变换成服务器所需低压直流这么简单，其质量的优劣直接影响到系统的稳定和硬件的寿命。服务器电源必须能应付各种苛刻的工作环境，同时还要求常年不间断地工作。随着CPU的速度提升，硬盘容量和转速等越来越大、越快，功耗就随之升高，对电源的要求就更高了。实践经验告诉我们，电源功率不足或过热，是服务器经常自动重启(Reboot)的一个重要原因。其实也很容易理解，当您的CPU负荷增加、硬盘突然读写大量数据时，因负载变化造成电源电压波动是在所难免的。高品质的电源在设计时充分考虑到这些因素，出问题的可能性就少得多了。<o:p></o:p><

class=MsoNormal style="TEXT-INDENT: 17.85pt; mso-char-indent-count: 1.7">机箱内其他散热风扇的选用也是一门学问。高风量(CFM)散热风扇可有效降低服务器内部温度。散热风扇一般分滚珠轴承、油封轴承两种。滚珠轴承较为耐用，虽噪声略高，但服务器一般在机房中工作，通常采用无人看守远程监控，所以噪声略大也可接受。可从风扇上标明的A（电流）和W（功率）来初步判断风量，数字越大一般风量也越大。建议大家选择Sunon、Nidec、Sanyo、Y.S.Tech等名牌。有兴趣了解各类强力风扇的朋友可到超频专门店网址查询。<

class=MsoNormal style="TEXT-INDENT: 17.85pt; mso-char-indent-count: 1.7">　Sanyo超强力风扇也值得推介，要知道Intel很多原装CPU风扇都是Sanyo提供的。近期Sanyo推出1.5万转4cm电流0.55A风量20.83CFM及24.71CFM的超强力风扇，是1U服务器散热较佳配搭。对于服务器机箱散热风扇，选用风量大的风扇，效果更佳。笔者将1U机箱内原5个散热风扇更换成Sanyo 0.55A/20.83CFM风扇后，实测机箱温度由原来的35度，降低至32.3度。由于CPU采用双核心设计，其温度达到了66度，于是笔者特别在主板CPU 位置前换上Sanyo新推出的9CRA0412J502 1.58万转4 x 5.6CM风量31.8CFM风扇，CPU温度降低到63度。有兴趣的读者可以一试。</o:p><
