大量数据库操作小网站在执行大量数据库操作时,也会影响网站打开速度,这里使asp+access结构的网站尤为明显,尤其是同时有大量用户提交评论时,就操作数据库锁死,导致网站打不开。比如博客在发布文章时会有几分钟时间使网站速度大打折扣。
页面上用大图片和FLASH我们知道图片是拖慢网速最重要一个因素,图片经过处理,可以使图片空间变小,图片都经过处理,但导致有部分图片清晰度不够,否则很多的图片一开始都会占用很多空间又使网站打开速度变得很慢,同样FLASH也是一个道理。
机房建设和运营
符合国际标准的电信级机房是IDC最基础的设施,机房建设和运营中要考虑的技术问题有:
电力供应 大规模机房面积供电容量的计算、n+1的冗余供电能力、UPS负载能力、电路自动切换能力、电缆的阻燃考虑、开关切换等。
温湿度控制 上千台高密度放置的服务器在运行中会引起温度上升,而温湿度对于服务器的正常工作和使用寿命都有很大影响,因此采用最合理的送风方式、智能的温湿度控制和告警都是设计中的关键。
机柜和线缆 独立供电、主/备电源、各种机柜配件、各种走线(五类线、单模/多模光缆、有线电缆)。
消防设施 防火和阻燃材料,温感和烟感火灾监测报警系统,气体灭火装置和完善的消防措施。
安全设施 能适合不同安全策略的门禁系统,全方位无死角闭路电视监控系统,红外报警系统,24小时的保安值守和紧急处理措施。
网络建立和维护
各种网络资源和高速带宽资源是IDC服务能力和服务品质保证的基础,在网络的建立和维护中,需要最优化的网络设计、路由设计和网管能力保证。● 网络设计 网络拓扑结构的设计要求达到各层节点完全冗余,数据传输和交换快速无阻塞,网络的扩展性好,整体网络结构合理。各种接入 光纤、DDN、帧中继、DSL等。路由技术 各种路由策略、动态路由协议。网管技术 网络性能的监控、故障告警、趋势估计及各交换和路由节点的健康状况、紧急状况的用户自动告警系统等。
