服务器的U代表什么?42U机柜又能够放多少台服务器?

一、什么是1U?

       随着企业信息化的快速发展,需要越来越多的服务器。 在计算机机房有限的空间内,如何合理地规划和实施,对我们来说,必须注意这些问题。 与塔式服务器相比,机架服务器配置灵活,计算密度高,具有节能、维护成本和环境成本等优点。 这些优点为大中型信息系统的建设提供了广阔的发展空间。

1、那么什么是1U服务器?

1U服务器是一种所谓的高密度,低成本的高可用性服务器平台,1U服务器机箱高度等于4.45厘米,这是3×4.5CM一个3U。

       U(unit的缩略语)是一种可以表示一个组合式机架进行外部结构尺寸的单位,详细分析尺寸由作为中国业界研究团体的美国企业电子技术工业发展协会(eia)决定。其规定的尺寸是宽(48.26cm=19英寸)与高(4.445cm的倍数)。由于宽为19英寸,所以我们有时也将满足学生这一制度规定的机架部分称为“19英寸机架”。厚度以4.445cm为基本建设单位。

       2、服务器大小规格:1U =4.45厘米,2U =8.9厘米,3U =4.45厘米* 3,4U =4.45厘米* 4。U并不是一个服务器的专利,最早是用于进行通讯信息交换的机架结构,后备引用到企业服务器的机架。目前我国作为一种非正式标准可以用在机架结构上,包括管理规定的螺丝大小,孔距,划轨,等等

       1U和2U是服务器的厚度,1U可能相当于机柜的两个小格子,2U是四个格子。 1U为4.445cm。

       二、1U,2U,4U,哪种服务器更好?

       最常见的机架服务器为1U,2U,4U,现在的市场是普遍的服务器1U和2U,那么什么是最好的?事实上,没有最好的产品,只有最适合的产品,每个产品都有自己的特点,只要我们充分了解产品和我们自己的需要,您可以轻松地选择最合适的机器。

       1、1U、2U服务器都有自己什么发展优势?

       1U服务器的优势:节省空间,成本低廉的托管;

       2U服务器资源优势:扩展发展空间大,散热性好;

       选择2U服务器是一个不错的选择,如果您的服务器需要加载4个以上的硬盘等;如果服务器不需要加载太多的外部附件,那么1U服务器是完全可以胜任的,而1U的机房托管是最合适的,标准的服务器散热问题在专业的IDC数据中心恒温,湿度环境也可以很好的处理。

       2、什么是1u 服务器?

       1U高度是有限的,对于有特殊要求的零件,会增加硬件和附件筛选的总体成本的难度。可以说,1U服务器是一种高密度,低成本高可用性的服务器平台,是专门针对行业的具体应用和高密度计算环境而设计。

       1U服务器网络空间发展有限,在扩展性和散热性有一定的限制,一般都无法得到实现太完整的设备不断扩张。相比于1U服务器技术产品,2U高度适中,扩展性(硬盘数据存储用户数量、扩展槽、电源)有了明显的增强。其散热也得到了更一步的改善。如果我们采用不同服务器托管服务业务则1U服务器比2U服务器托管教育费用高。但具体情况选择几U服务器,需要学生根据企业项目管理类型、项目建设规模等进行分析选择,以避免服务器信息资源与资金的浪费。

       三,共同柜尺寸是多少? 42U机柜多少服务器可放?

       之所以要规定进行服务器的尺寸,是为了使服务器可以保持一个适当的尺寸信息以便学生放在铁质 或铝质的机架上。机架上有没有固定网络服务器的螺孔,以便它能与企业服务器的螺孔对上号, 再用螺丝加以固定好,以方便我们安装每一部系统服务器所需要的空间。

       指定的大小是服务器的宽度(48.26厘米=19英寸),高度的倍数(4.445厘米)。 由于宽度为19英寸,有时满足这一要求的机架也称为“19英寸机架“。 厚度是厘米4.445厘米。。

       1、42u 柜子的大小是多少?

       42U是高2米,0.6米,宽0.8米深处服务器机柜,可以是2米,0.6米宽和0.96米深服务器机架;

       2、一个42U机柜系统可以放多少台服务器?

       内阁把一个服务器的限制,42U高度机架,并不代表实际能放42级1U的服务器,因为你必须保持热量和移动的空间,你必须要考虑的电源,你必须要考虑整体散热,而且在一定会有走来走去行空的地方,并把另一组别处交换机,防火墙和其他显示器。

       比例某牌子42U标准以及机柜,能放的最多时间可达18台20服务器。为什么是20台,1U服务器与1U服务器系统之间要留下一个散热的空间,同时通过机柜设备里面要放1台交换机,也需要2U的空间。

        如果是2U服务器,输入10台左右,加上放置交换机,路由器等设备。

       3、服务器的电量

       内阁提供有限的电力量,当服务器的电力消耗越大,服务器就越少。 一个柜子一般能提供10华氏度的电,但有些柜子能提供更高的18华氏度的电。

       220V * 10A = 2200W。也就是说,只要你把服务器不超过2200W的总功率,服务器功耗还取决于是否满负荷运行非服务器的数量。一般非满载功耗比服务器上的主题的额定功率。

       所以机柜放服务器的多少,也需要进行计算系统功率
