汉英对照:
Chinese-English Translation:

电源是提供电能的装置。因为它可以将其它形式的能转换成电能,所以把这种提供电能的装置叫做电源。电源是将其它形式的能转换成电能的装置。电源自“磁生电”原理,由水力、风力、太阳能等可再生能源,及烧煤炭、油渣等产生电力来源。

A power supply is a device that provides electrical energy. Because it can convert other forms of energy into electric energy, the device that provides electric energy is called power supply. A power supply is a device that converts other forms of energy into electrical energy. The power source is based on the principle of “magnetoelectricity”. It is generated from renewable energy such as water power, wind power, solar energy, and coal and oil residue.

电源是将其它形式的能转换成电能的装置。电源自“磁生电”原理,由水力、风力、海潮、水坝水压差、太阳能等可再生能源,及烧煤炭、油渣等产生电力来源。常见的电源是干电池(直流电)与家用的 110V-220V 交流电源。

A power supply is a device that converts other forms of energy into electrical energy. The power source is based on the principle of “magnetic power generation”, which is composed of renewable energy such as water power, wind power, tide, water pressure difference of dam, solar energy, coal burning, oil residue, etc. The common power supply is dry battery (DC) and household 110V-220V AC power supply.

计算机电源是一种安装在主机箱内的封闭式独立部件,它的作用是将交流电通过一个开关电源变压器换为 5V,-5V,+12V,-12V,+3.3V 等稳定的直流电,以供应主机箱内系统版,软盘,硬盘驱动及各种适配器扩展卡等系统部件使用。通俗来讲就是,一个电源坏了,另一个备份电源代替其供电。可以通过为节点和磁盘提供电池后援来增强硬件的可用性。HP 支持的不间断电源 (UPS),如 HP PowerTrust,可提防瞬间掉电。 磁盘与供电电路的连接方式应使镜像副本分别连接到不同的电源上。根磁盘与其相应的节点应由同一电源电路供电。

Computer power supply is a kind of closed and independent component installed in the main box. Its function is to change alternating current into 5V, – 5V, + 12V, – 12V, + 3.3V and other stable direct current through a switch power transformer, so as to supply the system components in the main box, such as system version, floppy disk, hard disk drive and various adapter expansion cards. Generally speaking, one power supply is broken, and the other backup power supply replaces its power supply. Hardware availability can be enhanced by providing battery backup for nodes and disks. Uninterruptible power supply (UPS) supported by HP, such as HP powertrust, can be used to prevent power failure in an instant. The disk and power supply circuit shall be connected in such a way that the mirror copy is connected to different power supplies respectively. The root disk and its corresponding nodes shall be powered by the same power circuit.

特别是,群集锁磁盘(当重组群集时用作仲裁器)应该有冗余电源,或者,它能由群集中节点之外的电源供电。您的 HP 代表可提供关于群集的电源、磁盘和 LAN 硬件布局方面的详细信息。

In particular, a cluster lockable disk (used as an arbiter when reorganizing a cluster) should have redundant power, or it can be powered from a power source other than the node in the cluster. Your HP representative can provide detailed information about the power, disk, and LAN hardware layout of the cluster.

目前许多磁盘阵列和其他架装系统含有多个电源输入,它们应部署为设备上的不同电源输入连接到带有两个或三个电源输入的独立电路设备上,这样,一般情况下,只要出现故障的电路不超过一个,系统就能继续正常运行。因此,如果群集中的所有硬件有 2 个或 3 个电源输入,则要求至少有三个独立的电路,以确保群集的电路设计中没有单点故障。

At present, many disk arrays and other rack mounted systems contain multiple power inputs, which should be deployed as different power inputs on the device connected to independent circuit devices with two or three power inputs, so that, in general, as long as there is no more than one failed circuit, the system can continue to operate normally. Therefore, if all the hardware in the cluster has two or three power inputs, at least three independent circuits are required to ensure that there is no single point of failure in the circuit design of the cluster.
