今天,一星期只运行5天的网络无法满足公司运营的要求,而只有个别公司才需要容错特性的想法也早已过时了。随着Internet和Intranet的普及,所有用户现在都需要7×24的网络连通。国内的CTO们一致认为如何使今天企业网络保持不间断运行是最需要优先考虑的问题。信息技术经理们需要事先规划采用何种容错系统,才能保证能够满足高可用性要求。扩充服务量与非功率因数校正的UPS相比,使用康柏高效的功能因数校正的不间断电源系统能够保护数量是典型配置服务器数量两倍的用品。“功率因数”一词表示设备的用电效率。说得更详细一点,“功率因数”就是指“有效”功率一或瓦数所占的比例。在许多情况下,设备的功率以VA(电压×电流强度=VA)计算。而硬件消耗的有
Today, a network that runs only five days a week does not meet the company’s operational requirements, and the idea that individual companies need fault tolerance is outdated. With the popularity of the Internet and Intranet, all users now require 7 × 24 network connectivity. Domestic CTOs are unanimous in their opinion that the most important issue to consider is how to keep today’s corporate networks operating uninterrupted. Information technology managers need to plan in advance what kind of fault-tolerant systems to be able to meet the high availability requirements. Expanding Service Volumes Compaq’s non-disruptive power systems that use Compaq’s highly-efficient, factor-corrected UPS can protect supplies up to twice the number of servers typically configured, compared to non-power factor-corrected UPSs. The term “power factor” indicates the power efficiency of the equipment. To put it in more detail, “power factor” refers to the ratio of “effective” power or wattage. In many cases, the power of the device is calculated as VA (voltage × current intensity = VA). The hardware is consumed
