了解機房監控系統的雙機熱備功能,讓機房監控更安全

來源：縱橫通发布日期： 2021-02-19

機房監控系統中的監控管理平台軟件，承擔著機房所有設備和環境等監測點的數據彙集處理的工作，是機房監控管理的中樞，軟件實現機房最主要的監控功能，報警功能，還可以根據需要擴充容量管理、資産管理、能效管理等管理模塊，實現監控、管理的一體化。

機房監控系統采用分布式集散结构，各项应用相对独立，一个应用系统发生故障，不影响其他应用系统的正常运作。平台可运行在监控服务器上。客户可以通过监控服务器进入客户端或者IE远程访问，用户可以在客户端上实现各种统计报表、数据分析挖掘、告警管理、能耗管理、权限管理和系统配置管理等。另外，集中监控系统还是数据对外发布的总出口，各种移动终端通过互联网或专用网络可获取集中监控系统发布的数据中心的监控数据。

機房監控系統

在機房監控系統中，集中管理服务器（主备机）负责整体系统的集中管理与调度,收集与处理由区域管理层发送上来的数据和报警。监控服务器可采用双机热备方式设计，确保监控系统的稳定可靠运行。

機房監控系統双机热备功能：

1.兩台服務器互相備份，執行同一服務，一台用于部署數據庫。當主服務器出現故障時，可以由冗余服務器承擔服務任務，從而在不需要人工幹預的情況下，自動保證管理中心系統能持續提供服務，同時保證數據的存儲不會間斷。

2.主機、備機同時獲取上傳的數據，並保持同步。同時備機在主機正常時對被監控設備的下行控制能力被禁止。

3.主機、備機之間通過RS232串口或以太網進行通訊，備機時刻檢測主機健康度。

4.當備機在規定的時間內未收到來自主機的握手信息，則認爲主機已不可用，此時自動釋放端口給備機，並由其接管主機的所有工作。

The light breakfast was taken, and the adventurers moved on. At each step the way grew more and more difficult. Every mile was steeper than its predecessor, and in many instances it was rougher. The rarefaction of the air increased, and rendered the work of breathing more and more severe. The travellers panted like frightened deer, and their lungs seemed to gain little relief from the rest that the Doctor and his young friends were compelled to take at frequent intervals. The last of the huts of refuge was passed, and it seemed only a short distance to the summit. But it required more than an hour's effort to accomplish this final stage. The boys refused all offers of assistance, and struggled manfully on; but Doctor Branson was less confident of his powers, and was glad of the aid of the strong-limbed and strong-handed yamabooshees. All were glad enough to stand on the summit and gaze into the deep gulf of the crater, while their brows were cooled by the clear breezes from the Pacific. They were at the top of Fusiyama, 14,000 feet above the level of the ocean that lay so far below them, eighty miles from their starting-point at Yokohama, and their vision swept an area of the surface of the earth nearly two hundred miles in diameter. East and south lay the broad ocean. West and north was the wondrous land of Japan, a carpet of billowy green, roughened here and there with wooded hills and small mountains, indented with bays and with silver threads of rivers meandering through it. It was a picture of marvellous beauty which no pen can describe. "I should like to know what you make of them," said Lawrence. "Ah well, be you a Fleming?" We have now to see how, granting Epicurus his conception of painlessness as the supreme good, he proceeds to evolve from it a whole ethical, theological, and physical system. For reasons already mentioned, the ethical development must be studied first. We shall therefore begin with an analysis of the particular virtues. Temperance, as the great self-regarding duty, obviously takes precedence of the others. In dealing with this branch of his subject, there was nothing to prevent Epicurus from profiting by the labours of his predecessors, and more especially of the naturalistic school from Prodicus down. So far as moderation is concerned, there need be little difference between a theory of conduct based exclusively on the interests of the individual, and a theory which regards him chiefly as a portion of some larger whole. Accordingly, we find that our philosopher, in his praises of frugality, closely approximated to the Cynic and Stoic standards—so much so, indeed, that his expressions on the subject are repeatedly quoted by Seneca as the best that could be found. Perhaps the Roman moralist valued them less for their own sake than as being, to some extent, the admissions of an opponent. But, in truth, he was only reclaiming what the principles of his own sect had originally inspired. To be content with the barest necessaries was a part of that Nature-worship against which Greek humanism, with its hedonistic and idealistic offshoots, had begun by vigorously protesting. Hence many passages in Lucretius express exactly the same sentiments as those which are most characteristic of Latin literature at a time when it is completely dominated by Stoic influences. J. A. “I thought I saw—but it’s gone!” Larry retorted, lowering his voice also. “The Everdail Emeralds!” Larry repeated the phrase sharply. “Why, Jeff! I’ve read a newspaper story about them, in a Sunday supplement. That’s the matched set of thirty emeralds——” "You are not fit to go," Felipa said resignedly, "but that doesn't matter, of course." Dr. Arbuthnot, a great friend of Pope and Swift, was also one of the ablest prose writers, "The Memoirs of Martinus Scriblerus," published in Pope's and Swift's works, and the political satire of "John Bull," a masterly performance, being attributed to him. "Blank your Captain," roared the voice; "I'm no Captain." "What's that?" said the Deacon, rousing to interest, but carefully putting his thumb down to mark the place where he left off. "O, open it, Maria," groaned Si, "and you'll likely find his name writ somewhere inside." "I do not understand your one thing or your other thing;" answered Turner—"but I know this, that we have paid the tax, and that we will pay it no more—but as for touching what belongs to the London folks—I'll tell you what, if we do set fire to London, by St. Nicholas! if I see my own son Tom taking a penny's worth, I will fling him into the flames!"
