Datacenter migration, how to choose the right time to proceed?
Datacenter migration,With the development of the era and interconnection, in order to keep abreast of the trend of the times, it is inevitable that technology will also need to make development and change. Therefore, whether it is a continuous profit small business, and a non-profit organization expanding to the unfamiliar domain, IT equipment needs to expand. To alleviate the potential delay problem, determine which applications work together and when to work, and plan the migration time, as short as possible to separate them.

Datacenter migration, how to reduce the cost of data center?
Datacenter migration, although organizations have higher requirements for data centers, IT managers do have the means to work within strict budgets.
Today, organizations say their data center budgets are shrinking even as performance expectations continue to improve.While overall IT spending is expected to grow 4.5 per cent in 2018, data centre spending is expected to grow only 0.6 per cent.Forecasts for 2019 actually predict a decline in IT budgets.At the same time, the demand for data center capacity will only grow, especially as new technologies such as the Internet of things, blockchain and artificial intelligence become more and more common in business environments.

機房建置,如何解决传统硬件故障的挑战?
機房建置, 對於今天的企業組織機構而言,仍然在堅持使用傳統系統的一大主要原因便是:這些企業有相當一部分的關鍵型任務工作負載仍然還在哲學傳統系統上運行,而採用此方案對於這些企業組織而言是有利的。但是,儘管有這些傳統遺留系統的功能對於它企業組織機構而言意義重大,但一大不容忽視的現實問題則是:這些傳統遺留系統正在迅速老化。這也就意味着它們可能會逐漸變得不那麼可靠,並且更容易出現故障。而一旦這些傳統系統硬件設備出現故障運行失敗時,其所帶給企業組織的影響可能是毀滅性的。而在本文中,我們就將幫助廣大讀者朋友們詳細瞭解如何制定虛擬化計劃,以便能夠主動的防止系統故障所帶來的破壞性結果,並進一步的幫助貴公司節省更多寶貴的資源。當涉及到它企業組織機構的傳統遺留系統時,可以說存在着很多的變數:這包括您企業數據中心所使用的硬件設施,運行在其之上的傳統操作系統以及運行在其上的應用程序。您企業將仍然繼續維護這些傳統遺留系統的原因就在於,這些傳統系統對您企業的業務至關重要。這可能是關鍵型的任務,有助於讓你輕易的員工順利完成業務目標。的確,企業的傳統遺留系統涉及到存在着很多的變數。但所有的這些傳統遺留系統都至少有一個共同點,而這一共同點無疑又是非常重要的(甚至是最爲重要的因素),即:這些傳統遺留系統正在迅速的老化。隨着企業組織的這些傳統系統的逐漸老化,它們將變得不太可靠,而且,硬件的使用壽命是有限的,但在其之上運行的軟件和應用程序的壽命則往往要長得多,通常是底層硬件使用壽命的三到五倍。您企業可能已經遇到硬件故障或對硬件支持的需求增加的難題了。您甚至可能已經在搜索更換相關部件的方案或開始調查相應的替代品了。而如果你企業目前尚未遇到傳統硬件方面的困難,那麼我們建議您需要意識到這只是一個時間的問題。對於那些已經意識到上述硬件故障的出現只是一個時間問題的企業組織來說,這意味着他們至少現在還有時間來採取積極的應對措施,他們可以將相關項目的重要性降低,以支持那些更加緊迫的項目。但我們卻遇到過很多企業都分別表達了類似的敷衍觀點:“硬件故障對我們來說目前還不構成問題,我們稍後可能會有相應的跟進措施。”而現實情況則是,一旦傳統硬件出現故障,這些企業往往會後悔爲什麼沒有提前進行規劃,一旦傳統硬件出現故障時,就再也沒有後悔藥了:屆時,讓系統重新運行起來的將變得非常緊迫,這對企業業務的成敗至關重要。那麼爲什麼當前仍有這麼多的企業對於潛在的問題如此敷衍呢?爲什麼企業在其會影響到企業營收甚至還將承擔相應責任時仍然沒有爲其傳統舊系統提前制定相應計劃呢?在本文中,我們將與您一起探討當前企業遲遲拖延,未對其傳統遺留系統採取保護措施的最常見的原因,並介紹爲什麼提前制定計劃是最好的應對方式。文章將深入討論延遲實施這些計劃所將帶來的相關的成本以及他們如何定期影響到企業業務。最後,我們與您分享關於企業如何制定定製化的計劃方案,以確保您的傳統遺留系統成爲商業機會的來源,並提高投資回報率,而不是您企業的“定時炸彈”的最佳實踐方案。爲什麼企業會延遲實施針對傳統系統的應對措施儘管存在與硬件故障相關的風險,但仍有許多企業組織遲遲沒有對其傳統遺留系統採取下一步的應對措施。究其原因何在呢?1、預算成本問題通常是最大的障礙。由於企業的它預算有限,導致獲得進一步投資於傳統遺留系統的批准可能很困難。企業通常很少或根本沒有爲這些後備系統分配資金,因此,讓我們面對現實吧,這些傳統遺留系統已然不是企業會承諾提供無條件支持的最具魅力的項目。2,優先原則企業在保持緊跟最新技術領域發展潮流的挑戰之下,會使得其對於傳統遺留系統的維護傾向於落後。傳統遺留系統不是新潮技術,並不新鮮,但這些傳統遺留系統所執行的往往是企業的關鍵任務,因此,企業在工作中往往會秉承着“如果沒有壞掉,不要這樣修理”的心態。只要其傳統遺留系統能夠繼續維持運行,那麼其他領域的就會被優先考慮。

Datacenter migration, how to choose PDU power supply cabinet
Datacenter migration, not only to ensure the security of the data center under high temperature and rainy weather, stability operations, but also reduce operating costs of enterprises overall under pressure, but many in the bidding process is not the PDU with UPS as single row, column head cabinet, cabinets and other equipment, PDU parameters also is very not clear, even some just indicate the power supply socket, this will cause a lot of late work: matching with equipment, non-standard distribution, shortage of budget, etc., the above situation is called bids from both sides don't know how to choose matching PDU power?

企業機房建置,如何增強基礎架構的可擴展性?
機房建置,自數據中心出現以來,企業的它經理們就一直糾結於努力尋求對數據中心資源進行配置處理的最佳方式。而伴隨着服務器虛擬化,雲計算和大數據等技術的發展,這一過程變得更加複雜。而在本文中,業內的相關專家就將幫助我們廣大讀者朋友們就如何更好的解決貴公司在服務器硬件策略方面的管理難題進行解疑,並還將爲您介紹關於如何識別和解決數據中心網絡性能問題的相關方法,以及實施服務器規模化擴展的優缺點,以便幫助您瞭解如何採購可擴展的虛擬基礎架構。識別和解決網絡性能問題企業數據中心的它經理們花時間來調查可用於監控網絡I / O的方法,並確定可能導致網絡速度變慢的原因是非常值得的。如果企業應用程序的所有者報告稱:網絡連接速度慢,那麼確保其原因不是由廣域網中的瓶頸所導致的是至關重要的。網絡性能不佳通常可歸因於虛擬化之外的原因。可能存在尚未報告或發現的停機中斷或路由問題。另一個亟待檢查的領域是IP配置。而一些簡單的工具如萍,pathping,路徑跟蹤程序和網路資訊查詢在診斷網絡問題時仍然有用。最常見的問題之一是錯誤或不正確的域名服務器(DNS)配置。另一個亟待檢查的領域是虛擬機(VM)中應用程序的配置。查看是否存在會顯著降低網絡性能的設置或選項,也許是應用程序的輪詢網絡,以查找外部網絡組件的可用性——那麼這可能會導致不必要的網絡流量。一旦你企業排除了上述這些潛在的問題,就需要確認優化組件是否配置正確。接下來,檢查網絡問題是否僅影響相關虛擬機或同一主機上的所有虛擬機。這也是確定相關問題是否特定於應用程序所有者的虛擬機或者是否是系統性問題的好方法。大多數虛擬機管理程序供應商均提供了相應的網絡工具,以方便企業客戶監控進出虛擬機的流量。例如,VMware公司就提供了一款名爲esxtop的實用程序,可以查看網絡統計信息,並排除網絡性能問題。這些實用程序允許數據中心的運營管理人員查看虛擬機實際使用的網絡帶寬,以及是否檢測到物理系統出現大量的網絡數據包的被丟。它們還能夠顯示系統的發送和接收速率。當一款機器發出數據包,但未收到確認時,可能表示網絡接口卡(NIC)的算法存在問題,稱爲反向NIC團隊問題。在這種情況下,已啓用高級網卡綁定,雖然數據包通過一個網絡層離開物理主機,但它們通過錯誤的物理交換機返回到主機,並返回到錯誤的NIC。像這類嚴重的問題可能需要更廣泛的調查。在某些情況下,可能會導致放棄特定的NIC組合策略,這對於更廣泛的網絡來說被認爲是不可靠的。隨着整合比率的增長,可以做大量工作來改進和監控虛擬機的網絡性能。最佳優化的關鍵在於遵循虛擬化供應廠商的最佳實踐方案,同時對其進行修改以適應企業網絡的獨特流量特性。最關鍵的部分是瞭解你企業的虛擬機和更廣闊的物理環境之間的關係。橫向或縱向規模化擴展:如何通過數據中心升級實現進一步的發展演變在它領域,舊的問題最終會演變成新的問題,這個道理在數據中心服務器方面正在發揮作用。根據技術商業研究(創業)有限公司公司數據中心研究部門高級分析師基督教佩裏表示:“我們當前正再次看到企業對其系統實施縱向規模化擴展的興趣的增強,而這一方案曾一度處於下滑趨勢。”自數據中心出現以來,企業的它經理們一直在努力處理如何最好地配置其資源的問題。而他們的這個選擇方案基本上是在採購更大的硬件或更多的硬件之間:橫向或縱向規模化擴展嗎?1,服務器橫向擴展的優缺點分析服務器的橫向擴展的概念意味着向系統添加更多節點或購買更多硬件。例如,一家公司可以從一款Web服務器系統發展到三個。在極端情況下,數百臺小型計算機被配置爲集羣,這些集羣足夠支持大型數據中心的計算能力。橫向擴展通常很簡單。企業可以購買新系統並快速啓動。該方法也很靈活:可以以一種看似有限的方式添加系統,儘管其最終將需要更多的數據中心空間。實際上,橫向擴展的方法在雲服務供應商中很受歡迎,因爲該方法可以構建能夠支持數千個客戶和PB級數據存儲的海量數據中心。Facebook Inc .公司的開放計算項目就鼓勵橫向擴展服務器。該公司並不是依賴來自諸如惠普,IBM和甲骨文等傳統服務器廠商的特殊用途的系統,而是將通用硬件設備捆綁在一起,並構建巨大的數據中心。包括蘋果,Facebook和谷歌在內的網絡領軍企業都選擇了這種方式來支持他們的業務。當然,橫向擴展系統也有其缺點,首當其衝便是複雜性。太多計算機的連接會增加管理的複雜性,並且您必須支持更復雜的編程模型,由於存在多個本地系統,因此會在節點之間出現吞吐量和延遲問題,所以很難進行故障排除。

What are the factors that must be considered in datacenter migration?
Datacenter migration is not a simple thing, the construction of data center is an integral structure, any details, ignore is likely to lead to the happening of the problem, and involved in the problems of details, and eventually lead to its design and construction of the result often is not very ideal, causing delays and need to rework, to make matters worse, it will be a troubling problem for a long time, the merits of the planning and design, and only after the system is running to make objective assessment, a lot of problems to after a long time, even a life cycle of equipment or system to be exposed, to avoid data center construction completion of delivery,Due to the delay in the construction period caused by the failure to consider the problems during construction, the rework is required. The following are the key issues to ensure that the data center planners adhere to the correct direction.
