機房建置,業界觀點專欄的記者採訪了來自InterOptic公司的首席執行官蒂姆·迪克森(Tim Dixon)先生,就光學產業在當前的IT業界所扮演的日益重要的角色問題進行了深入的訪談.InterOptic公司是一家數據互連公司,幫助全球財富500年強企業和政府相關機構的客戶管理其它網絡的帶寬,互操作性和複雜性。憑藉着其數十年的光學領域的專業知識,該公司爲其遍佈全球的廣大客戶提供了一系列數據互連解決方案,包括一整套的行業標準的光學硬件,而這些硬件與原始設備製造商所使用的技術相同,但成本較低。
業界觀點:數據中心業界的光學究竟是什麼?
蒂姆·迪克森:在數據中心的背景下,光學是光纖電纜和激光發射器/接收器的簡稱,它們是實現網絡,計算和存儲元素之間互連的大多數數據路徑。
業界觀點:當前的企業數據中心要如何才能從集成的光學技術設計中獲益呢?
蒂姆·迪克森:使用激光進行數據傳輸的技術方案可以追溯到上個世紀70年代,但在21世紀初,我們看到了可插入光學技術的快速普及,該技術提供了在部署數據速率和整體帶寬方面的靈活性,以及更容易的設備升級和維護。這方面技術的發展,加上縮小規模,以及技術成本和功耗方面的進步,都使得今天的數據中心大大受益。那些投資於光學網絡硬件和設計(例如光學無線電收發器)的企業組織將提高其它網絡的可靠性,傳輸處理速度和互操作性,以滿足日益增長的帶寬和擴展需求。
業界觀點:當前,有哪些技術和趨勢在擴展數據中心網絡的極限呢?而這些技術和趨勢所帶來的結果又是什麼呢?
蒂姆·迪克森:光學的信噪比信噪比(信噪比)帶來了一大限制,其限制了可以通過一個單一光纖所傳輸的聚合數據。近十年來,我們一直在積極的探索測試這個極限,首先是在長距離之間(數據中心之間)傳輸的測試,現在測試的則是短程的(數據中心內部)傳輸連接速度爲200 gbps及以上,以滿足5 g,物聯網,大數據,量子計算和其他新興技術的需求。這種需求增加了對速度,正常運行時間,可靠性和有效數據傳輸的需求。在數據中心,它導致平行光纖路徑的擴散,必須終止,監視,管理和處理每臺設備。電子領域的相關成本和複雜性正在持續增加,未來的數據中心設計需要採用更加簡單的,低成本的方式,並將這種複雜性的一部分分配到光纖層中,以獲得更高的吞吐量。
業界觀點:那麼,究竟是哪些因素決定了“哪種光學解決方案或項目”纔是最好的呢?
蒂姆·迪克森:的確,就像我們能夠在失去光澤的鏡子裏看到模糊的反射一樣,產生和傳遞光的元素對它的完整性會有很大的影響。對於設計元素的選擇以及測試,監控和供應鏈的可追溯性,所有的這一切要素結合在一起,提供了一個高性能的光學組件,其將在這個領域持續幾十年。
業界觀點:考慮到今後的帶寬需求只會不斷的增加,那麼,數據互聯的未來會怎樣呢?
蒂姆·迪克森:這個問題其實是與數據中心的“極限延伸”有關的。今天的數據中心在許多方面繼承了典型的計算機和網絡架構的設備設計方面孤島筒倉的方法,以及OSI模型的分層偏差。這種細分的,盒式的思維方式是一種經典的系統方法,但是,當您從全局來看時,其並非總是最有效的,最有創意,最符合成本經濟性的方法。我相信,你企業所需要的是通過一種更加全面的方法來處理未來的數據中心——這將是一種充分整合了我們所今天看到的邏輯和物理邊界的方法,各種光學元素都將在其中發揮作用。
業界觀點:企業如何解決快速且可負擔地增加數據中心帶寬的問題嗎?
蒂姆·迪克森:如果我們從近期來看的話,千萬不要把自己逼到牆角,讓自己陷入兩難的境地。我們目前已經看到了企業數據中心業界有朝着銅纜光纖互連發展的趨勢。這些解決方案雖然現在很便宜,但其在總體吞吐量,傳輸距離和路由多樣性方面都遇到了瓶頸。我們驚訝地發現,在當前企業的數據中心中,很少有副總裁或CIO關注硬件的生命週期成本。但事實上,在這種所謂“無聊的東西”上做出正確的決策可以幫助企業組織節省高達數百萬的資金,並促進其他關鍵它項目的成功。我們建議企業數據中心業主們不妨考慮尋找品牌相當的硬件供應商,這些硬件供應商的產品的性能表現甚至超過了思科和惠普等原始設備製造商,但他們的成本僅佔到後者的一小部分。
業界觀點:光學如何影響雲服務嗎?
蒂姆·迪克森:在我們看來,“雲服務”只不過是部署計算和存儲資源的地方。任何雲數據中心的基礎設施看起來其實都與全球財富1000年強企業內部的數據中心驚人地相似。
業界觀點:在企業數據中心的網絡環境中,是否會有一個“合適的時間”來取代光收發器嗎?
蒂姆·迪克森:對於我們的客戶而言,我們並不採用“替換/取代”這一說法,而更加傾向於採用“重新部署”這一術語。我們產品的使用壽命和可靠性應該意味着企業客戶永遠不需要更換它們。我們有來自美國聯邦政府機構的龐大的客戶羣部署,這些客戶採用我們的光學系統解決方案已經有近十年的時間了。它們只是被拔掉並在網絡中使用得更遠,這些更遠的網絡的帶寬需求更少,並且是那些早期的光收發器的一個很好的匹配。然後,隨着網絡和數據中心核心部署新的和更高性能的體系架構元素,它們可以遷移到更高吞吐量和更高性能的收發器。
業界觀點:您觀察到當前在大型企業數據中心的最大的趨勢是什麼呢?
蒂姆·迪克森:我們所觀察到的最大趨勢之一是從大型數據中心遷移遠離的趨勢。當然,我們目前仍然能夠看的五家或六家超大型的數據中心,但更多行業細分的企業則正在逐步遷移到採用微型數據中心。當貴公司有需要實時處理,且低延遲的應用程序,例如,對於在線網絡遊戲和高頻交易的情況,尤其如此。如前所述,在未來十年內,一套更全面的設計方法應該是適用的:數據中心將不是採用“一刀切”或“統一的規則”,而是偏向於更加定製化的,並且是針對每個行業和企業的具體應用程序的需求。
業界觀點:對於業界當前對於光學的一些常見的誤解,您有什麼想要澄清的呢?
蒂姆·迪克森:當前業界所廣泛流傳的一種說法是:所有的光學都是一樣的,但事情遠非如此。我們領導團隊中的每位成員都致力於光纖網絡領域都已經有20年的歷史了。當我們在貝爾實驗室,AT&T公司,羅克韋爾等公司設計早期的系統和解決方案時,我們顯然曾經做出過相當重要的選擇和權衡。即使在今天,我們在決定如何選擇組件,分析和測試關鍵參數,以及我們如何進行編碼等等方面,都有助於我們提升數據中心和網絡的性能和可靠性,因此在企業客戶滿意度方面也帶來了很大的差異化體驗。事實上,很少有(如果有的話)OEM在設計和部署光學硬件時提供如此程度的專業知識,持久性和個性化的服務體驗。

Datacenter migration,High speed Ethernet is rapidly becoming a network specification as the customer data center servers are increasing the amount of traffic from new, smarter applications, Internet devices, video, and so on.
According to IDC data, the overall 100Gb Ethernet revenue in the first quarter of 2018 increased by 83.8% to $742 million 500 thousand in the first quarter, and the first quarter port shipments increased by 117.7% over the same period. Dell 'Oro Group researchers say that the shipments of 100G Ethernet ports are expected to reach 12 million this year, compared with about 1 million on 100G Ethernet ports in 2016.
Sameh Boujelbene, senior director of Dell 'Oro Group, says many factors have driven the demand for speed up of data centers, such as the huge growth of super large networks from Google, Amazon and Facebook, as well as the price and performance of 100G products.
A recent study by PwC further explains why high-speed networks are needed. "As companies gradually break away from traditional enterprise data centers, workload becomes increasingly unitary. "They're becoming more decentralized, more mobile, and more like workloads typically associated with very large-scale environments," PwC writes. "In the next 1-3 years, almost all major workload will be transferred from internal deployment to public cloud. Applications will be more dependent on the network, and because of the distribution and dynamics of the workload, the network will become more important.
Roland Acra, senior vice president and general manager of CISCO's data center business group, says the demand for high-speed ports and more data driven from the dense edges of the network are pushing the backbone to upgrade.
"It is mainly driven by the evolution of the network interface card NIC on the server.  Most server connections are basically between 1G and 10G. Now, the server that connects to the top switch has changed a lot from 10G to 25G or 50G, which makes the overhead uplink want to reach higher density, 100G, "Acra said.
From 10G to 25G to 100G Ethernet
"The price of 25G is basically the same as that of 10G and 100G. The use of four channel 25GE, 100GE backbone platform requires less wiring, and lower space requirements and costs. Backward compatibility provides an additional choice for simplifying conversion, while extending the value of current assets, "CISCO said.
"Cloud and software-defined architectures are shaking the Ethernet switch and router markets," wrote Petr Jirovsky, IDC's global network tracking research manager. "The continuing price decline and the growing difference between the cloud and communication service providers and the purchase preferences of the enterprises have created a challenging environment for the suppliers, as well as the opportunity for the end users."
Cisco, Juniper, Arista, HPE and HUAWEI aim at data center.
Cisco, Juniper, Arista, HPE and HUAWEI are only a handful of vendors that actively seek market opportunities for high-speed and traditional Ethernet. Juniper recently launched EX4650 High Density 25/100 Gbps Switch, which supports 48 100G Ethernet ports, or 48 25G ports, and eight 100G uplink.
But the driver of 100G is only the beginning of high-speed Ethernet. Dell Oro reported earlier this year that it is estimated that by 2020, 400G will account for 20% of the exchange revenue of data centers. It is estimated that in the next five years, the higher speed of 100G, 200G, 400G and 800G will increase significantly.
"In December 2017, Broadcom announced the launch of a 56G SerDes-based Tomahawk 3 chip with innovative technology and Nephos," Boujelbene said. "We expect commercial chips based on 56G SerDes to boost shipments of 200 Gbps and 400 Gbps, with 400 Gbps accounting for the majority. By 2020 to 2021, we expect 112G SerDes to push another speed upgrade cycle to drive 800 Gbps port shipments, plus another wave of 200 Gbps and 400 Gbps shipments.
Cisco's Accra says there are two to three years to go before the 400 gigabytes, or at least until the 400 gigabytes plummet is attractive enough. "400G is still a concern for cloud and service providers. CISCO has not taken the 400G link as a priority. "
However, Juniper seems to want to achieve faster 400G Ethernet speed than now. (Juniper is looking forward to becoming the first person in 400GbE)

機房建置,數據中心的建設和運營成本越來越高。而根據數據中心所在的位置,其建設成本每兆瓦約爲700多萬美元。電力成本佔持續運營成本的70% ~ 80%,而美國電力成本平均爲每千瓦時0.0658美元,其價格從最高的馬薩諸塞州的0.1475美元到最低的蒙大拿州的0.0473美元不等。調研機構Gartner公司表示,由於人們對區塊鏈,人工智能和物聯網等技術和產品的需求增加,數據中心每年運營的成本增加至少10%。這些都是一切按計劃運行,並且沒考慮運行效率或設備損壞或需要更換時會發生什麼樣的情況,也沒有考慮相關的停機時間,維修成本,甚至數據丟失或業務中斷的影響。
企業管理人員關注利潤,這對於這種投資水平來說並不奇怪。當他們考慮數據中心運營時,需要考慮控制成本,同時確保數據中心爲組織提供真正的價值。如上面的統計數據所示,在考慮成本時,所有企業都需要對數據中心設備和冷卻設備的能源消耗這一關鍵領域進行考慮。除此之外,任何可能對數據中心運營產生負面影響的事情,包括設備報廢退役,事故,數據泄漏或環境問題,甚至由於過冷而導致能源使用效率低下。這些會耗盡資源,並增加運營成本,使許多企業高管對數據中心的成本居高不下感到擔憂。
如今的數據中心很少是一樣的,都在不斷髮展和改進。隨着計算需求的發展和存儲以及服務器技術的不斷改進,需要更新,更改和刪除設備。每次設備的修理,移動還是升級,都可能改變數據中心的成本結構。這使得無法通過使用人工流程來清點資產和評估運營狀態。
雖然不可能爲擁有或運營數據中心的組織消除這些成本,但可以通過優化數據中心以儘可能實現高效,以便組織支付最少的能源成本,在資產失敗之前或者過時之前刪除或替換資產,並在可能損壞設備或造成更多麻煩之前立即解決設備或環境方面的問題。否,則成本可能會失了控。
最佳實踐:實時監控
保持成本,跟蹤資產和實現此優化的最佳實踐是在整個生命週期內實時監控設備,從部署到運營和維護,再到資產退役的那一刻。這可以控制成本,確保設備和其他資源的最佳性能,並且對於許多企業而言,遵守PCI數據安全性,健康保險流通與責任法案(HIPAA)或服務組織控制(SOC)等相關標準以確保安全性和數據的可用性。
受實時監控影響的典型數據中心成本包括:
•用於溫度和溼度控制的能源
•購買新設備以替換過時的設備
•購買新設備以更換因泄漏,故障或環境條件變化而損壞的設備
•非工作設備造成的停機時間
•購買新設備以在現有設備未經優化和充分利用時擴大容量
•實時監控使數據中心管理人員能夠理解每個問題以及它們如何影響運營和成本
作爲運營成本的最主要的部門,能源使用是組織可以優化來降低成本的關鍵領域。監控能耗和風扇速度等事項將有助於數據中心管理人員瞭解數據中心如何運作以及在何處進行調整。有關環境條件的實時更新可以在潛在問題升級之前進行識別,例如火災,設備過熱或冷卻水或冷卻液泄漏,並且不再需要過度冷卻數據中心,以免因設備過熱而造成損壞。通過實時傳感器跟蹤溫度和設備性能,如果溫度發生劇烈變化,數據中心工作人員將會立即得到通知。
實時監控設備使企業能夠規劃其資產的生命週期,包括在設備過時之前移除或更換設備,並計劃切換,以最大限度地減少運營中斷和額外的人工成本。雖然新部署的設備功能更強大,效率更高,但並不一定能夠降低功耗,因此瞭解數據中心設備(無論新舊)如何影響電源和冷卻需求至關重要。在設備方面,另一個節省成本的重要措施是實時監控能夠使企業在損壞之前識別那些處於危險中的資產,以及可能發生的更嚴重問題(例如停機,丟失數據以及需要維修或更換設備)。停機對於企業來說是一項重大的成本,在某些情況下可能導致數據丟失或客戶流失。及時更換設備並應對潛在威脅是防止意外停機的關鍵方法。
許多數據中心管理人員並不瞭解其當前設備的效率或利用率,這在需要擴展時可能會出現問題。企業購買新設備以擴大產能,增加空間使用,設備和電力成本,而不是優化現有設備,並從投資中獲得最大價值。對現有設備和利用率的實時監控和理解減少或消除了這種超支。
實時監控至關重要,因爲它可以自動執行笨拙,耗時,通常不準確且快速過時的人工實施過程。它使企業能夠監控數據中心資產的確切位置,生命週期,性能,維護歷史和狀況,並獲得對影響運營的環境條件的重要洞察力。
其最終結果是節省成本,而這取決於降低能耗,降低存儲成本,更有效地利用能源,更有效地提高員工生產,以及在發生或之前識別和解決代價高昂的潛在問題的能力。
無論組織是在內部部署的數據中心管理數據,還是在不同城市,州或國家的不同建築物中管理數據,還是使用私有云或託管數據中心來降低成本,他們必須管理自己的數據中心,以確保他們在成本和資源方面有效運行。
組織的大部分業務都駐留在數據中心。爲了保護企業業務及其投資,必須對數據中心資產進行實時,持續的檢查和分析,以查看詳細信息和全局信息。而數據中心的成本節約可以爲企業帶來真正的競爭優勢。

保持成本,跟蹤資產和實現此優化的最佳實踐是在整個生命週期內實時監控設備,從部署到運營和維護,再到資產退役的那一刻。這可以控制成本,確保設備和其他資源的最佳性能,並且對於許多企業而言,遵守PCI數據安全性,健康保險流通與責任法案(HIPAA)或服務組織控制(SOC)等相關標準以確保安全性和數據的可用性。
受實時監控影響的典型數據中心成本包括:
•用於溫度和溼度控制的能源
•購買新設備以替換過時的設備
•購買新設備以更換因泄漏,故障或環境條件變化而損壞的設備
•非工作設備造成的停機時間
•購買新設備以在現有設備未經優化和充分利用時擴大容量
•實時監控使數據中心管理人員能夠理解每個問題以及它們如何影響運營和成本
作爲運營成本的最主要的部門,能源使用是組織可以優化來降低成本的關鍵領域。監控能耗和風扇速度等事項將有助於數據中心管理人員瞭解數據中心如何運作以及在何處進行調整。有關環境條件的實時更新可以在潛在問題升級之前進行識別,例如火災,設備過熱或冷卻水或冷卻液泄漏,並且不再需要過度冷卻數據中心,以免因設備過熱而造成損壞。通過實時傳感器跟蹤溫度和設備性能,如果溫度發生劇烈變化,數據中心工作人員將會立即得到通知。
實時監控設備使企業能夠規劃其資產的生命週期,包括在設備過時之前移除或更換設備,並計劃切換,以最大限度地減少運營中斷和額外的人工成本。雖然新部署的設備功能更強大,效率更高,但並不一定能夠降低功耗,因此瞭解數據中心設備(無論新舊)如何影響電源和冷卻需求至關重要。在設備方面,另一個節省成本的重要措施是實時監控能夠使企業在損壞之前識別那些處於危險中的資產,以及可能發生的更嚴重問題(例如停機,丟失數據以及需要維修或更換設備)。停機對於企業來說是一項重大的成本,在某些情況下可能導致數據丟失或客戶流失。及時更換設備並應對潛在威脅是防止意外停機的關鍵方法。
許多數據中心管理人員並不瞭解其當前設備的效率或利用率,這在需要擴展時可能會出現問題。企業購買新設備以擴大產能,增加空間使用,設備和電力成本,而不是優化現有設備,並從投資中獲得最大價值。對現有設備和利用率的實時監控和理解減少或消除了這種超支。
實時監控至關重要,因爲它可以自動執行笨拙,耗時,通常不準確且快速過時的人工實施過程。它使企業能夠監控數據中心資產的確切位置,生命週期,性能,維護歷史和狀況,並獲得對影響運營的環境條件的重要洞察力。
其最終結果是節省成本,而這取決於降低能耗,降低存儲成本,更有效地利用能源,更有效地提高員工生產,以及在發生或之前識別和解決代價高昂的潛在問題的能力。
無論組織是在內部部署的數據中心管理數據,還是在不同城市,州或國家的不同建築物中管理數據,還是使用私有云或託管數據中心來降低成本,他們必須管理自己的數據中心,以確保他們在成本和資源方面有效運行。
組織的大部分業務都駐留在數據中心。爲了保護企業業務及其投資,必須對數據中心資產進行實時,持續的檢查和分析,以查看詳細信息和全局信息。而數據中心的成本節約可以爲企業帶來真正的競爭優勢。

With datacenter migration, many organizations and companies have adopted virtualization priority policies that require all new applications to run in a virtual environment.However, migrating traditional legacy applications to a virtualized environment is quite another matter.
While the industry is increasingly focused on technology and the benefits IT can bring to the organization's bottom line, a recent Spiceworks survey finds that spending on IT budgets has stalled.Companies are also failing to keep up with the demand for new technology.As a result of these trends, enterprise IT staff are constantly being asked to complete more tasks with less money.
The inevitable consequence of flat corporate IT budgets and reduced corporate IT staffing is that the priorities of projects involving traditional applications are reduced.Indeed, newly developed applications can run on virtual servers and are governed by virtualization priorities.But, as in, "if it's not broken, don't get busy trying to fix it."As the saying goes: because businesses lack the costs of pushing devices to achieve natural obsolescence (EOL), they often don't have the IT budget to move applications from traditional physical servers to virtual servers.
For most enterprise organizations, regardless of their size, mixed IT environments containing virtual and physical servers are now being processed.This is not an ideal situation in any case.The mixed environment complicates almost every aspect of server management.It reduces the productivity of administrators, increases the cost of management tools, decentralizes knowledge of management tools among administrators, and can lead to a significant reduction in application availability and data integrity.
Why deploy virtualization?
So why is there so much debate around deployment of virtualization?Why are IT organizations so obsessed with this technology?
1. Reduce capital expenditure
Deploying virtualization enables physical servers to host multiple virtual servers.It also provides the ability to easily migrate virtual servers between different physical servers to balance the need for resources.Physical servers running virtualized software can often run at more than 80 percent of their rated capacity.Integrating business applications into a single physical server, each of which has its own separate operating environment, can significantly reduce the number of physical servers in an enterprise data center.With fewer physical servers, IT organizations can further reduce capital expenditure, freeing up that money for other business divisions of the organization and increasing revenues.There are, of course, many other benefits.
2. Reduce operating expenses
Reducing the number of physical servers in data centers would also help corporate data centers save energy costs, and carbon emissions are an important consideration for corporate data center investors and shareholders to track metrics of concern.Also, it enables data centers to host more applications, which is a key factor in making data center real estate more valuable.
From a management perspective, it is much easier to configure and split virtual machines.If an application needs a new server, the administrator can configure the virtual machine much faster than the physical server.This typically reduces configuration time from weeks to hours or less, helping to develop applications quickly.
Virtual machines are also easier to manage than physical objects.A virtualized administrator can manage more machines instead of just a few physical devices.This helps improve the efficiency of administrators and alleviates the staffing problem in enterprise data centers.
Disadvantages of virtualization
Of course, virtualization technology also has its disadvantages.Not all business applications are suitable for running on a virtual server.While deploying virtualization can help businesses save money, the technology can also lead to increased spending in some other areas.As with many technologies, the rash use of the technology without sufficient knowledge of it may exacerbate problems that were originally intended to be solved with it.
Not everything can be virtualized
Virtualization is not the best choice for all applications.Applications that are very performance-sensitive may not be appropriate.These applications are unlikely to tolerate sharing physical resources with other applications, and the overhead of running a hypervisor on the same hardware may not be welcomed by enterprise customers.
There are various applications that require their servers to have physical attachments, and such applications often have unique drivers.Although virtual hypervisor software attracts most application use cases, it does not usually support these unusual applications.
Not all applications can be virtualized.For some applications, there may be license agreements that prevent virtualization.It can also be complex for some other applications.
Many enterprise organizations use old, traditional applications that are critical to the enterprise's key business, but have become so complex over many years of upgrades and changes that it is too risky to move them to a virtual platform.
2. Cost increase
The cost of the associated components may affect the deployment of virtualization technologies by enterprise customers.Although virtualization can help companies reduce operating costs over the long term, there are upfront investment costs associated with implementing the technology.
The host server used to run each virtual manager must be able to support the performance requirements of all virtual servers.These servers may cost more than the physical servers they replace.
Given the variety of tools available on the market today, many of which are provided by virtual hypervisor vendors, server and network administrators for enterprise customers must be trained in virtualization technology.
3. Server spread
Ironically, the problem of server sprawl that virtualization promises to solve is actually often exacerbated by the deployment of virtual machines.
When an enterprise data center deploys a server without fully understanding the impact it will have, server sprawl becomes an important issue for the data center.This often results in a data center filled with server hardware that needs to consume valuable energy and footprint over time, but is not fully utilized.
Server virtualization solves this problem.Integrating many physical servers on a single virtual server can ease energy and space constraints.However, the ease of configuring a virtual machine can lead to excessive server sprawl.
4. Single point of failure
Finally, an obvious drawback to server virtualization is that hosting multiple virtual servers on one piece of hardware has the potential to cause a single point of failure.If the physical server running the hypervisor fails, all applications running on the hypervisor managed virtual machine will be unavailable.
New data protection methods are needed to ensure data availability and data integrity in a virtual server environment.While many virtualized deployments rely on existing data protection technologies, the assumption is that a solution that works for a physical server will work for the virtual server as well, but in fact, the virtualization infrastructure presents a corresponding challenge.This is not just because the operational environments of enterprise data centers are unlikely to be entirely virtualized.
