【文章內(nèi)容簡介】 power distribution). Today 1 will show you around the server room and manding centre 供電系統(tǒng)是數(shù)據(jù)中心的核心保障，數(shù)據(jù)中心己建成了非常完備的供電設施。雙路市電IOKV輸入，高壓發(fā)電機組，雙路 UPS機組等，實現(xiàn) 7*24 小時不間斷供電。 UPS系統(tǒng)采用的是 Liebert 大容量機組， UPS 配備的電池容量可以支持滿負載 1 分分鐘供電。發(fā)電機在市電兩路都停電的情況下 15 秒內(nèi)自動啟動。整個數(shù)據(jù)中心供電系統(tǒng)的可靠 性達到五個九，即%。 The power supply system in the centre is very secure and plete: double municipal IOKV power input, standby generator group, double way UPS. The UPS system adopts the Liebert high capacity generator group. The UPS capacity can continuously provide the power to the full load system for 10 minutes. The generator could start in 15 seconds once the municipal power is interrupted. The dependability rate of the centre is %. 這里是數(shù)據(jù)中心的服務器機房（ Server farm)，共有兩層，每層 2021 平方米，每層可存放 200 臺大型服務器和 1800臺小服務器。服務器機房目前承載了公司主要的 IT 應用系統(tǒng)：如 ISC（包括 ERP、條碼系統(tǒng)等）、 IPDPDM（研發(fā)產(chǎn)品數(shù)據(jù)管埋）、 Notes、 Email、 Web、Card（卡證）、 HR（人力資源）等。 Here is the twostoried Server farm with an area of 20 thousand square feet each. It can acmodate 200 large servers and 1800 small servers. Presently, these servers support such applications as ISC (including ERP, bar code system etc.), 1PDPDM, Notes, Email, Web, Card and HR etc. They are highend Unix servers of IBM, HP and SUN, among which the SUN server 第 15 頁 共 52 頁 supports the bar code system, notes system, WEB and public dada base platform (the data base shared by a few of small systems) etc.。 IBM server supports such enterprise class systems as PDM, APS (the advanced planning system which is the production planning system extended form ISC。 HP supports ERP system respectively. 在企業(yè)存儲系統(tǒng)方面，我們采用 SAN 存儲區(qū)域網(wǎng)技術(shù)，實現(xiàn)了異構(gòu)環(huán)境下統(tǒng)一的存儲管理方案（不同服務器可以共享存儲）。相對以前獨立存儲（每個服務器自帶存儲）的好處是：一方面，存儲系統(tǒng)集中在一起后叫以提供 高性能、高可靠的存儲系統(tǒng)，存儲空間利用率得到提升，存儲空間分配更 加合理、靈活。另一方面是可以簡化管理。存儲系統(tǒng)采用HDS9980，目前存儲裸容量超過 l000TB,。 Huawei introduced the SAN (storage area work) technology to its enterprise storage system. SAN technology allows the servers to share all the data in the unified storage system. It differs from the independent storage system. We enjoy 2 benefits from SAN: the integration of independent storage systems provides a more reliable, flexible, reasonable, effective and unified system。 meanwhile, it simplifies the storage management. We adopt the HDS9980 in our storage system with a current capacity of overl000TB. 在企業(yè)備份系統(tǒng)方面，我們的數(shù)據(jù)備份全是在 SAN 的網(wǎng)絡（存儲區(qū)域網(wǎng)）中進行，不通過辦公局域網(wǎng)，不會影響用戶的使用，降低了我們局域網(wǎng)的壓力，我們也稱這種技術(shù)為LANFree（獨立光纖交換網(wǎng)技術(shù)）。目前我們備份系統(tǒng)的容量是 250TB。 We backups all the data in SAN through LANFree technology, which releases the pressure of our LAN, as it does not tax the office LAN. Currently, the total capacity of our backup system is 250TB. 除在坂田的數(shù)據(jù)中心外，在北研、上研、南研都有我們的備份系統(tǒng)，這些系統(tǒng)都是通過深圳的數(shù)據(jù)中心來進行集中管理的。 Apart from Bantian Data Processing Center, we have backup systems in many Ramp。D centers around China, eg : Beijing, shanghai and Nanjing. All theses backup systems are controlled by the Shenzhen Data Center. 在數(shù)據(jù)資產(chǎn)的容災保障方面，目前公司在北京也建立了一個異地的容災數(shù)據(jù)中心，通過多條 155M的帶寬，已實現(xiàn)對 ERP、財務、重要的 NOTES數(shù)據(jù)的在線備份。目前公司在災備 方面已實現(xiàn)了核心業(yè)務數(shù)據(jù)的及時恢復，我們最終的目標是建立一套完整的災難恢復的組織、策略、計劃和流程制度，在災難面前，實現(xiàn)業(yè)務的連續(xù)性。 In order to protect the data property, Huawei has established a data disaster recovery center in Beijing with several leased lines of 155M bandwidth . Presently, Huawei can have online data backup for ERP, finance, Notes system and the timely data recovery for the core operations. Our ultimate goal is to maintain the operation continuity in case of data disaster and to create a full set of disaster recovery policies respectively for anization, strategy, plan and process. 這是華為公司企業(yè)網(wǎng)的組網(wǎng)圖，華為企業(yè)網(wǎng)全網(wǎng)是由 4200 臺網(wǎng)絡設備，全網(wǎng)的網(wǎng)絡設備都是采用華為自主研制開發(fā)的品，覆蓋國內(nèi) 30 個辦事處、 300多個本地網(wǎng)，海外建立了 8第 16 頁 共 52 頁 個地區(qū)部和 85 個分支機構(gòu)。目前公司在海外的各分支機構(gòu)可以方便地訪問公司深圳總部的notes, , ERP 等服務器。 Huawei enterprise work consists of more than 4200 work devices.
