本發明(ming)涉(she)及信息(xi)處理技術領域，尤(you)其涉(she)及一(yi)種跨數據(ju)中(zhong)心的(de)數據(ju)計(ji)算方法及系統。

背景技術：

云存儲系統需要(yao)記錄某個(ge)時(shi)間(jian)(jian)點(dian)上每個(ge)用(yong)(yong)(yong)戶(hu)(hu)的實(shi)際使用(yong)(yong)(yong)容(rong)量(liang)和配額(e)容(rong)量(liang)，對用(yong)(yong)(yong)戶(hu)(hu)的存儲空間(jian)(jian)的配額(e)進行檢查，保證使用(yong)(yong)(yong)容(rong)量(liang)達到配額(e)后(hou)不(bu)能繼續占(zhan)用(yong)(yong)(yong)更多存儲空間(jian)(jian)。如當已(yi)使用(yong)(yong)(yong)空間(jian)(jian)超過配額(e)容(rong)量(liang)時(shi)，系統應(ying)(ying)該禁止(zhi)用(yong)(yong)(yong)戶(hu)(hu)執行創建(jian)(jian)操作。當用(yong)(yong)(yong)戶(hu)(hu)刪(shan)除部分內(nei)容(rong)后(hou)，使用(yong)(yong)(yong)空間(jian)(jian)小(xiao)于配額(e)容(rong)量(liang)時(shi)，系統應(ying)(ying)該恢復(fu)用(yong)(yong)(yong)戶(hu)(hu)執行創建(jian)(jian)操作。

而云(yun)(yun)(yun)存儲(chu)(chu)系(xi)統(tong)分布在(zai)多個數據中(zhong)心(xin)中(zhong)，同一用(yong)戶的(de)(de)(de)不同請求經過不同的(de)(de)(de)接(jie)入(ru)節(jie)點連(lian)入(ru)云(yun)(yun)(yun)存儲(chu)(chu)系(xi)統(tong)。在(zai)付費的(de)(de)(de)云(yun)(yun)(yun)存儲(chu)(chu)系(xi)統(tong)中(zhong)，需(xu)要統(tong)計(ji)每一用(yong)戶的(de)(de)(de)操(cao)作記(ji)(ji)錄，根(gen)據操(cao)作記(ji)(ji)錄進行收費。在(zai)現(xian)有技術中(zhong)在(zai)進行操(cao)作記(ji)(ji)錄的(de)(de)(de)統(tong)計(ji)時，采用(yong)集中(zhong)的(de)(de)(de)單點設(she)備(bei)實時進行統(tong)計(ji)，這種方式的(de)(de)(de)問題在(zai)于會因為(wei)單點設(she)備(bei)的(de)(de)(de)設(she)備(bei)能力導(dao)致(zhi)統(tong)計(ji)瓶(ping)頸，造成(cheng)延(yan)時大，若該(gai)單點設(she)備(bei)出現(xian)故障會導(dao)致(zhi)統(tong)計(ji)結(jie)果需(xu)要重新開始(shi)計(ji)算(suan)，故統(tong)計(ji)成(cheng)本很(hen)大。

技術實現要素：

如圖1所示，本實施(shi)例提供一種跨(kua)數據中心的數據計算方法，所述(shu)方法包括(kuo)：

步驟S110：共(gong)享集群接(jie)收按(an)照預(yu)設發送策略發送的統(tong)計信息；所(suo)述統(tong)計信息是(shi)基于至少兩個數據中(zhong)心訪問信息系統(tong)形成的操作記(ji)錄形成的；

步驟(zou)S120：接收統(tong)計服務器(qi)發送的統(tong)計請求；

步驟S130：根據所(suo)述統(tong)(tong)計(ji)請(qing)求(qiu)，統(tong)(tong)計(ji)存(cun)儲在所(suo)述共享集(ji)群內(nei)的統(tong)(tong)計(ji)信(xin)息，形成(cheng)統(tong)(tong)計(ji)結果；

步(bu)驟S140：將所述統計結果發送給統計服務(wu)器。

本(ben)實(shi)施例提供(gong)的(de)跨數(shu)據中(zhong)(zhong)心的(de)數(shu)據計算方法(fa)可應用(yong)于共(gong)享集群(qun)(qun)中(zhong)(zhong)，例如(ru)用(yong)來對云(yun)存(cun)儲系統(tong)的(de)用(yong)戶操作記錄的(de)統(tong)計。本(ben)實(shi)施例所述的(de)共(gong)享集群(qun)(qun)可包括一(yi)臺(tai)或一(yi)臺(tai)以上的(de)處理(li)設備。

在步驟S110中所(suo)(suo)述共(gong)享(xiang)集群接收按照預(yu)(yu)設發送(song)策(ce)略(lve)發送(song)的統(tong)計(ji)信息(xi)。這里的所(suo)(suo)述統(tong)計(ji)信息(xi)可(ke)為(wei)(wei)操(cao)作(zuo)(zuo)記(ji)(ji)錄(lu)(lu)。所(suo)(suo)述操(cao)作(zuo)(zuo)記(ji)(ji)錄(lu)(lu)可(ke)為(wei)(wei)最原始的統(tong)計(ji)信息(xi)。所(suo)(suo)述統(tong)計(ji)信息(xi)還可(ke)包(bao)括前一級共(gong)享(xiang)集群形成的統(tong)計(ji)結果。該操(cao)作(zuo)(zuo)記(ji)(ji)錄(lu)(lu)可(ke)為(wei)(wei)原始記(ji)(ji)錄(lu)(lu)在云存儲(chu)系統(tong)的接入(ru)設備(bei)中的操(cao)作(zuo)(zuo)記(ji)(ji)錄(lu)(lu)。這里的預(yu)(yu)設發送(song)策(ce)略(lve)可(ke)包(bao)括按預(yu)(yu)設時間間隔發送(song)的操(cao)作(zuo)(zuo)記(ji)(ji)錄(lu)(lu)，也可(ke)以按照當所(suo)(suo)述操(cao)作(zuo)(zuo)記(ji)(ji)錄(lu)(lu)的更新量(liang)達到(dao)預(yu)(yu)設數(shu)據量(liang)時操(cao)作(zuo)(zuo)記(ji)(ji)錄(lu)(lu)。

在步驟S120所述(shu)共享集群將(jiang)會接收統(tong)(tong)計(ji)(ji)(ji)(ji)服務(wu)器發送(song)(song)的統(tong)(tong)計(ji)(ji)(ji)(ji)請求(qiu)，在步驟S130中將(jiang)在接收到統(tong)(tong)計(ji)(ji)(ji)(ji)請求(qiu)之后，統(tong)(tong)計(ji)(ji)(ji)(ji)所述(shu)操作記錄(lu)，形成統(tong)(tong)計(ji)(ji)(ji)(ji)結(jie)(jie)果(guo)；并在步驟S140中將(jiang)統(tong)(tong)計(ji)(ji)(ji)(ji)結(jie)(jie)果(guo)發送(song)(song)給服務(wu)器。在本實(shi)施例中所述(shu)統(tong)(tong)計(ji)(ji)(ji)(ji)結(jie)(jie)果(guo)可包(bao)括用(yong)戶在當前統(tong)(tong)計(ji)(ji)(ji)(ji)時間(jian)(jian)端(duan)內使用(yong)的存(cun)儲空(kong)間(jian)(jian)容量(liang)(liang)、訪(fang)問請求(qiu)數(shu)以及(ji)數(shu)據交(jiao)互流(liu)量(liang)(liang)等數(shu)據。

首(shou)先(xian)在本實施例中，所述(shu)統(tong)(tong)計(ji)(ji)服務器不直接(jie)參數統(tong)(tong)計(ji)(ji)，而(er)(er)是由(you)存儲操作(zuo)記(ji)錄的一個(ge)共享(xiang)(xiang)集(ji)群進行統(tong)(tong)計(ji)(ji)。共享(xiang)(xiang)集(ji)群內(nei)包括多個(ge)設(she)備，多個(ge)設(she)備同時(shi)參與統(tong)(tong)計(ji)(ji)，可以(yi)減(jian)少延時(shi)。由(you)于(yu)共享(xiang)(xiang)集(ji)群內(nei)多個(ge)設(she)備同時(shi)出(chu)現故障的概(gai)率低，從而(er)(er)相(xiang)對(dui)于(yu)有(you)統(tong)(tong)計(ji)(ji)服務器單獨統(tong)(tong)計(ji)(ji)，會因為故障導致的需(xu)要重頭重新統(tong)(tong)計(ji)(ji)的概(gai)率低，從而(er)(er)提高統(tong)(tong)計(ji)(ji)的安(an)全性(xing)。

作(zuo)為本實施例(li)的進一步改進，所述共(gong)享(xiang)集群(qun)包括區(qu)域共(gong)享(xiang)集群(qun)；所述統計服務器包括區(qu)域統計服務器；

所(suo)述(shu)步(bu)驟S110可包(bao)括：所(suo)述(shu)區域共享(xiang)集群按(an)照所(suo)述(shu)第一預設時間間隔從所(suo)述(shu)接(jie)入節點接(jie)收操作記(ji)錄；

所述步驟(zou)S140可包括：將所述區(qu)域統(tong)(tong)計(ji)結果發送給區(qu)域統(tong)(tong)計(ji)服務器。

在本實施(shi)例中所(suo)(suo)述(shu)(shu)(shu)接入設(she)(she)備會將(jiang)本地數據庫中存儲(chu)所(suo)(suo)述(shu)(shu)(shu)操(cao)作記錄(lu)。按照所(suo)(suo)述(shu)(shu)(shu)第(di)一預(yu)(yu)(yu)設(she)(she)時間(jian)(jian)(jian)(jian)(jian)間(jian)(jian)(jian)(jian)(jian)隔(ge)上報所(suo)(suo)述(shu)(shu)(shu)區(qu)域共(gong)享集群。本實施(shi)例所(suo)(suo)述(shu)(shu)(shu)第(di)一時間(jian)(jian)(jian)(jian)(jian)間(jian)(jian)(jian)(jian)(jian)隔(ge)可(ke)為預(yu)(yu)(yu)先設(she)(she)置的(de)(de)(de)時間(jian)(jian)(jian)(jian)(jian)間(jian)(jian)(jian)(jian)(jian)隔(ge)。任(ren)意(yi)兩(liang)個所(suo)(suo)述(shu)(shu)(shu)第(di)一預(yu)(yu)(yu)設(she)(she)時間(jian)(jian)(jian)(jian)(jian)間(jian)(jian)(jian)(jian)(jian)隔(ge)可(ke)都相等，這樣的(de)(de)(de)話，所(suo)(suo)述(shu)(shu)(shu)區(qu)域共(gong)享集群將(jiang)按周期接收所(suo)(suo)述(shu)(shu)(shu)操(cao)作記錄(lu)。但是，兩(liang)個所(suo)(suo)述(shu)(shu)(shu)第(di)一預(yu)(yu)(yu)設(she)(she)時間(jian)(jian)(jian)(jian)(jian)間(jian)(jian)(jian)(jian)(jian)隔(ge)也(ye)可(ke)以(yi)不相等。例如，晚(wan)間(jian)(jian)(jian)(jian)(jian)用戶訪問(wen)(wen)云(yun)存儲(chu)系(xi)統(tong)的(de)(de)(de)訪問(wen)(wen)頻(pin)次相對于白天的(de)(de)(de)訪問(wen)(wen)頻(pin)次叫低。為了實現更好的(de)(de)(de)統(tong)計(ji)，在晚(wan)間(jian)(jian)(jian)(jian)(jian)的(de)(de)(de)所(suo)(suo)述(shu)(shu)(shu)第(di)一時間(jian)(jian)(jian)(jian)(jian)間(jian)(jian)(jian)(jian)(jian)隔(ge)可(ke)以(yi)大于在白天的(de)(de)(de)所(suo)(suo)述(shu)(shu)(shu)第(di)一時間(jian)(jian)(jian)(jian)(jian)間(jian)(jian)(jian)(jian)(jian)隔(ge)。

所述(shu)區域(yu)共(gong)享集群接(jie)收到所述(shu)統計記(ji)錄之后(hou)，將(jiang)存儲所述(shu)統計記(ji)錄。這樣的(de)話(hua)，即(ji)便區域(yu)共(gong)享集群出(chu)現(xian)故障(zhang)，丟失部分數(shu)據，還可以從接(jie)入設備中重新提取，從而保證(zheng)數(shu)據的(de)高(gao)安全性(xing)。

所述區(qu)域共(gong)享(xiang)集(ji)(ji)(ji)群接收(shou)區(qu)域統(tong)(tong)計(ji)(ji)(ji)(ji)服務器發送(song)的(de)(de)統(tong)(tong)計(ji)(ji)(ji)(ji)請求，這(zhe)樣(yang)區(qu)域共(gong)享(xiang)集(ji)(ji)(ji)群就分區(qu)域進(jin)行了統(tong)(tong)計(ji)(ji)(ji)(ji)。顯然一(yi)(yi)個云(yun)存(cun)儲系(xi)統(tong)(tong)中可能(neng)存(cun)在多個云(yun)存(cun)儲區(qu)域；每個云(yun)存(cun)儲區(qu)域都(dou)可對應設置一(yi)(yi)個區(qu)域共(gong)享(xiang)集(ji)(ji)(ji)群，這(zhe)樣(yang)的(de)(de)話，即便一(yi)(yi)個區(qu)域共(gong)享(xiang)集(ji)(ji)(ji)群出現故障，導致該區(qu)域內的(de)(de)統(tong)(tong)計(ji)(ji)(ji)(ji)結果(guo)不(bu)(bu)能(neng)及(ji)時(shi)提(ti)供，也不(bu)(bu)會(hui)干擾到其他(ta)區(qu)域內的(de)(de)統(tong)(tong)計(ji)(ji)(ji)(ji)結果(guo)，從而重新統(tong)(tong)計(ji)(ji)(ji)(ji)的(de)(de)數(shu)據量小，對于整個系(xi)統(tong)(tong)內整個統(tong)(tong)計(ji)(ji)(ji)(ji)結果(guo)的(de)(de)處(chu)理而言，依然能(neng)夠減少(shao)延(yan)時(shi)，保(bao)證統(tong)(tong)計(ji)(ji)(ji)(ji)結果(guo)的(de)(de)安全(quan)性。

作為本實施例的進(jin)一(yi)步改進(jin)，所(suo)(suo)述共(gong)享(xiang)集群還(huan)包括(kuo)(kuo)系(xi)統共(gong)享(xiang)集群；所(suo)(suo)述統計(ji)服(fu)務器(qi)還(huan)包括(kuo)(kuo)系(xi)統統計(ji)服(fu)務器(qi)。

所(suo)(suo)述(shu)步驟S110還包括：所(suo)(suo)述(shu)系統(tong)共(gong)享集(ji)群(qun)接收所(suo)(suo)述(shu)區(qu)(qu)域共(gong)享集(ji)群(qun)形成區(qu)(qu)域統(tong)計結果。這里的區(qu)(qu)域統(tong)計結果即為(wei)前(qian)述(shu)所(suo)(suo)述(shu)的統(tong)計信息。

所(suo)述(shu)(shu)步驟S120還(huan)包(bao)括(kuo)：所(suo)述(shu)(shu)系(xi)(xi)統(tong)共享集群接收所(suo)述(shu)(shu)系(xi)(xi)統(tong)統(tong)計(ji)服務器發送的系(xi)(xi)統(tong)統(tong)計(ji)請(qing)求；

所述(shu)(shu)步驟S130可包(bao)括：所述(shu)(shu)系(xi)統(tong)(tong)(tong)共享(xiang)集群根據所述(shu)(shu)系(xi)統(tong)(tong)(tong)統(tong)(tong)(tong)計(ji)請求(qiu)，統(tong)(tong)(tong)計(ji)存(cun)儲(chu)在(zai)所述(shu)(shu)系(xi)統(tong)(tong)(tong)共享(xiang)集群內的操作記錄，形成系(xi)統(tong)(tong)(tong)統(tong)(tong)(tong)計(ji)結果。

在(zai)本實施(shi)例(li)中所(suo)述(shu)(shu)(shu)統計(ji)服務(wu)器(qi)(qi)也(ye)分為(wei)兩(liang)級(ji)(ji)，一(yi)(yi)級(ji)(ji)為(wei)區(qu)域統計(ji)服務(wu)器(qi)(qi)，另一(yi)(yi)級(ji)(ji)為(wei)系統統計(ji)服務(wu)器(qi)(qi)。所(suo)述(shu)(shu)(shu)共(gong)享集(ji)群(qun)也(ye)分為(wei)兩(liang)級(ji)(ji)，一(yi)(yi)級(ji)(ji)為(wei)區(qu)域共(gong)性集(ji)群(qun)，另一(yi)(yi)級(ji)(ji)為(wei)系統共(gong)享集(ji)群(qun)。在(zai)本實施(shi)例(li)的框架內，所(suo)述(shu)(shu)(shu)共(gong)享集(ji)群(qun)不局限于兩(liang)級(ji)(ji)，還(huan)可以(yi)分為(wei)三級(ji)(ji)、四級(ji)(ji)或(huo)四級(ji)(ji)以(yi)上(shang)的。所(suo)述(shu)(shu)(shu)統計(ji)服務(wu)器(qi)(qi)也(ye)可以(yi)分為(wei)三級(ji)(ji)、四級(ji)(ji)或(huo)四級(ji)(ji)以(yi)上(shang)的統計(ji)服務(wu)器(qi)(qi)。

在本(ben)實(shi)(shi)施(shi)例(li)中所(suo)(suo)(suo)(suo)述(shu)(shu)(shu)第(di)(di)二時(shi)間(jian)(jian)間(jian)(jian)隔(ge)可(ke)以等于所(suo)(suo)(suo)(suo)述(shu)(shu)(shu)第(di)(di)一(yi)時(shi)間(jian)(jian)間(jian)(jian)隔(ge)，也(ye)可(ke)以不(bu)(bu)等于所(suo)(suo)(suo)(suo)述(shu)(shu)(shu)第(di)(di)一(yi)時(shi)間(jian)(jian)間(jian)(jian)隔(ge)。當然任意兩(liang)個所(suo)(suo)(suo)(suo)述(shu)(shu)(shu)第(di)(di)一(yi)時(shi)間(jian)(jian)間(jian)(jian)隔(ge)可(ke)以相等，也(ye)可(ke)以不(bu)(bu)相等。在本(ben)實(shi)(shi)施(shi)例(li)中所(suo)(suo)(suo)(suo)述(shu)(shu)(shu)系(xi)統(tong)共(gong)享集(ji)群(qun)將從(cong)統(tong)計(ji)(ji)(ji)服(fu)(fu)務器(qi)接(jie)收(shou)已(yi)成(cheng)功統(tong)計(ji)(ji)(ji)的操作記錄。本(ben)實(shi)(shi)施(shi)例(li)中所(suo)(suo)(suo)(suo)述(shu)(shu)(shu)系(xi)統(tong)共(gong)享集(ji)群(qun)接(jie)收(shou)區(qu)(qu)(qu)域(yu)(yu)(yu)共(gong)享集(ji)群(qun)統(tong)計(ji)(ji)(ji)形(xing)成(cheng)的區(qu)(qu)(qu)域(yu)(yu)(yu)統(tong)計(ji)(ji)(ji)結果，對各(ge)個區(qu)(qu)(qu)域(yu)(yu)(yu)的區(qu)(qu)(qu)域(yu)(yu)(yu)統(tong)計(ji)(ji)(ji)結果進行統(tong)計(ji)(ji)(ji)處理，得到系(xi)統(tong)統(tong)計(ji)(ji)(ji)結果。在本(ben)實(shi)(shi)施(shi)例(li)中所(suo)(suo)(suo)(suo)述(shu)(shu)(shu)系(xi)統(tong)共(gong)享集(ji)群(qun)可(ke)以直接(jie)從(cong)所(suo)(suo)(suo)(suo)述(shu)(shu)(shu)區(qu)(qu)(qu)域(yu)(yu)(yu)共(gong)享集(ji)群(qun)接(jie)收(shou)所(suo)(suo)(suo)(suo)述(shu)(shu)(shu)區(qu)(qu)(qu)域(yu)(yu)(yu)統(tong)計(ji)(ji)(ji)結果，也(ye)可(ke)以通過所(suo)(suo)(suo)(suo)述(shu)(shu)(shu)區(qu)(qu)(qu)域(yu)(yu)(yu)統(tong)計(ji)(ji)(ji)服(fu)(fu)務器(qi)來(lai)接(jie)收(shou)所(suo)(suo)(suo)(suo)述(shu)(shu)(shu)區(qu)(qu)(qu)域(yu)(yu)(yu)統(tong)計(ji)(ji)(ji)結果。

如圖2所示，在(zai)本實施例中所述方(fang)法還包(bao)括：

步(bu)驟S131：所(suo)述(shu)區域(yu)共享集群對所(suo)述(shu)操作記錄進行匯(hui)總，形成區域(yu)匯(hui)總文件(jian)；所(suo)述(shu)區域(yu)匯(hui)總文件(jian)用于區域(yu)級備(bei)份；

所述(shu)系統共(gong)享(xiang)集群對所述(shu)區域匯總(zong)(zong)文(wen)件(jian)進行匯總(zong)(zong)，形成系統匯總(zong)(zong)文(wen)件(jian)；所述(shu)系統匯總(zong)(zong)文(wen)件(jian)用于系統級備份(fen)。

多(duo)個(ge)操作記錄匯(hui)(hui)(hui)總(zong)文(wen)(wen)(wen)(wen)件可形成(cheng)區域(yu)匯(hui)(hui)(hui)總(zong)文(wen)(wen)(wen)(wen)集(ji)。所(suo)述(shu)區域(yu)匯(hui)(hui)(hui)總(zong)文(wen)(wen)(wen)(wen)件還將作為下一(yi)(yi)級(ji)共(gong)享集(ji)群(qun)進(jin)行(xing)(xing)匯(hui)(hui)(hui)總(zong)的統(tong)計(ji)(ji)(ji)信(xin)(xin)息(xi)。所(suo)述(shu)系(xi)統(tong)共(gong)享集(ji)群(qun)在接收(shou)所(suo)述(shu)區域(yu)統(tong)計(ji)(ji)(ji)結(jie)果(guo)的同時，可一(yi)(yi)同從區域(yu)共(gong)享集(ji)群(qun)或區域(yu)統(tong)計(ji)(ji)(ji)服(fu)務器接收(shou)所(suo)述(shu)區域(yu)匯(hui)(hui)(hui)總(zong)文(wen)(wen)(wen)(wen)件，并對所(suo)述(shu)區域(yu)匯(hui)(hui)(hui)總(zong)文(wen)(wen)(wen)(wen)件進(jin)行(xing)(xing)匯(hui)(hui)(hui)總(zong)形成(cheng)系(xi)統(tong)匯(hui)(hui)(hui)總(zong)文(wen)(wen)(wen)(wen)件。本實施例所(suo)述(shu)匯(hui)(hui)(hui)總(zong)文(wen)(wen)(wen)(wen)件是進(jin)行(xing)(xing)了信(xin)(xin)息(xi)匯(hui)(hui)(hui)總(zong)，排除了錯誤(wu)統(tong)計(ji)(ji)(ji)信(xin)(xin)息(xi)和(he)(he)冗余統(tong)計(ji)(ji)(ji)信(xin)(xin)息(xi)，進(jin)行(xing)(xing)了壓縮等(deng)處理(li)的可用(yong)于(yu)對統(tong)計(ji)(ji)(ji)信(xin)(xin)息(xi)進(jin)行(xing)(xing)備份的信(xin)(xin)息(xi)。在本實施例中，通過(guo)所(suo)述(shu)匯(hui)(hui)(hui)總(zong)文(wen)(wen)(wen)(wen)件的生成(cheng)和(he)(he)傳(chuan)輸(shu)，可以(yi)在共(gong)享集(ji)群(qun)和(he)(he)統(tong)計(ji)(ji)(ji)服(fu)務器內進(jin)行(xing)(xing)統(tong)計(ji)(ji)(ji)信(xin)(xin)息(xi)的備份，這樣即(ji)便共(gong)享集(ji)群(qun)和(he)(he)/或統(tong)計(ji)(ji)(ji)服(fu)務器中的部分設備出現故(gu)障(zhang)，也不會導(dao)致所(suo)有(you)數據的丟失，從而(er)增加了數據的安全(quan)性(xing)。

在(zai)具(ju)體的(de)實現(xian)過程中，所述匯總(zong)文件(jian)可(ke)將(jiang)與統計(ji)結(jie)果一通(tong)發送給統計(ji)服(fu)務器。

作為(wei)本實施例的進(jin)一步改進(jin)，如(ru)圖3所示，所述方法還包括：

步驟S132:

在形成(cheng)所(suo)(suo)述(shu)區(qu)域(yu)統(tong)計(ji)(ji)(ji)(ji)結果時，所(suo)(suo)述(shu)區(qu)域(yu)共(gong)享集群還生(sheng)成(cheng)區(qu)域(yu)成(cheng)功(gong)統(tong)計(ji)(ji)(ji)(ji)記(ji)錄(lu)(lu)信息(xi)；所(suo)(suo)述(shu)區(qu)域(yu)成(cheng)功(gong)統(tong)計(ji)(ji)(ji)(ji)記(ji)錄(lu)(lu)信息(xi)用于指示(shi)所(suo)(suo)述(shu)區(qu)域(yu)共(gong)享集群已成(cheng)功(gong)統(tong)計(ji)(ji)(ji)(ji)的操作記(ji)錄(lu)(lu)；

在(zai)形成(cheng)(cheng)所(suo)述(shu)系統(tong)(tong)統(tong)(tong)計結果(guo)時，所(suo)述(shu)系統(tong)(tong)共(gong)享集(ji)(ji)群還(huan)生(sheng)成(cheng)(cheng)系統(tong)(tong)成(cheng)(cheng)功(gong)(gong)統(tong)(tong)計記錄信息；所(suo)述(shu)系統(tong)(tong)級成(cheng)(cheng)功(gong)(gong)統(tong)(tong)計信息用于指示所(suo)述(shu)系統(tong)(tong)共(gong)享集(ji)(ji)群已成(cheng)(cheng)功(gong)(gong)統(tong)(tong)計的區域級統(tong)(tong)計結果(guo)。

在(zai)本實施例還將生成功統(tong)計(ji)(ji)(ji)記(ji)錄(lu)信息，并按區(qu)域和系統(tong)進(jin)(jin)行(xing)生成成功統(tong)計(ji)(ji)(ji)記(ji)錄(lu)信息，哪(na)些(xie)統(tong)計(ji)(ji)(ji)信息還進(jin)(jin)一步待(dai)統(tong)計(ji)(ji)(ji)。若設備出現故障(zhang)，在(zai)進(jin)(jin)行(xing)故障(zhang)恢復(fu)時，可以根據所述成功統(tong)計(ji)(ji)(ji)記(ji)錄(lu)信息，可以快速確定從哪(na)開始進(jin)(jin)行(xing)統(tong)計(ji)(ji)(ji)。

例如，所(suo)述區域共享集群和所(suo)述系統(tong)(tong)集群按照周期進行(xing)統(tong)(tong)計(ji)，則(ze)所(suo)述成(cheng)功(gong) 統(tong)(tong)計(ji)記(ji)錄信息可記(ji)錄目前(qian)已經(jing)完成(cheng)截止到(dao)哪個(ge)時間周期的成(cheng)功(gong)統(tong)(tong)計(ji)。

在本實施例中(zhong)還(huan)可以將所述成功統(tong)計(ji)記錄信息由(you)共(gong)享集群發送(song)給統(tong)計(ji)服(fu)(fu)務器，方便(bian)統(tong)計(ji)服(fu)(fu)務器備份及后續查詢。

以下結(jie)合人任(ren)意(yi)實施例提供一個具(ju)體示(shi)例：

如圖(tu)4所示(shi)，在本示(shi)例中(zhong)(zhong)，假設有(you)多(duo)個數(shu)(shu)據中(zhong)(zhong)心(xin)D1，D2…Dm；數(shu)(shu)據中(zhong)(zhong)心(xin)分布(bu)在不(bu)(bu)同的(de)城市或者洲際，數(shu)(shu)據中(zhong)(zhong)心(xin)之(zhi)間(jian)通(tong)過廣域網通(tong)信。數(shu)(shu)據中(zhong)(zhong)心(xin)D1中(zhong)(zhong)有(you)X個接入節點n1，n2，…nx；其中(zhong)(zhong)所述X為不(bu)(bu)小(xiao)于(yu)2的(de)整(zheng)數(shu)(shu)；所述x為不(bu)(bu)大于(yu)所述X的(de)正整(zheng)數(shu)(shu)。

同一個(ge)用戶(hu)的(de)不同請(qing)(qing)求(qiu)(qiu)(qiu)可能(neng)發(fa)給不同數(shu)據中(zhong)(zhong)(zhong)心(xin)的(de)不同接入節點(dian)(dian)(dian)進行(xing)處(chu)(chu)理。假設在(zai)2011年(nian)01月12日10點(dian)(dian)(dian)26分(fen)期(qi)間(jian)(jian)，接入節點(dian)(dian)(dian)1收到了(le)大量的(de)訪(fang)問(wen)請(qing)(qing)求(qiu)(qiu)(qiu)，其(qi)(qi)中(zhong)(zhong)(zhong)包括用戶(hu)u1發(fa)送過來的(de)創建10MB的(de)對(dui)(dui)象(xiang)/b1/o1請(qing)(qing)求(qiu)(qiu)(qiu)(PUT/b1/o1)、以及用戶(hu)u2發(fa)送過來的(de)創建20MB的(de)對(dui)(dui)象(xiang)/b2/o2請(qing)(qing)求(qiu)(qiu)(qiu)(PUT/b2/o2)。在(zai)接入節點(dian)(dian)(dian)1成(cheng)(cheng)(cheng)功(gong)處(chu)(chu)理完這兩個(ge)訪(fang)問(wen)請(qing)(qing)求(qiu)(qiu)(qiu)后，其(qi)(qi)會將(jiang)操作(zuo)(zuo)(zuo)記(ji)錄(lu)寫到本地的(de)操作(zuo)(zuo)(zuo)記(ji)錄(lu)文(wen)件中(zhong)(zhong)(zhong)，每個(ge)接入節點(dian)(dian)(dian)上(shang)的(de)操作(zuo)(zuo)(zuo)記(ji)錄(lu)文(wen)件每分(fen)鐘產(chan)(chan)生一個(ge)，如上(shang)述兩個(ge)請(qing)(qing)求(qiu)(qiu)(qiu)是(shi)接入節點(dian)(dian)(dian)1在(zai)2011年(nian)01月12日10點(dian)(dian)(dian)26分(fen)期(qi)間(jian)(jian)處(chu)(chu)理完的(de)，則產(chan)(chan)生的(de)操作(zuo)(zuo)(zuo)記(ji)錄(lu)文(wen)件名為(wei)n1-20110112-10-26，該(gai)文(wen)件中(zhong)(zhong)(zhong)記(ji)錄(lu)格式為(wei)<操作(zuo)(zuo)(zuo)記(ji)錄(lu)時間(jian)(jian)戳ts，操作(zuo)(zuo)(zuo)類型(xing)type(上(shang)傳1、下(xia)載(zai)2、刪除3等)，操作(zuo)(zuo)(zuo)是(shi)否處(chu)(chu)理成(cheng)(cheng)(cheng)功(gong)bool(成(cheng)(cheng)(cheng)功(gong)1、失敗0)，所(suo)屬數(shu)據中(zhong)(zhong)(zhong)心(xin)名Dname，用戶(hu)名User，桶(tong)名Bucket，對(dui)(dui)象(xiang)名Obj，大小size>，對(dui)(dui)于上(shang)述兩個(ge)請(qing)(qing)求(qiu)(qiu)(qiu)其(qi)(qi)在(zai)操作(zuo)(zuo)(zuo)記(ji)錄(lu)文(wen)件n1-20110112-10-26中(zhong)(zhong)(zhong)的(de)記(ji)錄(lu)條目為(wei)<20110112-10:26:36；1；1；D1；u1；b1；o1；10><20110112-10:26:46；1；1；D1；u2；b2；o2；20>。

接(jie)入節點130，用(yong)于在響應完用(yong)戶請求之(zhi)后，根(gen)據響應結(jie)果形(xing)成的操作記(ji)錄；所述操作記(ji)錄為所述統計信息(xi)之(zhi)一。

所(suo)(suo)述接入節點可為各種能(neng)夠(gou)電(dian)子設備(bei)，如(ru)云(yun)存儲系統的(de)云(yun)存儲設備(bei)，能(neng)夠(gou)用(yong)于(yu)接收(shou)用(yong)戶的(de)訪問(wen)請(qing)求(qiu)，響(xiang)應訪問(wen)請(qing)求(qiu)，根據響(xiang)應結果(guo)來形成所(suo)(suo)述操作(zuo)記(ji)錄。所(suo)(suo)述操作(zuo)記(ji)錄可包括在一定時間內的(de)訪問(wen)請(qing)求(qiu)數量(liang)、占用(yong)的(de)存儲空間及與用(yong)戶交(jiao)互的(de)數據流(liu)量(liang)等(deng)信息。

接入節(jie)點(dian)在處理完(wan)用(yong)戶(hu)訪問請(qing)求后(hou)，會先將操作(zuo)記錄(lu)寫到本地的操作(zuo)記錄(lu)文(wen)件(jian)中；在本地存儲到一(yi)(yi)定數量后(hou)一(yi)(yi)起發送給區域(yu)共(gong)享集群(qun)，相比于(yu)每(mei)處理一(yi)(yi) 個請(qing)求即(ji)在區域(yu)共(gong)享集群(qun)中記錄(lu)一(yi)(yi)次，大大提高寫效率、減少(shao)網絡開(kai)銷。

將每個接(jie)入節點的(de)操作(zuo)(zuo)記錄(lu)文件遷(qian)移到在區域(yu)共(gong)享集(ji)(ji)群中(zhong)集(ji)(ji)中(zhong)存(cun)(cun)儲、計(ji)(ji)算、并存(cun)(cun)放(fang)產生(sheng)輸出(chu)統計(ji)(ji)表，便于(yu)使用(yong)區域(yu)共(gong)享集(ji)(ji)群的(de)存(cun)(cun)儲資源的(de)數(shu)(shu)據(ju)(ju)冗(rong)余機制保證數(shu)(shu)據(ju)(ju)的(de)冗(rong)余存(cun)(cun)放(fang)不丟失(shi)(shi)、使用(yong)共(gong)享集(ji)(ji)群的(de)計(ji)(ji)算模(mo)塊(kuai)對整個數(shu)(shu)據(ju)(ju)中(zhong)心進(jin)行(xing)統計(ji)(ji)計(ji)(ji)算；相比存(cun)(cun)儲操作(zuo)(zuo)記錄(lu)文件和(he)輸出(chu)統計(ji)(ji)表在接(jie)入節點或區域(yu)統計(ji)(ji)服務(wu)器上(shang)提高(gao)了(le)計(ji)(ji)費(fei)的(de)正確性，因為接(jie)入節點或區域(yu)統計(ji)(ji)服務(wu)器的(de)單點故障會導致數(shu)(shu)據(ju)(ju)的(de)丟失(shi)(shi)、進(jin)而(er)導致計(ji)(ji)費(fei)的(de)不準確。

區域統(tong)(tong)(tong)計(ji)(ji)服務(wu)(wu)(wu)器每隔(ge)一定(ding)時間周期向(xiang)區域共享(xiang)集(ji)群自動發起統(tong)(tong)(tong)計(ji)(ji)計(ji)(ji)算(suan)請求(qiu)(qiu)，由區域共享(xiang)集(ji)群的(de)(de)(de)計(ji)(ji)算(suan)模塊對存(cun)儲在該集(ji)群上的(de)(de)(de)文件進行(xing)統(tong)(tong)(tong)計(ji)(ji)。區域統(tong)(tong)(tong)計(ji)(ji)服務(wu)(wu)(wu)器并不進行(xing)數據的(de)(de)(de)存(cun)儲和(he)計(ji)(ji)算(suan)，避免區域統(tong)(tong)(tong)計(ji)(ji)服務(wu)(wu)(wu)器的(de)(de)(de)單點故障會導(dao)致數據的(de)(de)(de)丟失、以及單臺機器計(ji)(ji)算(suan)效率低(di)的(de)(de)(de)問題。采用這種(zhong)結構，即使該區域統(tong)(tong)(tong)計(ji)(ji)服務(wu)(wu)(wu)器發生故障，再加入(ru)新(xin)的(de)(de)(de)區域統(tong)(tong)(tong)計(ji)(ji)服務(wu)(wu)(wu)器對區域共享(xiang)集(ji)群重新(xin)發起統(tong)(tong)(tong)計(ji)(ji)計(ji)(ji)算(suan)請求(qiu)(qiu)即可(ke)。

在(zai)(zai)區域共(gong)享集(ji)群(qun)中形成(cheng)成(cheng)功統(tong)計(ji)(ji)記(ji)錄信(xin)息，便于(yu)在(zai)(zai)區域統(tong)計(ji)(ji)服務器發生故(gu)障過段時間(jian)(jian)重(zhong)啟(qi)后(hou)、或者新(xin)的區域統(tong)計(ji)(ji)服務器加入后(hou)，向區域共(gong)享集(ji)群(qun)再次(ci)自動發起統(tong)計(ji)(ji)計(ji)(ji)算請求時，區域共(gong)享集(ji)群(qun)了解到(dao)目(mu)前的統(tong)計(ji)(ji)進展，便于(yu)從最(zui)近(jin)統(tong)計(ji)(ji)成(cheng)周期的下一(yi)個時間(jian)(jian)周期開始進行統(tong)計(ji)(ji)。采用(yong)這種結構避(bi)免數(shu)據的重(zhong)復統(tong)計(ji)(ji)，或者中途統(tong)計(ji)(ji)的丟失。
