The cluster files should be stored on a shared drive . select z : and click next 集群文件應(yīng)存儲(chǔ)在共享磁盤中。選擇z盤。
Consequently , cluster file systems are often much less applicable when going between sites 因此,集群文件系統(tǒng)通常不太適合多個(gè)站點(diǎn)之間的情況。
Map network drives and create cluster file share resources for deployment and run - time files 映射網(wǎng)絡(luò)驅(qū)動(dòng)器,并為部署和實(shí)時(shí)文件創(chuàng)建群集文件共享資源。
As a key technology for solving the i / o problem of clusters , cluster file system is a very important research direction 機(jī)群文件系統(tǒng)作為解決機(jī)群i / o瓶頸的核心技術(shù),其研究具有重要的意義。
It mentions secure internet - wide clustered file systems on the first page of its web site - not a requirement likely to trouble first - time unix users 它在其網(wǎng)站的首頁(yè)上提到保護(hù)internet范圍的群集文件系統(tǒng)這對(duì)首次使用unix的用戶來說好像關(guān)系不大。
Typically , cluster file systems are suitable only for use within a single site because they re often sensitive to the degree of separation of the cluster nodes 通常情況下,集群文件系統(tǒng)都只適合一個(gè)站點(diǎn)使用,因?yàn)樗鼈兺ǔ6紝?duì)集群節(jié)點(diǎn)的隔離度非常敏感。
Bringing file sharing to a pure san configuration requires the implementation of a heterogeneous clustered file system . such a system is currently unavailable because its high degree of technical complexity makes it prohibitive from cost and performance standpoints 把文件共享帶給純的san配置需要實(shí)現(xiàn)一個(gè)異種機(jī)集群的文件系統(tǒng),目前尚無這樣的系統(tǒng),因?yàn)閺脑靸r(jià)和性能觀點(diǎn)看,高度的技術(shù)復(fù)雜性使之難以實(shí)現(xiàn)。
A group of metadata servers are used to provide multiple metadata paths . we study a few key issues for cluster file systems of such architecture , including metadata distribution issue , metadata consistency and fast recovery issue , and issues in regards to pb - scale cluster file system 針對(duì)這種結(jié)構(gòu)的機(jī)群文件系統(tǒng),我們研究了其中的幾個(gè)關(guān)鍵問題,包括元數(shù)據(jù)的分布問題,元數(shù)據(jù)的一致性和快速故障恢復(fù)問題,以及pb級(jí)機(jī)群文件系統(tǒng)的相關(guān)問題。
The cluster file systems for large - scale clusters should have multiple data paths and multiple metadata paths in architecture . metadata transactions are decoupled from file read and write operations . large - scale network storages are used to provide multiple file data paths 面向大規(guī)模機(jī)群的機(jī)群文件系統(tǒng)的體系結(jié)構(gòu)應(yīng)該是多數(shù)據(jù)通路多元數(shù)據(jù)通路的,即元數(shù)據(jù)處理與文件i / o分離,利用大規(guī)模網(wǎng)絡(luò)存儲(chǔ)系統(tǒng)來提供多條數(shù)據(jù)i / o通路,利用一組元數(shù)據(jù)服務(wù)器來提供多條元數(shù)據(jù)i / o通路。
At the same time , there maybe have some nodes in the cluster with low load and their buffer caches are n ' t used efficiently . on the analysis of linux virtual file system , cache models in cluster file system , mfs and the mechanism of dfsa , the paper import the provesion of cooperate caching to mfs and put forward the mechanism of mosix global cooperate caching ( mgcc ) , which can make all the buffer caches in the cluster cooperate when the cluster is working and make these buffer caches utilize fully , so the overall performance of the mfs can be improved 本文首先分析了mosix中單節(jié)點(diǎn)使用的linux虛擬文件系統(tǒng)緩存機(jī)制,對(duì)機(jī)群文件系統(tǒng)中的兩類緩存模型:三層緩存體系結(jié)構(gòu)和協(xié)作式緩存進(jìn)行了詳細(xì)的討論;在對(duì)mosix及其機(jī)群文件系統(tǒng)mfs和dfsa機(jī)制進(jìn)行深入研究的基礎(chǔ)上,本文把協(xié)作緩存機(jī)制引入到mfs中,提出了mosix全局協(xié)作緩存( mgcc )模型,改進(jìn)了mosix的緩存策略。
