【摘要】:正在IT運營過程中,應(yīng)用系統(tǒng)時常會出現(xiàn)熱點數(shù)據(jù)(如數(shù)據(jù)庫發(fā)生IO性能瓶頸產(chǎn)生業(yè)務(wù)影響),且往往只有在問題發(fā)生后才能被動發(fā)現(xiàn),并經(jīng)常依靠技術(shù)人員將熱點數(shù)據(jù)遷移到后端帶寬更大的盤組來消除熱點。近年來,隨著云技術(shù)和大數(shù)據(jù)的廣泛應(yīng)用,數(shù)據(jù)中心的數(shù)據(jù)量呈爆發(fā)式增長,數(shù)據(jù)熱點出現(xiàn)日益頻繁,但因底層磁盤機上的冷熱數(shù)據(jù)難以被有效、快速評估,導(dǎo)致影響業(yè)務(wù)正常運行的情況時有發(fā)生。分層存儲是建立在存儲池基礎(chǔ)上發(fā)展而來的一種新
[Abstract]:In the process of IT operation, application systems often have hot data (such as IO performance bottleneck in database to produce business impact), and they can only be found passively only after the problem has occurred. And often rely on technicians to migrate hot data to backend bandwidth greater disk groups to eliminate hot spots. In recent years, with the extensive application of cloud technology and big data, the amount of data in data center increases explosively, and data hot spots appear more and more frequently. However, the cold and hot data on the underlying disk machine are difficult to be effectively evaluated. Causes the normal operation of the business to occur from time to time. Hierarchical storage is a new kind of storage developed on the basis of storage pool.
