Big data storage is a storage infrastructure that is designed specifically to store, manage and retrieve massive amounts of data, or big data. Big data storage enables the storage and sorting of big data in such a way that it can easily be accessed, used and processed by applications and services working on big data. Big data storage is also able to flexibly scale as required.
Big data storage primarily supports storage and input/output operations on storage with a very large number of data files and objects. A typical big data storage architecture is made up of a redundant and scalable supply of direct attached storage (DAS) pools, scale-out or clustered network attached storage (NAS) or an infrastructure based on object storage format. The storage infrastructure is connected to computing server nodes that enable quick processing and retrieval of big quantities of data. Moreover, most big data storage architectures/infrastructures have native support for big data analytics solutions such as Hadoop, Cassandra and NoSQL.
