components. Monolithic architectures support both block and file-based architectures, either independently or in a unified storage system that brings together both block and file. Direct-attached storage Direct-attached storage (DAS) provides scaling of storage directly attached to the server. The storage is dedicated to a single server and is not sharable among multiple servers. Data stored on a Storage area network (SAN) and network-attached storage (NAS) architectures can be shared among several server applications. References Computer data storage
