Study Notes
Introduction to Storage Technology: Primary Storage, Secondary Storage, NAS, and SAN
- Storage technology is where data is stored in digital format for retrieval at a later point in time.
- Storage devices are computing hardware used for storing, porting, and extracting data files or objects.
- Primary storage devices are internal to a computer or server, hold data temporarily, and have limited capacity.
- Secondary storage devices are larger in capacity, can be internal or external, and can hold data permanently or temporarily.
- The measure of storage capacity is in bits and bytes, with 1 GB being equivalent to 1024 kilobytes and 1 PB being equivalent to 1024 terabytes.
- The exponential growth of data led to the need for storage technologies such as NAS and SAN.
- NAS devices connect storage to a network, where they are accessed through file shares by multiple systems with permissions.
- SAN is a dedicated network that allows storage to be shared between multiple servers, and data is stored in volumes or blocks.
- SAN devices provide continuous and fast access to large amounts of data, and communication and data transfer mechanism is through storage fabric.
- SAN uses separate networks and is generally not accessible by other devices in the local area network.
- NAS is optimized for file serving, whereas SAN is a block-level device that provides greater flexibility and additional functionalities.
- Despite the differences between NAS and SAN, they blend together well, with many NAS providing support for iSCSI and many SAN providing support for SMB and NAS file systems.
