Network-Attached Storage (NAS)
Network-attached storage (NAS) is dedicated file storage that facilitates multiple users even in a heterogeneous client device to retrieve data from centralised disk capacity. Users on a local area network (LAN) obtain the shared storage via a standard Ethernet connection.
Storage Area Network (SAN)
A storage area network (SAN) is a dedicated low-latency with an ultra-speedy cluster of harddisks that interconnects and offers distributed pools of storage devices to multiple servers.
Unified Storage or Multi-Protocol Storage
Unified storage is a fusion of both SAN and NSA with storage space connected to a network that provides file-based and block-based data storehouse services to other devices on the network.
There are many vendors for storage. However, the two most dominant players in the enterprise
- EMC (now a part of Dell).
