Q: What is Storage Area Network (SAN) Storage?
A: A Storage Area Network (SAN) is a scaleable, high-speed network. SAN Storage provides block-level network access to storage. SANs are typically composed of hosts, switches, storage elements, and storage devices that are interconnected using a variety of technologies, topologies, and protocols.
Q: What is Network Area Storage (NAS) Storage?
A: NAS Storage or Network Attached Storage is a storage device connected to a network that allows storage and retrieval of data from a centralized location for authorized network users.
Q: What is the difference between NAS Storage and SAN Storage?
A: SAN and network-attached storage (NAS) are both network-based storage solutions. A SAN typically uses Fibre Channel connectivity, while NAS typically ties into to the network through a standard Ethernet connection. A SAN stores data at the block level, while NAS accesses data as files.
