SAN VS NAS •Storage Area Networks (SAN) and Network Attached Storage
SAN VS NAS •Storage Area Networks (SANs) and Network Attached Storage (NAS) both provide networked storage solutions. A NAS is a single storage device that operates on data files, while a SAN is a local network of multiple devices that operate on disk blocks. •The differences between NAS and SAN can be seen when comparing their cabling and how they’re connected to the system, as well as how communication to the device is performed.
•SAN vs NAS Technology • A NAS includes a dedicated hardware device called the head that connects to a local area network, usually through Ethernet. This NAS server authenticates clients and manages file operations in much the same manner as traditional file servers, through well-established network protocols like NFS and CIFS/SMB. •To reduce the cost compared to traditional file servers, NAS devices generally run an embedded operating system on simplified hardware and lack peripherals like a monitor or keyboard. •A SAN commonly utilizes Fibre Channel interconnects and connects a set of storage devices that are able to share low-level data with each other. •
