![]() NAS is generally associated with unstructured data such as video and medical images, while SAN is associated with structured workloads such as databases. To a client OS, NAS appears as a file server, while a SAN typically appears as a disk and exists as its own separate network of storage devices. NAS accesses data as files, while a SAN stores data at the block level. NAS typically ties into to the network through a standard Ethernet connection, while a SAN typically uses Fibre Channel connectivity. NAS and storage-area networks (SAN) are both network-based storage solutions. Example vendors that offer enterprise NAS products include Dell EMC, NetApp, Hewlett-Packard Enterprise, IBM and Hitachi Vantara. ![]() ![]() Vendors offer compact NAS appliances at the low end, traditional NAS servers for rack settings, and high-end systems that expand into the multi-petabyte range. “It can leverage the SMB protocol, which is predominantly for Windows, or the NFS protocol, which is predominately for Linux – those tend to be two big file-based protocols for NAS.” What NAS form factors are available? And you can set up lots of different shared drives,” says Scott Sinclair, senior analyst with Enterprise Strategy Group. When you set up a NAS, it looks like a giant shared drive. In an enterprise setting, NAS can allow IT teams to streamline data storage and retrieval while consolidating their server and storage infrastructure. NAS devices typically consist of bundled hardware and software with a built-in operating system, and they typically use industry-standard network protocols such as SMB and NFS for remote file service and data sharing and TCP/IP for data transfer. NAS evolved from file servers used in the 1980s to provide access to files for network clients. NAS history: evolution of network-attached storage ![]()
