Learn the Difference Between SAN and NAS

Network attached storage technology is evolving. Important features, like scalability, can provide hundreds of terabytes of NAS space, while virtualization helps administrators organize and allocate NAS resources. If you're already familiar with NAS basics, this Guide focuses on the advanced hardware and architecture features, management concepts and backup practices. Download Chapter 4: NAS in.

An In-Depth Guide to the Differences Between SAN and NAS

A SAN is block-based storage, leveraging a high-speed architecture that connects servers to their logical disk units LUNs. A LUN is a range of blocks provisioned from a pool of shared storage and presented to the server as a logical disk. The server partitions and formats those blocks—typically with a file system—so that it can store data on the LUN just as it would on local disk storage. SANs make up about two-thirds of the total networked storage market. They are designed to remove single points of failure, making SANs highly available and resilient.

Data is the lifeblood of modern business, and modern data centers have extremely demanding requirements for size, speed, and reliability. Storage Basics Oftentimes, storage isn't given enough attention in system architecture, but it can make or SANs offer a higher level of functionality than DAS because it permits multiple hosts server computers to attach to NAS is optimized for ease-of-management and file sharing using lower-cost Ethernet-based networks.

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 other devices communicate with them. However, the two are sometimes used together to form what's known as a unified SAN. SAN and NAS technology does not require any specific computer operating system, although many of these devices use Linux under-the-hood. This NAS server authenticates clients and manages file operations in much the same manner as ordinary file servers, through well-established network protocols. To reduce the costs of standard file servers, NAS devices generally run an embedded operating system on simplified hardware and lack peripherals like a monitor or keyboard and are instead managed through a browser tool. The administrator of a home or small business network can connect one NAS device to a local area network.

These are my understandings of what they are. NAS not only operates as a file server, but is specialized for this task either by its hardware, software, or configuration of those elements. NAS is often made as a computer appliance — a specialized computer built from the ground up for storing and serving files — rather than simply a general purpose computer being used for the role. SANs are primarily used to make storage devices, such as disk arrays, tape libraries, and optical jukeboxes, accessible to servers so that the devices appear like locally attached devices to the operating system. A SAN typically has its own network of storage devices that are generally not accessible through the local area network by other devices. I don't know what that is or what that would look like if I saw one.
