The Nasan Clustered File System is a
shared disk file system
A clustered file system is a file system which is shared by being simultaneously mounted on multiple servers. There are several approaches to clustering, most of which do not employ a clustered file system (only direct attached storage for ...
created by the company DataPlow. Nasan software enables high-speed access to shared files located on shared,
storage area network
A storage area network (SAN) or storage network is a computer network which provides access to consolidated, block-level data storage. SANs are primarily used to access data storage devices, such as disk arrays and tape libraries from ser ...
(SAN)-attached storage devices by utilizing the high-performance, scalable data transfers inherent to storage area networks and the manageability of
network attached storage
Network-attached storage (NAS) is a file-level (as opposed to block-level storage) computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. The term "NAS" can refer to both the tech ...

Nasan derives its name from the combination of network attached storage (NAS) and storage area network (SAN). Nasan clustered file sharing is an extension of traditional LAN file sharing yet utilizes storage area networks for data transfers. Deploying a Nasan cluster entails configuring LAN file sharing, installing Nasan file system software, and connecting computers and storage devices to the SAN.
