DataPlow Products

DataPlow has two SAN-based, clustered file system product lines: SAN File System (SFS) and Nasan clustered file system. Due to unique, patented designs, both file systems fully exploit the high-speed, scalable data transfers inherent to SANs. Though architecturally similar, the file systems are tuned for different environments and workloads. DataPlow SFS is a general-purpose file system for a wide variety of environments, whereas Nasan specifically targets read-intensive workloads.

SAN File System

DataPlow SAN File System is software that enables high-speed, yet secure, access to shared files located on SAN-attached storage devices. SFS is easy to manage, resilient to hardware failures, and simple to integrate into any environment.
 
The following figure illustrates an SFS environment. Computers A, B, and C running DataPlow SFS connect to storage devices via the SAN. Additionally, computers B and C operate as NFS and/or CIFS file servers and extend file sharing to LAN-based computers D and E.

Nasan Clustered File System

DataPlow Nasan clustered file system software utilizes scalable SANs and central file servers to facilitate high-performance file sharing. The SAN carries out high-speed data transfers, while the file servers ensure low-latency data consistency. Nasan is ideal for read-intensive workloads.
 
Nasan clustered file sharing is an extension of traditional LAN file sharing. Deploying a Nasan cluster simply entails configuring LAN file sharing, installing Nasan file system software, and connecting computers and storage devices to the SAN. Upgrading an existing LAN, which already utilizes SAN-attached storage, merely involves installing software and connecting the SAN; downtime is minimal because all previously stored files remain unaffected by the upgrade.
 
The following figure illustrates a Nasan cluster environment that contains one or more computers running DataPlow Nasan, SAN-attached storage devices, and at least one, non-dedicated file server.
