POSIX Clients

Describes the usage of Data Fabric POSIX clients.

The Data Fabric file system supports direct and secure access to data using loopback NFS or FUSE-based POSIX clients.

The loopbacknfs POSIX client allows app servers, web servers, and other client nodes and apps to read and write data directly and securely to a Data Fabric cluster, with transmitted data compressed in both directions. The Data Fabric single-user mapr-loopbacknfs licenses gives secure access to one or more clusters, which allows native client applications to run securely on cluster data.

The FUSE-based POSIX basic and platinum clients run as a user space process to connect to one or more Data Fabric clusters and allow app servers, web servers, and applications to read and write data directly and securely to the Data Fabric clusters like a Linux file system. Each client implies a specific Data Fabric file system throughput optimization of n/G per second.

Both loopbacknfs and FUSE-based POSIX clients can be installed on supported Linux and Ubuntu distributions and require direct network access to all Data Fabric cluster nodes. They connect to the Data Fabric cluster directly (no NFS gateway) to read and write data securely.
