With SAN File System, you can create and use named pipes (or FIFO objects) in the global namespace. A FIFO object is a standard UNIX® feature that is used to communicate and exchange data between processes. It has a directory name and is accessed by a path name. Its file size and a block size are always 0.
When a UNIX-based client creates a FIFO object, its file name becomes visible to all other clients, just like any other file. Users and applications on any UNIX-based client can perform standard file-system operations on a FIFO object; however the data-passing operation of the FIFO object is local to the client. In other words, data in a FIFO object is only readable to processes local to the same client that wrote the data. Data in FIFO objects is not passed between clients.
Although FIFO objects are visible to Windows® clients (subject to file permissions), Windows-based clients cannot create, read from, or write to FIFO objects.
