IBM's SSA (Serial Storage Architecture) has been sold primarily to customers of IBM's RS/6000 product line. While it is also available on HP and Sun platforms, its acceptance on them has not been very strong. Fibre channel encompasses three networking topologies: point-to-point, loop, and fabric.

The compelling story of open source software is the rock-bottom cost. When one takes all the components of a file server into account, the hardware costs have been decreasing significantly from year to year, while the software costs have stayed fairly level. Open source software moves the software cost to as low as it can get, which certainly promises to significantly reduce the cost of server systems.
Virtual memory extends the available physical addresses of system memory by mapping additional memory addresses to storage devices that reside outside the system memory bus. The operating system uses virtual memory to transfer low-demand instructions and data to make room for more instructions and data that are more crucial. Two types of virtual memory operations are demand paging and segment swapping. Most modern operating systems use one or the other to manage their memory resources. When instructions and data being held in virtual memory are needed again by the CPU, they are loaded back into physical memory for the CPU to access.
