Following the proposal of a softwaredefined technology, solutions to the concepts of software-defined data centers and software-defined storage have also been proposed. A virtual storage area network (vSAN) has a relatively scalable architecture, supports solid-state drives, and provides an expansion mechanism in the form of scale-up and scale-out storage. We conducted an in-depth study in which we measured the performance of the 3D virtual application cloud service (3D-VACS) on a university campus. The 3D-VACS constitutes the distributed file system (DFS), heterogeneous network, and high-performance environments for a vSAN. A greater number of disk stripes was discovered to improve the performance of big block transfers, i.e., when 10 disk stripes were employed, the performance was 2.46 times higher than when 1 disk stripe was used. The highest performance improvement, 32%, was obtained in a test requiring simultaneous reading and writing in a heterogeneous network environment, providing a faster network; when the write-only requirement was enforced, the performance did not improve significantly, although it was greater than that observed for the read/write hybrid requirement. Scale-out improved operational performance by 69% in an environment that required large amounts of reading and writing. In multimedia server data storage or applications in a file server storage environment, scale-up was observed to improve performance by up to 48%
