Up to fifteen hosts can share a VTSS in this configuration. F igure 5. In figure 5, each host manages its attached VTSS, as in the figure 2 example. If both hosts were attached to both VTSSs, the system would operate like the figure 4 example. Each host could be connected to each VTSS and the VTDs shared by those hosts.
Virtual mounts occur in less than a second.
Read requests for VTVs resident in the disk buffer are satisfied immediately at disk speeds. Physical media utilization. VSM host software stacks multiple VTVs on a single MVC to maximize media utilization, and reduce the number of physical mounts required by the solution. Real tape transport requirements and utilization. VSM requires fewer physical tape mounts to accommodate a larger number of fast, virtual mounts.
