摘要: According to one embodiment, a system includes virtual tape library having cache, controller (VTC) coupled the library, and an interface for coupling multiple hosts VTC. The cache is shared by hosts, common view of state, number write requests pending provided In another method receiving data from at least host using VTC, storing received all sending alert when free space low entering into warning critically critical state while allowing previously mounted drives continue normally.
