HPSS Servers
HPSS servers include the Core Server, Migration/Purge Server, Gatekeeper, Location Server, Log Client, Log Daemon, Physical Volume Library, Physical Volume Repository, Mover, Storage System Management System Manager, and Startup Daemon. Figure 3: HPSS Components provides a simplified view of the HPSS system. Each major server component is shown, along with the basic control communication paths (thin arrowed lines). Infrastructure items (those components that “glue together” the distributed servers) are shown at the top of the cube. These infrastructure items are discussed in Section 2.3.4: HPSS Infrastructure on page 31. HPSS user interfaces (the clients listed in the figure) are also discussed in Section 2.3.5: HPSS User Interfaces on page 34.
