High-Density Capacity on Demand

Use the High Density (HD) Capacity on Demand (CoD) license key to enable the full high-density capacity of the Lx5, Dx5, and Sx5 frames in the TS4500 tape library. Enabling the CoD on the TS4500 is a non-disruptive process.

The initial (entry) capacity of the Lx5 frames is 100 slots. The Intermediate and Base CoD features can increase the usable capacity up to 400 slots. The HD CoD features add anywhere from 150 to more than 450 more slots, depending on frame position and configuration. The Base CoD feature (FC 1644) is a prerequisite for installing an HD CoD feature on an Lx5 frame.

The initial (entry) capacity of the Dx5 frames is 500 slots. The initial (entry) capacity of the S25 frame is 600 slots and of the S55 frame is 660 slots. The HD CoD features can add anywhere 50 - 660 more slots, depending on frame position and configuration.

Table 1 shows potential capacities by frame model.
