IBM manual DS Storage Manager Web-based interface, 16 DS8000 Copy Services network components

from these interfaces, S-HMC communicates with each server in the storage units via the Ethernet network. Therefore, the S-HMC is a key component to configure and manage the DS8000.

The network components for Copy Services are illustrated in Figure 7-16.

Each DS8000 will have an internal S-HMC in the base frame, and you can have an external S-HMC for redundancy.

For further information about the S-HMC, see Chapter 9, “Configuration planning” on page 157.

7.3.2 DS Storage Manager Web-based interface

DS Storage Manager is a Web-based management interface. It is used for managing the logical configurations and invoking the Copy Services functions. The DS Storage Manager has an online mode and an offline mode; only the online mode is supported for Copy Services.

DS Storage Manager is already installed in the S-HMC. You can also install it in other computers that you prepare. When you manage the Copy Services functions with DS Storage Manager in your computers, DS Storage Manager issues its command to the S-HMC via the Ethernet network.

The DS Storage Manager can be used for almost all functions for Copy Services. The following functions cannot be issued from the DS Storage Manager in the current implementation:

￿Consistency Group operation (FlashCopy and PPRC)

￿Inband commands over Remote Mirror link
