Drafting the Connection Topology (Direct-Connection Network)
This section describes cable connections between controller enclosures. If a storage system has two or more controller enclosures, each controller in every controller enclosure must be connected to application servers. For details, see "Connection Planning for Multiple Controller Enclosures and One Application Server" in the Installation Guide specific to your product model and version.
Figure 11-1 shows the networking diagram of expanding controllers from 2 to 6, 4 to 6, 2 to 8, 4 to 8, and 6 to 8.
- This section uses a storage system with SAS disk enclosures as an example to describe the networking, which is the same as that of a storage system with smart disk enclosures.
- For V500R007C70 and later versions, if you want to remotely power on the storage system, connect the cables (green cables) of the maintenance network ports as instructed in the figure. In other cases, you do not need to connect the green cables. For details about remote power-on, see "Powering on the Storage System (Remotely on the CLI)" in the Administrator Guide specific to your product model and version.
