Both the SG5712 and SG5760 models of the StorageGRID appliance include an E5700SG controller and an E2800 controller. You should review the diagrams to learn the differences between the controllers.

E5700SG controller

  • Operates as the compute server for the appliance.

  • Includes the StorageGRID Appliance Installer.

    Note StorageGRID software is not preinstalled on the appliance. This software is accessed from the Admin Node when you deploy the appliance.

  • Can connect to all three StorageGRID networks, including the Grid Network, the Admin Network, and the Client Network.

  • Connects to the E2800 controller and operates as the initiator.

This figure shows the connectors on the back of the E5700SG controller.
