Controllers in the StorageGRID Webscale appliance

Both the SG5712 and SG5760 models of the StorageGRID Webscale 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 Webscale 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 Webscale networks, including the Grid Network, the Admin Network, and the Client Network.
  • Connects to the E2800 controller and operates as the initiator.
Note: The E5700SG controller is highly customized for use in the StorageGRID Webscale appliance. Do not use E-Series procedures for this controller unless instructed otherwise. For more information, see "Maintaining the SG5700 appliance."

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