Controllers in the StorageGRID appliance

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.

	Port	Type	Use
1	Interconnect ports 1 and 2	16Gb/s Fibre Channel (FC), optical SFP+	Connect the E5700SG controller to the E2800 controller.
2	Diagnostic and support ports	RJ-45 serial port Micro USB serial port USB port	Reserved for technical support.
3	Drive expansion ports	12Gb/s SAS	Not used. StorageGRID appliances do not support expansion drive shelves.
4	Network ports 1-4	10-GbE or 25-GbE, based on SFP transceiver type, switch speed, and configured link speed	Connect to the Grid Network and the Client Network for StorageGRID.
5	Management port 1	1-Gb (RJ-45) Ethernet	Connect to the Admin Network for StorageGRID.
6	Management port 2	1-Gb (RJ-45) Ethernet	Options: Bond with management port 1 for a redundant connection to the Admin Network for StorageGRID. Leave unwired and available for temporary local access (IP 169.254.0.1). During installation, use port 2 for IP configuration if DHCP-assigned IP addresses are not available.

E2800 controller

• Operates as the storage controller for the appliance.
• Manages the storage of data on the drives.
• Functions as a standard E-Series controller in simplex mode.
• Includes SANtricity OS Software (controller firmware).
• Includes SANtricity System Manager for monitoring appliance hardware and for managing alerts, the AutoSupport feature, and the Drive Security feature.
• Connects to the E5700SG controller and operates as the target.

This figure shows the connectors on the back of the E2800 controller.

	Port	Type	Use
1	Interconnect ports 1 and 2	16Gb/s FC optical SFP+	Connect the E2800 controller to the E5700SG controller.
2	Management ports 1 and 2	1-Gb (RJ-45) Ethernet	Port 1 connects to the network where you access SANtricity System Manager on a browser. Port 2 is reserved for technical support use.
3	Diagnostic and support ports	RJ-45 serial port Micro USB serial port USB port	Reserved for technical support use.
4	Drive expansion ports.	12Gb/s SAS	Not used. StorageGRID appliances do not support expansion drive shelves.
