Cabling the appliance

You must connect the two controllers to each other with SAS interconnect cables, connect the management ports to the appropriate management network, and connect the 10 GbE ports on the E5600SG controller to the Grid network and optional Client network for StorageGRID Webscale.

About this task

When connecting the cables, refer to the following diagram, which shows the E2700 controller on the top and the E5600SG controller on the bottom. The diagram shows the SG5660 model; the controllers in the SG5612 model are side by side instead of stacked.

Item Port Type of port Function
1 Management port 1 on the E2700 controller 1-Gb (RJ-45) Ethernet Connects the E2700 controller to the network where SANtricity Storage Manager is installed.
2 Management port 2 on the E2700 controller 1-Gb (RJ-45) Ethernet Connects the E2700 controller to a service laptop during installation.
3 Two SAS interconnect ports on each controller, labelled Ch 1 and Ch 2

E2700 controller: mini-SAS-HD

E5600SG controller: mini-SAS

Connect the two controllers to each other.
4 Management port 1 on the E5600SG controller 1-Gb (RJ-45) Ethernet Connects the E5600SG controller to the Admin network for StorageGRID Webscale.
5 Management port 2 on the E5600SG controller 1-Gb (RJ-45) Ethernet Connects the E5600SG controller to a service laptop during installation.
6 Four network ports on the E5600SG controller 10-GbE (optical) Connect the E5600SG controller to the Grid network and to the Client network (if used) for StorageGRID Webscale. The ports can be bonded together to provide redundant paths to the controller.
When connecting the 10-GbE network ports on the E5600SG controller, note that version 1.7 and later of the StorageGRID Webscale Appliance Installer supports two configurations for these ports, as follows:
  • In the Fixed Port Configuration, ports 2 and 4 are bonded together for the Grid network, and ports 1 and 3 are bonded together for the Client network, if used. The ports can be bonded using active-backup mode or Link Aggregation Control Protocol mode (LACP IEEE 802.3ad).
  • In the optional Aggregated Port Configuration, all four ports are grouped together in a single LACP bond, and all ports are used for both Grid network and Client network traffic. If you plan to use Aggregated Port Configuration:
    • You must be using version 1.7 or later of the StorageGRID Webscale Appliance Installer.
      Note: You cannot determine which version of the StorageGRID Webscale Appliance Installer is included with the appliance until you configure the E5600SG controller management port. If you discover that you need to upgrade the StorageGRID WebscaleAppliance Installer to version 1.7, you must contact technical support.
    • The ports must be connected to switches that can support VLAN, LACP, or multi-chassis link aggregation groups (MLAG), or equivalent, if multiple switches are participating in the LACP bond.
    • You must understand how to configure the switches to use VLAN, LACP, or MLAG, or equivalent, if multiple switches are participating in the LACP bond.

For more information, see the appropriate StorageGRID Webscale Installation Guide.

Steps

  1. Connect the E2700 controller to the E5600SG controller, using the two SAS interconnect cables.
    Connect this port... To this port...
    SAS interconnect port 1 (labeled Ch 1) on the E2700 controller SAS interconnect port 1 (labeled Ch 1) on the E5600SG controller
    SAS interconnect port 2 (labeled Ch 2) on the E2700 controller SAS interconnect port 2 (labeled Ch 2) on the E5600SG controller
    Use the square connector (mini-SAS HD) for the E2700 controller, and use the rectangular connector (mini-SAS) for the E5600SG controller.
    Attention: Make sure the pull tabs on the SAS connectors are at the bottom, and carefully insert each connector until it clicks into place. Do not push on the connector if there is any resistance. Verify the position of the pull tab before continuing.
  2. Connect the E2700 controller to the management network where SANtricity Storage Manager software is installed, using an Ethernet cable.
    Connect this port... To this port...
    Port 1 on the E2700 controller (the RJ-45 port on the left) Switch port on the management network used for SANtricity Storage Manager
    Port 2 on the E2700 controller Service laptop, if not using DHCP
  3. Connect the E5600SG controller to the Admin network for StorageGRID Webscale, using an Ethernet cable.
    Connect this port... To this port...
    Port 1 on the E5600SG controller (the RJ-45 port on the left) Switch port on the Admin network for StorageGRID Webscale
    Port 2 on the E5600SG controller Service laptop, if not using DHCP
  4. Using 10-GbE optical cables and SFP transceivers as required, connect the 10-GbE optical ports on the E5600SG controller to the appropriate switch ports.
    • If you plan to use the Fixed Port Configuration, or if the E5600SG controller includes version 1.6 or earlier of the StorageGRID Webscale Appliance Installer, connect the ports as shown in the table.
      Connect this port.... To this port...
      E5600SG controller Port 1 Switch port on Client network for StorageGRID Webscale (optional)
      E5600SG controller Port 2 Switch port on Grid network for StorageGRID Webscale
      E5600SG controller Port 3 Switch port on Client network for StorageGRID Webscale (optional)
      E5600SG controller Port 4 Switch port on Grid network for StorageGRID Webscale

      If you have version 1.7 or later of the StorageGRID Webscale Appliance Installer, you can specify how the ports should be bonded (either active-backup mode or LACP (802.3ad) mode) when you configure the appliance. You can also optionally specify VLAN IDs for each network.

    • If you plan to use the Aggregate Port Configuration, connect all four ports to one or more switches. When you configure the appliance with the StorageGRID Webscale Appliance Installer, you must specify VLAN IDs for the Grid network and the Client network. See your switch documentation for more instructions.
    Warning: Risk of exposure to laser radiation – Do not disassemble or remove any part of an SFP transceiver because you might be exposed to laser radiation.
