Cabling the appliance

You must connect the two controllers to each other, connect the management ports on each controller, and connect the 10/25-GbE ports on the E5700SG controller to the Grid Network and optional Client Network for StorageGRID Webscale.

Before you begin

Note: Eight SFP+ transceivers are included with the appliance shipment. These transceivers support either 10GbE or 16Gbps FC and can be used with the two interconnect ports on both controllers and with the four 10GbE/25GbE network ports on the E5700SG controller (assuming you want the network ports to use a 10-GbE link speed).
CAUTION:
Risk of exposure to laser radiation – Do not disassemble or remove any part of an SFP transceiver. You might be exposed to laser radiation.

About this task

The figure shows the two controllers in the SG5760, with the E2800 controller on the top and the E5700SG controller on the bottom. In the SG5712, the E2800 controller is to the left of the E5700SG controller when viewed from the back.


Connections on the SG5760 appliance
  Port Type of port Function
1 Two interconnect ports on each controller

16Gb/s FC optical SFP+

Connect the two controllers to each other.
2 Management port 1 on the E2800 controller 1-Gb (RJ-45) Ethernet Connects to the network where you access SANtricity System Manager. You can use the Admin Network for StorageGRID Webscale or an independent management network.
Management port 2 on the E2800 controller 1-Gb (RJ-45) Ethernet Reserved for technical support.
3 Management port 1 on the E5700SG controller 1-Gb (RJ-45) Ethernet Connects the E5700SG controller to the Admin Network for StorageGRID Webscale.
Management port 2 on the E5700SG controller 1-Gb (RJ-45) Ethernet Can be used to connect the E5700SG controller to a service laptop during installation, if a DHCP-assigned IP address is not available.
4 10/25-GbE ports 1-4 on the E5700SG controller 10-GbE or 25-GbE
Note: The SFP+ transceivers included with the appliance support 10-GbE link speeds. If you want to use 25-GbE link speeds for the four network ports, you must provide SFP28 transceivers.
Connect to the Grid Network and the Client Network for StorageGRID Webscale. See "10/25-GbE port connections for the E5700SG controller."

Steps

  1. Connect the E2800 controller to the E5700SG controller, using two optical cables and four of the eight SFP+ transceivers.
    Connect this port... To this port...
    Interconnect port 1 on the E2800 controller Interconnect port 1 on the E5700SG controller
    Interconnect port 2 on the E2800 controller Interconnect port 2 on the E5700SG controller
  2. Connect management port 1 (P1) on the E2800 controller (the RJ-45 port on the left) to the management network for SANtricity System Manager, using an Ethernet cable.
    Do not use management port 2 (P2) on the E2800 controller (the RJ-45 port on the right). This port is reserved for technical support.
  3. If you plan to use the Admin Network for StorageGRID Webscale, connect management port 1 on the E5700SG controller (the RJ-45 port on the left) to the Admin Network, using an Ethernet cable.
  4. Connect the 10/25-GbE ports on the E5700SG controller to the appropriate network switches, using optical cables and SFP+ or SFP28 transceivers.
    Note: All ports must use the same link speed. Install SFP+ transceivers if you plan to use 10-GbE link speeds. Install SFP28 transceivers if you plan to use 25-GbE link speeds.
    • If you plan to use Fixed port bond mode (default), connect the ports to the StorageGRID Webscale Grid and Client Networks, as shown in the table.
      Port Connects to...
      Port 1 Client Network (optional)
      Port 2 Grid Network
      Port 3 Client Network (optional)
      Port 4 Grid Network
    • If you plan to use the Aggregate port bond mode, connect one or more of the network ports to one or more switches. You should connect at least two of the four ports to avoid having a single point of failure. If you use more than one switch for a single LACP bond, the switches must support MLAG or equivalent.
