Connecting the hardware to two compute nodes
Installation procedures for a two-node or multi-node system is the same as for a single-node system except for the following:
The two nodes are connected to each other through the two far-right 1Gb Ethernet ports on the rear of the nodes.
Both nodes connect to the Primary Storage Shelf.
Note:
The colored cables are for demonstration purposes only. There is only one type of SAS-3 cable.
Note:
Warning:
The hardware must be powered on in the expected order. Else, all the storage may not be seen by the appliance.
To connect a two-node appliance
- Identify the two ports on the lower right corner of both nodes.
- Connect Ethernet cables between the ports.
- Identify the SAS ports on the compute nodes.
- Identify the SAS ports on the Primary Storage Shelf.
- Connect the cables as follows:
On the compute node that is located closest to the Primary Storage Shelf, connect two SAS cables.
On the compute node that is located closest to the Primary Storage Shelf, connect two more SAS cables.
On the compute node that is located farthest from the Primary Storage Shelf, connect two SAS cables.
On the compute node that is located farthest from the Primary Storage Shelf connect two more SAS cables .
- If you have Expansion Storage Shelves, proceed to the following instructions.
See “To connect Expansion Storage Shelves to a Primary shelf”.
If you do not have Expansion shelves proceed to connect the power cords.
To connect Expansion Storage Shelves to a Primary shelf
- Obtain two SAS-3 cables.
- Locate the SAS-3 ports in the left-hand side of each controller in the Primary shelf.
- Locate SAS-3 ports A and C in both I/O modules of the Expansion shelves.
Port B is not used.
- If you have one Expansion shelf, connect it to the Primary shelf .
- If you have two Expansion shelves, connect them as shown.
- If you have three Expansion shelves connect them as shown.
- Proceed to the following section to connect power cords to the hardware.
