Connecting the hardware
This section provides cabling information for a Veritas Access 3340 Appliance that includes two compute nodes, one Primary Storage Shelf, and up to three Expansion Storage Shelves.
Expansion Storage Shelves connect to the Primary shelf and to other Expansion shelves with two SAS3 cables.
Each compute node is connected to the Primary Storage Shelf with four SAS3 cables.
The compute nodes connect to each other with two Ethernet cables.
The Primary shelf has a single SAS3 port on the left side of each RAID controller I/O module. This port connects to SAS3 port A in the Expansion I/O modules.
Warning:
The hardware must be powered on in the expected order. Else, all the storage may not be seen by the appliance.
To connect two compute nodes to a Primary shelf
- Obtain two Ethernet cables.
- Identify the two Ethernet ports on the far right of the compute node rear panels.
- Connect the cables between the ports .
- Obtain four SAS3 cables for each compute node.
- Identify the SAS3 ports in slot 1 and slot 4 of the compute node that is closest to the Primary shelf.
The ports in each slot are labeled 3, 2, 1, and 0 from left to right.
- Identify the four SAS3 ports in each Primary shelf controller.
The left-hand controller is labeled A and the right-hand controller is labeled B.
The ports in each controller are labeled 3, 2, 1, and 0 from left to right.
Note:
The colors of the cables in the following diagrams are for demonstration purposes only.
- On the compute node that is closest to the Primary shelf connect Slot 1, Port 3 to controller B, Port 2 on the Primary shelf.
The blue tab on the SAS3 cable must point up towards the top of the shelf.
- On the same compute node connect Slot 1, Port 2 to controller A, Port 2 on the Primary shelf.
- On the same compute node connect Slot 4, Port 3 to controller B, Port 3 on the Primary shelf.
- On the same compute node connect Slot 4, Port 2 to controller A, Port 3 on the Primary shelf.
- On the other compute node connect Slot 1, Port 3 to controller B, Port 0 on the Primary shelf.
- On this compute node connect Slot 1, Port 2 to controller A, Port 0 on the Primary shelf.
- On this compute node connect Slot 4, Port 3 to controller B, Port 1 on the Primary shelf.
- On this compute node connect Slot 4, Port 2 to controller A, Port 1 on the Primary shelf.
- Use the following procedure to connect Expansion Storage Shelves to the Primary shelf.
See “To connect Expansion Storage Shelves to a Primary shelf”.
If you do not have any Expansion shelves at this time, proceed to the following section to connect power cords to the hardware.
To connect Expansion Storage Shelves to a Primary shelf
- Do the following if you have one Expansion shelf.
Connect one end of two SAS3 cables to the SAS3 port on the left hand side of each RAID controller in the Primary shelf.
The blue tab on the cable must face down in this port.
Connect the other end of the SAS3 cables to port A in each of the I/O modules in the Expansion shelf.
The blue tab on the cable must face down in the Expansion shelf.
- Do the following if you have two Expansion shelves.
Connect one end of the two SAS3 cables to the SAS3 port on the left hand side of each RAID controller in the Primary shelf.
Connect the other end of the SAS3 cable in RAID controller A to port A in the nearest Expansion shelf I/O module on the left side of the shelf.
Connect the other end of the SAS3 cable in RAID controller B to port A in the right-hand I/O module in the lower Expansion shelf.
Connect port C in I/O module A of the upper Expansion shelf to port A in I/O module A of the lower Expansion shelf.
Connect port A in I/O module B of the upper Expansion shelf to port C in I/O module B of the lower Expansion shelf.
- Do the following if you have three Expansion shelves.
Connect one end of the two SAS3 cables to the SAS3 port on the left hand side of each RAID controller in the Primary shelf.
Connect the other end of the SAS3 cable in RAID controller A to port A in the nearest Expansion shelf I/O module on the left side of the shelf.
Connect the other end of the SAS3 cable in RAID controller B to port A in the right-hand I/O module in the lowest Expansion shelf.
Connect port C in I/O module A of the upper Expansion shelf to port A in I/O module A of the middle Expansion shelf.
Connect port A in I/O module B of the upper Expansion shelf to port C in I/O module B of the middle Expansion shelf.
Connect port C in I/O module A of the middle Expansion shelf to port A in I/O module A of the lowest Expansion shelf.
Connect port A in I/O module B of the middle Expansion shelf to port C in I/O module B of the lowest Expansion shelf.
