Carrying
on from the
previous post, the following diagrams illustrate the cluster cabling with 2
x CN1610 switches (initial), with 1 x CN1610 and 1 x NX3132Q-V switch
(interim), and with 2 x NX3132Q-V switches (final). We use an example of a
4-node cluster with FAS8040A/FAS8060A controllers (two controllers in one
shared chassis), using e0a and e0c ports for cluster network.
Note: The official documentation is here -
- one change I would suggest is to re-home and
revert cluster LIFs instead of just migrating them (since cluster LIFs will
auto-revert).
1) Initial Setup

FAS8040A/FAS8060A cluster with 2 x CN1610
2) Interim Setup (replaced CN1610 switch 2 with
NX3132Q-V switch 2)
Here we
use 3 of the 40GbE to 4 x 10GbE breakout cables:
- 1
breakout cable is used for a temporary ISL.
- 1
breakout cable connects port 1 of switch 2 to nodes 1 & 2 e0c (HA-Pair 1) and
this leaves 2 of the 4 10GbE breakouts spare.
- 1
breakout cable connects port 2 of switch 2 to nodes 3 & 4 e0c (HA-Pair 2) and
this leaves 2 of the 4 10GbE breakouts spare.

3) Final Setup (replaced CN1610 switch 1 with
NX3132Q-V switch 1)
Here we
use:
- 1 breakout
cable connects port 1 of switch 1 to nodes 1 & 2 e0a (HA-Pair 1) and this
leaves 2 of the 4 10GbE breakouts spare.
- 1
breakout cable connects port 2 of switch 1 to nodes 3 & 4 e0a (HA-Pair 2) and
this leaves 2 of the 4 10GbE breakouts spare.
The temporary
ISL cable is removed and we use 2 x ‘Optical Fibre: 40Gbps MPO to 40Gbps MPO’
for the ISLs.
