Connecting ES30 shelves
The cabling diagrams in this section show the maximum configurations for the
DD6300, DD6800, and DD9300 systems. Not all systems will have all the disk shelves
shown in the diagrams.
Add shelf-to-shelf cables between shelves in a loop and to the controller as shown in
the diagrams.
1.
Cable from the B Controller EXPANSION
port of the lower shelf to the B
controller HOST port of the next higher shelf.
2. Then cable from the A Controller HOST port of lower shelf to the A controller
EXPANSION
port of the next higher shelf
3. There are no specific placement or cabling requirements for SSD shelves, or the
metadata shelves for DD Cloud Tier configurations. These shelves can be installed
and cabled the same way as standard ES30 shelves. SSD shelves and DD Cloud
Tier metadata do not need to be cabled in a separate set from the other ES30
shelves.
For HA pairs, the primary and standby nodes use different cables to connect to ES30
shelves. The primary node uses cables for ES30 host ports (
), and the standby node
uses cables for ES30 expansion ports (
).
ES30 cable information
When connecting ES30 shelves, different cables are required for the following
connections:
l
Connecting the primary node to the ES30 shelf loop
l
Connecting the standby node to the ES30 shelf loop
l
Connecting an ES30 shelf to an ES30 shelf within a loop
