11.2 Cable SMU and 36-Port InfiniBand EDR LDN with Dual 48-Port
LMN Switches
About this task
For ClusterStor L300 and L300N inter-rack 36-port EDR InfiniBand LDN switch cabling, the available uplink ports
are:
●
Upper switch 1 (IB1) - ports 1 through 21, 23, 25, 26, 29, 31, 33, and 35
●
Lower switch 0 (IB0) - ports 1, 3, 5, 7, 9, 11, 13, 15, 17 through 36
For inter-rack Ethernet switch cabling, the available uplink ports are:
●
Upper switch 1 (SW1) - ports 1 through 24, 29, 31, 41, and 43
●
Lower switch 0 (SW0) - ports 1 through 24, 29, 31, 41, and 43
IMPORTANT: For inter-rack LMN Ethernet 48-port switch cabling, ports 1 through 24, and 29, 31, 41, and
43 are available uplink ports. Note that port 37 is the ISL and is not available.
IMPORTANT: Switch port assignments in the configuration diagrams are provided for reference only. For
system-specific inter-rack switch cabling, refer to the system-specific storage configuration document
(SCD).
