Multiple VIM/VPOD Instances

Each VIM/VPOD instance or Open Stack is mapped to a separate EFA tenant. A VIM instance can be segregated as follows:

Grouping all physical interfaces together through topology specification
Restricting the VLAN range details in the Neutron initialization file

The following figure shows an example of multiple VIM/VPOD instances managing the same IP fabric.


VIM	EFA Tenant	BD	Properties
VIM1	OS-Tenant-VIM1	BD is disabled. CTAG is mapped to VLAN on the IP fabric.	VLAN-Range = 2-4080 specified in ml2_conf.ini `network_vlan_ranges = physnet1:2:4080` Physical interfaces can be specified using the topology.
VIM2	OS-Tenant-VIM2	BD is enabled. CTAG is mapped to BD on the IP fabric.	LAN-Range = 2-4080 specified in ml2_conf.ini `network_vlan_ranges = physnet1:2:4080` Tenant created with –bd-enable flag. Physical interfaces can be specified using the topology.

Example

The following example shows multiple VIM/VPOD instances.

# efa tenant create --name VIM1 --port 10.24.80.111[0/1],10.24.80.112[0/1] --vlan-range 2-4080  --vrf-count 200 

# efa tenant create --name VIM2 --port 10.24.80.112[0/2],10.24.80.113[0/1],10.24.80.114[0/1]  --enable-bd  --vlan-range 2-4080  --vrf-count 200
