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:

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
