Integrating With VMWARE

In Virtual Infrastructure Integration , VMware is the very important technology which ACI integrates via VMM domain. The VMM domain helps ACI to connect to datacenter hypervisors like VMware Exsi, Hyper-V etc.

ACI uses Virtual Machine Manager (VMM) domain profiles for communication between virtual machine controllers and the ACI fabric.

A VMM domain helps the ACI infrastructure to send traffic to leaf switches by using POOL of VLANS or VXLAN. For this VLAN pool should be dynamic configured, to allow APIC to allocate the VLANs to EPGs and port groups as needed. VLAN pool can be dynamic or static in nature. Finally VMM domain is associated to AAEP and a Policy group.

The Virtual Machine Manager domain profile helps in grouping VM controllers together. Within this are two components: the credential for connecting to the VM controller, and the controller, which specifies how to connect to the VM controller.

The EPG association allows the APIC to push endpoint groups into the VM controller as port groups and also permits the EPG to span across several VMM domains.

The attachable entity profile association associates a VMM domain to the physical network. Here, we use an attachable entity profile (AEP), which is a network interface template, to set policies on leaf switch ports.

Finally, the VLAN pool association specifies the VLAN ID, or range of IDs, for encapsulation.

Following are the summery steps which APIC uses to integrate with vSphere:

Registering VMM Domain

  • Register APIC to VMware vCenter (Create VMM Domain):
  • Create vCenter Credentials:
  • Create vCenter Server Object:
  • Verifying APIC Connection to vCenter Server:

Adding ESXi Hosts to APIC DVS

  • Add ESXi Hosts to APIC DVS

Associating EPGs to the vCenter Domain

  • Associating vCenter Domain to Application Server EPG
  • Associating vCenter Domain to Database Server EPG
  • Associating vCenter Domain to Web Server EPG:

Associating VM to EPG Port-Groups

  • Map VMs to EPG Port-‐Groups:

The Attachable Access Entity Profile (AAEP):

Creating Attachable Access Entity Profile

LAB:

The Following task will be completed.

Register APIC to VMware vCenter Server. This will create a Distributed Virtual Switch inside VMware’s Network  construct and Verify APIC DVS has been created and connection between APIC and vCenter Server is established

  • Add ESXi Hosts to APIC DVS
  • Associating vCenter Domain to Application Server EPG
  • Associating vCenter Domain to Database Server EPG
  • Associating vCenter Domain to Web Server EPG:
  • Map VMs to EPG Port-‐Groups:
  • Creating Attachable Access Entity Profile and associate it .

Physical Topology:
