VCAP-DCV Deploy Objective 3.3

Home / blueprint / VCAP-DCV Deploy Objective 3.3

In this post we will continue to discuss VMware networking and now it time for scale a vSphere 6.x network implementation

Here are the objectives from the blueprint that i am going to cover:

  • Configure appropriate NIC teaming failover type and related physical network settings
  • Determine and apply failover settings according to a deployment plan
  • Configure and manage network I/O control 3
  • Determine and configure vDS port binding settings according a deployment plan

Lab Setup:

Using VMware workstation:

  • Microsoft Servers 2012R2 for Services (DNS , DHCP, etc…)
  • installed esx0
  • Installed VCSA

 Documents used:

  • vSphere 6 Networking Guide
  • VMware KB 1022312

 

Configure appropriate NIC teaming failover type and related physical network settings and Determine and apply failover settings according to a deployment plan:

Load balancing algos from vSphere networking guide.

Configuration :

NICteam1

When you use explicit failover order you can move the uplinks to a standby mode

NICteam3

Configure and manage network I/O control 3: (From my previous VCP post)

With Network I/O Control version 3 you will be able to reserve bandwidth for system traffic based on the capacity of the physical adapters on a host.Network I/O Control version 3 provisions bandwidth to the network adapters of virtual machines by using constructs of shares, reservation and limit.

We can use Network I/O Control on vDS to configure bandwidth allocation for the traffic for the following vSphere features:

  • Management
  • Fault Tolerance
  • iSCSI
  • NFS
  • Virtual SAN
  • vMotion
  • vSphere Replication
  • vSphere Data Protection Backup
  • Virtual machines

 

nioc1

Enable/Disable Network I/O Control : Network I/O control is enabled by default , so see the setting right click on your vDS and than click setting and then edit setting

NIOC

Configure NIOC shares/limits based on VM requirements: To configure NIOC shares/limits for VM or to any other traffic type you can look at the vDS resource allocation tab and click on the desire traffic type , in this case the VM’s, right click on the VM traffic and click edit , by default you can see that VM has High share size and have no limits.

Monitor Network I/O Control:To monitor the NIOC setting we will look at the vDS >>manage>> resource allocation under system traffic

NIOC_mon

 

Determine and configure vDS port binding settings according a deployment plan:

These three different types of port binding determine when ports in a port group are assigned to virtual machines:

  • Static binding: Assign a port to a virtual machine when the virtual machine connects to the distributed port group.
  • Dynamic binding: DEPRECATED since ESXi 5.0.
  • Ephemeral: No port binding. When the virtual machine powers off or the NIC of the virtual machine is disconnected, the port is deleted.

Configuration:
