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
Using VMware workstation:
- Microsoft Servers 2012R2 for Services (DNS , DHCP, etc…)
- installed esx0
- Installed VCSA
- 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.
When you use explicit failover order you can move the uplinks to a standby mode
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:
- Fault Tolerance
- Virtual SAN
- vSphere Replication
- vSphere Data Protection Backup
- Virtual machines
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
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
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.
