How to setup Multi-NIC vMotion on a distributed vSwitch

This article provides you an overview of the steps required to setup a Multi-NIC vMotion configuration on an existing distributed Switch with the vSphere 5.1 web client. This article is created to act as reference material for the designing your vMotion network series. Configuring Multi-NIC vMotion is done at two...

IP-Hash versus LBT

vSwitch configuration and load-balancing policy selection are major parts of a virtual infrastructure design. Selecting a load-balancing policy can have impact on the performance of the virtual machine and can introduce additional requirements at the physical network layer. Not only do I spend lots of time discussing the various options...

vSwitch Failback and High Availability

One setting most admins get caught off-guard is vSwitch Failback setting in combination with HA. If the management network vSwitch is configured with Active/Standby NICs and the HA isolation response is set to “Shutdown” VM or “Power-off” VM it is advised to set the vSwitch Failback mode to No. If...

Load Based Teaming

In vSphere 4.1 a new network Load Based Teaming (LBT) algorithm is available on the distributed virtual switch dvPort groups. The option “Route based on physical NIC load” takes the virtual machine network I/O load into account and tries to avoid congestion by dynamically reassigning and balancing the virtual switch...
