Topics
VMware ESXi™ networking features allow the following:Virtual machines to communicate with other virtual and physical machinesManagement of the ESXi hostThe VMkernel to access IP-based storage and perform VMware vSphere® vMotion® migrations
Failure to properly configure ESXi networking can negatively affect virtual machine management and storage operations.
Importance
A virtual network supports two types of virtual switches:vNetwork standard switches:
Virtual switch configuration for a single host
vNetwork distributed switches:Virtual switches that provide a consistent network configuration for virtual machines
as they migrate across multiple hosts ( DRS , vMotion)

Migration: Moving a virtual machine from one host or datastore to another host or datastore. Types of migrations:
Cold: Migrate a virtual machine that is powered off.Suspended: Migrate a virtual machine that is suspended.vSphere vMotion: Migrate a virtual machine that is powered on.vSphere Storage vMotion: Migrate a virtual machine’s files, while the virtual machine is powered on, to another datastore.
Migrating Virtual Machines
Vmotion & DRS
• Relocate running VM from one datastoreto another datastore with zero downtime
Relocate across different storage types•• Change VM disk format (thick or thin)

Protection at Every Level
A highly available system is one that is continuously operational for an optimal length of time.
High Availability
Level of Availability Downtime Per Year

Which level of virtual machine availability is important to you?
You can use NIC teaming to create a redundant heartbeat network on ESXi hosts.Ports or port groups that are used must be VMkernel ports.
Redundancy Using NIC Teaming
NIC Teaming on an ESXi Host
Redundancy Using Additional Networks
You can also create redundancy by configuring more heartbeat networks:
On each ESXi host, create a second VMkernel port on a separate virtual switch with its own physical adapter.
Redundancy Using Additional ESXI (Hosts)
Every host runs an agent.
••
Referred to as (FDM) or Fault Domain Manager
One of the agents within the cluster is chosen to assume the role of the Master There is only one Master per cluster during normal operations
All other agents assume the role of Slaves
