8. VMware ESXi™ networking features allow the following:
Virtual machines to communicate with other virtual and physical machines
Management of the ESXi host
The 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

9. 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)

10. A virtual switch allows the following connection types:

For the ESXi management network

16. 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

17. Vmotion & DRS
• Relocate running VM from one datastore
to another datastore with zero downtime
Relocate across different storage types•
• Change VM disk format (thick or thin)

19. Protection at Every Level

20. A highly available system is one that is continuously operational for an optimal
length of time.
High Availability
Level of Availability Downtime Per Year
99% 87 hours (3.5 days)
99.9% 8.76 hours
99.99% 52 minutes
99.999% 5 minutes
Which level of virtual
machine availability is
important to you?

21. 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

22. 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.

23. 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
