- 6. What is Auto Deploy
• New host deployment method introduced in vSphere 5.0
• Based on PXE Boot
• Works with Image Builder, vCenter Server, and Host Profiles
• How it works:
•PXE boot the server
•ESXi image profile loaded into host memory via Auto Deploy Server
•Configuration applied using Answer File / Host Profile
•Host placed/connected in vCenter
• Benefits
•No boot disk
•Quickly and easily deploy large numbers of ESXi hosts
•Share a standard ESXi image across many hosts
•Host image decoupled from the physical server
• Recover host w/out recovering hardware or having to restore from backup

- 8. vSphere HA Primary Components
Every host runs an agent
ESX 01 ESX 03
Referred to as ‘FDM’ or Fault Domain Manger
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
There is no more Primary/Secondary concept with
vSphere HA
ESX 02 ESX 04

- 9. vCenter Communications
VC communicates with the Master primarily
Once a Master is elected and contacts vCenter, vCenter
sends a compatibility list to the Master. The Master
saves this on a local disk, then pushes it out to the other
hosts in the cluster. ESX 01 ESX 03
vCenter also communicates with the Master to update ESX 01 ESX 03
changes to VM states and configuration information.
vCenter may communicate to the Slaves in certain
situations, such as:
• Scanning for a existing Master
• If the Master states that it cannot reach a
Slave. In this case, vCenter will try to
contact the Slave to determine why. ESX 02 ESX 04
ESX 02 ESX 04
• When powering on a FT Secondary VM
• When host is reported isolated or
partitioned.

- 10. Storage Level Communications
One of the most exciting new features of vSphere HA is
its ability to use a storage subsystem for
communication.
The datastores used for this are referred to as ESX 01 ESX 03
‘Heartbeat Datastores’.
This provides for increased communication
redundancy.
Heartbeat datastores are used as a communication
channel only when the management network is lost
- such as in the case of isolation or network
partitioning.

- 19. Storage vMotion - Introduction
In vSphere 5.0, a number of new enhancements were made to Storage
vMotion.
Storage vMotion will work with Virtual Machines that have snapshots,
which means coexistence with other VMware products & features such as
VCB, VDR & HBR.
Storage vMotion will support the relocation of linked clones.
Storage vMotion has a new use case – Storage DRS – which use Storage
vMotion for Storage Maintenance Mode & Storage Load Balancing (Space
or Performance).
