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

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).
