What is Auto Deploy

6

• 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 backup11.04.2023 © 2012 ttec computer B.V. / transtec AG

vSphere HA Primary Components

8

Every host runs an agent Referred to as ‘FDM’ or Fault Domain Manger One of the agents within the cluster is chosen to

assume the role of the MasterThere 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

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.

vCenter also communicates with the Master to update 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.

• When powering on a FT Secondary VM

• When host is reported isolated or partitioned.

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 ‘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.



Networking Section03

New Networking Features

11.04.2023 © 2010 transtec AG 12

• Two broad categories of features

• Network Discovery and Visibility/Monitoring features• LLDP• NetFlow• Port Mirror

• IO Consolidation (10 Gig) related features • New traffic types

• User Defined Network Resource Pool ( VM traffic )• Host Based Replication traffic

• 802.1p Tagging (QoS)

• TCP IP stack improvement• Vmknics will see following improvement

• Higher throughput with small messages• Better IOPs scaling for iSCSI traffic

Network I/O Control Enhancements – User-defined Network RP



vStorageWhat’s New in vStorage03

Introduction to VMFS-5

15

• Enhanced Scalability• Increase the size limits of the filesystem & support much larger single extent

VMFS-5 volumes.

• Support for single extent 64TB Datastores

Better Performance Uses VAAI locking mechanism with more tasks

Easier to manage and less overhead Space reclamation on thin provisioned LUNs Smaller sub blocks Unified Block size


VMFS-5 vs VMFS-3 Feature comparison

16

Feature VMFS-3 VMFS-5

2TB+ VMFS Volumes Yes (using extents)

Yes

Support for 2TB+ Physical RDMs No Yes

Unified Block size (1MB) No Yes

Atomic Test & Set Enhancements(part of VAAI, locking mechanism)

No Yes

Sub-blocks for space efficiency 64KB (max ~3k) 8KB (max ~30k)

Small file support No 1KB


VMFS-3 to VMFS-5 Upgrade

11.04.2023 © 2010 transtec AG 17

• The Upgrade to VMFS-5 is clearly displayed in the vSphere Client under Configuration -> Storage view.

• It is also displayed in the Datastores -> Configuration view.

• Non-disruptive upgrades.

VAAI - Introduction

11.04.2023 © 2010 transtec AG 18

• vStorage API for Array Integration = VAAI

• VAAI’s main purpose is to leverage array capabilities

• Offloading tasks to reduce overhead• Benefit from enhanced mechanisms arrays

• The “traditional” VAAI primitives have been improved

• We have introduced multiple new primitives

• Support for NAS!

Storage vMotion - Introduction

19

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).
