ESXi Convergence Most Trusted

vSphere ESXi

vSphere 5.0 will utilize the ESXihypervisor exclusively

ESXi is the gold standard for hypervisors

Overview

Benefits

Thin architecture

Smaller security footprint

Streamlined deployment and

configuration

Simplified patching and updating model


10/71

The Gartner Group says

The major benefit of ESXi is the fact that it is more lightweight

under 100MB versus 2GB for VMware ESX with the service

console.

Smaller means fewer patches

It also eliminates the need to manage a separate Linux console(and the Linux skills needed to manage it)

VMware users should put a plan in place to migrate to

ESXi during the next 12 to 18 months.

12/71

ESXi Command Line

Why a new ESXi CLI tool?

Console CLI and remote vCLI are different

Need to learn multiple CLIs

Local commands dont work remote, remote commands dont work locally

Commands evolved from multiple sources using different standards

No formal process for adding or updating commands

Inconsistent output and syntax

Output format changes from command to command

Different commands have different input parameters

Remote CLI limited compared to local CLI

ESXCLI establishes a standard with an extensible framework.

Going forward ESXCLI commands will be backward compatible


13/71

vSphere 5.0 CLI Compatibility

1. esxcfg commands deprecated in 5.0 (replaced with esxcli)

2. esxcli in 4.x is *not* backward compatible with 5.0

ESXi 5.0 Firewall Features

Capabilities

ESXi 5.0 has a new firewall engine which is not based on iptables.

The firewall is service oriented, and is a stateless firewall.

Users have the ability to restrict access to specific services based onIP address/Subnet Mask.

Management

The GUI for configuring the firewall on ESXi 5.0 is similar to that used with theclassic ESX firewall customers familiar with the classic ESX firewall should

not have any difficulty with using the ESXi 5.0 version.

There is a new esxcli interface (esxcfg-firewall is deprecated in ESXi 5.0).

There is Host Profile support for the ESXi 5.0 firewall.

Customers who upgrade from Classic ESX to ESXi 5.0 will have their firewallsettings preserved.


16/71

UI: Security Profile

The ESXi Firewall can be managed via the vSphere client.

Through the Configuration > Security Profile, one can observe the

Enabled Incoming/Outgoing Services, the Opened Port List foreach service & the Allowed IP List for each service.


17/71

UI: Security Profile > Services > Properties

Through the Services Properties, one can configure if a service

should be automatically started.

Services can also be stopped & started on-the-fly.


18/71

UI: Security Profile > Firewall > Properties

In the Firewall properties, one can check or uncheck the checkbox

associated with a service to enable/disable access.

Service name, open ports and status are also displayed.

How Does A User Plan an ESX to ESXi migration?

1. Visit the ESX and ESXi Info Center

2. Start testing ESXi If youve not already deployed, theres no better time than the present

3. Ensure 3rd party solutions used by your customers are ESXi Ready

Monitoring, backup, management, etc. Most already are.

Bid farewell to agents!

4. Familiarize with ESXi remote management options

Transition any scripts or automation that depended on the COS

Powerful off-host scripting and automation using vCLI, PowerCLI,

5. Plan an ESXi migration as part of vSphere upgrade

Testing of ESXi architecture can be incorporated into overall vSphere testing

30/71

ESX to ESXi Migration with VMware Update Manager

Supported Paths

Migration from ESX (Classic) 4.x to ESXi 5.0

For VUM-driven migration, pre-4.x hosts will have to be upgraded to 4.x first

Might be better just to do fresh install of ESXi 5.0

Preservation of Configuration Information

Most standard configurations will be preserved, but not all:

Information thats not applicable to ESXi will not be preserved, e.g.

/etc/yp.conf (no NIS in ESXi)

/etc/sudoers (no sudo in ESXi)

Any additional custom configuration files will not be preserved, e.g.

Any scripts added to /etc/rc.d

Confidential

ESXi Migration and Third-Party Software

Supported components

Upgrade of third-party components limited to

Cisco Nexus 1000v EMC PowerPath

During upgrade, if either of these is detected on starting host

Target ESXi image is checked for presence of these modules

If found, upgrade proceeds

If not found, option provided to override and proceed

Otherwise, halt

All other components

Starting host not checked for other third-party software

Upgrade process will not preserve anything

Up to Admins to take care of replacing

38/71

VAAI Thin Provisioning Dead Space Reclamation

Dead space is previously written blocks that are no longer used

by the VM. For instance after a Storage vMotion.

vSphere conveys block information to storage systemvia VAAI & storage system reclaims the dead blocks.

Storage vMotion, VM deletionand swap file deletion can trigger

the thin LUN to free some

physical space. ESXi 5.0 uses a standard SCSI

command for dead space reclamation.

SDRS Scheduling


41/71

SDRS Scheduling

SDRS allows you to create a schedule to change its settings.

This can be useful for scenarios where you dont want VMs to migrate between datastore

or when I/O latency might rise, giving false negatives, e.g. during VM backups.

What Is vStorage APIs Storage Awareness (VASA)?


47/71

What Is vStorage APIs Storage Awareness (VASA)?

VASA is an Extension of the vSphere Storage APIs, vCenter-based

extensions. It allows storage arrays to integrate with vCenter for

management functionality via server-side plug-ins or Vendor

Providers.

This in turn allows a vCenter administrator to be aware of the

topology, capabilities, and state of the physical storage devices

available to the cluster.

VASA enables several features.

For example it delivers System-defined (array-defined) Capabilities thatenables Profile-driven Storage.

Another example is that it provides array internal information that helpsseveral Storage DRS use cases to work optimally with various arrays.

Selecting a Storage Profile During Provisioning

By selecting a VM Storage Profile, datastores are now split into

Compatible & Incompatible.

The Celerra_NFS datastore is the only datastore which meets the

GOLD Profile requirements i.e. it is the only datastore that has

our user-defined storage capability associated with it.

Software FCoE Adapters (1 of 2)


53/71


A software FCoE adapter is a software code that performs some of

the FCoE processing.

This adapter can be used with a number of NICs that supportpartial FCoE offload.

Unlike the hardware FCoE adapter, the software adapter needs to

be activated, similar to Software iSCSI.

Once the Software FCoE is enabled, a new adapter is created, and
