ESXi Convergence
Most Trusted
Overview
 vSphere 5.0 will utilize the ESXi
hypervisor exclusively
 ESXi is the gold standard for hypervisors
vSphere ESXi
Benefits
 Thin architecture
 Smaller security footprint
 Streamlined deployment and
configuration
 Simplified patching and updating model
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.”

ESXi Command Line
 Why a new ESXi CLI tool?
• Console CLI and remote vCLI are different
• Need to learn multiple CLIs
• Local commands don’t work remote, remote commands don’t 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

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 on
IP address/Subnet Mask.
 Management
• The GUI for configuring the firewall on ESXi 5.0 is similar to that used with the
classic 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 firewall
settings preserved.
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 for
each service & the Allowed IP List for each service.
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.
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 you’ve not already deployed, there’s 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
ESXi and ESX Info Center
All Resources in One Centralized Location
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 that’s 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

VAAI – Introduction
 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 mechanisms
 The “traditional” VAAI primitives have been improved.
 We have introduced multiple new primitives.

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 system
via VAAI & storage system reclaims the dead blocks.
• Storage vMotion, VM deletion
and swap file deletion can trigger
the thin LUN to free some
physical space.
vSphere
• ESXi 5.0 uses a standard SCSI
command for dead space reclamation.

 Scalable storage management
 Reduce time for VM provisioning
 Eliminate VM downtime for storage
maintenance
 Automated Out of space avoidance
 Automated I/O bottleneck avoidance
SDRS Scheduling
SDRS allows you to create a schedule to change its settings.
This can be useful for scenarios where you don’t want VMs to migrate between datastore
or when I/O latency might rise, giving false negatives, e.g. during VM backups.
So What Does It Look Like? Provisioning…
So What Does It Look Like? Load Balancing.
 The Storage DRS tab will show “utilization before” and “after”.
 There’s always the option to override the recommendations.

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 that
enables Profile-driven Storage.
•
Another example is that it provides array internal information that helps
several Storage DRS use cases to work optimally with various arrays.

 Improve storage utilization and
efficiencies
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.
VM Storage Profile Compliance
 Policy Compliance is visible from the Virtual Machine
Summary tab.

FCoE – Fibre Channel over Ethernet
Software FCoE Adapters (1 of 2)
 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 support
partial FCoE offload.
 Unlike the hardware FCoE adapter, the software adapter needs to
be activated, similar to Software iSCSI.
Software FCoE Adapters (2 of 2)
 Once the Software FCoE is enabled, a new adapter is created, and
discovery of devices can now take place.
