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

10. 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. ESXCLI establishes a standard with an extensible framework.
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

15. 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.

16. 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.

17. 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. 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.

28. How Does A User Plan an ESX to ESXi migration?
Visit the ESX and ESXi Info Center
Start testing ESXi
If you’ve not already deployed, there’s no better time than the present
Ensure 3rd party solutions used by your customers are ESXi Ready
Monitoring, backup, management, etc. Most already are.
Bid farewell to agents!
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, …
Plan an ESXi migration as part of vSphere upgrade
Testing of ESXi architecture can be incorporated into overall vSphere testing

29. ESXi and ESX Info Center
All Resources in One Centralized Location

30. 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

31. 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
Confidential

37. VAAI – Introduction vStorage API for Array Integration = VAAI

38. Introducing VAAI Thin Provisioning
What are the driving factors behind VAAI Thin Provisioning?
Provisioning new LUNs to a vSphere environment (cluster) is complicated.
Often requires involvement from multiple people, creating delays in the provisioning process
Strategic Goal:
We want to make the act of physical storage provisioning in a vSphere environment extremely rare.
LUNs should be extended across a large address space and able to handle any VM workload.
VAAI TP features include:
Dead space reclamation.
Monitoring of the space.
vSphere 5.0 introduces multiple VAAI enhancements for environments using Array based Thin Provisioning capabilities. Historically the two major challenges of thin provisioned LUNs have been the reclamation of dead space and the challenges around monitoring space usage. Dead space reclamation offers the ability to reclaim blocks of a thin provisioned LUN on the array when a virtual disk is deleted or migrated to a different datastore by for example Storage DRS.

39. 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.
ESXi 5.0 uses a standard SCSI command for dead space reclamation.

Capturing VM storage SLA requirements
Mapping to the storage with the right characteristics and spare space

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

43. So What Does It Look Like? Provisioning…

44. 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.

48. 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.

51. 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.

52. VM Storage Profile Compliance
Policy Compliance is visible from the Virtual Machine Summary tab.

54. 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.

55. 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.
