Agenda: vSphere 5.0 Platform • ESXi • ESXi CLI • ESXi Firewall • Image Builder • Auto Deploy • vSphere Update Manager • Platform Enhancements

Most Trusted ESXi Convergence 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.” Source: Gartner, August 2010

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

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 3. ‘vicfg’ used for remote CLI only

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. Ruleset Enabled AllowedIP

Composition of an ESXi Image Plug-inComponents CoreHypervisor CIMProviders Drivers

ESXi Image Deployment • Challenges • Standard ESXi image from VMware download site is sometimes limited • Doesn’t have all drivers or CIM providers for specific hardware • Doesn’t contain vendor specific plug-in components ? Missing CIMprovider Missing driver • StandardESXi ISO • Base providers • Base drivers

Describing ESXi Components • VIB • “VMware Infrastructure Bundle”(VIB) • Software packaging format used for ESXi • Often referred to as a “Software Package” • Used for all components • ESXi Base Image • Drivers • CIM providers • Other components • Can specify relationship with other VIBs • VIBs that it depends on • VIBs that it conflicts with

Managing Customized ESXi Images • Image Builder: a set of command line utilities for… • Creating and managing image profiles • Building ESXi customized boot images, e.g. • Installable ISO • Bundle suitable for PXE installation or Flash • Initial version is based on PowerCLI • Snap-in component bundled as part of VMware’s PowerCLI tools • Depot • A repository containing • Image profiles • VIBs • Can have multiple depots, with two types • On a web server • Encapsulated in a .ZIP file

Auto Deploy Overview vCenter Server with Auto Deploy • Deploy and patch vSphere hosts in minutes using a new “on the fly” model • Coordination with vSphere Host Profiles vSphere vSphere Image Profiles Host Profiles Benefits • Rapid provisioning: initial deployment and patching of hosts • Centralized host and image management • Reduce manual deployment and patch processes vSphere vSphere

Auto Deploy Components

Agenda: vSphere 5.0 Platform • ESXi • ESXi CLI • ESXi Firewall • Image Builder • AutoDeploy • vSphere Update Manager • Platform Enhancements

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

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 Confidential

Agenda: vStorage – What’s New • Introduction • VMFS-5 • vStorage API for Array Integration • Storage vMotion • Storage I/O Control • Storage DRS • VMware API for Storage Awareness • Profile Driven Storage • FCoE – Fibre Channel over Ethernet

Introduction to VMFS-5 • 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 Versus VMFS-3 Feature Comparison

VMFS-3 to VMFS-5 Upgrade • 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. • The upgrade is non-disruptive.

Agenda: vStorage – What’s New • Introduction • VMFS-5 • vStorage API for Array Integration • Storage DRS • Storage I/O Control • VMware API for Storage Awareness • Profile Driven Storage • FCoE – Fibre Channel over Ethernet

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. • Support for NAS! Application VI-3 Hypervisor Non-VAAI Fabric Array VAAI LUN02 LUN01

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. vSphere VMFS volume A VMFS volume B

Storage DRS Overview • Group “like” datastores in a datastore cluster. • Initial placement of VMs/VMDKs • Datastore maintenance mode • Space and I/O load balancing • Affinity and anti-affinity rules Affinity Storage vMotion overloaded Benefits • Scalable storage management • Reduce time for VM provisioning • Eliminate VM downtime for storage maintenance • Automated Out of space avoidance • Automated I/O bottleneck avoidance DatastoreCluster

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.

Performance Guarantees – Network and Storage I/O Control Overview 3. w/ I/O controls, can give VIP VMs preferential access 2. Other VMs are starved for resources 1. VM requests more resources • Set up SLAs for use of storage and network resources • Added per virtual machine settings for Network I/O Control • Added NFS support for Storage I/O Control Benefits • Eliminate the “noisy neighbor” problem • More granular SLA settings for network traffic • Extend Storage SLAs to more VMs

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.

Profile-Driven Storage Overview • Tier storage based on performance or SLA characteristics • View a list of all compliant storage resources High IO Throughput Tier 1 Tier 2 Tier 3 Benefits • Utilize the correct storage resources every time (no mistakes) • Help IT personnel that may not be as familiar with storage characteristics align with business and application goals • 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.
