Initial Setup#25

Initial Setup

Just boot an ESXi host???#However there is no ESXi Image associated with the Host and no rules created containing an Image Profile to allow the host to boot from and ESXi image. This screen will sleep for 5 minutes and will try to reboot again. This is a neat feature where the Host will continuously try to reboot if by some chance that the TFTP and DHCP server were offline for some quick maintenance.

26Get-ExecutionPolicy It should return the following

If it does not return Unrestricted then we can set the execution policy to be Unrestricted with the following command.

Let now check what PowerShell Snap-ins are loaded. We do this with the Get-PSSnapin cmdlet ( command ) At the command prompt type the following: Get-PSSnapin

Initial Setup

#27The last 3 PSSnap-ins are of interest to us.

VMware.VimAutomation.License - This Windows Powershell snap-in contains cmdlets for managing License components.

VMware.DeployAutomation - Cmdlets for Rule-Based-Deployment

VMware.ImageBuilder - This Windows PowerShell snap-in contains VMware ESXi Image Builder cmdlets used to generate custom images .

Initial Setup#28

Initial Setup#29We will now define a rule in which ESXi 5.0 hosts will be assigned to an Image Profile.

New-DeployRule -Name ForAllHosts -Item $ip[1] -AllHosts

You will see this list continue as it uploads the remaining driversto the Auto Deploy cache.

Initial Setup#PowerCLI C:\> Connect-VIServer 192.168.1.20PowerCLI C:\> Add-EsxSoftwareDepot C:\ESXiImages\ESXi-Image1.zipPowerCLI C:\> New-DeployRule --Name Host-Group1 --Item Image1-Profile --Patternipv4 192.168.1.30 - 192.168.1.50PowerCLI C:\> Add-DeployRUle Host-Group130We can see the rule name ForAllHosts and the Image Profile that was used. To see what rules have been created, we can use the following command:

Get-DeployRule We now need to add the rule to a working ruleSet. We use the following command. Add-DeployRule -deployRule ForAllHosts

To list the rules in a ruleset Get-DeployRuleSet

Initial Setup#31Using an Answer File, administrators can configure host-specific settings to be used in conjunction with the common settings in the Host Profile,avoiding the need to type in any host-specific parameters.

This feature enables the use of Host Profiles to fully configure a host during an automated deployment.

Host Profiles now has support for a greatly expanded set of configurations, including:

vSphere 5

vCenter Site Recovery ManagervCenter OperationsHigh Performance Resource Control, Pooling and SchedulingVirtualized Securityand Edge FunctionsPolicy, Reporting, Self-Service Monitoring and Management Business Continuity#Cloud computing represents a new architectural approach to IT service delivery. At VMware, we are committed to this new approach, and delivering our customers the full capability in an integrated, cohesive solution stack:It all starts on the industrys most robust cloud infrastructure platform, vSphere. Proven the world over, vSphere 5 brings a new virtual, architectural approach to pooling all datacenter resources CPU, Memory, Storage, Networking, creating a seamless fabric of capacity.This new architectural approach enables us to design efficient, low-cost business continuity solutions, which comes with vCenter Site Recovery Manager. Businesses are able to protect a much broader set of the IT portfolio, than was previously cost-effective to support.We are delivering a new class of cloud operational management with vCenter Operations, which leverages patented analytics to discover, monitor, and analyze system behavior in order to support continuous optimization of the infrastructure, even providing predictive analysis of potential problem areas. Likewise, we have pioneered a new virtual approach to security, that is designed for supporting workload portability thoughout and across datacenters.Finally, vCloud Director provides a meta-organizational layer to simplify management of resources based on policies, enabling self-service, reporting and chargeback functions.

Together, this collection of product offerings makes up the industrys first Cloud Infrastructure Suite.

VMware vCloud = Enterprise Hybrid Cloud#The real value in cloud computing is when all boundaries are flexible, to enable cross-cloud federation and coordination. This is what gives customers maximum choice and flexibility in how to streamline costs and improve agility. Our belief is that cloud computing implies a ubiquitous model for interoperability between multiple clouds, both within and outside the enterprise. We refer to this as Open Cloud Computing, which we are fully committed to.

This is why VMware is working with so many public cloud service providers, as part of our vCloud program, to create compatible cloud environments for application mobility.

In particular, we are working with a handful of service providers to create a secure, enterprise-class cloud service, that uses a common service-level management model based on vCloud Director, and a common security model based on vShield, to extend the trust boundary of the enterprise into these public cloud services, and enable the safe, secure mobility of application workloads between the environments.

This class of service is referred to as the VMware vCloud Datacenter Service, and ensures a common platform, management model, and security model, to create the ultimate secure hybrid cloud environment.

With vCloud, customers get to ultimately choose where IT services will operate, and who will operate them, in order to optimize their unique business situation. This is what Your Cloud is all about.51

#vCloud Datacenter Services represents a global network of public cloud partners, providing maximum choice for businesses around the world. In addition, we are working with our partners to create a common way of coordinating across partners within one service contract, in order to support the global rollout of cloud services for customers, without the complexity of dealing with multiple service providers. Expect to see more on this in 2012.Questions?
