  2. Thinking, Building and Scripting Globally Who? What? Why? How?

  3. Who? Julian Wood IT Infrastructure Architect & Blogger www.WoodITWork.com @julian_wood

  4. What? Have a single PowerCLI script to build ESX(i) anywhere in your organisation.

  5. Why? • One script to maintain • One script to execute • Reduce errors • Set a global build standard • Maintain local differences • Remove reliance on COS Scripts • PowerCLI • Move From ESX to ESXi

  6. ESX -> ESXi • vSphere 5 is ESXi only • Service Console to Management Interface • COS Scripts • Disk Partitioning • USB / SD • PXE • Agents • Inventory • Security • Backup • Hardware • Monitoring

  7. Why are build standards important? • Repeatability • Reduce complexity • Champion simplicity • Reduce OpEx • Troubleshooting • Reporting • Automation

  8. Cloud thinking…The way forward! • Not about IT but about the business • Strategy is top down, not bottom up • Moving from Systems to Services • Think big & tackle a piece at a time • It’s bigger than deploying VMs Service Catalogue Standardisation + Process + Automation

  9. Your Cloud Foundation • Hosts • Strategy • Global layout • Make things the same • Try to make different things the same • Hardware • Number of Nics • Global Network plan • Global Storage plan • Accommodate local differences

  10. Your buildWhat’s the same? • Naming Standard • Hardware Vendor • Number of Nics • Console Memory • Partitions • Storage Protocol • Switch Port Numbers • Version + Patches • NTP Servers • Search Domains

  11. Your buildWhat’s different? • IP Addresses • Subnets • Gateways • Clusters • Hardware • DNS Servers • Host Names • Port Groups • Datastores • File Locations

  12. Global LayoutCluster Requirement London Prod Servers Dev Servers Unix BigApp VDI New York Servers VDI Tokyo Servers VDI

  13. Build basics • Build ESX(i) hosts • Blades • 4 x Nics • Directional Traffic • NFS • What’s Unique • Host Name • IP Address • Computing values • IP address / hostname gives you site • Host number can calculate IP info

  14. Build basicsNaming Standards Host Naming Standards = $HostType • WIN Server hosts = <country><site><ESX><number> • Unix Server hosts = <country><site><ESXUX><number> • VDI hosts = <country><site><ESXVDI><number> • jptokesx78 • gblonesxux10 • usnycesxvdi22

  15. Build basicsIP Addresses IP Address = $Site

  16. Let’s get scripting!Connect #Ask for the host to connect to Write-Host"Enter ESX(i) Host FQDN /IP "-ForegroundColorMagenta $vmhost=read-host If ($vmhost-eq"") { Write-Host"No ESX(i) Host Supplied, Exiting"-ForegroundColorRed Exit} Write-Host"Enter ESX(i) host credentials to authenticate"-ForegroundColor ; Magenta $ESXCred=$host.ui.PromptForCredential("ESX(i) credentials", "Please enter the; ESX(i) host user name and password.", "", "") #Connect to the ESX(i) Host $ESXConnect=Connect-VIServer-Server$VMHost-Credential$ESXCred If ($ESXConnect.IsConnected-ne$true){ Write-Host"Cannot connect to ESX(i) Host, Exiting"-ForegroundColorRed Exit} $ESXHost=Get-VMHost
