Editor's Notes
- #5 As close as I may be to god – the last one I cannot provide…
- #6 Convergence10Gb
- #8 If you only have an empty rack – with no supporting infrastructure.
- #10 Yes there are companies that do this – such as VCENot everyone can afford a vBlock
- #11 We broke it down into steps, and this is what we gotOf course not everything can be automated – but as much as possible was desired
- #12 Proper automation without an API is really difficult.So we have one for UCS (except the initial setup)Nexus – NopeStorage – Partially – because additional Storage Vendor software is needed
- #13 Have to lay out all the stepsNetwork connectivityFabric InterconnectsUplink Switches
- #14 A set of instructions for the engineer, for basic cabling – with a standard of ports – both on the Uplink switches – and the FI’sBasic VLAN definitionsFC uplinks
- #15 Cisco have a very rich API which allows for the configuration of a full UCS serverAlan Renouf and Eric Williams
- #16 USB Key was the less of two evils – less dependency on external components.Powershell script to create the kickstart files – which accepts input from CSV file.Razor is better for bigger environments
- #17 Static IP’s + Hostnames are not are not possible in razor – so we needed to go around it.
- #18 VM’s were deployed and configured with IP addresses – then vCenter was installed.Time to install vCenter – was less than 10 minutes – automated scripts that put IP’s
- #19 Python scripts – William Lam has a great post – but not suitable – no vCenter at the time of kickstartThe Puppet environment was the preferred choice – because it allows for the definition of a full environment – also the guests as wellvCenter installation could also build the environment
- #20 How could I actually start without attached storage – with local disks – and svMotion after the fact.EMCStorage IntegratorData ONTAP PowerShell Toolkit
- #21 Clone SizeHave to keep it updated.But what if I want the build to be a physical node – or on another cloud / datacenter ?Deploy - always consistentQuickerVery portable – the RHEL ISO is always available…The empty shell VM’s could be create either with PowerCLI or through puppet (cloning only)Razor and Puppet go hand in hand
- #22 Razor already has the tags in place – that is what it does extremely well. Plant these tags as a custom fact and have Puppet apply modules according to the fact discovery.
- #23 The whole process had a large number of steps – and many dependencies. Break it down piece by piece and work you way through the problem.Oracle RAC installation script for example (~1000 lines) and growing.Razor re-write has caused a lot of pain. But a great learning process.Puppet – great tool – very powerful – but not all encompassing.
