Ultimate automation guide to deploying VCSA 6.0 Part 3: Replicated Platform Service Controller Node

03.03.2015 by William Lam // 12 Comments

In this article, I will share alternative methods of deploying replicated Platform Services Controller Node (PSCs) using the VCSA 6.0 appliance. Take a look at the various deployment methods below and their respective instructions for more details. If you are deploying using one of the scripts below, you will need to extract the contents of the VCSA ISO. If you are deploying to Workstation/Fusion, you will need to extract the VCSA ISO and add the .ova extension to the following file VMware-VCSA-all-6.0.0-2562643->vcsa->vmware-vcsa before deploying.

Disclaimer: Though these alternative deployment options work, they are however not officially supported by VMware. Please use at your own risk.

Deploying to an existing vCenter Server using ovftool (shell script)

I have created a shell script called deploy_vcsa6_replicated_psc_to_vc.sh which requires using ovftool 4.1 (included in the VCSA ISO) to specify the appropriate OVF "guestinfo" properties for a replicated PSC deployment. You will need to edit the script and modify several variables based on your environment.

Here is an example of executing the script:

vcsa-6.0-replicated-platform-service-controller-node-deployment

Deploying to an ESXi host using ovftool (shell script)

I have created a shell script called deploy_vcsa6_replicated_psc_to_esxi.sh which requires using ovftool 4.0 or greater to specify the appropriate OVF "guestinfo" properties for a replicated PSC deployment. You will need to edit the script and modify several variables based on your environment. The behavior of this script is similar to the one above, except you are deploying directly to an ESXi host.

Deploying to an existing vCenter Server using ovftool (PowerCLI)

I have created a PowerCLI script called Deployment-PSC-Replication.ps1 which uses ovftool and specifies the appropriate OVF "guestinfo" properties for a replicated PSC deployment. You will need to edit the script and modify several variables based on your environment.

Deploying to VMware Fusion & Workstation

To properly deploy the new VCSA 6.0, the proper OVF properties MUST be set prior to the booting of the VM. Since VMware Fusion and Workstation do not support OVF properties, you will need to manually deploy the VCSA, but not power it on. Once the deployment has finished, you will need to add the following entries to the VCSA's VMX file and replace it with your environment settings. Once you have saved your changes, you can then power on the VM and the configurations will then be read into the VM for initial setup.

guestinfo.cis.deployment.node.type = "infrastructure"
guestinfo.cis.vmdir.domain-name = "vghetto.local"
guestinfo.cis.vmdir.site-name = "vghetto"
guestinfo.cis.vmdir.password = "VMware1!"
guestinfo.cis.vmdir.first-instance = "false"
guestinfo.cis.vmdir.replication-partner-hostname = "192.168.1.50"
guestinfo.cis.appliance.net.addr.family = "ipv4"
guestinfo.cis.appliance.net.addr = "192.168.1.63"
guestinfo.cis.appliance.net.pnid = "192.168.1.63"
guestinfo.cis.appliance.net.prefix = "24"
guestinfo.cis.appliance.net.mode = "static"
guestinfo.cis.appliance.net.dns.servers = "192.1681.1"
guestinfo.cis.appliance.net.gateway = "192.168.1.1"
guestinfo.cis.appliance.root.passwd = "VMware1!"
guestinfo.cis.appliance.ssh.enabled = "true"

Deploying using new supported scripted install (bonus)

As mentioned earlier, there is also a new scripted installer included inside of the VMware-VCSA ISO under /vcsa-cli-installer which supports Windows, Mac OS X and Linux, but must be connected directly to an ESXi host. There are several templates that are also included within the /vcsa-cli-installer/templates. I thought as a bonus I would also share the template I have been using to deploy replicated PSC instances using a static IP Address which some of you may find useful.

            "system.name":"192.168.1.51"
        }
    }
}

The use the scripted installer, you just need to change into the appropriate OS platform directory (win32,mac or lin64) and there should be a binary called vcsa-deploy. To use this template, you just need to save the JSON to a file and then specify that as the first argument to vcsa-deploy utility.

Here is an example of deploying a PSC using the vcsa-deploy scripted installer.

Ultimate automation guide to deploying VCSA 6.0 Part 2: Platform Services Controller Node

02.26.2015 by William Lam // 14 Comments

In this article, I will share alternative methods of deploying the first Platform Services Controller Node (PSCs) using the VCSA 6.0 appliance. If you are interested in deploying additional PSC instances joined to an existing SSO Domain, stay tune for Part 3 where this will be covered. Take a look at the various deployment methods below and their respective instructions for more details. If you are deploying using one of the scripts below, you will need to extract the contents of the VCSA ISO. If you are deploying to Workstation/Fusion, you will need to extract the VCSA ISO and add the .ova extension to the following file VMware-VCSA-all-6.0.0-2562643->vcsa->vmware-vcsa before deploying.

Quick Tip - How to enable memory overcommitment in VMware Fusion?

02.14.2015 by William Lam // 20 Comments

There was an interesting internal thread that I came across yesterday where someone was asking if VMware Fusion supported memory overcommitment like VMware Workstation? In VMware Workstation, memory overcommitment can be adjusted by going to Edit->Preferences->Memory which provides three different options as shown in the screenshot below. This setting specifies the percentage of memory that would be reserved from the physical host memory for each Virtual Machine.

vmware-fusion-memory-overcommit-0
These options map to the following % of host memory reservation:

Option % of Host Memory Reserved Per VM
Fit all virtual machine memory into reserved host RAM 100
Allow some virtual memory to be swapped 50
Allow most virtual memory to be swapped 25

Disclaimer: Be aware, that default safe guards have been put in place to ensure optimal VM performance. If you decide to change these settings and allow memory overcommitment, it can potentially degrade performance of both your VMs as well as host system. Make sure you understand the changes before applying them.

You can also specify a custom value by editing the VMware Workstation configuration file located in: C:\ProgramData\VMware\VMware Workstation\config.ini and modifying or adding the following property:

prefvmx.minVmMemPct = P

where P is the percentage of configured VM memory that should fit into the host memory. The smallest value that P can be is 1. Below is a screenshot of a 32GB VM running on a Macbook Air with latest version of Fusion (8.5.3) which only has 8GB of physical memory and the value that I had used for this demonstration is 1.

Going back to VMware Fusion, memory overcommitment is also possible but the option to configure it is not available in the VMware Fusion UI. You will need to add the above setting into the VMware Fusion configuration file located in /Library/Preferences/VMware\ Fusion/config which does not exist by default. You will need to restart Fusion/Workstation for the change to go into effect.

In addition to the change, if you do decide to overcommit your memory, it was also mentioned that you may also want to disable Hard Disk buffering for optimal performance. You can make this change in the Advanced Settings of the the VM as seen in the screenshot below.

vmware-fusion-memory-overcommit-1
You can also just add the following property to the Virtual Machine's VMX configuration file:

hard-disk.hostBuffer = "disabled"

Memory commitment can be a wonderful tool, especially for lab environments. If you combine this with SSD storage and if swapping does occur, the impact may be acceptable so that you can run a few more VMs. Thanks to Regis Duchesne & Jesse Pool for sharing this handy tidbit!
