Using vSphere HA to Protect vCenter

The ability to provide HA protection of the vCenter Server is one of benefit of deploying vCenter as a virtual machine. vCenter is required to configure vSphere HA but once vSphere HA is configured vCenter is NOT required for vSphere HA to protect virtual machines in the cluster, including a virtualized vCenter Server.

Setting up the Weathervane Benchmarking Tool in the Home Lab

Standing up Weathervane in the home lab will provide hands-on for developing skills like creating a template VM, creating a guest customization specification, working with some basic Linux commands, working with an app with multiple tiers, creating a guest customization specification, cloning VMs, and monitoring performance metrics. This post provides an overview of how I set up Weathervane in my home lab, an example of the results generated from the Weathervane runs, and a look at the performance metrics I observed in lab during the Weathervane runs.

Collect Virtual Disk IOPS with PowerCLI

I was messing around with PowerCLI and the real-time statistics to collect the IOPS used by virtual machines/virtual machine disks in my my home lab. Virtual disk performance counters are available in the real-time performance stats but at the default statistics level, Level 1, with the IOPS statistics are not rolled up into the daily, weekly, monthly, or yearly statistics. I put together a PowerCLI script, collect-iops.ps1, to collect the real-time samples.

SimpliVity Custom Backup Scheduling Using the REST API

SimpliVity Backups are Policy-based and VM-Centric. SimpliVity Backup Policies automate the protection of virtual machines in order to meet Recovery Point Objectives (RPO). Full virtual machines or individual files/folders with virtual machines can be quickly restored to the point in time when the backup was taken. This post provides a solution for using the REST API to schedule SimpliVity backups outside of the standard options available when creating backup policy rules.

Automate Backup of the VCSA to the vMA

Recently I did a post on how to Target the vMA for VCSA Backups. This post takes things a step further and automates the backup of the VCSA using a shell script, the vCenter Appliance REST API, and cron on the vMA.
