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.

Target the vMA for VCSA Backups

One handy new feature available with vSphere 6.5 is the ability to take a supported backup of the vCenter Server Appliance (VCSA) configuration and database. VCSA backups can be transferred to a target using HTTP/S, FTP/S, and SCP. This post walks through backing up the VCSA using SCP to target the vSphere Management Assistant (vMA) to store the backup.

Adding a /workspace Disk to the vSphere Management Assistant (vMA)

The vMA is deployed with a single 3 GB disk with about 1 GB available after deployment. This post walks through adding a disk to the vMA appliance to provide additional storage for scripts, logs, VIBs, iso, backups, etc.

Add an Entry to ESXi /etc/hosts using PowerShell

I was looking for away to easily add an entry to an ESXi host’s /etc/hosts file without using SSH to connect to the host. ESXi has a file management interface which can be accessed with standard GET/PUT operations. I put together a quick example of doing this with PowerShell using Invoke-WebRequest.

Locating SimpliVity Manual Backups

Policy based SimpliVity backups have a retention period defined in the backup policy. When the retention period expires the backup is removed from the system. When a Manual SimpliVity Backup is taken, no retention period is set and the backup will never expire. This post provides some details on how to locate Manual SimpliVity Backups using the vSphere Web Client or the SimpliVity REST API.
