Recreating a vmdk descriptor file with vmkfstools

Categories:

vHersey, VMware

by

A VMware virtual machine disk is made up of two files: the .vmdk file and the -flat.vmdk file. The .vmdk file is the descriptor file and the -flat.vmdk file contains the data.

Jumbo Frames – Make sure it is setup end-to-end.

Categories:

DCA, Storage, VCP6, vHersey, VMware

by

Jumbo Frames must be configured correctly end-to-end. This means on the vSwitch, vmkernel interfaces, physical switches, and endpoints. The vmkping command can be used to test a vmkernel interface for proper configuration of Jumbo Frames.

This post is not about virtualization, my home lab, or technology. Going a little low tech here to share a DIY project I did over the weekend, a mobile garage workbench using some free plans I found over at Shanty2Chic.com.

Using vSphere HA to Protect vCenter

Categories:

vHersey, VMware

by

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

Categories:

vHersey, VITA, VMware

by

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.

Checking VMs for SimpliVity Storage HA

Categories:

SimpliVity, Storage

by

When performing maintenance, upgrades, etc, on a SimpliVity host it is important to verify SimpliVity VMs are in a safe Storage HA state. A safe Storage HA state, or Storage HA equal to Yes, means the virtual machine’s data is fully synchronized and protected in the SimpliVity cluster.

SimpliVity, Storage, vHersey

by

This is a quick script, SVT-Fed-Capactiy.ps1, I put together using Powershell and the SimpliVity REST API to report available, free, and used capacity information for OmniStack Clusters in a SimpliVity Federation, and the OmniStack hosts in each Cluster.
