(Trying to) Upgrade memory in ESXi server

April 13, 2015

My ESXi server has been faithfully serving me for the past five years. As noted previously, it has just 8GB of ram installed (4x2GB). No, you did not misread that; eight gigabytes. This has been fine for my needs as the virtual machines running are not ram-hungry. The 2003 server, vortexbox, Openmediavault and an XubuntuLTS […]


The backup GPT table is not at the end of the disk, as it should be.

I began seeing an error in my vkernel logs in ESXi. The backup GPT table is not at the end of the disk, as it should be. This might mean that another operating system believes the disk is smaller. Fix, by moving the backup to the end (and removing the old backup)? This will also […]


Multiple vCPU encoding performance in ESXi 4.1

October 9, 2010

Background This is a continuation of my post about vSphere 4.1’s new Power Policy settings. This post will look more closely at how adding additional vCPUs to an encoding process can impact its performance, and whether the power settings make that big a difference on a more heavily-loaded system. An excellent document on the vSphere […]

This short post will look at how the various power settings affect my specific setup during idle time, […]


ESXi Windows NFS datastore inactive upon reboot

September 6, 2010

The problem The NFS datastore I recently created to hold the virtual machine backups from my home ESXi server showed as “inactive” upon a recent server reboot. This was unexpected but, after some Googling, definitely not unusual. A second reboot (why not?) still did not restore the connection. I needed to find a proper solution […]


Using ghettoVCB.sh to backup ESXi 4.1 VMs to NFS Datastore

Tags: , ,

Introduction I recently created an NFS datastore on ESXi, linked to a Windows Services for Unix (WSFU) share on my backup, Windows XP machine. The purpose of the datastore was to store virtual machine backups. The next step in the process is to configure ghettoVCB to perform the VM backups. ghettoVCB Details of ghettoVCB can […]
