(Trying to) Upgrade memory in ESXi server
No comments on (Trying to) Upgrade memory in ESXi serverMy 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
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…

Power Policy Settings in vSphere 4.1
The new Power Policy Settings in ESXi 4.1 Since the upgrade to VMWare’s ESxi 4.1, I have been curious as to how the newly added power policy settings would affect both system power usage and relative performance. 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
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
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…

Setting up an NFS share to receive ESXi 4.1 VM Backups
Introduction All the datastores on my ESXi box are local currently. In order for me to effectively back up virtual machines, an external datastore was needed. I chose to use Network File System (NFS). None of my virtual machines are mission critical but I do have several that would require some effort to reinstall and…

Enable Tech Support Mode on ESXi 4.1
Tech Support Mode Back when I first installed VMware’s ESXi on my machine, the method for enabling SSH on it required you to have physical access to the machine so you could view/interact with the console. You had to see the output from the ESXi Server. There were six steps. After I upgraded to ESXi…

Upgrading from ESXi 4.0 to 4.1
Introduction In July VMware released a new version of vSphere client and ESXi. I finally got around to seeing what is new in 4.1. Many of the new or enhanced features either did not impact me, or required vCenter (read: $$$$). However, there were some excellent features that did catch my eye: Performance and Scalability…
