Configure Syslog
Published by Thomas Franke on 07/20/2014 | 0 Comments | 129 Views

Using a Syslog server with your ESXi hosts can save you a lot of time in troubleshooting because all logs are written to a central location. It’s even more important if the boot devices of your hosts are either non-redundant or non-local, because in case of a boot device failure, your host will stop writing logs at all.

Scripting ESXi Advanced Settings
Published by Thomas Franke on 07/03/2014 | 0 Comments | 221 Views

Working with ESXi advanced settings is a common administrative task. If only one host is affected, you’ll probably use the vSphere client to do this. But if you want to process more than one host, using PowerCLI can save you a lot of time.

This post shows how to check or modify these settings by PowerCLI scipts.

The first step in automating tasks with VMware PowerCLI is to open a connection to an ESXi host or vCenter server. This post shows how to do that and a few things you should be aware of.

Book review "vSphere Resource Managemement Essentials"
Published by Thomas Franke on 05/16/2014 | 0 Comments | 645 Views

I just read the book VMware vSphere Resource Management Essentials. Here is what I think about it.

With only 112 pages from cover to cover, the book is rather short. It’s devided into four chapters, each with a different focus. The information is mostly based on vSphere 5.1 and at times on vSphere 5.5.

Howto build a vSphere 5.5 Test Environment 13: Testing vSphere Features
Published by Thomas Franke on 12/16/2013 | 0 Comments | 2,012 Views

We completed the installation of our test environment on the previous part of this workshop. Today we are going to test some interesting vSphere features. But first create a virtual guest machine and install an operating system of your choise and the VMware Tools. Use an iSCSI volume to store the VM and use thin-provisioning to save storage space.

I use a VM with 2 vCPUs, 2 GB RAM, 40 GB HDD, and Windows Server 2012 R2 Standard Evaluation (with GUI). The creation and installation of VM, operating system and VMware Tools were done in less than 10 minutes. That's even better than with many discarded PC or server hardware I used to run test systems on a few years ago. Virtualization really rocks! Smiley

Howto build a vSphere 5.5 Test Environment 12: iSCSI Storage
Published by Thomas Franke on 11/24/2013 | 0 Comments | 2,516 Views

This part of the workshop is about shared storage. We'll need that to use features like vMotion, HA or DRS. I tested several storage products in the past, e. g. FreeNAS, OpenFiler, and Microsoft Storage Server, but with middle-rate results at best. Finally I stubled upon the "Open-E Data Storage Software" - and keep using it since then. Some of the reasons are:

  • It's a full-blown enterprise product that is used by several manufacures of SAN appiances.
  • It supports many storage services, e. g. NFS, SMB/CIFS, FTP, and iSCSI, and a lot of enterprise features.
