News and/or announcements about the Practical XenServer site.

The PXS Lab, Version 2.0

We’ve completely re-tooled the PXS Lab using smaller, quieter, and more energy-efficient equipment. This will allow us to keep costs low while keeping the footprint small and stealthy!

The very first PXS Lab:

The PXS Lab, Version 1.0
The very first PXS Lab – Built using first-generation HP Proliant rack-mount servers; HP Procurve switches, and; Cisco routers.

At idle: This “hardware stack” consumed 1.25 kW and required hearing protection when working for extended periods of time!

The new PXS Lab:

The PXS Lab, Version 2.0
Version 2.0 of the PXS Lab – Leaner. Meaner. Cleaner. Built with standard Dell Optiplex workstations; HP Procurve managed switches, and; a pfSense firewall appliance (not pictured).

At idle: This “hardware stack” consumes only 250-275 W of electricity – And it’s so quiet that there’s never any need for hearing protection!

We believe that this design will provide almost all of the same flexibility as the first Lab. But it will be smaller, quieter, and less expensive to operate – $135, annually. Versus $650, annually!

We hope that you’ll follow along with us as we resume our mission to provide Practical Guidance to XenServer Administrators©.

The Tutorial “Bonding Network Interfaces” has Been Replaced

We’ve been working to revise the tutorial “Bonding Network Interfaces” (Scenario #2, Tutorial #2) and we’re excited to announce that the new version of the tutorial is now available for your review!

This version of the tutorial is broken into six parts and replaces both parts of the previous version – Part #1 & Part #2 – but we’ll leave both parts of the previous version accessible for the foreseeable future – for comparison’s sake.

There’s already a forum for discussing this tutorial.

As always: We hope that you’ll find it informative and useful!

A New Tutorial: Bonding Network Interfaces!

We’ve been working hard on the next tutorial – “Bonding Network Interfaces” – but it’s such an enormous topic that we’ve had to split the tutorial into two parts. Today we’re announcing that Part I of the Tutorial “Bonding Network Interfaces” is complete.

Part I will address the details behind bonding. Part II will address the process of configuring bonding.

There’s already a forum for discussing this tutorial.

We hope that you’ll find it informative and useful!

New Format for Code Samples

We’ve reformatted each of the tutorials to strip away some of the extraneous clutter and help the information shine through!

Here, at Practical XenServer, we’re all about presenting the information that XenServer (XS) administrators need in order to work efficiently and effectively from the Command-Line Interface (CLI). So, in order to better serve that goal, we’ve reformatted each of the tutorials to remove as much of the clutter as possible and more effectively present the information in a clear, concise way.

We hope that you’ll agree and we look forward to your comments in the Forums!

A new Scenario – and a new Tutorial!

We’ve decided to skip ahead of Scenario #1 and begin publishing tutorials for Scenario #2.

There were a number of factors that went into the decision but, ultimately, we decided that Scenario #2 addresses a much more practical use-case than Scenario #1 and, therefore, provides more value to more XenServer administrators, and; that it was best to keep moving ahead with publishing tutorials and moving on to Scenario #2 supports that objective. We’ll continue working on Scenario #1 as time permits but, in the mean time, we hope that you’ll support our decision and that you’ll find Tutorial #1 useful.


Improvements & Changes

As we’ve been building-out Practical XenServer (PXS) we’ve not been very tidy – leaving placeholders laying around like construction scraps – but today we’ve taken a step forward in making the site more presentable: All of the miscellaneous stubs (i.e., placeholder pages with no content) have been pruned and – for illustrative purposes only, where there will be important content relatively soon – we’ve replaced the active, dead-end hyperlinks with a notice to readers that the content is “Coming soon!

While this may not be “best practice” we feel that this strikes a good balance: It helps us, as the creators of PXS, visualize how the site will grow and develop, and; it helps you, the reader, understand the direction that we’re working in.

We hope that you agree with us and that you’ll continue to return to PXS to learn more about working efficiently and effectively with XenServer.
