Climate change and what as a citrix admin can do to help! – part 1

Don’t get me wrong, i am sure my carbon footprint is pretty bad, I would like to think I recycle what i can and do my “bit” but certainly could do more. From delving into this piece it got me thinking what can I do to help from a work perspective? well with citrix there is a loottt that can be done.

Researching this piece was intrigued even on the footprint one uses up doing general browsing, nice piece on it:

Take a Dell r720 – a pretty standard piece of server kit.

On reviewing power consumption for it roughly estimate box should cause 1000 Euro over 4 years in terms of electrical consumption. Other piece of course to factor in is all the cooling costs that come with it and savings that can be accrued there.

So from a citrix perspective what options is there to reduce our footprint:

  1. For XenDesktop straightforward Windows 7 / 10 VDI users there is the default power consumption – see under the “power manage the machines in a delivery group” section

For RDS workloads previously SmartScale could assist with this but this is being replaced with a new feature called AutoScale.

Autoscale and how to setup

One interesting element about this Autoscale blog article was there no mention of the environmental benefits the product provided:

On top of the virtual machine pieces above of course it is incumbent on setting your power management on at the hypervisor level to ensure your hosts are switching off when not in use (of course let your monitoring teams know to be “elastic” with their up/down monitoring)

VSphere uses whats called distributed power management(DPM), citrix hypervisor and microsoft hyper-v come with their own variants but worth examining.

More and more on reviewing our usages only feel am tipping the iceberg in terms of what we can do to as admins in this field. Next article will discuss VM sprawl in general, its effect on the environment and steps we can do to mitigate it. Particularly with a view to weekends and all the workloads that are running then, always take the example of buses – locally here our Sunday bus service probably runs half the buses a normal weekday would run – now do you think all them buses are left with their engine running in the depot all day on the Sunday? think not!
