As pressure mounts to improve environmental awareness, reduce carbon footprint and comply with government regulations your IT systems and services are far from exempt.
Thinking about the environment does not mean additional expense; in most cases it can save you money at the same time.
A few quick wins are:
- Virtualisation – Consolidate multiple server workloads onto fewer, reducing the power used and heat produced in most cases.
- Replace servers over 3 years old with newer more energy efficient systems if you have them on an annual maintenance contract it is likely to also save you money as most hardware vendors only guarantee parts for a number of years after they have gone end of life.
- Disable unused services. This frees up resources to be used for other systems
- Consider replacing desktops with thin clients (what is a thin client http://en.wikipedia.org/wiki/Thin_client). This centralises the computing resources reducing the amount of time engineers are required on site and with ultra-thin clients can streamline future upgrades.
- Ensure power management settings are applied across all machines so they turn off during periods of inactivity.
- Move storage to 2.5” disks or solid-state disks (SSD), which use significantly less energy.
- Provide a remote access solution to allow employees to work remotely when possible reducing travelling.
- Implement VoIP telephone system, which can allow employees to work from home and have access to telephony services as if they were in the office.
