Change CPU, memory and disk

Your plan reserves a number of cores, an amount of memory and an amount of disk. The Plan tab shows what it includes, and lets you give the server less or more of it, up to what you already pay for.

This costs nothing. You are moving within the allowance you already have.

The sliders#

Open your server and click Plan. The second card, Resources, holds three sliders. Each row shows what your plan allows, what the server has now, and what it will have.

Cores. From 1 up to what your plan includes. Both directions.

Memory. From 1 GB up to what your plan includes. Both directions. The step is 512 MB on smaller plans and 1 GB once the plan includes 8 GB or more.

Disk. From the current size up to what your plan includes. Up only. Shrinking a disk would destroy the file system, so the slider starts at the size the server already has.

Move the sliders, then click Apply allocation. Reset puts them back to where they were.

What happens next#

Disk growth is applied straight away. The volume gets bigger immediately, and the file system inside the server expands on the next boot.

Cores and memory are different. They are written down for the server but the running machine keeps its old allocation until it has been powered off and on again. A clean reboot from inside the server is not enough. It has to be a full power cycle.

The panel handles that for you. Go back to Overview and you will see a note saying new limits are staged, with a button: Apply now with a restart. Click it when you are ready for the server to go down for a moment. The server stops, picks up the new allocation and starts again.

If you would rather not take the downtime now, leave it. The change waits and applies the next time the server is powered off and on for any reason.

Why you would use less#

Memory is the common one. If you run one small service on a plan with 8 GB, dropping the server to 2 GB does not save you money, but it does make the server behave more like the smaller machine you will eventually move it to. Mostly people leave the sliders at maximum and that is the right answer.

When the sliders are at the top#

The card shows At plan maximum and the footer points you at the plans. Moving to a bigger plan is not something the panel does. Email [email protected] and we will arrange it. A plan change takes effect at the end of your current term.

If all you need is a bit more of one thing, the add-ons page is usually quicker. Memory, cores and disk can all be added there.

What else is on the Plan tab#

The first card names your plan and lists what it includes: cores, memory, disk and the monthly bandwidth allowance with the uplink speed. Those are the figures your plan is billed on.

If it refuses#

• A suspended or terminated service cannot be resized. Settle the invoice first.
• Storage cannot be shrunk. The slider will not let you, and the server refuses it too.
• Something else is running on the server. Only one operation happens at a time. Wait for the banner at the top to clear.
