You can customize the VM instance resources to your needs from VM Instances module in itopia. To see VM instance details and current resource allocation, just click on the VM instance name. 

Details will be displayed as below: 

To edit the resources, mark the checkbox next to the VM instance name and click the pencil icon to enter the edit mode:

Note: before editing RAM and CPU manually on session host VM instances, make sure you disable autoscaling. 

Increase Storage

Make sure your VM instances are powered on to expand disk size. Reboot is not needed for the changes to apply.
In the Edit window, click the pencil icon next to the existing disk to change the storage size:

Note: Adding more storage makes it available to the disk but doesn't add it to the volume. Make sure that after changing the disk size you extend the volume in the VM instance (in Disk management)

Google currently doesn't allow you to remove additional storage once allocated, even if you haven't expanded the disk, so always be sure you're adding the correct amount of space to the right disk. 

To add a new disk, define the Disk size and Disk Type first and then click on the + sign on the right to add the disk to the VM instance.

After increasing the storage or adding a disk a task is created in itopia Tasks module to remind you to apply the changes in the VM instance. After you mark the task as complete, the VM instance status will change from Pending to Ready.

Important: When allocating drive space, keep in mind that due to Windows limitations, you cannot expand the boot disk to more than 2 TB.

Change RAM and CPU

You can edit your resources (RAM and CPU) on your session host instances through the Autoscaling section in Collection pools module. You can select when the resources will scale up depending on number of users you define. If the default resource configuration doesn't work for you, you can disable the autoscaling completely and set up the resources manually as described below.

After disabling the autoscaling you can adjust RAM and CPU selecting a different machine type. If none of them is convenient for you, select Custom option to specify the exact amounts of RAM and CPU:

After you’re done, you can force the update to propagate in the VM instances enabling the option Force update. Users will receive a message that they will be disconnected in 5 min and the changes will be applied.

If you don’t force the update, changes will be applied at 12 AM.

Managing Firewall Ports

In Allow Firewall Port section you can specify ports to be open for the VM instance. Port should be added only in case external access to the server is needed. You can add as many ports as needed clicking on the + sign. 


IMPORTANT: If you make changes to an VM instance directly in Google, you can affect the correct functionality of some features in itopia.
