Change site collection storage and server resource quotas

The storage quota of a SharePoint Online site collection is the maximum amount of storage space (in MB) allowed for that site collection. The resource usage quota is a site collection value that is generated by SharePoint Online. Resource quotas can reduce the risk that custom code may cause poor performance in the site collection.

Overview

As a SharePoint Online administrator for SharePoint Online for Enterprises, you can specify how much storage is allocated for each site collections. You can change the storage quota if the site collection needs more or fewer megabytes (MB). The minimum amount per site collection is 100 MB. You can also set an alert to be notified by email when the storage for the site collection approaches its limit.

As an administrator, you can also specify the resource usage quota. SharePoint then monitors the resource usage level for a site collection against this quota. To monitor the resource usage level, SharePoint collects performance data such as processor time and unhandled exceptions that relate to custom code being used in sandboxed solutions. When resource usage level exceeds the daily quota, SharePoint turns off the sandbox for the site collection; then, custom code cannot run. Resource usage quotas can reduce the risk that custom code will adversely affect the performance of a site collection. You can also set an alert to be notified by email when the resource usage level for the site collection approaches its limit.

Change the server resource quota for a site collection

As a SharePoint Online service administrator, you can specify a server resource quota. You can also specify the warning level at which you are sent an email alert that the site collection approaches its resource limit. The purpose of this quota is to set a maximum percentage of server resources (such as CPU and RAM) that your site collection should use. The quota helps prevent one site collection from depleting server resources, which might adversely affect performance for all site collections.

  1. Sign into Office365.
  2. Click the Admin tab at the top of the Office 365 Administration Center.
  3. Select the check boxes next to the site collections whose server resource quotas you want to change.
  4. On the Site Collections tab, in the Manage section, click Server Resource Quota.

In the set server resource quota dialog box, enter a maximum number of resources. The default number of available resources for a site collection is 300. (Notice that this dialog lists the total number of resources that are available to you.)

  1. To configure an email alert that notifies you when the resource usage level is nearing its quota, select the Send e-mail when… check box. Then, enter a number from 1 to 100 for the percentage of resource quota you want to reach before an email alert is triggered.
  2. Click Save.
