Create a Burst Quota

You can define a burst quota that allows certain users and groups to exceed a resource limit.

Consider an MSP that sells web development LAMP stacks to Independent Software Vendors (ISVs). To allow access to ISVs that need more resources the MSP created the Advanced Development Package. This package is based on the Basic Development Package, with the addition of a 50% burst quota. It includes the following items:

• 4 CPUs with the ability to burst to a maximum of 6 CPUs
• 4 GB RAM with the ability to burst to a maximum of 6 GB
• 10 Mbps network bandwidth with the ability to burst to a maximum of 15 M
• 500 GB disk space with the ability to burst to a maximum of 750 GB

When users reach any burst limit (CPU, memory, bandwidth, or disk space), no additional resources of that type are provisioned, and the operation fails. For example, when an operation attempts to provision more than 6 GB of RAM, the operation fails.

Follow these steps:

1. Open the grid shell from the GUI.
2. Create a burst quota entry as follows:

   group create ISVAdvancedDevGroup
   quota put ISVAdvancedDevGroup cpu=4 mem=4G bw=10M disk=500G burst=50 description="Burst Quota"
