This article on a new customer-driven capacity upgrade capability with Purity version 6.6.2 originally appeared on the author’s website and has been republished with permission from the author.
Pure Cloud Block Store™ is a data storage platform that leverages cloud native resources to upgrade the raw capacity of the platform. This results in the addition or increase of the capacity of those underlying resources.
With the introduction of the cloud capacity expansion API in Purity version 6.6.2, customers can now increase raw capacity on demand and even automate it. Pure Cloud Block Store customers are no longer required to enlist Pure Storage support to perform this operation. With one command, everything will be handled by the platform. This capability is one of many technological advances Pure Storage is pushing into the cloud.
How It Works
The customer-driven capacity upgrade is currently only possible with the Pure CLI or via a REST API endpoint. It’s supported for Pure Cloud Block Store on both Microsoft Azure and Amazon Web Services (AWS). Although the platforms have quite different underlying architectures, it’s the same command/API endpoint to execute.
To get started, log in to the array using SSH. Once logged in, you can list the current state of the cloud capacity.

purecli@am–662–test–cbs> purearray cloud–capacity list Requested Capacity Current Capacity Status Details 7146825580544 7146825580544 idle |
The next step is to list the available capacity point. The list can vary from one Pure Cloud Block Store model to another.

pureuser@am–662–test–cbs> purearray cloud–capacity list —supported Supported Capacity 3848290697216 7696581394432 15393162788864 |
Finally, you can request the desired capacity by entering the command as shown in the example below:

pureuser@am–662–test–cbs> purearray cloud–capacity setattr —requested–capacity 30786325577728 Requested Capacity Current Capacity Status Details 30786325577728 7696581394432 expanding |
It’s highly recommended to check the resource quota of the underlying infrastructure and health status of the array before starting the capacity upgrade procedure. More about this can be found in the knowledge base documentation listed below:
To learn more about how it works, check out the technical video below, which demonstrates the procedure for increasing the capacity of a Pure Cloud Block Store array running in Azure. Again, the same exact steps can be performed on arrays deployed in AWS.
Summing It Up
Pure Storage continues to innovate and accelerate the customer journey to the cloud by simplifying the overall process. You can take the cloud capacity upgrade as is by manually monitoring and maintaining the lifecycle management of your Pure Cloud Block Store arrays. Or, you can automate the whole process, leveraging cloud event-driven services and the Pure Storage API. In the end, it’s your call.
