Cloud Parallel File Storage (CPFS) supports high throughput and high IOPS, which is suitable for high-performance computing business. You can enable shared access to a file system multiple compute nodes of Machine Learning Platform for AI (PAI) to over the Portable Operating System Interface (POSIX) protocol. This topic describes how to create a CPFS for Lingjun file system.
Prerequisites
CPFS is activated.
If you log on to the Apsara File Storage NAS (NAS) console for the first time, activate CPFS as prompted.
Your account is added to the whitelist of CPFS for Lingjun.
CPFS is in invitational preview. To use CPFS for Lingjun, submit a ticket to add your account to the whitelist of CPFS for Lingjun.
Usage notes
A CPFS for Lingjun file system can be used only with PAI-Lingjun AI Computing Service and cannot be accessed by Elastic Compute Service (ECS) instances.
Create a CPFS for Lingjun file system
Log on to the NAS console.
On the Overview tab of the Overview page, click Create below CPFS for Lingjun in the File System Selection Guide.
On the CPFS (Pay-As-You-Go) page, configure the parameters, such as Cluster ID, Configure Capacity, and Resource Group.
Parameter
Description
Cluster ID
The ID of the Lingjun cluster for which you want to create a CPFS for Lingjun file system based on your business requirements.
Configure Capacity
The capacity of the CPFS for Lingjun file system.
You must evaluate and specify the maximum capacity of the file system based on your business requirements to ensure that the file system has sufficient capacity. If the capacity usage exceeds the configured capacity, the file system returns a "no space" error.
Resource Group
Optional. The resource group to which the file system belongs. You can use resource groups to manage NAS resources within your Alibaba Cloud account by category and group. You can manage permissions, deploy resources, and monitor resources based on groups without the need to separately process each resource. For more information, see Best practices for designing resource groups.
If you do not select a resource group, the file system is automatically classified into the default resource group after the file system is created.
To create a resource group, click Create Resource Group. In the Create Resource Group dialog box, configure the Resource Group ID and Resource Group Name parameters, and then click OK.
Click Buy Now and complete the payment as prompted.
After you complete the payment, you can view the file system that is being created on the page.
