Cloud Parallel File Storage (CPFS) for Lingjun is an ultra-high performance file storage service provided by Alibaba Cloud CPFS. CPFS for Lingjun supports end-to-end Remote Direct Memory Access (RDMA) networks and can be used in intelligent computing scenarios such as AIGC and autonomous driving. This topic describes how to create a CPFS for Lingjun file system and the subsequent operations.
Prerequisites
CPFS is activated.
If you log on to the 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 for Lingjun 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 Lingjun resources, general computing resources, and single-tenant Lingjun resources. It cannot be accessed by Elastic Compute Service (ECS) instances.
Procedure
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 section.
On the CPFS for Lingjun (pay-as-you-go) page, configure the parameters, such as Cluster ID, Capacity, and Resource Group.
Parameter
Description
Zone
The zone in which the Lingjun cluster resides.
Cluster ID
The ID of the Lingjun cluster for which you want to create a CPFS for Lingjun file system.
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 CPFS for Lingjun 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 Identifier and Resource Group Name parameters, and then click OK.
Click Buy Now and complete the payment as prompted.
After you complete the payment, go back to the NAS console and choose in the left-side navigation pane. On the page that appears, you can view the file system that is being created.
What to do next
After the CPFS for Lingjun file system is created, you must mount the file system in Platform for AI (PAI) computing resources. The method used to mount a CPFS for Lingjun file system varies with the type of PAI computing resources. Mount the file system based on the type of your PAI computing resources.
Lingjun resources
Create a dataset based on the CPFS for Lingjun file system and select the dataset when you create an AI development task in the PAI console. For more information about how to create a dataset, see Create and manage datasets.
General computing resources
Create a Virtual Private Cloud (VPC) mount target for the CPFS for Lingjun file system. Then, create a dataset based on the file system and select the dataset when you create an AI development task in the PAI console. For more information about how to create a dataset, see Create and manage datasets.
Single-tenant Lingjun resources
Configure the information about the CPFS for Lingjun file system when you create a Lingjun cluster. The CPFS cluster is initialized during the automatic deployment of the Lingjun cluster. For more information, see Activate and configure other Alibaba Cloud services.
