CPFS (Cloud Parallel File Storage) provides high throughput and high IOPS (input/output operations per second) and is designed for high-performance computing (HPC) workloads. Multiple compute nodes, such as ECS instances, containers, and Cloud Desktops, can share the same file system over the POSIX or NFS protocol.
Prerequisites
-
Activate the CPFS service.
If you are using the CPFS console for the first time, activate the service as prompted.
-
Create a VPC and a vSwitch in the target region. For more information, see Create a VPC and a vSwitch.
Create a general-purpose CPFS file system
To create a CPFS file system with zone-redundant storage, see Storage redundancy. CPFS with zone-redundant storage provides a 99.99% SLA (Service Level Agreement) and cross-zone disaster recovery capabilities. This feature is currently available only to whitelisted users.
-
Log on to the CPFS console.
-
On the Overview page, at the bottom, click Create CPFS File System.
-
On the CPFS (Pay-As-You-Go) page, configure the following parameters.
Parameter
Description
Region
Select the region where you want to create the file system.
The file system and the ECS instances must be in the same region.
Zone
Select a zone within the region.
A zone is a physical location with independent power and networking. To reduce cross-zone latency, select the same zone as your ECS instances.
Type
Select 100 MB/s/TiB Baseline for HPC workloads with moderate bandwidth requirements, or select 200 MB/s/TiB Baseline for latency-sensitive or bandwidth-intensive workloads. For the same capacity, the 200 MB/s/TiB baseline provides twice the bandwidth. For more information about specifications, see Specifications.
CPFS Provisioned Capacity
Set the capacity based on your expected peak usage.
CPFS does not automatically expand capacity when the provisioned capacity is exhausted. Exceeding the provisioned capacity results in a 'no space' error.
Resource Group
(Optional)
Select a resource group to group and manage your resources. If you do not select a resource group, the file system is added to the default resource group. For more information, see Best practices for designing resource groups.
To create a new resource group, click Create Resource Group. In the Create Resource Group dialog box, configure Resource Group Identifier and Resource Group Name, and then click OK.
VPC
Select the same VPC as your ECS instances. The file system is accessible only from within the selected VPC.
vSwitch
Select a vSwitch in the VPC.
For optimal file system performance, select the same vSwitch as your ECS instances.
Service-linked Role
This role authorizes CPFS to configure network connectivity between the CPFS cluster and your VPC. This authorization is required to create a file system.
-
Click Buy Now and follow the on-screen instructions to complete the purchase.
After the purchase is complete, go to the to view the new file system. The creation process takes 15 to 20 minutes.
Next steps
After you create the file system, mount it on compute nodes (such as ECS instances, ACK clusters, or Cloud Desktops). Before you mount the file system, refer to the client requirements and mounting scenarios in Mount and access to choose the mounting method that best fits your workload.
