Cloud Parallel File Storage (CPFS) delivers high throughput and high IOPS (input/output operations per second) for HPC (high-performance computing) workloads. Multiple compute nodes — ECS (Elastic Compute Service) instances, containers, and Cloud Desktops — can share a single file system over POSIX or NFS.
Prerequisites
Before you begin, ensure that you have:
-
CPFS activated
If this is your first time logging in to the CPFS console, activate the CPFS service as prompted.
A VPC (virtual private cloud) and a vSwitch created in the target region. For more information, see Create a VPC and a vSwitch.
Create a 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. This feature is currently available only to whitelisted users.
Log in to the CPFS console.
In the CPFS section of the Overview page, click Create.
-
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 instance must be in the same region. File systems and ECS instances in different regions cannot communicate with each other.
Zone
Select a zone within the region.
A zone is a physical area with independent power and network resources. Select the same zone as your ECS instance to minimize access latency.
Type
Select 100 MB/s/TiB Baseline for standard HPC workloads with moderate bandwidth requirements. Select 200 MB/s/TiB Baseline for latency-sensitive or bandwidth-intensive workloads — for the same capacity, this type delivers twice the throughput. For detailed specifications, see Specifications.
Capacity of CPFS File System
Set the capacity based on your expected peak usage.
Size for your maximum workload to avoid running out of space. CPFS does not automatically expand capacity when provisioned storage is exhausted.
Resource Group
Optional. Select a resource group for management purposes. If left blank, the file system is assigned 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, set Resource Group Identifier and Resource Group Name, and then click OK.
VPC
Select the same VPC as your ECS instance. The file system is only accessible from within the selected VPC.
vSwitch
Select a vSwitch in the VPC.
For optimal performance, select the same vSwitch as your ECS instance.
Service-linked Role
Authorize CPFS to configure network connectivity between the CPFS cluster and your VPC. This role is required to create the file system.

Click Buy Now and complete the purchase.
After the purchase is confirmed, go to to find the new instance. Creation takes 15 to 20 minutes.
What's next
After the file system is created, mount it on your compute nodes — ECS instances, ACK clusters, or Cloud Desktops — to start accessing data. Review the client requirements and mounting scenarios in Mount and access to choose the right approach for your workload.
