Before configuring PowerScale CloudPools on the PowerScale cluster, the Alibaba Cloud needs to be configured properly. The following are the general considerations and best practices when configuring Alibaba Cloud for CloudPools.
- URI for CloudPools: The URI is region-specific. For example, the URI for region oss-us-west-1 is https://oss-us-west-1.aliyuncs.com. The mapping region need to be set when configuring the CloudPools on a PowerScale cluster. For details about Regions and endpoints, see Regions and endpoints on the Alibaba Cloud website. CloudPools supports the standard Object Storage Service (OSS).
- Resource access management (RAM): A RAM user need to be created with proper permissions before setting up CloudPools on a PowerScale cluster. CloudPools uses the RAM user to manage buckets and objects for CloudPools operations. The policy AliyunOSSFullAccess needs to be attached to the RAM user. For more details, see Permission granting in RAM on the Alibaba Cloud website.
