Specifically, use ECS or BMS for server computing resources, and EVS and SFS for storage.
What Should I Do If a Linux EVS Disk Is Attached to a Windows Server? Can I Attach an EVS Disk Purchased with a Yearly/Monthly Server to Another Yearly/Monthly Server? Can I Change the Function of a System Disk or Data Disk Purchased Along with a Server?
Resilience RDS uses EVS disks to store data, providing three-copy storage and 99.9999999% data durability. It also provides features like cross-region replication, multi-AZ data redundancy, and intra-AZ anti-affinity, to guarantee reliability and availability of your instances.
You can create a data disk image from an ECS and then use the image to create new EVS disks. This is a convenient way to migrate data from an ECS to EVS disks. You are advised to use data disk images in the following scenarios: Migrate service data on an ECS to another account.
Querying the Price of a Product Service Object Partner's customers Scenario Description Customers can view introductions to cloud services, such as ECS, EVS, VPC, and EIP, and purchase the cloud services.
EVS After you click upload, the data is uploaded to the instance container, that is, the ~/work directory on the Terminal page. Parent topic: ModelArts Standard Notebook
Advantages Extensive Service Integration By integrating with OBS, EVS, and IMS, you can use KMS to manage the keys of the services or use KMS APIs to encrypt and decrypt local data.
API Overview A FlexusL instance is a package of resources that include cloud servers, EIPs, EVS disks, CBR vaults, and HSS. Cloud servers are servers in a FlexusL instance. This section describes some common APIs of FlexusL instances.
Scenarios When the EVS disk space on a server is insufficient, the server running speed will be affected, which will further affect user experience.
The differences between cloud SSDs and local SSDs are as follows: Cloud SSDs Cloud SSDs use EVS as storage media and can be scaled out as data grows. This is more flexible. Cloud SSDs are not bound to the ECS flavor.
Method Operation Instruction Restoring data by recovering the disk If you have enabled EVS recycle bin, check whether the deleted disk is in the recycle bin. NOTE: EVS disks released after the retention period expires will not be moved to the recycle bin.
Troubleshooting Methods When attaching an EVS disk, use parameters without UUID control or reallocate a new UUID to ensure that each UUID is unique. Solution Log in to the server to which EVS disks failed to be attached.
Related Services Elastic Cloud Server (ECS) An ECS is a basic computing unit that consists of vCPUs, memory, OS, and EVS disks. RabbitMQ instances run on ECSs. A broker corresponds to an ECS. Elastic Volume Service (EVS) EVS provides block storage services for ECSs.
