Process Overview

Figure 1 shows the process for using EVS.

Figure 1 Process overview

EVS disks can be attached to servers to be used as system disks or data disks. For details, see Table 1.

Table 1 Method of creation

Function	Description	Method
System disk	System disks are created together with servers. You cannot create them separately.	See section "Creating an ECS" in the Elastic Cloud Server User Guide. See section "Creating a BMS" in the Bare Metal Server User Guide.
Data disk	You can create data disks together with servers or separately.	See section "Creating an ECS" in the Elastic Cloud Server User Guide. See section "Creating a BMS" in the Bare Metal Server User Guide. Creating an EVS Disk

Figure 2 shows how to purchase a data disk separately.

Figure 2 Process overview

1. Make preparations: Register an account on the console and obtain permissions required for creating ECSs and EVS disks.

2. Create an EVS disk: Configure the disk parameters, including the disk type, capacity, name, and other information by referring to Creating an EVS Disk.

3. Attach the data disk. Attach the separately created disk to an ECS. For details, see the following sections:

   • Attaching a Non-Shared Disk

   • Attaching a Shared Disk

4. Initialize the data disk: After the data disk is attached, log in to the ECS and initialize the disk before using it. For details about the initialization scenarios and how to initialize the disk, see the following sections:
