：Add or remove a storage pool

Add a storage pool

1. Log on to the DBS console. In the left-side navigation pane, click Storage Pool. On the Storage Pool page, click Add Storage Pool.

2. Set the parameters to specify a storage pool.

   You can set the Storage Type parameter to NAS or OSS For User.

   • If you set the Storage Type parameter to NAS, set the parameters that are described in the following table to add a self-managed NAS file system as a storage pool.

     Parameter	Description
     Storage Type	The type of the storage pool. In this example, specify NAS as the value of this parameter.
     Protocol Type	The protocol that is used by the storage pool. Valid values: NFS: the Network File System (NFS) protocol.
     Connection Method	The method that is used to connect to the storage pool. Valid values: VPC: Before you specify a virtual private cloud (VPC), make sure that the self-managed NAS file system is connected to the VPC. We recommend that you set the Connection Method parameter to VPC. For more information, see Connect a data center to a VPC. A VPC is a private network that is dedicated to your Alibaba Cloud account. You can connect to a storage pool over a VPC to ensure higher security and lower network latency. Public Network: The self-managed NAS file system is connected to DBS over the Internet. Note You are not charged for traffic that is generated when you access the self-managed NAS file system over the Internet. However, the connection may be exposed to security risks. We recommend that you use a VPC to ensure higher security.
     Storage pool name	The name of the storage pool.
     Protocol Version	The version of the NAS file system. If you set the Protocol Type parameter to NFS, only NFS V4 is supported. For more information, see Comparison of Network File System version 4 to Prior Versions.
     Region	If you set the Connection Method parameter to VPC, select the region in which the VPC is deployed. If you set the Connection Method parameter to Public Network, select the region in which your NAS file system is deployed or a region that is close to the region in which your NAS file system is deployed.
     Peer VPC	The VPC to which the self-managed NAS file system is connected. Note This parameter is displayed only if you set the Connection Method parameter to VPC.
     Address	The private or public endpoint of the self-managed NAS file system. If you set the Connection Method parameter to VPC, you must specify the IP address of the self-managed NAS file system. If you set the Connection Method parameter to Public Network, you can specify the IP address or domain name of the self-managed NAS file system.
     Port Number	The port that is used to connect to the self-managed NAS file system.
     NAS Server Path	Optional. The mount target of the self-managed NAS file system.
     Storage Capacity	The storage capacity of the self-managed NAS file system. Unit: GB. Default value: 1024. Minimum value: 10.

   • If you set the Storage Type parameter to OSS For User, set the parameters that are described in the following table to add an OSS bucket as a storage pool.

     Parameter	Description
     Storage Type	The type of the storage pool. In this example, specify OSS For User as the value of this parameter. This indicates that an OSS bucket is used as a storage pool. For more information, see What is OSS?.

     Storage pool name	The name of the storage pool.
     Region	The region in which the OSS bucket is deployed.
     Bucket Name	The name of the OSS bucket. To view information about existing OSS buckets within your Alibaba Cloud account, go to the Buckets page in the OSS console. If no available buckets exist, create a bucket. For more information, see Create buckets.
     AccessKey ID	The AccessKey ID that is used to access the OSS bucket. For information about how to obtain an AccessKey ID, see Obtain an AccessKey pair.
     AccessKey Secret	The AccessKey secret that is used to access the OSS bucket. For information about how to obtain an AccessKey secret, see Obtain an AccessKey pair.
