New storage is created. The created storage can be accessed from instances by using the network file system (NFS) protocol.
Item | Description |
---|---|
Name | Name of the storage to be created. The NFS access path can be created with the storage name. Storage name is limited to less than 100 alphabetic characters, numbers, and some symbols ('-', '_'). |
Description | A description for storage |
Size | Size of the storage to be created. It can be entered from a minimum of 300 GB to a maximum of 10,000 GB. |
VPC | The virtual private cloud (VPC) to access the storage. |
Subnet | The subnet to access the storage. Only subnets in the selected VPC can be chosen. |
Access Control List (ACL) | A list of the IPs or CIDR blocks that allow read and write permissions. |
Auto Create Snapshot | Snapshots are created automatically at a specified time once per day. When the maximum number of saves is reached, the first automatically created snapshot is deleted. |
Snapshot Storage | If the sum of the snapshot capacity exceeds the set size, the first created snapshot among all snapshots is deleted. |
Encryption | Select whether to enable storage encryption. This must be preceded by setting up encryption key store. |
[Note] The number of subnets available for each project is limited to 3 as of Februrary 2024. To increase the limit, contact the Customer Center.
NAS encrypted storage stores symmetric keys used for encryption in a key store in the NHN Cloud Secure Key Manager service. Therefore, to create encrypted storage, you must create a key store in the Secure Key Manager service in advance. Check the ID of the key store and enter it in the encryption key store settings.
When you create encrypted storage, the symmetric key is stored in the key store you set up. The symmetric key stored in the key store by the NAS service cannot be deleted while using encrypted storage. If you delete encrypted storage, the symmetric key is also deleted.
When you change the key store ID, the symmetric key for encrypted storage you create in the future is stored in the changed key store. Symmetric keys stored in the existing key store are retained.
[Note] You will be charged for key store usage according to the Secure Key Manager service pricing policy. For more information, see Secure Key Manager pricing.
NAS encrypted storage encrypts data with the XTS-AES-256 algorithm using two different symmetric keys. Therefore, two symmetric keys are stored in the key store for each encrypted storage.
NAS storage size is changed. Storage can be scaled up and down even while in use.
The settings for the storage’s access control list is changed.
The settings for Auto Create Snapshot and Snapshot Storage are changed.
NAS storage is deleted.
[Caution] It is recommended to unmount the storage from the associated instance before deleting. Deleting the storage while it is mounted may cause problems on the user's system.
When deleting the storage, all data including snapshots are deleted. Deleted data cannot be recovered.
Snapshots of NAS storage are created immediately.
Storage is restored to the point in time when the snapshot is created. To restore the snapshot, contact the Customer Center.
[Caution] When restoring, snapshots created after the point of restoration are automatically deleted.
A specified snapshot is deleted. Once deleted, snapshots cannot be recovered.
Check various metrics of NAS storage with graphs. After selecting the storage to check, click the Monitoring tab.
The default search period is the latest 1 hour, and you can search any period you want through the search period filter. Descriptions of monitoring metrics are found in the table below.
Metric | Unit | Description |
---|---|---|
Storage capacity | byte | Display the total capacity of storage and the capacity in use. |
Storage usage | % | Display the capacity in use as a percentage of the total storage capacity. |
IOPS | OPS | Display storage operations per second. |
Latency | usec | Display storage latency time. |
Snapshot number | - | Display the number of snapshots in storage. |
Snapshot capacity | byte | Display the amount of capacity that storage is using for the snapshot. |
Inode | - | Display the number of storage inodes. |
Storage status | - | Display storage status. |
Number of client connections | - | Display the number of clients connected to storage. |
Storage can be mounted on instances by using the connection information of the created storage. However, the instance on which storage is mounted must be connected to the specified subnet.
