Available in VPC
You can add additional storage to a server on top of the default storage.
Note
To enhance service reliability, redundancy between zones is recommended.
- Block Storage redundancy: Block storage is configured on a per-zone basis. Set up redundancy between server and block storage zones to ensure continuity of service without interruption in the event of unexpected storage malfunctions or scheduled change tasks within a specific zone. See Load Balancer overview to set up server redundancy, create block storage in each zone, and connect the respective block storage to the servers in each zone to enhance stability.
- Server redundancy: NAVER Cloud Platform provides a High Availability (HA) structure to prepare for failures in the physical server, such as memory, CPU, and power supply. HA is a policy for preventing hardware failures from expanding to the virtual machine (VM) server. It supports live migration, which automatically migrates the VM on the host server to another secure host server when a failure occurs in the aforementioned host server. However, the VM server is rebooted when an error occurs where Live Migration cannot be initiated. If the service is being operated with a single VM server, it is recommended that you also set up redundancy for VM servers in order to reduce the frequency of failures that may occur as a result of rebooting the VM server.
Caution
Bare metal servers cannot use the add storage feature.
Create storage
To add a storage to the server, you need to first create a storage from the NAVER Cloud Platform console. As the storage capacity, type, and creation method that can be created vary depending on the server's hypervisor type, check before proceeding.
| Type | Maximum additional storage capacity per server | Types of storage that can be created |
|---|---|---|
| KVM-based g3 servers | You can add up to 20 storages with a maximum size of 16 TB each (the number of additional storage excluding the default storage). |
CB1, CB2, FB1, FB2 |
| XEN-based g1, g2 servers | You can add up to 15 storages with a maximum size of 2 TB each (the number of additional storage excluding the default storage). |
SSD, HDD |
Creating KVM-based storage
To create additional storage for g3 servers based on KVM from the NAVER Cloud Platform console:
- In the VPC environment of the NAVER Cloud Platform console, navigate to
> Services > Compute > Server. - Click the Storage menu.
- Click [Create storage].
- On the Create storage popup, enter information and click [Add].
- Hypervisor: Select KVM.
- Storage name: Must be 3-30 characters long. They must contain uppercase and lowercase letters, numbers, hyphens, and/or underscores. Must begin with a letter, and if the name is not entered, it is created automatically.
- Zone: Select the zone to place the storage.
- Storage volume type: Select from the types provided based on the hypervisor types considering the purpose of use. For more information about performance information by volume type, see Check storage information.
- CB1, CB2: For small-sized data accessed frequently
- FB1, FB2: For storing large amounts of data accessed infrequently
- Select snapshot: To create a storage using a snapshot you have, select the desired snapshot (see Create storage with snapshot).
- Size: Entered in units of 10 GB within the scope guided on the interface.
- Max IOPS: Check the maximum IOPS value.
- For CB1 and CB2 as the selected storage type, the value varies with the specified storage size.
- For FB1 and FB2 as the selected storage type, 500 IOPS.
- Storage return protection: Select whether to protect storage from being returned.
- Memo: Enter necessary descriptions related to storage creation within 1,000 bytes.
- In the confirmation popup, review the details and click [OK].
- The created storage is displayed on the storage list.
- Once you create a storage and complete the tasks including connecting to a server, disk partitioning, formatting, and mounting, you are ready to use the storage.
- To connect storage to a server, proceed with the Server connection task.
- To use storage while it's connected to a server, proceed with the Mount storage (Linux) or Register storage volume (Windows) tasks.
Create XEN-based storage
To create additional storage for g1 and g2 servers based on XEN from the NAVER Cloud Platform console:
- In the VPC environment of the NAVER Cloud Platform console, navigate to > Services > Compute > Server.
- Click the Storage menu.
- Click [Create storage].
- On the Create storage popup, enter information and click [Add].
- Hypervisor: Select XEN.
- Storage name: Must be 3-30 characters long. They must contain uppercase and lowercase letters, numbers, hyphens, and/or underscores. Must begin with a letter, and if the name is not entered, it is created automatically.
- Zone: Select the zone to place the storage.
- Storage volume type: Select from the types provided based on the hypervisor types considering the purpose of use.
- SSD: For high-performance I/O
- HDD: For general services
- Select applied server: When connecting storage to a server right after creating it, select the server to connect to. For more information about the applied server, see Connect to server.
- Select snapshot: To create a storage using a snapshot you have, select the desired snapshot (see Create storage with snapshot).
- Size: Entered in units of 10 GB within the scope guided on the interface.
- Max IOPS: Check the maximum IOPS value.
- For SSD as the selected storage volume type, the value varies with the specified storage size.
- For HDD as the selected storage volume type, the IOPS value is fixed.
- Storage return protection: Select whether to protect storage from being returned.
- In the confirmation popup, review the details and click [OK].
- The created storage is displayed on the storage list.
- Once you create a storage and complete the tasks including connecting to a server, disk partitioning, formatting, and mounting, you are ready to use the storage.
- To connect storage to a server, proceed with the Server connection task.
- To use storage while it's connected to a server, proceed with the Mount storage (Linux) or Register storage volume (Windows) tasks.
Note
The Storage creation menu that appears when clicking the [Manage servers and change settings] on the Server interface is also possible for XEN-based storage. For more information, see Manage server.
