Precautions

1. For large cluster projects, it is recommended to use multiple volumes. It is recommended that the number of nodes per volume be less than 12 and not more than 16 as far as possible. For example, 48 nodes in the cluster are recommended to be divided into four volumes and 12 nodes per volume.

2. Using RAID volumes to build virtual storage is not recommended because they generally do not support hot plugs. RAID should be configured as JBOD passthrough. If JBOD is not supported, disable RAID and use non-RAID.

Steps

1. Navigate to Storage > Virtual Storage, click New, and select the volume type as Ordinary datastore.

2. Select the corresponding method and nodes to create a virtual datastore. Since we are creating the first virtual datastore, choose the Use disks on new hosts. You can enable RDMA for nodes as needed. For the introduction of the RDMA feature and the precautions for enabling RDMA, refer to Section 3.5.2 Enable RDMA (Optional).

3. Select the hard disk to be added to the node. Configure hard disks and hard disk groups, and then make a detailed usage plan for each node's disk. The system will automatically detect the disks of all nodes in the cluster. By default, mechanical disks are selected as data disks and solid-state disks as cache disks. Using the default configuration is recommended. If you need to deploy multiple databases, you need to plan to reserve the disks of the second database group.

Select the disks that will be used to create a virtual datastore.

For a hybrid datastore, at least one SSD is required as a cache disk.

4. Confirm the details and proceed.

5. The following page displays virtual storage configurations, including available disk space, number of data copies, and the total number of disks. After confirming configurations, click OK. Then, input the administrator account password: admin. Then, click Finish to begin initializing virtual storage.
