Description

The private storage network is to build a communication network for virtual storage alone, which can improve the efficiency of data transmission and ensure the consistency of data synchronization.

Usually, virtual storage contains very important user data. To avoid the risk of data synchronization caused by network problems, a storage private network can be built to protect it. However, the storage private network requires the physical node to provide a separate interface for storage communication.

Precautions

1. Check that the storage private interface adopts the link aggregation mode or 10 Gigabit interface.
2. It is forbidden to adjust the network wiring during the operation of the HCI platform because plugging and unplugging the network cable will cause the alternate network disconnection, resulting in data split-brain and data loss.
3. Do not remove the cache disk during HCI operation. Replace disks through Disk Management if necessary, or stop processing.
4. When the storage is changed from None link aggregation to another mode, it is necessary to ensure that the node has at least one free network interface. Otherwise, the network deployment mode will remain the same.

Prerequisites

All running virtual machines and virtual network devices need to be shut down.

Steps

1. Go to Nodes > Communication Interface and select Storage Network Interface.

2. On the Storage Network Interface select Reset Storage Area Network.
3. Based on the diagram, select the Dedicated Mode.

4. Specify the deployment mode of the storage network interface. In this case, select Link aggregation disabled.

5. Configure the storage network interfaces.

6. Configure the private network IP address for the storage network. It is compulsory that the private network IP address of the storage must be in the same IP segment.

7. Verify the storage network interface configurations.
