Huawei data storage

Deckhouse provides support for Huawei Dorado storage systems, enabling volume management in Kubernetes using a CSI driver through the creation of custom resources like HuaweiStorageClass. This solution ensures high-performance and fault-tolerant storage, making it an optimal choice for mission-critical workloads.

This page provides instructions on connecting Huawei Dorado to Deckhouse, configuring the connection, creating StorageClass, and verifying storage functionality.

System requirements

• Presence of a deployed and configured Huawei storage system.
• Unique IQNs in /etc/iscsi/initiatorname.iscsi on each Kubernetes node.

Configuration

Note that all commands must be run on a machine that has administrator access to the Kubernetes API.

Enabling the module

To support Huawei Dorado storage systems, enable the csi-huawei module. This will ensure that all cluster nodes have:

• Registration of the CSI driver.
• Launch of service pods for the csi-huawei components.

d8 k apply -f - <<EOF
apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: csi-huawei
spec:
  enabled: true
  version: 1
EOF

Wait until the module transitions to the Ready state. Check the module’s status with the following command:

d8 k get module csi-huawei -w

Creating a StorageClass

To create a StorageClass, you need to use the HuaweiStorageClass and HuaweiStorageConnection resource. Here is an example command to create such a resource:

• Creating a HuaweiStorageConnection resource:

  d8 k apply -f -<<EOF
  apiVersion: storage.deckhouse.io/v1alpha1
  kind: HuaweiStorageConnection
  metadata:
    name: huaweistorageconn
  spec:
    storageType: OceanStorSAN
    pools:
      - test
    urls: 
      - https://192.168.128.101:8088 
    login: "admin"
    password: "ivkerg43grdsf_"
    protocol: ISCSI
    portals:
      - 10.240.0.101
      - 10.250.0.101 
    maxClientThreads: 30
    
  EOF
  

  Verify the creation of the object using the following command (Phase should be Created):

  d8 k get huaweistorageconnections.storage.deckhouse.io <huaweistorageconnection name>
  

• Creating a HuaweiStorageClass resource:

  d8 k apply -f -<<EOF
  apiVersion: storage.deckhouse.io/v1alpha1
  kind: HuaweiStorageClass
  metadata:
    name: huaweisc
  spec:
    fsType: ext4
    pool: test
    reclaimPolicy: Delete
    storageConnectionName: huaweistorageconn
    volumeBindingMode: WaitForFirstConsumer
  EOF
  

  Verify the creation of the object using the following command (Phase should be Created):

  d8 k get huaweistorageclasses.storage.deckhouse.io <huaweistorageclass name>
  

Module health verification

To verify module health, ensure that all pods in the d8-csi-huawei namespace are in the Running or Completed state and are running on every node in the cluster:

d8 k -n d8-csi-huawei get pod -owide -w
