Deploy SMTX OS (ELF) Cluster

Prerequisites

  • The SMTX OS software has been installed on all the nodes of the SMTX OS cluster.
  • The NICs of both management and storage networks are up, and the NIC of the management network has acquired an IPv4 or IPv6 address.
  • The nginx service and the zbs-deploy-server service have started.
  • The time of all nodes in the SMTX OS cluster needs to be set to the current time.

Before You Deploy​

  1. In the browser, access the cluster configuration page using an IP of the management network on any node in the SMTX OS cluster.

  2. Read the agreement and click to agree.

Step 1: Set Cluster​

In the Cluster settings page, enter a name for the SMTX OS cluster. The system selects the SMTX virtual machine services deployment architecture by default.

Click scan cluster to proceed.

Step 2: Scan Cluster​

Check the scan results after scanning the cluster, making sure that all nodes to be deployed in the cluster are shown in the results.

Step 3: Configure Hosts​

  1. Select the nodes to be deployed in the SMTX OS cluster.

    You can select up to three hosts. Make sure that you have selected the nodes to be deployed in the SMTX OS cluster.

  2. Change the host name corresponding to each node to make it more recognizable.

  3. Click configuration storage.

Step 4: Configure Storage​

  1. Select Tiered or Not tiered.

    • Tiered Storage: Specify the physical disk with a higher speed as the cache disk to take full advantage of hardware performance. For example, if the host in the cluster has both SSD and HDD, select SSD as the cache disk and HDD as the data disk.

    • Non-Tiered Storage: Specify all physical disks as data disks except the one containing the system partition. No disks are set as cache disks. This can only be used in the all-flash mode.

      Note:

      You should select Tiered because SMTX OS Community Edition does not support the all-flash mode.

  2. Specify the physical disk usage.

    • Each host should contain at least one physical disk for metadata partition and one physical disk for storage.
    • You can specify the disk usage by clicking the dropdown box beside the shown physical disk. You will see warning notifications if you are trying to change the system-recommended disk usage. You cannot change the disk usage that has been fixed by the system.

    Once done, click Configure Network.

Step 5: Configure Network​

  1. According to the IP address table in the "Configure SMTX OS Networks" section, fill in the configurations of the management network and storage network in the Configure the cluster network page.

    Note:

    • If no VLANs are planned for the management and storage networks, the VLAN IDs for the management and storage networks can be left blank, with a default value of 0.
    • If no NTP server outside the cluster is available, you can choose a host within the cluster as the NTP server.

  2. Create a VDS for the management network and storage network respectively.

    To create a VDS for the management network:

    • Click Management Network, select Virtual Distributed Switch, then click Create.
    • In the pop-up dialog box, enter a name for the VDS, tick the connected physical port, then click Create.

    You may refer to the steps above to create a VDS for the storage network.

  3. Click Check configuration.

Step 6: Check Configuration​

Check the physical disk usage corresponding to each host you previously set up, and then check the configuration of each VDS for the management and storage networks respectively. Once done, click Perform Deployment.

Step 7: Perform Deployment​

In the Perform Deployment page, you can see the deployment progress of each host, or click View Logs to see details.

When the deployment is complete, you will see the page shown below.
