Environment Preparations


Physical Server

The following table lists necessary servers and their configurations for this tutorial.

Server Hardware Configuration IP Address Hostname Configuration
zstack-mn 4C 8G 172.20.12.249 hostnamectl set-hostname zstack-mn
sharedblock-host1 4C 8G 172.20.11.107 hostnamectl set-hostname sharedblock-host1
sharedblock-host2 4C 8G 172.20.11.244 hostnamectl set-hostname sharedblock-host2
sharedblock-host3 4C 8G 172.20.12.241 hostnamectl set-hostname sharedblock-host3
All servers are installed with ZStack Cloud ISO.
  • All servers are installed with the same version of operating system. For example, all servers are installed with h84r ISO.
  • Install one of the servers as Management Node.
  • Install the other three servers as Compute Node or Expert Mode.
  • When the installation completes, run the following command to configure the hostname resolution:
    [root@sharedblock-host1 ~]# cat /etc/hosts ... 172.20.11.107 sharedblock-host1 172.20.11.244 sharedblock-host2 172.20.12.241 sharedblock-host3 ...
  • Add the three servers to the management node. All hosts will be automatically installed with necessary toolkits including LVM and Multipath.

Now the physical servers are ready.


Storage Network Topology

The following figure shows the network topology of physical servers, storage devices, and a SAN switch.

Figure 1. Network Topology of SharedBlock and iSCSI Storage


For better understanding, the above topology is based on a single-link scenario. If you deploy a SharedBlock storage in a production environment, we highly recommend you use a dual-controller iSCSI storage and enable the high availability mode of the storage network to ensure redundancy.
