To perform automated installation of the VSA cluster, you can use the automated installer script and enter the required parameters.

Verify that your environment meets the requirements to perform automated installation as described in VSA Automated Installer Requirements.

On the Windows Server system, run the installation command from the automated installer package.

The following example shows how to install a VSA cluster with two ESXi hosts, with two specified VLAN IDs, and the specified VSA cluster IP address as the starting IP address from a range of free and incremented IP addresses.

install.exe -fv Front_End_VLAN_ID -bv Back_End_VLAN_ID -si VSA_Management_address -u ESXi_root_user -p ESXi_root_password -ei ESXi_Host_1_IP ESXi_Host_2_IP ESXi_Host_3_IP

The VSA automated installer scans the subnet for ESXi hosts for available IP addresses and performs silent installation of the VSA cluster components.

vCenter Server 5.0 (if not already installed on the Windows system)

vSphere Client 5.0 (if not already installed on the Windows system)

VSA Manager

VSA cluster service (installed, but used only if 2 ESXi hosts are available in the subnet)

After all components are installed, the installer performs the tasks to install a VSA cluster.


Creates a datacenter and adds the ESXi hosts to it.


Updates the network configuration of the ESXi hosts.


Deploys the vSphere Storage Appliance onto the ESXi hosts.


Starts the VSA cluster service if only 2 ESXi hosts were present.


Powers on each instance of vSphere Storage Appliance and creates the VSA cluster.


Mounts the VSA datastores to each ESXi host in the datacenter.


Do not rerun the VSA automated installer after a VSA cluster has been created.
