Follow these essential post-installation steps to get VAST Cluster configured and ready to use.
The following pre-requisites are assumed:
All VAST Cluster hardware components are fully installed in a rack, by VAST Data field personnel.
VAST Data field personnel have completed the installation by defining the cluster through the VAST Web UI. The cluster is a manageable entity comprising all installed components.
Make sure your PC has network access to all of the VAST Cluster compute servers (CNodes).
<VMS_VIP>is the management VIP that you provided during installation. This is the IP used to connect to the VAST Cluster management server (VMS).
The VAST Web UI opens.
If this is your first time connecting to the VAST Web UI, click I agree to accept the VAST Data End User License Agreement.
Enter your Username and Password to log in.
For first time login, use the factory default management user account credentials:
VAST Cluster has one factory default management user account. You cannot delete the factory default management user account or reduce its permissions. After first time login, you can change the password and create additional management accounts.
You're now logged into the VAST Web UI and you're viewing the Dashboard.
For good security practice, we recommend you change your management password immediately.
From the menu (click at the top left of the page), select Security and then select the Managers tab.
Identify the manager named admin and click anywhere in the manager's row.
In the Password field, enter a new password.
In the Retype Password field, enter the password again.
Your new password is saved.
VIP pools are ranges of IP addresses that VAST Cluster can use for listening for data traffic.
VAST Data recommends a minimum of two VIPs per CNode. For optimal load balancing, we encourage four VIPs per CNode for clusters with one Cbox (four CNodes); and four or more VIPs per CNode for larger clusters.
To learn more about VIP pools, see Managing Virtual IP (VIP) Pools.
Configure one or more VIP pools to provide a recommended number of VIPs.
From the menu (click ) select Configuration and then select the Virtual IP Pools tab.
Click and complete the fields:
Start IP (required)
Enter the IP at the start of the range.
End IP (required)
Enter the IP at the end of the range.
Subnet CIDR (required)
Specify the subnet in Classless Inter-Domain Routing (CIDR) notation.
In CIDR notation, the subnet is expressed as the number of bits of each IP address that represent the subnet address. For example, the subnet mask 255.255.255.0 is expressed as 24 in CIDR notation.
If your storage clients are on multiple subnets and you are routing your client storage traffic through a local gateway device, enter the gateway IP.
Select the cluster you are configuring the IP pool for.
VLAN (from VAST Cluster 2.2.0)
If you want to tag the VIP pool with a specific VLAN on the data network, enter the VLAN number (0-4096). See also Tagging VIP Pools with VLANs.
If you want to dedicate a specific group of CNodes to the VIP pool, open the drop-down and select all the CNodes you want to include in the group. The VIPs in this pool will only be distributed among the selected CNodes.
If you do not specify any CNodes, the pool will be distributed among all active CNodes.
The virtual IP pool is saved. IP addresses from the pool are assigned automatically to the CNodes. You can view the assigned virtual IPs per CNode on the Virtual IPs tab.
VAST Cluster compute load is designed to be distributed across all the compute servers (CNodes) in the cluster. This is achieved by configuring a 'round robin' load balancing configuration on your DNS server.
Perform the following configurations on your DNS server:
Set up a Fully Qualified Domain Name (FQDN) for VAST Cluster.
Map all the IPs in your virtual IP pool(s) to the VAST Cluster FQDN in a 'round robin' load balancing configuration.
The call home feature sends non sensitive data from your VAST Cluster to our central support server to enable us to provide proactive analysis and fast response on critical issues.
From the menu (click ) , select Settings and then select the Call home tab.
Complete the General Setup fields:
Your customer name.
The name of the site where the cluster is installed.
The location of the site.
The frequency with which system state data is sent to the support server. Disabling the setting stops system state data being sent.
The frequency with which debug data is sent to the support server. Disabling the setting stops debug data being sent.
Enter proxy server details if you would like the data to be sent through your own proxy server.
Enables SSL verification. Disable if, for example, you are sending the call home data through a proxy server that does not have an SSL certificate recognized by VAST Cluster. VAST Cluster recognizes SSL certificates from a large range of widely recognized certificate authorities (CAs). VAST Cluster may not recognize an SSL certificate signed by your own in-house CA.
