From the left navigation menu, select Network Access and then Virtual IP Pools.
-
On the Virtual IP Pools tab, click + Create VIP Pool and complete the fields:
Field
Description
Tenant
Specifies which tenant the VIP pool should serve. A VIP pool can serve a specific tenant or all tenants.
Name
Enter a name for the VIP pool.
Gateway IPv4
Enter an IPv4 address for the gateway.
The gateway IPv4 address is required if your storage clients are on multiple IPv4 subnets and you are routing the client storage traffic through a local gateway.
Subnet CIDR IPv4
Specifies the subnet in Classless Inter-Domain Routing (CIDR) notation for IPv4.
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.
VLAN
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.
CNodes
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.
If Port Membership for the VIP pool is set to RIGHT or LEFT, only right or left ports on the selected CNodes will be used for load balancing in this VIP pool.
Role
Select a role for the VIP pool:
-
Protocols to enable network access to data stored on the VAST cluster.
-
Replication to create a VIP pool dedicated to VAST native replication.
-
Big Catalog to create a VIP pool dedicated to Big Catalog. If a VIP pool with this role exists, the VIPs in this pool are used for Big Catalog queries run from the VAST Web UI. This pool is not required but creating a pool of this role can improve Big Catalog query speed.
VMS Preferred
Enable this setting if you would like the CNodes that are assigned VIPs from this pool to belong to a preferred domain for VMS failover. For more details, see Configuring Network Access.
Port Membership
Determines which port (right or left) in a group of CNodes is allocated to the VIP pool. For more information, see Configuring Network Access. By default, all ports on the pool's CNodes are included in the VIP pool.
Enable L3
Reserved for future use. Must be disabled.
VAST ASN
Reserved for future use.
Peer ASN
Reserved for future use.
VAST DNS Configuration: VIP Pool Domain Name
If you are using the VAST Cluster DNS server, specify a domain name to associate with the VIP pool. The domain suffix is defined in the DNS server configuration, is appended to the VIP pool domain name to form a fully qualified domain name (FQDN). Requests for that FQDN will be allocated VIPs from this pool.
The FQDN formed from the current value entered into the field and the domain suffix is displayed below the field as the DNS Service FQDN.
IP Ranges List
A set of IP addresses that belong to the VIP pool, which can include multiple different contiguous ranges.
For each range, add the Start IP and End IP.
To add a range, click the Add IP Range button.
To remove a range, click the Remove button for that range.
-
-
Click Create.
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.
Caution
Deleting all VIP pools will cause all cluster data to be inaccessible to clients.
To manage virtual IPs, virtual IP pools via VAST CLI, use the following commands.
Tip
For full CLI command syntax, including VAST arguments, enter the command at the CLI prompt in the <command> <subcommand> format provided in the table, followed by ?.
