Description
Displays the description of the groupnet, subnet, pool, or rule.
Actions
Enables you to view and manage network components.
View / Edit
Displays groupnet, subnet, pool, or rule details.
More
Displays additional actions that you can perform depending on the network component in the row.
  • For groupnets, you can delete the groupnet or add a subnet to the groupnet.
  • For subnets, you can delete the subnet or add an IP address pool to the subnet.
  • For IP address pools, you can delete the pool or add a node provisioning rule to the pool
  • For node provisioning rules, you can delete the rule.
Add a groupnet
Opens a page that allows you to create a groupnet.

Groupnet Settings

Name
Specifies a name for the groupnet that is unique in the system.You can specify only alphanumeric characters, and the name cannot exceed 32 characters.
Description
Specifies a descriptive comment about the groupnet.The description cannot exceed 128 characters.
DNS Servers
Sets a list of DNS IP addresses. Nodes issue DNS requests to these IP addresses. You can click Add a DNS server to specify up to three servers.
DNS Search Suffixes
Sets the list of DNS search suffixes. Suffixes are appended to domain names that are not fully qualified. You can click Add a search suffix to specify up to six suffixes.
Enable DNS resolver rotate
Sets the DNS resolver to rotate or round-robin across DNS servers.
Enable DNS server-side search
Specifies whether server-side DNS searching is enabled, which appends DNS search lists to client DNS inquiries handled by a SmartConnect service IP address.
Enable DNS cache
Specifies whether DNS caching for the groupnet is enabled.

Subnet Settings

Name
Specifies the name of the new subnet.
Description
Adds a descriptive comment about the subnet.The comment can be no more than 128 characters.
IP Family
Specifies either IPv4 or IPv6 as the IP address format for the subnet. You cannot modify the address family once the subnet has been created.
Netmask
Specifies a subnet mask or prefix length, depending on the IP family you selected. For an IPv4 subnet, type a dotted decimal octet (x.x.x.x) that represents the subnet mask. For an IPv6 subnet, type an integer (ranging from 1 to 128) that represents the network prefix length.
Gateway Address
Specifies the IP address of the gateway server device through which the cluster communicates with systems outside of the subnet.
Gateway Priority
Specifies an integer for the priority of the subnet gateway for nodes assigned to more than one subnet. A value of 1 represents the highest priority.
MTU
Specifies the size of the maximum transmission units the cluster uses in network communication. Although OneFS supports both 1500 MTU and 9000 MTU, using a larger frame size for network traffic permits more efficient communication on the external network between clients and cluster nodes. You can select Custom and enter any numerical value.
Custom Value
MTU value must be compatible with your network and the configuration of all devices in the network path.
SmartConnect Service IP
Specifies a SmartConnect service IP address in a subnet that will receive all incoming DNS requests for each IP address pool according to the client connection policy.
VLAN Tagging
Enables a cluster to participate in multiple virtual private networks, also known as virtual LANs or VLANs.
VLAN ID
Specifies an ID number between 2 and 4094. The number must correspond to the VLAN ID number set on the switch.
Hardware Load Balancing IPs
Specifies a Direct Server Return (DSR) for networks that contain a hardware load balancing switch. You can click Add a hardware load balancing IP to specify additional addresses.

Pool Settings

Name
Specifies the name of the new pool. The name can be up to 32 alphanumeric characters long and can include underscores or hyphens, but not spaces or other punctuation.
Description
Adds a descriptive comment about the pool. The comment can be no more than 128 characters.
Access Zone
Specifies the access zone you want associated with the IP address poolClients connecting through IP addresses in this pool can access data only in the associated access zone.
IP Range
Specifies a range of IP addresses you want assigned to the IP address pool in the fields provided. You can click Add an IP range to specify additional address ranges.
Pool Interface Members
Specifies which network interfaces are assigned to the IP address pool. Click Add or Remove to move interfaces in and out of the pool.
Zone Name
Specifies the SmartConnect DNS zone. The SmartConnect DNS zone should be a fully qualified domain name (FQDN).
SmartConnect Service Subnet
Specifies a SmartConnect service subnet that answers all DNS requests on behalf of the pool's SmartConnect DNS zone. The subnet that you designate as the SmartConnect service subnet must have a SmartConnect service IP address configured, and the subnet must be in the same groupnet as the IP address pool.
Client Connection Balancing Policy
Specifies a connection balancing policy for an IP address pool. Options are round-robin, connection count, throughput, or CPU usage. Round-robin is the default setting and the only balancing method available without activating a SmartConnect Advanced license.
IP Failover Policy
Specifies an IP failover policy for an IP address pool. Options are round-robin, connection count, throughput, or CPU usage. To configure an IP failover policy, you must activate a SmartConnect Advanced license.
Rebalance Policy
Specifies a manual or automatic rebalance policy for an IP address pool.
Allocation Method
Specifies whether the IP addresses in an IP address pool are allocated to network interfaces statically or dynamically.
SmartConnect Auto Unsuspend Delay
Specifies the time delay (in seconds) before a node that is automatically unsuspended resumes SmartConnect DNS query responses for the node.
SmartConnect DNS TTL
Specifies either no caching or the time-to-live value for SmartConnect DNS query responses (in seconds). DNS responses are only valid for the time specified.
SmartConnect Zone Aliases
Specifies the SmartConnect DNS zone name for this pool. IP addresses are returned in response to DNS queries to this SmartConnect zone. The value should be a fully qualified domain name. You can click Add a zone alias to specify alternate SmartConnect DNS zone names.
Aggregation Mode
Specifies the method by which OneFS will combine multiple, physical external network interfaces on a node into a single logical interface. Options are round-robin, failover, LACP, and FEC.
Static Routes
Table that enables you to view, add, and remove static routes.
Add a static route
Opens a dialog box that allows you to create a static route.
Subnet
Specifies the IPv4 or IPv6 address of the subnet that traffic will be routed to.
Netmask
Specifies the netmask of the subnet you provided.
Gateway
Specifies the IPv4 or IPv6 address of the gateway that traffic will be routed through.
Add Static Route
Closes the dialog box and adds the new static route to the Static Routes table.
SmartConnect Suspended Nodes
Table that enables you to view, suspend, and resume nodes.
Suspend Nodes
Opens a dialog box where you can select nodes to suspend SmartConnect DNS query responses.
Resume
Resumes SmartConnect DNS query responses for the selected nodes.

Rule Settings

Add Rule
Available on pool rows, opens a page that allows you to create a new node provisioning rule.
Name
Specifies the name of the new node provisioning rule.
Description
Specifies a descriptive comment about the rule.The comment can be no more than 128 characters.
Interface Type
Specifies the network interface type that will be added to the pool when the new node is added to the cluster.
Node Type
Associates a node type with the rule. The rule is applied when a node matching the selected type is added to the cluster. Options are Any, Storage, Accelerator, and Backup accelerator.
