The first step to completing the installation, configure the network settings in Oracle Sun ZFS Storage. The appliance Networking Configuration screen displayed in the below screenshot which will benefit you to create a variety of advanced networking setups out of your physical network ports, including: link- aggregations, virtual LANs (VLANs), and multipath groups. You can define any number of IPv4 and IPv6 addresses for each configuration for use in connecting to the various data services on the system.
The network configuration has three components:
- Devices: Physical network These correspond to your physical network connections or IP on InfiniBand (IPoIB) partitions.
- Datalinks: The basic construct for sending and receiving Datalinks may correspond 1:1 with a device (that is, with a physical network port) or IB partition, or you may define Aggregation, VLAN datalinks composed of other devices and datalinks.
VLANs: Virtual LANs to improve local network security
LACP: Link Aggregation Control Protocol, to bundle multiple network devices to behave as This improves performance (multiplies bandwidth) and reliability (can survive network port failure); however the appliance must be connected to a switch that supports LACP and has it enabled for those ports.
IB Partitions: InfiniBand partitions to connect to logically isolated IB fabric domains
- Interface: The basic construct for IP configuration and Each IP interface is associated with a single datalink, or is defined to be an IP MultiPath (IPMP) group comprising other interfaces.
Configuring a Datalink:
To configure an interface, click the icon next to Datalinks. Then complete the fields in the Datalinks Interface modal dialog box as you see from the below screenshot.
Note: Datalinks are required to complete the network configuration whether or not they apply specific settings to the network devices.
Configuring an Interface:
To configure an interface, click the icon next to Interfaces. Then complete the fields in the Network Interface modal dialog box. The below screenshot displays the Network Interface modal dialog box.
It is important to specify here that IP address must be entered using Classless Inter-Domain Routing (CIDR) notation when entering static addresses. You must include the subnet in the format, 192.168.105.91/24 as an example.
These configure IP addresses via datalinks. They support:
- IPv4 and IPv6
- IPMP—IP MultiPathing—to improve network reliability by allowing IP addresses to automatically migrate from failed to working
Note: When using the BUI to reconfigure networking, the system makes every effort to preserve the current networking connection to your browser. However, some network configuration changes, such as deleting the specific address to which your browser is connected, will unavoidably cause the browser to lose its connection. For this reason, it is recommended that you assign a particular IP address and network device for use by administrators and always leave the address configured. You can also perform particularly complex network reconfiguration tasks from the CLI over the serial console if necessary.
Configure IP Multipathing (IPMP):
IP MultiPathing groups are used to provide IP addresses that will remain available in the event of an IP interface failure (such as a physical wire disconnection or a failure of the connection between a network device and its switch), or in the event of a path failure between the system and its network gateways. The system detects failures by monitoring the IP interface’s underlying datalink for link-up and link-down notifications, and optionally by probing using test addresses that can be assigned to each IP interface in the group, described as follows. Any number of IP interfaces can be placed into an IPMP group so long as they are all on the same link (LAN, IB partition, or VLAN), and any number of highly available addresses can be assigned to an IPMP group.
Each IP interface in an IPMP group is designated either active or standby:
- Active: The IP interface will be used to send and receive data so long as IPMP has determined it is functioning
- Standby: The IP interface will be used to send and receive data only if an active interface (or a previously-activated standby) stops
Note: To configure networking from the CLI, enter the “configuration net” context, and use the “datalinks,” “devices,” and “interfaces” modes. Enter “help” at any point to see a list of available options.
For example, viewing the current configuration:
zfs1:> configuration net
zfs1:configuration net> devices show
DEVICE UP MAC SPEED
nge0 true 0:14:4f:8d:59:aa 1000 Mbit/s
nge1 false 0:14:4f:8d:59:ab 0 Mbit/s
nge2 false 0:14:4f:8d:59:ac 0 Mbit/s
nge3 false 0:14:4f:8d:59:ad 0 Mbit/s
zfs1:configuration net> datalinks show
