Preface Hitachi NAS Platform Network Administration Guide...
EVS fails over onto another node, the IP address moves with the EVS, activating the aggregation on the new node. The server supports static aggregations. It also supports the Link Aggregation Control Protocol (LACP) for dynamic aggregations. Network interfaces Hitachi NAS Platform Network Administration Guide...
Typical LACP configurations Here are three typical configurations when using LACP with NAS servers: • Split-LAG with Layer-2 redundancy • Split-LAG with Layer-2 redundancy and increased bandwidth Network interfaces Hitachi NAS Platform Network Administration Guide...
Page 17
Note: Static aggregation is not supported in a split-LAG scenario. Split-LAG with Layer-2 redundancy and increased bandwidth This scenario includes a link aggregation over four file-serving interfaces for increased bandwidth and increased standby links as shown in the example below: Network interfaces Hitachi NAS Platform Network Administration Guide...
Page 18
This scenario includes a pair or switches connected in such a way as to appear as one logical switch. The NAS servers are configured with a link aggregation over four file-serving interfaces as shown in the example below: Network interfaces Hitachi NAS Platform Network Administration Guide...
VLAN, as it can result in a loss of connectivity. Non-file serving interfaces A NAS server provides two 10/100/1000 Ethernet non-file serving interfaces as follows: • eth1 Network interfaces Hitachi NAS Platform Network Administration Guide...
NAT port. The server then translates this request to the IP address and actual HTTP port of the device on the private management network. Network interfaces Hitachi NAS Platform Network Administration Guide...
The NAS server provides the ability to access the file serving interfaces (agX) from Linux, using a virtual Linux network interface (eth-agX), which is bound to a specific agX interface as shown below: Network interfaces Hitachi NAS Platform Network Administration Guide...
Page 22
It also enables the non-file serving interfaces (eth0 and eth1) and the file serving aggregations to be physically separate while providing Linux access to both sets of interfaces. Example For the scenario below: Network interfaces Hitachi NAS Platform Network Administration Guide...
In this case, eth1 on the NAS and eth1 on the SMU are connected to the same private management network and eth0 on the NAS is optionally connected to the public management network. Network interfaces Hitachi NAS Platform Network Administration Guide...
Successful IP data transmission using jumbo frames depends on the destination IP address or sub-network. The maximum MTU size for a Network interfaces Hitachi NAS Platform Network Administration Guide...
Page 25
• Any IP MTU specified by the selected route • Any IP MTU specified by the MTU command The recommended MTU size is 8972 bytes (in order to compensate for the IP and ICMP headers). Network interfaces Hitachi NAS Platform Network Administration Guide...
HNAS server can route IP traffic in three ways: through Default Gateways, Static Routes, and Dynamic Routes. Default gateways □ Static routes □ Dynamic routes □ Managing routes □ Understanding routing by EVS □ Routing overview Hitachi NAS Platform Network Administration Guide...
Dynamic routes The NAS server supports ICMP redirects and RIP versions 1 and 2, which enable it to dynamically add routes to its route table. ICMP redirects Routing overview Hitachi NAS Platform Network Administration Guide...
Similarly, when a host route is not available, the server selects a corresponding network route or, in the absence of host and network routes, the server sends the packet to a default gateway. Routing overview Hitachi NAS Platform Network Administration Guide...
EVS. If routing by EVS is to be enabled in non-multi-tenant mode, it is necessary to use the routing-by-evs-enable command. See the CLI reference for routing-by-evs commands: • routing-by-evs-enable • routing-by-evs-disable • routing-by-evs-show Routing overview Hitachi NAS Platform Network Administration Guide...
This section contains information on the local name and directory services that the HNAS server can support. These services help the server to support the location, administration, and management of network resources. Name services □ Directory services □ Name and directory services Hitachi NAS Platform Network Administration Guide...
For example, if the server registers its name at bootup, then every 24 hours after the bootup it refreshes its DNS entry. If the server cannot register or refresh its name, it goes into recovery mode Name and directory services Hitachi NAS Platform Network Administration Guide...
NIS (user and group information retrieval, name service resolution, and FTP user authentication), LDAP also provides the following advantages: • Improved accuracy, due to LDAP’s more frequent data synchronization of current and replicated data. Name and directory services Hitachi NAS Platform Network Administration Guide...
Page 33
NIS databases. The server supports LDAP version 2 and 3 (the default is version 3), including two of the most common LDAP service implementations: • Oracle Directory Server • OpenLDAP Name and directory services Hitachi NAS Platform Network Administration Guide...
Using IPv6 This section contains an overview of IPv6 and information on using IPv6 with the NAS server. IPv6 overview □ IPv6 and the NAS server □ Using IPv6 Hitachi NAS Platform Network Administration Guide...
Note: The NAS server does not support SLAAC on file-serving interfaces. Using the SMU with IPv6 It is possible to use the SMU to configure IPv6 addresses for file-serving and non-file serving interfaces, routes and name services. Using IPv6 Hitachi NAS Platform Network Administration Guide...
The Administrator can configure a static IPv6 IP address for an external SMU as shown in the example below or use the SLAAC option where the address is generated from router advertisements. Using IPv6 Hitachi NAS Platform Network Administration Guide...
Page 37
The Administrator can use this address to launch the external SMU GUI and it also enables the external SMU to manage a server with an IPv6 Admin Services Node address. Using IPv6 Hitachi NAS Platform Network Administration Guide...

Round robin load balancing directly contravenes this requirement. However, it can be useful when, for example, running security scan request traffic, by increasing throughput. Configuring link aggregation Hitachi NAS Platform Network Administration Guide...
Click OK to save the changes, or click cancel to return to the Link Aggregation page without saving the changes. Deleting link aggregations Caution: Before deleting an aggregation, remove all IP addresses, ge and tg interfaces associated with the aggregation. To delete an aggregation Configuring link aggregation Hitachi NAS Platform Network Administration Guide...
To remove an existing interface, enter the following command: aggregate-linux-interface-delete <eth-ag-interface> For example: $ aggregate-linux-interface-delete eth-ag1 In this example, the HNAS server deletes an interface named eth-ag1 but ag1 is not removed.

For further details on evs create and evs list, see the CLI Reference. You can also use evsipaddr to associate IP addresses with VLAN interfaces $ evsipaddr -e 1 -a -i 192.168.1.1 -m 255.255.255.0 -p ag1-vlan0433 Configuring VLAN interfaces Hitachi NAS Platform Network Administration Guide...
-x create -p <vlan interface name> For example: ipadv -x create -p ag12-vlan0017 To set the MTU size for a VLAN interface For TCP packets: ipadv --tcpmtu <tcpmtu> -p <VLAN interface name> For example: Configuring VLAN interfaces Hitachi NAS Platform Network Administration Guide...
