Page 15: File Serving Interfaces
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... -
Page 16: Using Lacp
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...

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... -
Page 21: Aggregate Linux Interfaces
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...
-
Page 23: Typical Non-File Serving Interface Configurations
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... -

Page 26: Routing Overview
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... -
Page 27: Default Gateways
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... -
Page 28: Managing Routes
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... -
Page 29: Understanding Routing By Evs
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.
