5. Connection Configuration

NAS Connection

NAS Connection
Ethernet is used for a NAS interface (NIC-CA). The server and the ETERNUS DX can be connected directly or via a
switch.

NAS Interface (NIC-CA)

This section describes the NAS interface specifications.
Ethernet is a NAS connection interface. An Ethernet network can be accessed as a file server from multiple
connected clients with different operating systems, for the easy sharing of data. The ETERNUS DX has an internal
file system for connection to existing LAN, allowing Ethernet to be installed relatively easily. However, load on
the network will increase, and therefore Ethernet is not suitable for applications that require high transfer rates.
A Unified License is required to install Ethernet host interface. Registering the Unified License to the ETERNUS
DX enables the NAS function.
Ethernet (NIC-CA) host interfaces are available with two different maximum transfer rates (10Gbit/s and
1Gbit/s).
Disable the Spanning Tree Protocol (STP) function for the switch. If the STP function is enabled, connections with
the ETERNUS DX may fail.
Caution
When connecting Copper Twinax cables to Ethernet 10Gbit/s host interfaces, use the Copper Twinax cables
that are supported by both the ETERNUS DX and the connection destinations (switches or servers).
Note that passive type Copper Twinax cables cannot be used.
Operation Mode
•
The Ethernet 10Gbit/s operation mode is 10GBASE-SR. Set "Auto-negotiation" for the transfer rate.
The Ethernet 1Gbit/s operation mode is 1000BASE-T Full Duplex (FULL) or 100BASE-TX Full Duplex (FULL). The
transfer rate can be selected from fixed setting or Auto-negotiation.
Internet Protocol
•
IPv4 and IPv6 are supported.
• VLAN
The tag VLAN function is supported. The number of NAS interfaces, including tag VLANs (VLAN ID), that can be
set for the whole system in the NAS environment is shown in the table below. Distribute VLAN IDs across the
controllers so that VLAN IDs are not concentrated in one controller.
