San Connection; Host Interface - Fujitsu ETERNUS DX S5 Series Design Manual

5. Connection Configuration

SAN Connection

SAN Connection
FC, iSCSI, and SAS are available as host interfaces. The server and the ETERNUS DX can be connected directly or
via a switch.

Host Interface

This section describes each host interface.
The supported host interfaces vary between ETERNUS DX models. For details about host interfaces, refer to
Interface" (page 284).
When switches are used, zoning should be set for the switches to ensure the security of data.
■
Fibre Channel (FC)
The FC connection topologies that are supported are Fabric and Fibre Channel Arbitrated Loop (FC-AL). Direct
connections and switch connections to the servers are available.
The following types of host interfaces are available:
32Gbit/s (*1)
•
• 16Gbit/s
8Gbit/s (*2)
•
*1: Supported by the ETERNUS DX except the ETERNUS DX60 S5.
*2: This host interface is supported only for the ETERNUS DX60 S5.
The transfer rate can be selected from the following fixed speeds or set to Auto-negotiation.
●
For FC 32Gbit/s Interfaces
• 32Gbit/s
16Gbit/s
•
8Gbit/s
•
●
For FC 16Gbit/s Interfaces
• 16Gbit/s
8Gbit/s
•
• 4Gbit/s
●
For FC 8Gbit/s Interfaces
8Gbit/s
•
4Gbit/s
•
■
iSCSI
Direct connections and switch connections to servers are available.
Caution
When connecting Copper Twinax cables to iSCSI 10Gbit/s host interfaces, use the Copper Twinax cables
that are both supported by the ETERNUS DX and the connection destinations (switches or servers).
Note that passive type Copper Twinax cables cannot be used.
