SAN Connection
FC and iSCSI are available as host interfaces. The server and the ETERNUS AF can be connected directly or via a
switch.
Host Interface
This section describes each host interface.
The supported host interfaces vary between ETERNUS AF models. For details about host interfaces, refer to
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
•
16Gbit/s
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
■
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 AF and the connection destinations (switches or servers).
Note that passive type Copper Twinax cables cannot be used.
The following types of host interfaces are available:
