FC, iSCSI, and SAS host interface models are available for the ETERNUS DX60 S2. The server
and the ETERNUS DX Disk storage system can be connected directly or via a switch.
3.1.1

Host Interfaces

This section describes each host interface.
■
FC (Fibre Channel)
FC supports two connection topologies: Fibre Channel Arbitrated Loop (FC-AL) and Fabric.
Direct connections and switch connections to servers are available.
The maximum transfer speed is 4Gbit/s.
■
iSCSI
Direct connections and switch connections to servers are available.
The maximum transfer speed is 1Gbit/s.
In order to maintain iSCSI performance, the iSCSI network should be physically separated from
other types of networks (such as networks for Internet access and file transfers).
• CHAP
CHAP authentication can prevent unauthorized access. The following CHAP authentication
methods are supported:
• Jumbo Frame
Enabling Jumbo Frame makes data transfer more efficient by increasing the amount of data
that can be transferred for each Frame.

Connections
When FC switches are used, zoning should be set for the FC switches to
ensure the security of data.
