5. Connection Configuration
SAN Connection
The following types of host interfaces are available:
Table 76 Types of Host Interfaces
Type (operation mode)
iSCSI 10Gbit/s
(10GBASE-SR/10GBASE-CR) (*1)
iSCSI 10Gbit/s
(10GBASE-T)
iSCSI 1Gbit/s
(1000BASE-T Full Duplex (FULL))
¡: Supported —: Not supported
*1: 10GBASE-CR is a form of communication that uses Twinax cables and is 10GBASE-SR-compliant.
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).
• Operation Mode
The iSCSI 10Gbit/s operation mode is 10GBASE-SR, 10GBASE-CR, or 10GBASE-T.
10GBASE-CR is a form of communication that uses Twinax cables and is 10GBASE-SR-compliant.
The iSCSI 1Gbit/s operation mode is 1000BASE-T Full Duplex (FULL).
CHAP
•
CHAP authentication can prevent unauthorized access. The following CHAP authentication methods are
supported:
- Unidirectional CHAP
- Bidirectional CHAP
Tag VLAN
•
The tag VLAN function is supported. 16 tags (VLAN ID) can be used for each port.
• Jumbo Frame
Enabling Jumbo Frame makes data transfer more efficient by increasing the amount of data that can be
transferred for each Frame.

Caution
Server-side CPU load can be reduced by using Jumbo Frame. However, I/O performance may be reduced
by 10% to 30%.
Security Architecture for Internet Protocol (IPsec)
•
The IPsec function is not supported. Connect the server using a LAN switch that has the IPsec function as
required.
