*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.
Table 77 Ethernet Frame Capacity (Jumbo Frame Settings)
Jumbo Frame settings Ethernet frame capacity
Enabled Up to 9000 bytes
Disabled Up to 1500 bytes
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.
