■
iSCSI
Direct connections and switch connections to servers are available.
The following types of host interfaces are available:
iSCSI 10Gbit/s
•
One of the following transfer rates can be specified:
10Gbit/s
-
1Gbit/s
-
•
iSCSI 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).
Operation Mode
•
The iSCSI 10Gbit/s operation mode is 10GBASE-T.
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 sup-
ported:
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 trans-
ferred for each Frame.

Jumbo Frame settings
Enabled
Disabled
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 re-
quired.
Internet Protocol
•
IPv4 and IPv6 are supported.
Data Center Bridging (DCB)
•
iSCSI 10Gbit/s interfaces support the Data Center Bridging (DCB) function.
DCB is an enhanced function of traditional Ethernet and a standard for Fabric connections in data centers. The
DCB function allows connections to Converged Enhanced Ethernet (CEE) environments.
