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 or 10GBASE-CR.
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 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.
Table 48 Ethernet Frame Capacity (Jumbo Frame Settings)
Jumbo Frame settings
Ethernet frame capacity
Enabled
Up to 9000 bytes
Disabled
Up to 1500 bytes
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.
■
FCoE
This host interface is supported only for the ETERNUS DX500 S3/DX600 S3.
Fabric is supported as a connection topology. The transfer rate is 10Gbit/s. When using an FCoE interface, con-
nect the ETERNUS DX to the FCoE switch. Direct connections to servers are not supported.
