iSCSI Security

For an iSCSI interface, the iSCSI authentication function can be used when the initiator accesses the target. The
iSCSI authentication function is available for host connections and remote copying.
The Challenge Handshake Authentication Protocol (CHAP) is supported for iSCSI authentication. For CHAP Au-
thentication, unidirectional CHAP or bidirectional CHAP can be selected. When unidirectional CHAP is used, the
target authenticates the initiator to prevent fraudulent access. When bidirectional CHAP is used, the target au-
thenticates the initiator to prevent fraudulent access and the initiator authenticates the target to prevent imper-
sonation.
Note that the Internet Storage Name Service (iSNS) is also supported as an iSCSI name resolution.
Environmental Burden Reduction
The power consumption and the temperature of the ETERNUS AF can be visualized with a graph by using the
ETERNUS SF Storage Cruiser integrated management software in a storage system environment. The ETERNUS AF
collects information on power consumption and the ambient temperature in the storage system. Collected infor-
mation is notified using SNMP and graphically displayed on the screens by ETERNUS SF Storage Cruiser. Cooling
efficiency can be improved by understanding local temperature rises in the data center and reviewing the loca-
tion of air-conditioning.
