ETERNUS DX Disk storage system
A separate LAN segment is used for each
Server/Storage grouping (*2).
Here, LAN ports 1, 2 and 10 comprise VLAN1,
while LAN ports 3 and 11 comprise VLAN2.
*1: In this system configuration, multipaths provide redundant connections between the servers and stor-
age system. LAN switches #1 and #2 provide physical separation of the network paths.
*2: A separate LAN segment is provided in the LAN switch (using the switch VLAN function) for each group-
ing of business servers and storage systems (equivalent to the FC zones).

The iSCSI LAN and management LAN
segments are kept separate in the iSCSI
LAN switches, helping maintain the security
of each.

Similarly to FC-SAN,
a dedicated LAN is used for iSCSI,
not the business LAN.
