LAN switches should not
be inter-connected (*1)
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. 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.

*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).
