LAN Environment Notes

Example of a LAN switch connection configuration

Business server A

Card#2

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).

[Management LAN]

The iSCSI LAN and management LAN

segments are kept separate in the iSCSI

LAN switches, helping maintain the security

of each.

Business LAN

Similarly to FC-SAN,

a dedicated LAN is used for iSCSI,

not the business LAN.
