Example LAN switch connection configuration
*1: In this system configuration, multipaths provide redundant connections between the servers and
storage 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
grouping of business servers and disk storage systems (equivalent to the FC zones).
3.2 Server Startup and Power Supply Control Notes
Before turning the server on, check that the ETERNUS Disk storage systems and LAN switches
are all "Ready". If the server is turned on and they are not "Ready", the server will not be able to
recognize the ETERNUS Disk storage systems.
Also, when the ETERNUS Disk storage system power supply is being controlled by a con-
nected server, make sure that the ETERNUS Disk storage system does not shut down before
the connected servers. Similarly, the LAN switches must also be turned off after the connected
servers have been shut down.
If turned off, data writes from the running server cannot be saved to the ETERNUS Disk storage
systems, and already saved data may also be affected.

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.
