the server via iSCSI interface.
3.1 Connection Notes
3.1.1 For VMware vSphere
Dedicated IP addresses must be allocated to the iSCSI LAN. An IP address must be allocated to
each VMkernel that corresponds to an iSCSI Initiator, and a LAN card and VMkernel must be
connected via a virtual switch. For example, a total of four IP addresses are required by the following iSCSI connection setup.

3.1.2 For VMware Infrastructure 3
Dedicated IP addresses must be allocated to the iSCSI LAN. An IP address must be allocated to
each VMkernel that corresponds to an iSCSI Initiator, and a LAN card and VMkernel must be
connected via a virtual switch. For example, a total of six IP addresses are required by the following iSCSI connection setup.
Example connection configuration
3.2 VMware ESX Operating Notes
• Refer to the following web-site for the number of LUNs that VMware ESX can recognize.
http://www.vmware.com/support/pubs/
• When Windows® is used on the Virtual Machine, the registry will need to be modified after
Windows® is installed. For details, refer to "Chapter 7 Virtual Machine" (page 38)
.
• The VMware ESX multipath function supports path failover, meaning that server access can
continue unaffected by any problems that might arise in the iSCSI cables or LAN switches.
It should be noted that path failover can fail to occur when multiple SCSI sense codes are
repeatedly and simultaneously received.
• Set the "Path Selection Policy" (per-LUN) as follows:
- For VMware vSphere: "RoundRobin" is recommended
- For VMware Infrastructure 3: "Fixed"
• ETERNUS Multipath Driver and GR Multipath Driver do not need to be installed on the
VMware ESX Virtual Machine. Multipath function of VMware ESX provides path redundancy.

Chapter 3 Notes
3.3 ETERNUS DX Disk Storage System Setup Notes
3.3 ETERNUS DX Disk Storage System Setup Notes
• When connecting the ETERNUS DX Disk storage system to VMware ESX, check that the
firmware version is as specified in the "Server Support Matrix".
• Assign Affinity Group values starting from LUN0 in ascending order.
The server cannot recognize the ETERNUS DX Disk storage system LUNs if some other
assignment order is used.
• When LUNs are shared among multiple physical servers (in a VMotion configuration, for
example), an Affinity Group mapping should be used to ensure that each shared LUN is
assigned the same LUN number across every physical server.
• When connecting to VMware ESX with multiple paths sharing a single LUN, a Reset Group
setting is required for the ETERNUS DX Disk storage system.
3.4 SAN Boot Notes
The ETERNUS DX Disk storage systems do not support SAN Boot when they are connected via
iSCSI Software Initiator.
3.5 Server Startup and Power Supply Control Notes
Before turning the server on, check that the ETERNUS DX Disk storage systems and LAN
switches are all "Ready". Specifically, check that the Ready LED is lit for ETERNUS DX Disk
storage systems. If the server is turned on and they are not "Ready", the server will not be able to
recognize the ETERNUS DX Disk storage systems.
Also, when the ETERNUS DX Disk storage system power supply is being controlled by a connected server, make sure that the ETERNUS DX 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 DX Disk storage systems, and already saved data may also be affected.

The iSCSI LAN and management LAN

Similarly to FC-SAN,
a dedicated LAN is used for iSCSI,

3.6 LAN Switch Connection Notes
3.6 LAN Switch Connection Notes
• Since an iSCSI LAN handles large amounts of data (traffic volumes) like an FC-SAN, the
iSCSI LAN must have its own switch and be a dedicated LAN separate from the business
LANs.
• iSCSI LAN redundancy is achieved by the use of multipaths.
• For IP network security, the iSCSI LAN assumed to be a dedicated LAN separated from the
management LAN (for administration).
• The iSCSI LAN must be configured as a dedicated LAN for each path from a server to the
ETERNUS DX Disk storage system.
Example of a LAN switch connection configuration
ETERNUS DX Disk storage systems User’s Guide -Server Connection- (iSCSI) for VMware® ESX
*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).

• To enable Jumbo Frame, all the connected devices must support Jumbo Frame. Set the
appropriate values for various parameters (such as the MTU size) on each connected device.
• For details about how to set Jumbo Frame for a LAN card and LAN switch, refer to the
VMware ESX and each device's manuals. Rebooting the server may be required to apply the
new settings.
• The MTU size that is supported by the ETERNUS DX60/DX60 S2, DX80/DX80 S2, and DX90
S2 is 9000 bytes.
3.8 LAN Switch Setting Notes
When using a LAN switch that supports the flow control function, disable the flow control function
according to the following notes:
• For access paths that use iSCSI, disable the flow control function on the sending and
receiving ends of the port.
• When a cascade connection is used to connect to LAN switches, disable the function for the
LAN switch that is directly connected to the ETERNUS DX Disk storage system.
For details on how to set the flow control function of the LAN switch, refer to the LAN switch manual.

6 Check the [Path Selection] for all the LUNs in the ETERNUS DX Disk storage
system.
When the VMware ESX recognizes the LUN, an active path for each LUN is automatically
specified. Even though [Path Selection] is set to [Most Recently Used (VMware)],
changing the [Path Selection] for all the LUNs to [RoundRobin] is recommended.
