Chapter 3 Notes  
This chapter describes notes when the ETERNUS DX Disk storage systems are connected to  
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 fol-  
lowing iSCSI connection setup.  
Example connection configuration

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 follow-  
ing iSCSI connection setup.

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  
3.5  
SAN Boot Notes  
The ETERNUS DX Disk storage systems do not support SAN Boot when they are connected via  
iSCSI Software Initiator.  
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 con-  
nected 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 con-  
nected 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.

Chapter 3 Notes  
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.

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.  
*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).

Jumbo Frame Setting Notes  
• 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.  
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 man-  
ual.
