Chapter 2
Checking the Server Environment
Connection to servers is possible in the following environments.
Check the "Server Support Matrix" for server environment conditions.
2.1 Hardware
•VMware ESX connection requires the use of LAN switches.
•Access the following documents or use the "Server Support Matrix" to determine which models are compat-
ible with which servers.
-Search the VMware Compatibility Guide
http://www.vmware.com/resources/compatibility/search.php
2.2 LAN Cards
Refer to the "Server Support Matrix".
2.3 Connection Compatibility of ETERNUS DX Disk Storage Sys-
tems to VMware ESX

Chapter 3
Notes
Note the following issues when connecting the ETERNUS DX Disk storage system to a server.
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 the ETERNUS DX Disk storage system
For example, a total of four IP addresses are required by the following iSCSI connection setup.
Example connection configuration
IP address
for iSCSI port (3)
IP address
for iSCSI port (4)
VMware ESX server
VMkernel (iSCSI Software Initiator)
IP address (1)

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

IP address
for iSCSI port (5)

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 unaf-
fected 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
•For the ETERNUS DX Disk storage system
"RoundRobin" is recommended
-For VMware Infrastructure 3
"Fixed"
•ETERNUS Multipath Driver and GR Multipath Driver do not need to be installed on a VMware ESX Virtual
Machine. The multipath function of VMware ESX provides path redundancy.
For improved system reliability, installing the VMware multipath plug-in for the ETERNUS DX Disk storage
system is recommended. The VMware multipath plug-in for the ETERNUS DX Disk storage system can pre-
vent access from being stopped when a path fails by optimizing the VMware multipath's path fail-over
function for the ETERNUS DX Disk storage system. For details, refer to "6.1.8 Plug-in Settings " (page 30).

3.3 ETERNUS DX Disk Storage System Setup Notes
•To connect a VMware ESX server to the ETERNUS DX Disk storage system, check that the firmware version
matches the version specified in the "Server Support Matrix".
•Assign Affinity Group values starting from LUN0 in ascending order. The server cannot recognize the ETER-
NUS 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 Af-
finity 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 re-
quired for the ETERNUS DX Disk storage system device.
•Details of dynamic recognition of LUNs added while VMware ESX is running are given in the "Chapter
8 Dynamic Recognition of LUNs Added While VMware ESX is in Use " (page 40).
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. Simi-
larly, 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 al-
ready saved data may also be affected.
3.6 LAN Environment 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 that is separate from the business LANs.
•iSCSI LAN redundancy is achieved by the use of multipaths.
•For IP network security, separate the iSCSI LAN 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

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).

3.7 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 manuals
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, DX90 S2, ETERNUS DX400 S2
series, and ETERNUS DX8000 S2 series 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.
