VMware ESX Operating Notes

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
VMkernel (iSCSI Software Initiator)
IP address (1)
IP address for Service Console (2)
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
installed. For details, refer to
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
