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 Sys­tems to VMware ESX

Use the following URL to determine which ETERNUS DX Disk storage system models may be connected to
VMware ESX:

Search the VMware Compatibility Guide

•

2.4 Virtual Machine

Virtual Machine is a virtual machine created on the VMware ESX server.

Details of how to install an OS on the VMware ESX Virtual Machine may be checked via the following URL:

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

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 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 pre­vent 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).
