Preface

This manual briefly explains the operations that need to be performed by the user in order to connect an

ETERNUS DX/AF to a server running Solaris OS via an iSCSI interface.

This manual should be used in conjunction with any other applicable user manuals, such as those for the

ETERNUS DX/AF, server, OS, LAN cards, and drivers.

Refer to "Configuration Guide -Server Connection- Notations" for the notations used in this manual such as

product trademarks and product names. For storage systems that are supported by the OS, refer to the Server

Support Matrix of the ETERNUS DX/AF.

Notes

Note the following issues when connecting the ETERNUS DX/AF to a server.

3.1 LAN Environment Notes

•The ETERNUS DX/AF can be connected to a server via an existing LAN. However, a decrease in LAN perform-

ance may be observed by prior users of said LAN.

•For the iSCSI LAN (used to transfer data), do not set multipath configuration with IP Network Multipathing

(IPMP).

•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.

•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/AF.

•A configuration where multiple LAN ports of a single server are connected to the same network may be

restricted depending on the OS and/or driver specifications. For a multipath connection, connect each path

using different LAN segments by separating the VLAN and so on.

LAN switches should not

be inter-connected (*1)

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.

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).
