LUN Configuration and Security Manager XP user guide for the XP12000/XP10000/SVS200 17

1 Overview of LUN Manager

The XP12000/XP10000/SVS200 arrays integrate the following storage environments to provide

advanced storage solutions:

• Fibre Channel: Fibre Channel is a protocol that enables fast data transfers and can be used for

configuring a storage area network (SAN). To use an array as SAN storage, you should attach host

servers to the array’s Fibre Channel ports.

• iSCSI: internet Small Computer System Interface (iSCSI) is a protocol that enables data transfers

between host computers and large-scale storage devices over an Internet Protocol (IP) network and is

suitable for data transfers between remote locations. To use an array as IP storage, you should attach

host servers to the array’s iSCSI ports.

In an iSCSI environment, the array provides mutual user authentication between hosts and ports using

Challenge Handshake Authentication Protocol (CHAP).

NOTE:

• iSCSI environments that you create with LUN Manager support local connections (that is, hosts

in the same domain can communicate with each other), but neither support inter-domain

connections or external LAN connections.

• When configuring iSCSI environments, you must confirm the operating systems used to run

hosts in the IP network. You can configure iSCSI networks only when each host runs on the

Windows Server 2003, Windows 2000®, or HP-UX 11i operating system. However, user

authentication is not available on hosts running on HP-UX 11i.

• You can connect switching hubs to iSCSI ports, but cannot connect other network relay devices

to iSCSI ports.

• NAS: NAS is a type of storage device attached to a LAN. NAS contains an embedded operating

system and file system to enable file sharing by multi-platform host servers. To use an array as a NAS

storage, you should attach host servers to the array’s NAS ports.
