1 Overview of XP LUN Configuration and
Security Manager Software
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 XP LUN Configuration and Security Manager Software
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 au-
thentication 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.
