SVS200 LUN Manager and Volume Manager (T1714-96015, October 2007)

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.

•Whenconﬁguring 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

notavailableonhostsrunningonHP-UX11i.

• 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.
