The XP family of disk arrays supports these Fibre Channel elements:

• Connection speed of 1 Gbps and 2 Gbps

• Short-wave non-OFC (open fiber control) optical interface

• Multimode optical cables with SC or LC connectors

• Public or private arbitrated loop (FC-AL) or direct fabric attach

• Fibre Channel switches

Even though the interface is Fibre Channel, this guide uses the term "SCSI

disk" because disk array devices are defined to the host as SCSI disks.

The XP family of disk arrays supports these device emulation types:

• OPEN-x devices: OPEN-x logical units represent disk devices.

Except for OPEN-V, these devices are based on fixed sizes. OPEN-V

is a user-defined size. Supported emulations include OPEN-3,

OPEN-8, OPEN-9, OPEN-E, OPEN-L, and OPEN-V devices.

• LUSE devices (OPEN-x*n): Logical Unit Size Expansion (LUSE)

devices combine 2 to 36 OPEN-x devices to create expanded LDEVs

larger than standard OPEN-x disk devices. For example, an OPEN-x

LUSE volume created from ten OPEN-x volumes is designated as

OPEN-x*10.

• CVS devices (OPEN-x CVS): Volume Size Configuration (VSC)

defines custom volumes (CVS) that are smaller than normal
