manual abstract
Fibre Channel interface
The XP48, XP128, XP512, and XP1024 disk arrays support these 1 Gbps
and 2 Gbps Fibre Channel interfaces:
• 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 fabric direct 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.
Device emulation types
The disk arrays support the following 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)
allows you to 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 CVS 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
fixed-sized logical disk devices (volumes). (OPEN-V is a CVS-based
custom disk size that you determine. OPEN-L does not support CVS.)
• LUSE (expanded) CVS devices (OPEN-x*n CVS): LUSE CVS
combines CVS devices to create an expanded device. This is done by
first creating CVS custom-sized devices and then using LUSE to
combine from 2 to 36 CVS devices. For example, if three OPEN-9
CVS volumes are combined to create an expanded device, this device
is designated as OPEN-9*3-CVS.
