Fibre Channel int
erface
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
Even though the i
nterface is Fibre Channel, this guide uses the term “SCSI disk” because
disk array devi
ces are defined to the host as SCSI disks.
For information about sup ported fiber cables, Fibre Channel adapters, and switches,
contact your H P service representative.
Device emulation types
The XP family of disk a rrays suppor ts 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-K,
OPEN-L, OPEN-M 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 O PEN-x LUSE volume created from ten OPEN-x
volumesisdesignatedasOPEN-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.
Failover
The XP family of disk arrays supports ma ny standard software products that p rovide host,
appl
ication, or I/O path failover and management.
