Fibre Channel interface

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 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 XP family of disk arrays supports these device emulation types:
•
OPEN-3/8/9/E/L/V 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-
2 to 36 OPEN-x devices to create expanded LDEVs larger than standard
OPEN-3/8/9/E/L/V 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 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 many standard software products that provide host,
application, or I/O path failover and management.
