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

•

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-

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 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.

The XP family of disk arrays supports many standard software products that provide host,

application, or I/O path failover and management.
