Introduction to the SV Router FC-FC 3

Drive Information
The drive configuration created in SV SAN Builder applies globally within a SAN. This global
mapping table is shared between all SV Routers in the SAN, so SV SAN Builder only needs to
communicate with one SV Router FC-FC 3 to access this data.
Physical Drive
This is an individual disk drive that exists in the storage loop. Physical drives also can have
mapped attributes.
Logical Drive
Logical drives are created from physical drives, have a single ID and LUN, and are viewed by
the host as one single drive. These are the multipath drives
Simple Drive
Simple drives can be used as spare drives or storage drives, be combined with other simple
drives to form logical drives, or can be added to a disk pool to create standby drives.
Simple drives can be mapped or unmapped. Mapped simple drives have a LUN and can be
viewed by the host. Unmapped simple drives are invisible to the host but visible to Vicom
software or hardware.
General Spare
A general spare drive replaces any failed mirror drive member.
Note:
The general spare drive’s capacity must be equal to or greater than that of the member drive it is
replacing. If the spare is smaller than the drive it is replacing, the spare will be rejected. Should
the spare be larger, the extra storage will not be used.
