SAN Device Virtualization (SDV) FlexAttach Virtualization
Facilitates target and disk management, and only
facilitates disk and data migration.
Facilitates server management and has no
restriction on the end devices used.
WWN NAT and Fibre Channel ID (FC-ID) are
allocated on the virtual device, both primary and
secondary.
WWN and Network Address Transport (NAT) is
allocated to host bus adapter (HBA).
FC-ID rewrite on the switch indicates a
rewrite-capable switch on the path.
No rewrite requirements.
Configuration is distributed. This allows
programming rewrites and connectivity
anywhere.
Configuration distribution is not required for any
of the interface-based configurations.
Configuration is secured to device alias. Does not require device alias for virtual pWWN.
Does not allow automapping to the secondary
device.
Allows automapping to the new HBA. Mapping
process is manual for NPIV.
