Licensed Feature—Data Migration
1-2 ISR651103-00 C
When using the iSR6152 to connect two Fibre Channel SANs, E_Ports are not
required on the Fibre Channel switches. This allows you to connect multi-vendor
Fibre Channel SANs (switches) without concern for the compatibility of the
E_Ports and N_Ports between different switch vendors.
The iSR6152 also has optional, additional servers and ports to expand
connectivity.
Licensed Feature—Data Migration
The iSR6152 router also provides data migration as an optional, licensed feature.
The iSR6152-based data migration feature is block-based and independent of a
SAN, server, storage protocol (Fibre Channel and iSCSI), and storage vendor.
Because application downtime during data migration is always critical, iSR6152
data migration supports both online (local and remote) and offline data migration
across Fibre Channel and iSCSI storage arrays. Even offline data migration using
the iSR6152 is designed to minimize application downtime by allowing you to
configure all migration related tasks while the application remains online, and to
migrate the data at a very high speed while the application is offline. This feature
is designed such that any person with knowledge of SAN or SAN storage
administration can migrate data.
Fibre Channel over IP (FCIP)
The iSR6152 router supports Fibre Channel over IP (FCIP). The FCIP protocol as
implemented in the router is not guaranteed nor has it been tested to be
compatible with other vendor FCIP implementations. The router supports up to
two FCIP routes; each route requires a dedicated Fibre Channel and GbE port
pair.
Merge Fibre Channel fabrics over LAN or WAN
N_Port to fabric over LAN or WAN
N_Port to N_Port over LAN or WAN
FCIP is generally used as an inter-switch link (ISL) between local and remote
SANs. The ISL enables the SAN fabrics to merge, and requires that both SANs
use compatible Fibre Channel switches (typically from the same vendor).
FCIP can also operate as an N_Port extender to connect a remote Fibre Channel
device into a SAN. This configuration requires a direct connection between the
remote router and the Fibre Channel device.
