Extension blade overview

The SX6 Extension blade is intended as an extension platform to support Fibre
Channel (FC), FICON, and IP based storage data flows. IBM Extension enables you
to use the existing IP wide area network (WAN) infrastructure to connect Fibre
Channel and IP fabrics. Extension supports applications such as remote data
replication (RDR), centralized backup, and data migration over very long distances
that are impractical or very costly using native Fibre Channel or IP connections.
Extension tunnels, built on a physical connection between two extension switches
or blades, allow Fibre Channel and IP I/O to pass through the IP WAN. The SX6
Extension blade can connect with an SX6 blade in another SAN512B-6 or with a
7840 Extension Switch.
Port and extension blades can an be mixed in in device slots 3–6 and 9–12, but
CR32-8 blades must be installed in slots 7 and 8. You can install a maximum of
four SX6 blades in the device.
The SX6 blade have the following external ports:
v 16 Fibre Channel (FC) SFP+ ports that support Fibre Channel Routing Services
v 16 10 or 1 GbE SFP+ and two 40 GbE QSFP ports. These ports allow connection
Extension blades have the following LED indicators:
v Green blade power LED
v Amber blade status LED
v Bicolor green/amber 40 GbE and 10 or 1 GbE port status LEDs
v Bicolor green/amber FC port status LEDs
