Extension Features - IBM SAN512B-6 Installation, Service And User Manual

Extension features

The SX6 Extension blade supports the following extension features.
Note: For full details on extension blade features and configuration, refer to the
Fabric OS Extension Administrator's Guide.
v Connectivity with another SX6 extension blade or the 7840 Extension Switch.
v Multiple logical extension tunnels with maximum tunnel bandwidth up to 40
v Extension trunking feature allows multiple IP source and destination address
v ARL feature meets minimum bandwidth guarantee for each tunnel while
v Hardware-based compression delivers the ability to maximize throughput over
v Key protocol features are enabled in the FCIP implementation to optimize
v Hardware-based IPsec supports mix of secure and non-secure tunnels on the
v FastWrite, Open Systems Tape Pipelining and Advanced Accelerator for FICON
v Extension HCL (Hot Code Load) provides In-service firmware upgrade for
v Built-in WAN link tester generates traffic over an IP connection to test for
v Fabric Vision advanced monitoring provides the following functions:
v Extended distance Fibre Channel supports long distance native FC connectivity.
v Extension tunnels and circuits:
v FCIP and hybrid mode (FC + IP) modes.

– Policy based monitoring monitors extension connectivity and WAN anomalies
using multi-layer metrics.
– Flow monitoring reports IOPS and data rate of individual I/O flows of
inter-DC replication and tape backup operations.
– Flow generator generates FC frames for a defined flow with default or
custom size and pattern and sent across extension tunnel to help validate end
to end network setup and configuration.
– A maximum of 8 circuits can be configured per tunnel.
– A maximum of 20 tunnels (VE_Ports) can be configured for all GbE ports.
– The maximum committed rate of a single circuit is 10 Gbps, whether
configured on a 10 GbE or 40 GbE port.
