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
Gbps (FCIP mode) allow for scalable connections between sites.
v Extension trunking feature allows multiple IP source and destination address
pairs (defined as circuits) via multiple 10 GbE or 40 GbE interfaces to provide
high bandwidth extension tunnel and lossless failover resiliency. In addition,
each extension circuit supports four QoS classes (class-F, high, medium and low
priority), each as a TCP connection.
v
ARL feature meets minimum bandwidth guarantee for each tunnel while
making the full utilization of the available network bandwidth without adverse
throughput performance impact at high traffic load.
v Hardware-based compression delivers the ability to maximize throughput over
lower bandwidth links in the wide area network, optimizing the cost efficiencies
of FCIP. The SX6 blade compresses FC frames before they are encapsulated into
FCIP packets.
v Key protocol features are enabled in the FCIP implementation to optimize
performance of extension over IP networks, including WAN Optimized TCP
(WO-TCP), 9K jumbo frame and end-to-end Path MTU auto discovery.
v Hardware-based IPsec supports mix of secure and non-secure tunnels on the
same Ethernet port, jumbo frames, and VLAN tagged connections. The IPsec
function is capable of supporting both IPv4 and IPv6.
v FastWrite, Open Systems Tape Pipelining and Advanced Accelerator for FICON
mitigate the latency effect of a long distance FCIP distance connection over IP
WAN.
v Extension HCL (Hot Code Load) provides In-service firmware upgrade for
supporting 24/7 non-stop business operations
v Built-in WAN link tester generates traffic over an IP connection to test for
maximum throughput, congestion, loss percentage, out of order deliver, latency,
and other network conditions. It helps determine the health of a WAN link
before deploying it for use.
v Fabric Vision advanced monitoring provides the following functions:
– 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.
v Extended distance Fibre Channel supports long distance native FC connectivity.
v Extension tunnels and circuits:
– 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.
v FCIP and hybrid mode (FC + IP) modes.
