v A–Trunk Group 1: ports 0 through 7
v B–Trunk Group 2: ports 8 through 15
v C–Trunk Group 3: ports 16 through 23
Note: ISL Trunking is optional software that allows you to create trunking groups
of ISLs between adjacent switches. For more information about trunking,
refer to the Fabric OS Administrator’s Guide.
Supported optional features
The switch supports the following optional software, which you can activate by
purchasing the corresponding license key:
v Extended Fabric–allows implementation of long distance dynamic (LD) and long
distance static (LS) distance levels. This feature extends SAN fabrics beyond the
Fibre Channel standard 10 km by optimizing the internal switch buffers to
maintain performance on ISLs at distances up to 500 kilometers.
v Fabric Watch–monitors mission-critical switch operations. This feature is
designed to enable real-time proactive awareness of the health, performance, and
security of each switch. It automatically alerts network managers to problems
and helps avoid costly failures by providing:
– Real-time tracking of numerous fabric and switch elements
– Automatic event notifications when switch and fabric elements exceed
thresholds
– Security, availability, and congestion monitoring thresholds and alerts
v Adaptive Networking– provides a set of capability allowing high priority
connections to obtain the bandwidth necessary for optimum performance, even
in congested environments.
v Advanced Performance Monitor–provides Performance Monitoring capability to
help identify end-to-end bandwidth usage by host/target pairs and is designed
to provide information for capacity planning.
v Trunking Activation–designed to enable Fibre Channel packets to be efficiently
distributed across multiple Inter-Switch connections (links) between two SAN
b-type fabric switches, while preserving in-order delivery. ISL Trunking is
supported between any of the supported 2, 4, or 8 Gbps b-type models. Both
SAN b-type fabric switches must have ISL Trunking activated.
v Server Application Optimization (SAO)–designed to bring Quality of Service
(QoS) enhancements for server consolidation and virtualization
In addition, customers can order a set of optional features bundled into one
orderable feature, the B24 Enterprise Package. This bundled feature consists of one
of each of Fabric Watch, Trunking Activation, Advanced Performance Monitor,
Adaptive Networking, and two 8-Port Activations.
