HOW TO CONFIGURE YOUR SAN40B-4: Walk through this step-by-step guide, choosing appropriate models and options as indicated below:

Step 1: SAN40B-4

The System Storage SAN40B-4 switch is a 40-port auto-sensing 1, 2, 4, or 8 Gbps FC switch delivering the next generation b-type single-chip architecture for FC SANs. With high port density and a slim 1U height, the SAN40B-4 enables the creation of very dense fabrics in a relatively small space. With its flexible Ports on Demand capability scaling from 24 to 32 or 40 ports, the SAN40B-4 provides excellent overall value as the foundation of a SAN with the ability to grow with an organization's SAN needs. This switch is designed to support FICON, FICON Cascading, and FICON Control Unit Port.

SAN40B-4 (The base function of the SAN40B-4 switch includes 24 activated ports, Fibre Channel fabric services, Advanced Zoning, Full Fabric, Fabric Watch, Web Tools, and Enhanced Group Management (EGM). The SAN40B-4 enclosure contains one system board and two hot-swappable, redundant power supply FRUs, each with two integrated fans to generate necessary airflow to cool the whole system.)

Step 3: Optional Features

Description TD #
8-Port Activation License - The SAN40B-4 switch ships with the first 24 ports activated in the base product, with two additional increments of 8 ports that can be enabled on demand. Additional port activation is available with this optional feature to enable additional ports from 24 to 31 (first 8-port increment) or ports 32 to 39 (second 8-port activation). Note the first port is designated as port 0 and the last port is designated as 39. Port activation features do not include fiber optic transceivers; however, all activated ports must be populated with SFPs.
8-Port Activation 95655M
B40/40E Enterprise Package - Enterprise Package offers a convenient method to order a set of optional features bundled into one orderable feature number. This package consists of one of each Trunking Activation, Advanced Performance Monitor, Adaptive Networking, and quantity of two 8-Port Activations.
24E Enterprise Package 95656M
Extended Fabric - Extended Fabric Activation extends SAN fabrics beyond the FC standard 10 km by optimizing the internal switch buffers to help maintain performance on ISLs at distances up to 500 km.
Fabric Watch 95657M
Advanced Performance Monitor - Performance Monitoring Activation 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.
Advanced Performance Monitor 95658M
Trunking Activation - ISL Trunking Activation is designed to enable FC 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.  All the 8 Gbps platforms support a trunk group with up to 8 ports, up to 64 Gbps ISL trunks. The trunking groups are based on the user port number, with contiguous 8 ports as one group.  When connecting the 8 Gbps-capable models to legacy 2 or 4 Gbps-capable b-type fabric switch models, ISL Trunking is supported with link speeds operational at lowest speed and FC packets distributed across ISLs for a combined bandwidth of up to 8 or 64 Gbps.
Trunking Activation 95659M
Adaptive Networking - Adaptive Networking provides a set of capabilities allowing high-priority connections to obtain the bandwidth necessary for optimum performance, even in congested environments. The Quality of Service (QoS) SID/DID Prioritization and Ingress Rate Limiting features are the first components of this license option and are available on all 8 Gbps platforms.
Adaptive Networking 95660M
FICON w/ CUP Activation - FICON with CUP Activation is designed to provide in-band management of the supported SAN b-type switch, router, and director products by System Automation for z/OS from IBM System z10, z9 EC, z9 BC, and zSeries 990, 900, 890, and 800 servers. To enable in-band management on multiple switches and directors, each switch, router, or director must be configured with the appropriate FICON CUP feature. This support is designed to provide a single point of control for managing connectivity in active FICON I/O configurations. System Automation for OS/390 or z/OS can now concurrently manage IBM 9032 ESCON Directors, as well as supported SAN b-type switch and director products with FICON.
FICON w/ CUP Activation 95661M
Integrated Routing - Integrated Routing allows any port in a SAN40B-4 to be configured as an EX_port supporting FCR. Integrated routing is FCR support on the 8 Gbps ports as a native capability, hence they are referred to as native EX_ports. This eliminates the need to add a routing blade or use the SAN18B-R for FCR purposes, and also provides double the bandwidth for each FC Router connection when connected to another 8 Gbps-capable port.
Integrated Routing 95663M
