Highlights
- High port density design with up to 40 ports in an efficient, space saving 1U height
- Simple-to-use midrange and enterprise SAN fabric switch for IBM® Power Systems™, IBM System x®, IBM System z® and other server environments
- New levels of performance with 8 Gbps Fibre Channel (FC) technology
- Non-disruptive capacity activation from 24 to 32 to 40 ports with Ports on Demand scalability
- High availability with redundant, hot-swappable fans and power supplies and non-disruptive software upgrades

The IBM System Storage® SAN40B-4 SAN fabric switch provides 24, 32 or 40 active ports and is designed for high performance with 8 Gbps link speeds and backward compatibility to support links running at 4, 2 and 1 Gbps link speeds. High availability features make it suitable for use as a core switch in midrange environments or as an edge-switch in enterprise environments where a wide range of storage area network (SAN) infrastructure simplification and business continuity configurations are possible. IBM Power Systems, System x, System z and many non-IBM disk and tape devices are supported in many common operating system environments. Optional features provide specialized distance extension, dynamic routing between separate or heterogeneous fabrics, link trunking, IBM FICON®, Server Application Optimization (SAO), performance monitoring and advanced security capabilities.
Common features
- Standard configuration includes 24 active ports and capability to attach to hosts, storage devices and other nodes in a SAN fabric.
- The eight-port activation option enables “pay-as-you-grow” scalability to 32 and 40 ports.
- No previous SAN experienced needed to use EZSwitchSetup wizard.
- Little or no management required in small fabric configuration, yet supports robust enterprise-class fabric management practices.
- Advanced Web Tools provides intuitive, graphic switch management.
- Supports IBM POWER Systems, System x, System z and many non-IBM servers.
- Full compatibility with other IBM System Storage and TotalStorage SAN b-type switches, routers and directors and Native Interoperability with current m-type switches and directors helps protect prior SAN investments.
- Ideal for use as an edge switch in larger SANs.
- Optional Fibre Channel Routing enables connection to separate and heterogeneous SAN fabrics.
- Support for FICON, FICON Cascading and FICON Control Unit Port (CUP) is available.
Hardware summary
- 1U 19" packaging designed for rack-mount or table-top.
- Designed for high-performance with 8 Gigabit per second (Gbps) fibre channel ports (requires storage hardware that supports 8 Gbps throughput).
- Speed auto-sensing capabilities provide backward compatibility with 4, 2 and 1 Gbps fibre channel links.
- Supports 8, 4 and 2 Gbps link speeds or 4, 2 and 1 Gbps link speeds depending on which optical transceivers (SFPs) are used.
- Shortwave and longwave SFPs with different speeds can be intermixed in the same switch to meet unique requirements.
- Full Fabric operation and Universal Port Operation are available on all ports.
- Universal Ports self-configure as E, F, FL or M_Ports.
- Optional Integrated Routing allows EX_Ports to be activated on a per-port basis.
- Inter Switch Link (ISL) trunking supports up to eight paths at 8 Gbps to be combined to form a single logical ISL between a pair of switches.
- Advanced Zoning, intelligent management and monitoring with Web Tools, Fabric Watch and Performance Monitor features.
- Non-blocking architecture designed to provide up to 640 Gbps aggregate throughput with a 40-port configuration.
- Standard Advanced Zoning provides hardware-enforced zoning to protect against unauthorized or unauthenticated storage network access, non-secure management access and World Wide Name spoofing.
- IBM SAN b-type switches and directors use common switch firmware, which helps simplify SAN fabric expansion.
- Firmware upgrades are designed to be non-disruptive.
- Remote access and remote management are available through the fabric using GUI, SNMP and Telnet.
