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 Optimisation (SAO), performance monitoring and advanced security capabilities.
Common features
- Designed to provide a highly robust 8 Gbps platform in two modular form factors for enterprise data centres supporting open system and IBM System z® environments
- Designed to maximize chassis bandwidth, performance and port density with the industry's first and only 64-port Fibre Channel blade
- Designed to deliver exceptional performance when compared to alternate offerings, aiming to meet data growth and access demands, expand virtualisation and consolidate resources
- Designed to improve energy efficiency when compared to alternate offerings, enabling data centres to support more server and storage equipment
- Designed to provide a high-density, multiprotocol platform for consolidating server connectivity using emerging CEE and FCoE networking technology
- Designed to protect data against disasters and outages with plug-in blade for long-distance SAN extension
