IBM System Storage SAN40B 4

Tab navigation


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 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 specialised distance extension, dynamic routing between separate or heterogeneous fabrics, link trunking, IBM FICON, Server Application Optimisation (SAO), performance monitoring and advanced security capabilities.

IBM offers a broad systems and storage portfolio combined with decades of experience solving real business problems. With x86, POWER and mainframe systems, disk, tape and network storage systems, IBM can offer the right combination of systems to meet the challenges of your business.


Storage efficiency is more vital than ever. Your disk utilisation rate may be as low as 20% — while the amount of data you are required to store is exploding. IBM Storage can help.


The smarter data centre with improved economics of IT can be achieved by connecting servers and storage with a high-speed and intelligent network fabric that is smarter, faster, greener, open and easy to manage. IBM takes an open, standards-based approach to implement the latest advances in today's flat, converged data centre network designs.


IBM's comprehensive Systems Software solutions help to centralise, streamline and automate your physical and virtual infrastructure, allowing you to optimise workloads and increase your ability to deliver IT services that align with business goals. Let us show you how IBM Systems Software helps you realise the value of IBM smarter computing, by allowing a more effective use of the advanced features in IBM hardware and operating systems.

Integrated solutions

The reality is that you need an IT infrastructure designed for data, tuned to the task and managed in the cloud. If your IT staff spends all of their time managing IT, they won't be working with you to drive innovation. You need your infrastructure to help you in the marketplace, to help you innovate, to help you be more competitive, to help you succeed.

Systems-related services

IBM Systems-related services offers a full range of services to help design, develop, integrate, optimise, validate and deploy comprehensive solutions that support On Demand Business.
