SAN40B-4
High performance, scalability and ease of use for
medium-size SAN environments
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, hotswappable 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 simplication and business continuity congurations 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.
High performance
The IBM System Storage SAN40B-4 switch provides 8 Gbps connectivity on all ports. Each switch port auto-negotiates to 8 Gbps, 4 Gbps,
2 Gbps or 1 Gbps link speeds depending on the speed of the device at
the other end of the link. Up to 640 Gbps throughput is possible with
a 40-port conguration. E_Port connectivity is standard to support
links to other SAN switches, directors and routers via Inter-Switch
Links (ISLs). Up to 8 Gbps throughput at extended distances
of up to 100 km is possible with the Extended Fabric Activation
feature and appropriate distance extension technology.
