Encrypt storage data flows over long distances without sacrificing performance
Improve load balancing and network resilience with extension trunking to increase
wide area network (WAN) utilization and
help protect against WAN link failures

IT organizations continue to face the unrelenting growth of data being
transferred between data centers, while service level agreement (SLA) and
recovery expectations continue to rise. Meanwhile, enterprise data centers
must also keep pace with the changes driven by virtualized application
workloads. Many organizations are modernizing their disaster-recovery
plans to help ensure continuous availability of their IT systems. In turn,
the storage network infrastructure must continue to evolve to enable fast,
continuous and simple access to mission-critical data from anywhere in
the world.
The IBM® System Storage® SAN42B-R extension switch delivers the
excellent performance, continuous availability of storage extension network and powerful network and application monitoring organizations
need to handle escalating data traffic. The switch includes both Fabric
Vision and Gen 5 Fibre Channel technology—the purpose-built, proven
storage networking infrastructure for delivering outstanding reliability,
simplicity and 16 Gbps performance. In addition, SAN42B-R is designed
to help storage administrators replicate and back up large amounts of data
over WAN quickly, reliably and simply while minimizing operational and
capital expenses.

A purpose-built, scalable and flexible extension
platform
The SAN42B-R switch provides an ideal platform for building a highperformance data center extension infrastructure for replication and
backup solutions. It leverages cost-effective IP WAN transports to extend
