IBM Systems and Technology Data Sheet IBM System Storage SAN42B-R extension ­ switch Extension solution designed to maximize performance and scalability for large, complex environments Highlights Move more storage data between data centers to meet increasing disasterrecovery and business continuity objectives with industry-leading performance and scalability 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
