The SAN42B-R enables you to move more storage data between data centers to meet increasing disaster-recovery and business continuity objectives with industry-leading performance and scalability. Twenty-four 16-Gbps Fibre Channel/FICON ports, sixteen 1/10-GbE ports and two 40-GbE ports provide the bandwidth, port density and throughput required to help maximize application performance over WAN connections.

Comprehensive set of advanced services

The SAN42B-R base configuration offers a comprehensive set of advanced services, including: Fibre Channel over IP, IP Extension, Fabric Vision, Extension Trunking, Adaptive Rate Limiting, IPSec, compression and Extended Fabric. Optional value-add licenses for Integrated Routing (FCR), FICON Control Unit Port (CUP) and Advanced FICON Accelerator are also available to help address a variety of storage networking challenges.

Non-disruptive firmware updates

SAN42B-R combines enterprise-class availability with innovative features and non-disruptive firmware updates to support always-on business operations and maximize application uptime for Gen 5 and Gen 6 Fibre Channel and FICON platforms. These capabilities enable a high-performance and highly reliable network infrastructure for disaster-recovery and data protection.

Integrated architecture and management

The SAN42B-R extension solution utilizes the same Fabric Operating System that supports the entire IBM System Storage b-type Fibre
Channel family. This helps ensure continuous interoperability with advanced features supported through FOS version releases. It also provides familiar tools for you to easily perform management and administrative tasks, and optional FICON CUP capabilities to enable legacy management application for supporting FICON environments.
