  UC DAVIS MEDICALCENTER High-Performance Solution for Cost-Effectively Extending Multiple Applications What Our Customers Are Saying Due to rapid data growth and internal disaster recovery initiatives, the University of California “We selected Ciena’s CN 2000 because of its ability to leverage Davis (UC Davis) Medical Center’s storage our existing infrastructure and meet the strict performance requirements requirements and business needs had begun to in storing and replicating our data between our two sites. Ciena’s strong exceed the capacity of its existing infrastructure, technical expertise and experience in both the storage and optical contained within a single data center. networking environments ensured a quick and easy deployment.” The UC Davis Medical Center, a fully accredited facility with over 600 beds, supports Alejandro Lopez the clinical and research missions of the UC Davis School of Medicine. Located UC Davis Medical Center on 140 acres in central Sacramento, UC Davis Medical Center is the region’s only Level 1 comprehensive adult and pediatric trauma center. To address its storage requirements and business needs, the Medical Center recently built a second data center connected via a dark fiber infrastructure that was limited to only a few pairs of fiber for the networking of storage applications between the data centers. The network needed to support the diverse set of protocols—Gigabit Ethernet (GbE), Fibre Channel (FC) and ESCON®—used by the Medical Center’s storage applications: disk mirroring on the Mainframe and open systems, including IBM Peer to Peer Remote Copying (PPRC) on both Enterprise Storage Server (ESS) and Fibre Array Storage Technology (FAStT); and Network Attached Storage (NAS) extension, tape backup (IBM 3590), and SAN extension (Brocade Inter-Switch Links (ISLs). The Medical Center also required a storage extension solution that provided visibility of their network health and a clear separation between all the different storage networks/applications (i.e., SAN, NAS, Mainframe, and open systems disk mirroring), and the Wide Area Network (WAN). The Medical Center also improved real-time performance monitoring to detect and isolate errors rapidly for immediate response and optimal efficiency. C Case Study

For example, when the Medical dispersed data centers Center migrates their disk mirroring from ESCON to FC, no additional hardware investment will be required on the CN 2000, as protocol changes can be completed > Increased network reliability and availability through software only. > Guaranteed security by Improved Quality of Service (QoS) and Business Continuity Capabilities giving data its own secure deterministic circuit across The Medical Center has also gained guaranteed security of its mission-critical data the network across their redesigned SAN. With the CN 2000, multiple applications can share the same SONET/SDH circuit, while still getting their own physically isolated channel, giving each application its own path across the network. Multiple traffic streams do not share bandwidth, as compared to statistically multiplexed solutions. This allows for high service density with guaranteed loss-free, low-latency performance. Furthermore, the Medical Center gained guaranteed performance of its applications across any distance through Ciena’s flow control technology that extends FC thousands of kilometers, while maintaining maximum throughput.
