The FS4500 Fibre to SATA RAID addresses the high growth, midrange storage market, combining cost-effective SATA technology with Fibre Channel RAID performance and reliability in SAN, DAS, and clustered configurations. It is ideal for reference data and fixed content applications where data availability, throughput and constant access to storage resources are critical. The FS4500 RAID is highly flexible and configurable to adapt to evolving storage requirements with flexible configurations.

Enhanced SATA Reliability
The FS4500 maximizes SATA drive reliability and performance through enhanced thermal and rotational vibration characteristics. The FS4500 has no single point of failure with redundant, hot swappable components and a passive midplane. RAID controllers mask the drives' SATA characteristics, presenting them to the host as high performance FC devices. Dual channel multiplexer (DCM) technology allows dual controllers to access each SATA drive for non-disruptive availability.

Optimal Data Availability and Throughput
The FS4500 provides dual Fibre interfaces to loop, fabric, or point-to-point topologies, and redundant data paths for continuous access to large storage pools. RAID controllers maximize availability, with a "heartbeat" between them for transparent failover/failback in addition to cache coherency and battery back-up. With support for RAID levels 0-5, 10, 30, and 50, one can select the level that best meets application requirements. If a drive fails, the controller automatically rebuilds the data on a global hot spare without impacting system performance. LUN masking, parity-protected data buses, and ECC-protected memory provide maximum availability and continuous data access.

Exceptional Scalability and Investment Protection
Each FS4500 supports up to 12 disk drives or 3 TByte (using 250 GByte drives), in a dense 2U form factor. As storage needs grow, add FS4100 JBOD expansion systems dynamically – up to a total of eight systems (96 drives). A 3Gbit-ready midplane and support for future SATA drives provide investment protection.

Innovative Modular Architecture
The FS4500 is based on advanced Flexible Storage Architecture (FSA). A modular, state-of-the-art design, FSA lets users optimize individual storage solutions to changing application requirements and network environments quickly and economically, by adding component "building blocks." The result is a flexible, universal storage solution for enterprises that addresses current and future needs, and unexpected changes.

Comprehensive Storage Management
Spheras RAIDWatch software enables easy local or remote configuration, monitoring, and tuning of FS4500 solutions. Notification utilities alert administrators to irregularities, while an intuitive interface provides a comprehensive, graphical overview for pre-emptive troubleshooting and system configuration.
