Overview
TheSANbloc 2Gb RAID provides high performance and maximum data availability to SAN and clustered environments. The SANbloc RAID can be scaled in multiple dimensions, enabling flexible configuration of capacity, performance, and functionality to match and grow with virtually any application from throughput intensive video and prepress or transaction hungry databases to OLTP. Delivering cost-effective storage to Windows® and UNIX environments, SANbloc RAID provides dual Fibre interfaces to loop, fabric, or point-to-point topologies and redundant loops for continuous access to large data storage pools. Based on a modular, "building block" design, SANbloc offers exceptional scalability in capacity and performance. The SANbloc RAID is designed for maximum availability with redundant, hot-swappable, dual host port RAID controllers, power supplies, power connections, advanced cooling modules, port bypass circuitry, environmental monitoring, and battery-protected mirrored write cache. Features such as multiple target ID support, dual loops with independent paths to all drives, active-active, transparent failover/failback, LUN masking, cache coherency, and parity protected data buses and ECC-protected memory provide maximum data availability and continuous access to data.

Innovative Modular Architecture
The SANbloc RAID is part of a family of network storage storage solutions, based on an advanced Flexible Storage Architecture (FSA). A modular, state-of-the art design, FSA enables users to quickly and cost-effectively optimize individual storage solutions to their changing needs, applications, and network environments by adding component “building blocks.” The result is a truly universal solution for enterprises seeking flexible storage systems that address current and future needs, as well as unexpected changes.

Comprehensive Storage Management and High Availability Software
Spheras Storage Director enables easy local or remote management of SANbloc solutions in heterogeneous, network-centric computing environments. An intuitive console user interface allows administrators to centrally monitor and tune all storage resources across the network as well as configure the system to meet server and applications goals. A comprehensive suite of notification utilities alert administrators to system irregularities. Spheras PATHpilot high availability software provides failover, keeping applications running through fault detection, automatic path failover and I/O rerouting, and ensuring availability of critical information resources. In the event of a path failure, PATHpilot automatically redirects I/O to a redundant path without interrupting data transfer. Balancing I/O over multiple paths enhances resource utilization and data throughput.

Worldwide Service and Interoperability Testing
Adaptec helps ensure the performance and availability of your storage network through our Globalrespond support program. Adaptec offers a complete range of support services – from 24x7 telephone assistance to on-site maintenance – enabling you to tailor a program to meet your needs. Adaptec also works closely with leading manufacturers, testing a variety of storage network technologies and products to ensure seamless interoperability for complete SAN configurations.
