Stratix GX in Storage Applications

The storage market is driven by a convergence of storage and networking technologies, information growth, and advances in storage and infrastructure bandwidth. The traditional lines between networking and storage are blurring due to the increased adoption rate of networked storage. There are two main architectures for storage networking: Storage Area Network (SAN) and Network Attached Storage (NAS). The SAN architecture efficiently uses storage assets by decoupling server and storage capacities from a dedicated network. A SAN inserts a dedicated storage network between servers and various storage subsystems. The storage network is composed of switches that connect servers and storage. The NAS architecture uses software to resolve storage challenges. NAS uses existing server technologies and networking technologies (Ethernet) and adds file intelligence. Unlike SANs, where data is managed by traditional operating systems and databases, the NAS software engine manages data and distributes the data over Ethernet wires to users, servers and databases. Storage infrastructure (switch) vendors are challenged with the convergence of SAN and NAS. Users want a virtualized storage repository where they can view and manage all storage assets from one place regardless of technology implementation (NAS or SAN), physical location, or vendor brand. The Stratix GX device family integrates high-speed data transmission and programmable logic for storage switches and storage systems. Built on Altera's new Stratix architecture, Stratix GX devices are available with up to 20 transceiver channels capable of operating at up to 3.2 gigabits per second (Gbps) per channel (3.2-Gbps performance is pending silicon characterization). The Stratix GX solution provides system designers with flexibility, performance, integration, and low power that are not available in any other solution.
