AMCC Unveils Storage Technology Roadmap, Affirms Commitment to PCI Express, RAID 6 and SAS to Further Enhance Performance for RAID Controllers.

SUNNYVALE, Calif. -- First Roadmap Deliverable, PCI Express-Based 3ware 9590SE SATA II RAID Controller, Builds Bridge to Future of Serial Storage

E[acute accent]Applied Micro Circuits Corporation (AMCC) (Nasdaq:AMCC) today announced its storage technology roadmap for the year, including its plans for adopting PCI Express, RAID 6, Serial-attached SCSI (SAS), and other performance-enhancing storage technologies. As a first roadmap deliverable, AMCC today released the 3ware(R) 9590SE, an extension of its popular 9550SX family of 3Gb/s SATA II RAID controllers. E[acute accent]The 3ware 9590SE includes PCI Express support, and is based on AMCC's StorSwitch(TM) switched-fabric architecture, a technology that offloads data I/O in the storage subsystem to significantly improve performance, availability and scalability, evidenced by throughput in excess of 800MB/sec RAID 5 reads. As part of its roadmap, AMCC plans to unveil a significant upgrade to its StorSwitch architecture later this year, as well as support for native PCI Express and RAID 6. E[acute accent]"We are taking a bold step in sharing our roadmap, but we feel it is important for our existing and potential customers to understand our product direction as they plan their system designs," said Barbara Murphy, vice president and general manager, AMCC. "Our plans for introducing new storage technologies, including PCI Express and RAID 6, and the evolution of our StorSwitch architecture, all set the stage for our vision for SAS as an infrastructure for high performance SATA solutions." E[acute accent]"AMCC's commitment to serial technologies and advanced RAID features like RAID 6 aligns well with our technology roadmap plans," said Erik Logan, chief technology officer of Seattle-based Pogo Linux Inc. "Our customers are demanding the performance enhancements afforded by PCI Express, and are starting to ask questions about the benefits of RAID 6. While SAS has been a subject of discussion for some time now, we see the technology becoming real later this year." E[acute accent]"AMCC is taking a sensible yet aggressive approach to improving storage network performance and data protection for its customers," said Greg Schulz, founder and storage consultant for StorageIO, based in Stillwater, Minnesota. "AMCC's switched fabric architecture, on top of the performance and cost saving benefits of PCI Express, give storage managers compelling options in protecting their data. RAID 6 and SAS will broaden these options even further to enable highly fault-tolerant, high performance environments."
