AMCC Highlights Innovative SATA RAID Solutions at Intel Channel Conference; AMCC Demonstrates High Performance, High Capacity 3ware 9000 Series SATA RAID Controllers for Intel Product Dealers During National Roadshow.

SUNNYVALE, Calif. -- Applied Micro Circuits Corporation (AMCC) (Nasdaq:AMCC), today announced that it has joined the Intel(R) Channel Conference (ICC) to highlight its industry-leading Serial ATA (SATA) RAID solutions for Intel Product Dealers (IPDs) nationwide. ICC targets system builders and is specifically designed to educate Intel's network of IPDs on the latest related product launches, technology announcements, and program benefits. AMCC will participate in 25 of 35 cities, starting now through May 19.

AMCC SATA controllers enable enterprise-class SATA RAID storage solutions for mid and high-end computing applications.

"ICC attracts thousands of highly qualified attendees specifically looking to evaluate new vendors for the systems that they are tasked with building, installing and managing," said Michael Joyce, Director of Marketing for AMCC Storage. "AMCC provides a comprehensive product family for SATA RAID controllers, and ICC gives us the opportunity to showcase their power, scalability, performance and reliability as well as the real world applications that they enhance and enable."

"ICC targets system builders looking for proven cost-effective, Intel compatible solutions that will perform for their clients day in and day out," said Frank Raimondi, strategic channel alliances manager, Intel Corporation. "AMCC is recognized as an industry leader in SATA RAID and their participation in ICC will help educate IPDs on how 3ware-enabled RAID provides a variety of storage solutions for almost every business and vertical data application."

3ware controllers are based on the company's innovative StorSwitch(TM) switched RAID architecture, that provides scaleable capacity up to 4.8 TB per controller, using 400 GB drives, and total system capacity limited only to available PCI slots. The company's advanced hardware RAID architecture features an on-board processor and an integrated RAID ASIC that offloads RAID controller functions from the host CPU, dedicating the server processing to its core applications and enhancing overall system performance.

For enterprise-class applications, AMCC will demonstrate its StorSave Platform, which combines firmware and a Battery Backup Unit (BBU) to maximize data protection without sacrificing performance. The AMCC StorSave Platform supplies power to the cache memory module in the event of a system power loss and includes proprietary features that utilize a write journaling technique. AMCC delivers this ability for SATA RAID, allowing the controller to use controller and drive's write caching for the best performance while still preventing data loss in the event of a system power failure. When fully charged, the battery preserves the contents of the controller cache memory for up to 72 hours. When power is restored, cached data is then written to the disk array providing uninterrupted data storage.

AMCC will also demonstrate its 9500s 3ware Multi-lane family of RAID controllers for high capacity industrial environments. The Multi-lane controller features a groundbreaking design that increases reliability and simplifies installation via an innovative cabling solution. It includes a highly reliable, locking cable/connector system that combines 4 SATA ports into one on the controller side. 12-port configurations feature 3 integrated connectors and an 8-port configuration offers 2 integrated connectors.
