Broadcom Introduces Industry's First Serial RAID-on-Chip Device

10/28/2004 - Broadcom Corporation (Nasdaq: BRCM), a leading provider of highly integrated semiconductor solutions enabling broadband communications, announced the availability of the industry's first Serial RAID-on-Chip (RoC) device that brings a level of data reliability and availability to cost- sensitive server and storage platforms that were typically available only with high-end enterprise-class storage systems. Broadcom's new RoC device is designed to be shipped as a standard offering with all classes of storage subsystems including external RAID controller cards, chassis-based servers, rack-mounted servers and blade servers.

The introduction of the industry's first Serial-ATA (SATA) RAID-on-Chip device provides a major benefit for IT professionals in the high-volume, low- end server segment requiring cost-effective RAID solutions that take advantage of low cost, high capacity SATA disk drives. The Broadcom® BCM5773 RoC device combines storage processing functions with I/O bridging and advanced software technologies that enable system designers to effectively address cost and space concerns through the implementation of RAID-on-motherboard (RoMB) solutions using SATA disk drives compared to more costly multi-chip or host bus adapter (HBA) solutions.

The exponential growth of disk drive capacity has created significant reliability and performance issues for users of today's storage products that can be addressed with RAID technology. The data loss due to a drive failure continues to increase proportionally with the growth of disk drive capacity, creating ever greater needs for redundancy and data recovery.

In addition, the sustained data throughput of disk drives has not kept up with disk drive capacity growth, resulting in diminishing performance per unit of storage. While enterprise customers have adopted advanced forms of RAID technology (i.e. RAID5) to solve these reliability and performance problems, the high cost and complexity of these RAID solutions have led to limited adoption by cost sensitive customers. As small-to-medium-sized businesses (SMBs) continue to adopt SATA disk drives for storing business critical information, the requirement for cost-effective, high performing RAID solutions that boost reliability and performance becomes even more critical.

"RAID5 fault tolerance in low-end servers is an IT manager's goal, but has always been cost prohibitive. Bringing RAID5 capabilities to low-end and mid- range servers is great for cost-sensitive businesses who need highly-effective data protection," said Tony Asaro, Senior Analyst, Enterprise Strategy Group. "Broadcom is one of few semiconductor providers that can offer RAID storage to all levels of businesses, including SMBs, who can now implement enterprise- level RAID features without the cost and IT-intensive processes that have kept RAID from more widespread use."

The BCM5773 RoC device integrates several functions that previously existed as discrete components:

This high level of integration simplifies RAID on motherboard designs by reducing multiple board level components while reducing power consumption. This is achieved by eliminating multiple interfaces between discrete devices, contributing to significant cost and space savings for server and storage OEMs looking to offer enterprise-class RAID functionality to their cost-sensitive SMB customers.

Additional enterprise-class RAID functionality is provided by Broadcom's highly portable XelCore RAID software. The XelCore software provides support for all popular RAID levels, as well as enterprise-class features such as online capacity expansion, controller spanning, online RAID level migration, and the ability to create storage arrays that span multiple controllers without having to bring the system down.

"The BCM5773 RoC device, combined with the XelCore RAID software, represents a total storage solution and introduces a powerful new paradigm in storage I/O solution design," said Tom Marmen, Vice President and General Manager of Broadcom's Storage Line of Business. "System designers are now able to develop a completely new generation of server platforms, with integrated storage capabilities for emerging high-speed serial interfaces like SATA, while reducing design and qualification time."
