Broadcom's ServerWorks is First to Integrate Gigabit Ethernet Into Core Logic for Intel[R]-Based Servers

9/4/2002 - ServerWorks, a Broadcom® company and the leading independent supplier of high-performance SystemI/OTM integrated circuits for servers, workstations and storage platforms, announced it has begun sampling the ChampionTM Ethernet I/O Bridge (CIOB-E), the first core logic to integrate Gigabit Ethernet (GbE) on a chip. The new ServerWorksTM I/O bridge can be used with all versions of the company's Grand ChampionTM SystemI/O core logic. ServerWorks' SystemI/O core logic technology manages the flow of data to and from a system's processors, memory and peripheral input/output (I/O) devices.

The CIOB-E includes two integrated GbE adapters, each capable of full- duplex operation at speeds up to one Gigabit/second, along with a PCI-X bus controller. The tight integration of these features improves system performance and reduces system cost. The CIOB-E eliminates the need for discrete GbE interfaces, reduces system board real estate requirements, and facilitates the use of GbE in space-constrained server blade applications.

"Gigabit Ethernet on an I/O bridge represents a major milestone for the convergence of computing and communications technology," said Raju Vegesna, President and CEO of ServerWorks. "Integrating high-performance communications technology directly into the core logic reduces costs, increases bandwidth and standardizes Gigabit Ethernet as the primary connection in all servers."

Gigabit Ethernet, the De Facto Standard for Servers
The Ethernet controllers on the CIOB-E contain a full range of features that optimize system performance and manageability. Each Ethernet Media Access Control (MAC) unit includes two high-speed MIPS® processor cores that can be utilized for advanced packet filtering and CPU off-loading. The CIOB-E's MAC uses the same set of drivers as Broadcom's highly successful NetXtremeTM family of GbE controllers. In addition to the dual MAC capability, the CIOB-E integrates two Ethernet physical access layer interfaces (PHY) that operate with standard twisted pair wiring at speeds of 10, 100 or 1000 Megabits/second. An alternative version of the CIOB-E, known as the CIOB-ES, supports differential signaling to an external SERDES interface for optical and backplane applications.

The CIOB-E is the first ServerWorks product to leverage Broadcom's technology and market leadership position in the Gigabit Ethernet MAC, Gigabit PHY and SERDES arena. Other important technological resources that ServerWorks has garnered through its relationship with Broadcom include TurboTeamingTM technology, which provides for a 50% performance gain when two Ethernet ports are used in conjunction with one another. A dual-Ethernet board configuration is often used in rack mount servers and blade-based servers. Also, ServerWorks customers benefit from a host of drivers and manageability software including Intelligent Platform Management Interface (IPMI) 1.5 and Alert Standard Forum (ASF), which aid in remote diagnostics and control functions.

"The high-end server market is hungry for innovations to drive growth. As the market continues shifting to GbE, server vendors that move quickly to integrate the technology onto the system board will be better positioned to capitalize on the trend."

Nathan Brookwood, Principal Analyst, Insight64
"The introduction of the ServerWorks CIOB-E once again demonstrates how Moore's Law reshapes markets. It used to be easy to tell the difference between server suppliers and communications system suppliers. Now, as Gigabit Ethernet moves into server core logic, these markets will converge. Participants that lack the IP resources and technology to combine these capabilities will find themselves at a disadvantage going forward."

Vernon Turner, Group Vice President, Global Enterprise Server Solutions, IDC
"Integrating GbE onto the system board is one way that server manufacturers can differentiate their products and take full advantage of a strong growing market. We fully expect that this announcement will lead to new server form factors and raise the bar for the industry standard server suppliers."

Jeffrey Hewitt, Principal Analyst, Servers Worldwide, Dataquest
"The trend of integrating functionality such as GbE into core logic can help to fuel the growth of blade servers and other high-density systems by reducing costs and saving valuable board space. ServerWorks' CIOB-E is designed to be a flexible option for OEMs, with its dual-MAC capability and alternative versions that support optical and backplane applications."

Michael Peterson, President, Strategic Research Corporation
"ServerWorks continues to leverage the critical role of core logic in maximizing server performance and scalability, empowering OEMs to implement bold innovations in system design. The CIOB-E, with integrated GbE and iSCSI capability, revolutionizes the blade server architecture and will have a great impact on the market."

The Champion Ethernet I/O Bridges (CIOB-E and CIOB-ES) are currently sampling, and volume shipments are scheduled to begin in the fourth quarter of 2002.
