Hot-Plug Blade Server Patents Issued to Egenera

April 26, 2006 by Jeff Shepard

Egenera Inc. has received three patents related to the management of hot-pluggable blade servers in a datacenter environment. The U.S. Patent and Trademark Office has issued U.S. Patent No. 6,927,974 entitled "Simplified Power and Data Connector for Use with Chassis System that Houses Multiple Processors," and U.S. Patent No. 6,953,232 entitled "Latching Mechanism for Securing a Computer Component into a Housing," and U.S. Patent No. 7,032,108 entitled "System and Method for Virtualizing Basic Input/Output System (BIOS) Including BIOS Run Time Services."

The newly patented interconnect technology, referred to as the BladeMate™ system, integrates high-speed fabric connections, blade management and power distribution in a hot-plug connection scheme. Multi-level alignment between mating connector components ensures highly reliable operation. This embedded connection technology allows Egenera to deliver blades based on virtually any processor architecture.

Working in concert with BladeMate is the newly patented BladeLatch™ system, a handle mechanism for easily installing, securing and removing blades from the Egenera BladeFrame® chassis. Together, these technologies enable Egenera customers to leverage advances in processor technology by upgrading blades without disrupting overall datacenter operations.

Egenera's BIOS technology virtualizes the operations provided by standard server BIOS, allowing those I/O operations to be performed to devices that are not physically attached to the server. The virtual BIOS accesses virtual console and virtual storage resources necessary to transform diskless, stateless Egenera® Processing Blade™ modules into virtual servers. This technology is a key enabler for virtualizing server configuration while providing the standard BIOS interfaces required by enterprise server operating systems.

"This work is a testament to the creativity and innovation of Egenera's engineering team," noted Pete Manca, senior vice president, Engineering, at Egenera. "These three new patents contribute to Egenera's leadership position in the market for utility computing solutions. Likewise, our customers benefit from unique, value-added capabilities they can't get anywhere else. With several other patents pending, Egenera is committed to remaining on the leading edge of datacenter virtualization technology."
