Emulex Demonstrates Breakthrough in SAN Connectivity on Intel Platforms Based on the Dual-Core Xeon Processor 5000 with Xen-based Virtual Servers

INTEL DEVELOPER FORUM -- Emulex Corporation (NYSE:ELX), the most trusted name in storage networking connectivity, announced today it will demonstrate the industry's first implementation of N-Port ID Virtualization (NPIV) on Intel platforms, based on the Dual-Core Intel Xeon Processor 5000 sequence (codenamed Bensley), equipped with Intel Virtualization Technology (VT) and the leading-edge Xen open source hypervisor.

Utilizing industry standard NPIV, the Emulex LightPulse(r) Virtual HBA technology provides the foundation for improved SAN management, data protection, and application recovery by enabling virtual servers to use dedicated SAN resources. By incorporating support for the NPIV standard, Emulex's Virtual HBA technology enables server virtualization solutions to fully utilize key SAN management techniques, including zoning, LUN mapping and LUN masking to insure maximum data security.

In Booth No. 301 at the Intel Developer Forum this week, Emulex is showcasing the benefits of its LightPulse(r) Virtual HBA technology, along with leading fabric switch vendors in a Red Hat Linux environment. Integrating Emulex LightPulse Virtual HBA technology within server virtualization solutions provides the capability for each guest operating environment to utilize its own protected view of the SAN, as well as prioritized access to storage bandwidth resources. Additionally, Emulex LightPulse Virtual HBAs enable server virtualization environments, such as Xen, to migrate guest environments seamlessly for load balancing, server maintenance or incident recovery, with immediate reconnection to SAN-based databases and file resources.

"Emulex is at the forefront of delivering NPIV-based HBAs for use within virtual server environments of all types and working with Intel to support its new VT processor family promises deployment of uniquely robust and reliable solutions," said Mike Smith, executive vice president of worldwide marketing at Emulex Corp. "Today's demonstration brings this solution to the next level, by combining it with Intel's breakthrough VT architecture, as well as open-source Linux-based virtualization environment."

"Emulex virtualization technology is a good example of industry innovation in support of server consolidation and other usage models enabled by the Intel Dual-Core Intel Xeon Processor 5000 sequence (Bensley) platform," said Jim Pappas, director of Technology Initiatives, Server Platforms Group, Intel Corporation. "Intel Virtualization Technology and Intel Dual-Core Intel Xeon Processor 5000 platforms deliver the capabilities end-users demand for high reliability and SAN attached deployments."

The Intel Developer Forum demonstration includes an Intel Bensley Platform with Xeon Processors and Intel Virtualization Technology running Xen 3.0 virtualization management with the Red Hat Enterprise Linux 4 operating system. Fibre Channel SAN connectivity is provided via PCI Express interface by Emulex LightPulse Virtual HBAs, running at 4Gb/s speeds. The Emulex LPe11002 PCI Express HBA, coupled with fabric switches from leading vendors, including Brocade, Cisco and McDATA, are featured in the demonstration and provide support for NPIV.
