CERRITOS, Calif., a
leading supplier of high-performance JTAG development tools for
embedded microprocessors, announced today availability of its
CodeRunner -PPC4XX JTAG Emulator for Applied Micro Circuits
Corporation's (NASDAQ:AMCC) PowerPC 440EP processor , ideally suited
for a wide-range of applications including networking, imaging, and
industrial control. A serial peripheral interface (SPI),
allows full-duplex, synchronous data exchanges with other serial
devices.
Voltaire grid interconnect solutions consist of layer 2-7
multiprotocol switches with integrated InfiniBand, GbE and Fibre
Channel connectivity, grid management and virtualization software,
adapters and other software that enable high performance applications
to run on virtualized server and storage resources.

Integrated with Voltaire GridBoot for Diskless Grids and Clusters

Voltaire's Xen server virtualization solution also offers diskless
boot capabilities which simplifies the deployment and management of
complex grid computing environments.
"The Digi ConnectPort enables 'PC-free' computing by allowing a
host PC to be relocated or even eliminated from high-traffic areas or
environmentally severe locations to a secure back office or other
remote location," said Steve Popovich, vice president and general
manager, Inside Out Networks, a division of Digi International .
"We provide our customers an extensive range of innovative
technology solutions that help convenience store retailers increase
revenue," said Randy Nicholson, president and CEO, AutoGas.

Xen is an open source server virtualization architecture that
allows users to run multiple Virtual Machines (VMs) simultaneously on
the same physical server . Voltaire GridBoot is
complementary to Xen as it enables the complete disaggregation of
compute and storage resources. More information about Voltaire is available at

About AMCC:

AMCC provides the essential building blocks for the processing,
moving and storing of information worldwide. Each VM gets a portion of the server CPU,
memory and I/O from Xen, which dynamically assigns resources to
virtual machines or migrates virtual machines to other servers, if
needed. Using Voltaire GridBoot, customers can
easily move to diskless environments to reduce deployment time and
cluster operating expenses.
