QLogic to Support Next-Generation Red Hat Enterprise Linux
 
Collaboration with Red Hat Underscores QLogic Commitment to
Driving Virtual Server Adoption
 
ALISO VIEJO, Calif., May 2, 2006 - QLogic® Corp. (Nasdaq:QLGC), the leader
in Fibre Channel host bus adapters (HBAs), stackable switches and blade
server switches, today announced its commitment to support the upcoming
release of Red Hat Enterprise Linux 5 and the virtualization technologies
included in it. QLogic virtualization support will provide Red Hat customers
with a means for deploying and managing reliable storage area networks
(SANs) in virtual server environments.

Integrated virtualization environments will enable users of Red Hat
Enterprise Linux to dramatically increase server utilization, improve
productivity and scalability, and reduce operating costs by consolidating
their workloads onto fewer servers.

³QLogic and Red Hat are working together to provide reliable virtualization
technologies that will result in greatly enhanced efficiencies and cost
savings in the data center,² said Brian Stein, engineering manager, emerging
technologies, Red Hat. ³Our goal is to provide end users with a fully
integrated virtualization environment that will make deployment of
virtualization easy and effective. The interoperability of QLogic drivers
and the future release of Red Hat Enterprise Linux 5 will enable us to
achieve this goal.²

QLogic Fibre Channel HBA drivers have already proven compatible with early
versions of Fedora Core 5, and are fully compliant with XenSource Xen
Hypervisor. QLogic drivers will be bundled with the new Red Hat Enterprise
Linux distribution as standard inbox drivers, as they are in the
current version. 

³Virtualization promises to bring tremendous efficiencies to the server
environment, and QLogic is committed to making virtualization a reality in
the datacenter,² said Amit Vashi, senior director of product marketing,
QLogic Computer Systems Group. ³We are working closely with Red Hat to
develop products and solutions to drive ubiquitous virtualization.²
