                Emulex Corporation to Acquire Sierra Logic, Inc.

     Acquisition Expands Company's Position in Embedded Storage Components
            Market and Delivers End-to-End Multi-Protocol Solutions

                ------------------------------------------------

     COSTA MESA, Calif. and ROSEVILLE, Calif., August 29, 2006 - Emulex
Corporation (NYSE:ELX) and Sierra Logic, Inc. announced today the two companies
have signed a definitive agreement whereby Emulex will acquire Sierra Logic,
Inc., a leading provider of embedded ASIC components and firmware solutions for
enterprise storage systems.

     The acquisition of Sierra Logic expands Emulex's position in the market
for embedded multi-protocol storage products. Sierra Logic's current product
portfolio, which includes embedded bridges and routers, enables connectivity of
low-cost Serial Advanced Technology Attachment (SATA) disk drives within Fibre
Channel-based enterprise storage systems. Further, these products are deployed
by the world's leading OEMs in conjunction with Emulex's existing InSpeed
embedded switches and I/O Controller (IOC) products to provide a fully
complementary embedded end-to-end solution.

     "This acquisition solidifies Emulex's embedded multi-protocol strategy and
is another critical step toward becoming the market leader in the end-to-end
embedded storage components market. The expansion of our embedded product
portfolio also provides incremental revenue opportunities and we believe
extends Emulex's addressable market for embedded storage components to more
than $800 million, and the Company's total available market to $2.7 billion by
2009," said Paul Folino, Chairman and CEO of Emulex. "Further, it builds upon
our prior acquisition of embedded switch supplier, Vixel, as well as our joint
development efforts with Intel. Together, Emulex and Sierra Logic will provide
our OEM customers with embedded solutions for the full range of enterprise
server and storage systems."

     Under the terms of the agreement, Emulex will acquire Sierra Logic for a
transaction value of up to approximately $180 million in cash, assumed debt and
assumed Sierra Logic stock options, plus employee equity incentive
compensation. The board of directors and shareholders of Sierra Logic have
approved the acquisition and it is expected to be complete on or near September
30, 2006, subject to certain closing conditions. Sierra Logic consists of
approximately 70 employees, primarily engineers based in Roseville, California.

     Emulex will incur charges associated with the acquisition of Sierra Logic,
including additional stock-based compensation, amortization of intangibles and
in-process research and development. However, as the valuation and the purchase
allocation have not been finalized for the previously announced Aarohi
acquisition, and pending the completion of the Sierra Logic acquisition, Emulex
is unable to predict the impact on its GAAP earnings per share for fiscal 2007
at this time. Given the expected timing of the closing of the acquisition, the
Non-GAAP impact is expected to be immaterial for the September quarter. For the
December quarter, the Sierra Logic acquisition is expected to contribute an
incremental $8-$10 million in revenues, and the Non-GAAP impact to diluted
earnings per share is expected to be neutral.

     "The solid customer base and product portfolio that Sierra Logic brings to
Emulex enables delivery of end-to-end embedded storage solutions that address
our OEM customers' tiered storage strategies," said Bob Whitson, CEO of Sierra
Logic. "Emulex's market-leading InSpeed embedded switch products and
multi-protocol IOCs, coupled with Sierra Logic's innovative embedded bridges
and routers, along with additional technology solutions currently under
development, bring unique synergies and benefits to our mutual customers."

     Sierra Logic's embedded bridges and routers enable integration of low-cost
SATA disk drives into enterprise storage systems, delivering cost-effective,
high-performance, and high-capacity storage innovations to the enterprise
market. With multiple design wins spanning a top-tier OEM customer base
including Engenio, Hitachi, Network Appliance, NEC, Sun Microsystems and
Xyratex, Sierra Logic products are in production today and recently achieved a
two-million SATA ports shipped milestone - further validating the rapid
adoption of SATA-based storage systems.

     Sierra Logic comes to Emulex with a strong management team that has deep
expertise in silicon development spanning end-to-end storage systems, and a
proven track record in providing component technology to market leading storage
OEMs. Additional details and financial information related to the acquisition
will be shared during a webcast conference call scheduled for today at 2pm
Pacific time. Visit the Emulex website at www.emulex.com for details.
