Re:  Emulex Corporation (File No. 001-31353)
Form 10-K for the fiscal year ended July 3, 2005
Form 10-Q for the fiscal quarters ended October 2, 2005 and January 1, 2006

Dear Mr. Krikorian:

     On behalf of Emulex Corporation (the “Company” or “Emulex”), I am providing a supplemental response to your letter dated April 10, 2006 relating to the above-referenced annual and quarterly reports.

     As mentioned in a voice mail to Christopher White, Staff Accountant, by our outside counsel, the enclosed response restates our response to comment 3 contained in our April 25, 2006 letter in order to correct certain errors relating to the reclassification of amortization expense. In particular, in preparing the sample financial statements for our April 25, 2006 response, we inadvertently reclassified the amortization associated with patents acquired in a business combination from operating expenses to cost of goods sold, in addition to the core and developed technology intangible assets acquired. Our intention was to reclassify only the amortization of our core and developed technology assets acquired in business combinations in accordance with your recommendation. We apologize for the inconvenience this may have caused and enclose our revised response to comment 3 from your April 10, 2006 letter.

Form 10-K for Fiscal Year Ended July 3, 2005

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Fiscal 2005 versus Fiscal 2004

Consolidated Statement of Operations, page 54

3. Comment:

Your response to prior comment number 4 confirms that your products include intangible assets related to core technology which are being amortized in the income statement. Therefore, as your products sales include such technology, it appears that the appropriate line-item within continuing operations for this amortization should be cost of sales. In this regard, we note your reference to paragraph 42 of SFAS 142, and that this literature requires classification of amortization expense “as deemed appropriate for each entity.” This guidance does not support classifying the amortization expense simply based on an entity’s “policy election” without considering the nature of the charge. As your acquired technology is part of your cost of sales, it appears that based on the nature of this charge it should be classified in the cost of sales section. We further note your response references the guide of SAB Topic 11.B. Since you are presenting a gross profit line item in your statements of operations, in MD&A and in Note 16 — Quarterly Financial Data, the amortization charge must be included in cost of sales to properly present your gross profit. Revise or provide an analysis using SAB 99 that supports your conclusion not to amend prior Exchange Act Filings to properly present your gross profit.

Response:

In response to the Staff’s comments, the Company proposes to reclassify this amortization expense to cost of sales in future filings and to enhance our footnote disclosure. In order for the Staff to better understand the effect the reclassification will have on future filings, for your convenience, we have attached statements of operations which present the reclassified amounts compared to the previous presentation for the periods impacted by the reclassification. Those periods are the years ended June 27, 2004 and July 3, 2005, the three months ended January 1, 2006 and October 2, 2005, and the six months ended January 1, 2006. In future filings we will also reclassify statement of operations and related Disclosures in Management’s Discussion and Analysis to conform to the current presentation as necessary.

Additionally, the Company will amend its intangible assets footnote (currently footnote 7) in future filings to clarify where amortization expense of intangibles is classified in the statement of operations. The proposed changes to the footnote are presented in brackets and italics to assist in more clearly identifying them for purposes of this response.

“Goodwill related to the purchase of Vixel in 2004 and the purchase of Giganet in 2001. Core technology and patents relate to the purchase of Vixel and Giganet and to the purchase of the technology assets of Trebia Corporation for $2.1 million in October 2003. All other intangible assets subject to amortization relate to the purchase of Vixel. [The amortization expense associated with core technology and developed technology is included within the cost of sales line item in the Statement of Operations. The amortization expense associated with patents, customer relationships, tradename and covenants not-to-compete is included in the amortization of other intangibles line item which is within operating expenses.]”

“Aggregated amortization expense for these intangibles for the years 2006, 2005 and 2004, was $XX.X million, $26.2 million and $19.1 million, respectively, [of which $X.X million, $14.8 million and $11.5 million of amortization expense related to core technology and developed technology, respectively has been included in cost of sales within the Statement of Operations.]”

     Please do not hesitate to call me if you have any further comments or questions regarding this response.

Very truly yours,      Emulex Corporation
