     Reference is made to the comment letter received from the Securities and Exchange Commission (the “Commission”) dated February 7, 2007 by Network Appliance, Inc.

However, in light of our call with you yesterday, the Company will require additional time in order to revise its response to reflect our discussion with you yesterday. Therefore, the Company respectfully requests that it be granted an extension until April 6, 2007 to provide a response to the comment letter. Please contact the undersigned if you wish to discuss our request for an extension.

Sincerely,
