03-19665. Issuer Delisting; Notice of Application To Withdraw From Listing and Registration on the American Stock Exchange LLC (Dot Hill Systems Corp., Common Stock, $.001 par value); File No. 1-13317

July 29, 2003.

Dot Hill Systems Corp., a Delaware corporation (“Issuer”), has filed an application with the Securities and Exchange Commission (“Commission”), pursuant to Section 12(d) of the Securities Exchange Act of 1934 (“Act”) ^[1] and Rule 12d2-2(d) thereunder,^[2] to withdraw its Common Stock, $.001 par value (“Security”), from listing and registration on the American Stock Exchange LLC (“Amex” or “Exchange”).

The Issuer stated in its application that it has met the requirements of Amex Rule l8 by complying with all applicable laws in the State of Delaware, in which it is incorporated, and with the Amex's rules governing an issuer's voluntary withdrawal of a security from listing and registration.

The Issuer stated that it is taking such action because the Issuer believes that listing on the Nasdaq National Market will provide superior trading and visibility in the investment community, among other advantages. The Issuer also stated that this is of particular importance as the Issuer anticipates pursuing a follow-on public offering in the near future.

The Issuer's application relates solely to the withdrawal of the Securities from listing on the Amex and from registration under Section 12(b) of the Act ^[3] shall not affect its obligation to be registered under Section 12(g) of the Act. ^[4]

Any interested person may, on or before August 18, 2003, submit by letter to the Secretary of the Securities and Exchange Commission, 450 Fifth Street, NW., Washington, DC 20549-0609, facts bearing upon whether the application has been made in accordance with the rules of the Amex and what terms, if any, should be imposed by the Commission for the protection of investors. The Commission, based on the information submitted to it, will issue an order granting the application after the date mentioned above, unless the Commission determines to order a hearing on the matter.

For the Commission, by the Division of Market Regulation, pursuant to delegated authority.^[5]

Jonathan G. Katz,

Secretary.
