Item 1. Security and Issuer.

This statement relates to the ordinary shares, nominal value NIS 0.01 (the “Ordinary Shares”), issued by Voltaire Ltd., a company formed under the laws of Israel (“Voltaire”). The address of the principal executive offices of Voltaire is 13 Zarchin Street, Ra’anana 43662, Israel.

Item 2. Identity and Background.

(a) This statement is being filed pursuant to Rule 13d-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), by Mellanox Technologies, Ltd., a public company formed under the laws of Israel (“Mellanox”).

(b) The address of the principal business and the principal office of Mellanox is Hermon Building, Yokneam 20692, Israel.

(c) Mellanox is a leading supplier of semiconductor-based, high-performance connectivity products that facilitate efficient data transmission between servers, communications infrastructure equipment and storage systems. The name, business address, present principal occupation or employment and citizenship of each director and executive officer of Mellanox is set forth on Schedule I.

(d) — (e) During the last five years, none of Mellanox or, to the knowledge of Mellanox, any of the persons listed on Schedule I has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

The total cash purchase price for Mellanox’s acquisition of Voltaire pursuant to the Merger Agreement (as defined in Item 4) is approximately $208 million (approximately $175 million net of cash). Mellanox also assumed Voltaire’s outstanding equity awards, which were converted into equity awards to acquire an aggregate of 649,614 ordinary shares of Mellanox. Mellanox obtained funding for the acquisition from its existing working capital.

Item 4. Purpose of Transaction.

On November 29, 2010, Mellanox entered into an Agreement of Merger (the “Merger Agreement”) with Voltaire and Mondial Acquisition Corporation Ltd., a company formed under the laws of Israel and a wholly owned subsidiary of Mellanox (“Merger Sub”). In accordance with the Merger Agreement, Merger Sub merged with and into Voltaire (the “Merger”) on February 7, 2011. Voltaire was the surviving corporation in the Merger, and, as a result of the Merger, has become a wholly owned subsidiary of Mellanox. As a result of the Merger, the Ordinary Shares ceased to be traded on The NASDAQ Global Select Market and the registration of the Ordinary Shares under the Exchange Act was terminated. At the effective time of the Merger (the “Effective Time”), all outstanding ordinary shares of Voltaire were exchanged for the right to receive a cash amount equal to US$8.75, without interest. The total cash purchase price is approximately $208 million (approximately $175 million net of cash). Mellanox also assumed Voltaire’s outstanding equity awards, which were converted into equity awards to acquire an aggregate of 649,614 ordinary shares of Mellanox. In connection with the Merger, the directors and executive officers of Voltaire resigned, and Eyal Waldman, Irwin Federman and Amal Johnson became the directors of Voltaire. The summary of certain provisions of the Merger Agreement in this Schedule 13D/A is qualified in its entirety by reference to the Merger Agreement itself, a copy of which was filed as Exhibit 2.1 to Mellanox’s Current Report on Form 8-K dated November 29, 2010 and is incorporated herein by reference.

Other than as described in this Schedule 13D/A, Mellanox currently has no plans or proposals which relate to, or may result in, any of the matters listed in Items 4(a)-(j) of the General Instructions to Schedule 13D.

Item 5. Interest in Securities of the Issuer.

(a)—(b) As a result of the Merger, Mellanox beneficially owns 22,070,997 Ordinary Shares as of the Effective Time, representing 100% of the issued and outstanding Ordinary Shares.

Mellanox has the power to vote or direct the voting and to dispose or direct the disposition of all Ordinary Shares beneficially owned.

(d) To the knowledge of Mellanox, no other person has the right to receive or the power to direct the receipt of dividends from, or proceeds from the sale of, the Ordinary Shares.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Except as set forth in Item 4, neither Mellanox nor, to the best knowledge of Mellanox, any person set forth on Schedule I hereto, has any contracts, arrangements, understandings or relationships (legal or otherwise) with any other person with respect to any securities of Voltaire or its subsidiaries.

Item 7. Material to be Filed as Exhibits.

Agreement of Merger, dated as of November 29, 2010, by and among Mellanox Technologies, Ltd., Mondial Acquisition Corporation Ltd. and Voltaire Ltd. (incorporated by reference to Exhibit 2.1 to the Current Report on Form 8-K filed by Mellanox Technologies, Ltd. on November 29, 2010).
