This Amendment No. 4 hereby amends the Statement on Schedule 13D (the “Schedule 13D”) previously filed on April 4, 2003, as amended by Amendment No. 1 previously filed on April 13, 2004, Amendment No. 2 previously filed on March 28, 2005 and Amendment No. 3 previously filed on May 17, 2005 by Sun Solunet, LLC, a Delaware limited liability company (“Sun Solunet”), Sun Capital Partners II, LP, a Delaware limited partnership (“Sun Partners II LP”), Sun Capital Advisors II, LP, a Delaware limited partnership (“Sun Advisors II”), Sun Capital Partners, LLC, a Delaware limited liability company (“Sun Partners LLC”), Marc J. Leder (“Leder”) and Rodger R. Krouse (“Krouse”) (collectively, the “Reporting Persons”) with respect to the common stock of SAN Holdings, Inc. (the “Issuer”) as follows:

	Item 3.	Source and Amount of Funds or Other Consideration
	Item 3 is amended and supplemented by adding the following:
On June 3, 2005, the Issuer increased the borrowing availability from $10 million to $11.5 million under the revolving credit facility (the “Harris Facility”) that the Issuer maintains with Harris Trust and Savings Bank (“Harris Trust”). As a condition precedent to the amendment of the Harris Facility, on June 3, 2005, Sun Solunet increased the amount of the ongoing guaranty of the debt incurred by the Issuer under the Harris Facility. On June 27, 2005, in partial consideration for Sun Solunet increasing its ongoing guaranty, the Issuer authorized the issuance of a stock purchase warrant to Sun Solunet for 480,969 shares of common stock of the Issuer, at an exercise price of $0.001 per share. The Issuer and Sun Solunet agreed that the number of shares to be issued would be calculated based on the same formula used in the Credit Support Agreement.
On June 29, 2005, the Issuer issued to Sun Solunet such stock purchase warrant (the “June 2005 Supplemental Warrant”). The preceding summary of terms of the June 2005 Supplemental Warrant is qualified in its entirety by reference to the detailed provisions of the June 2005 Supplemental Warrant, a copy of which is attached hereto as Exhibit L and incorporated herein by reference.
The shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the June 2005 Supplemental Warrant constitute approximately 0.4% of the Issuer’s outstanding common stock.

	Item 4.	Purpose of Transaction
	Item 4 is amended and supplemented by adding the following:
Pursuant to the terms of the June 2005 Guaranty Warrant (as defined in Item 3 above), Sun Solunet may purchase, at a price per share of $0.001, an aggregate of 480,969 shares of common stock of the Issuer.
On May 12, 2005, the board of directors (the “Board”) of the Issuer appointed T. Scott King as a director of the Company to fill the vacancy created by the resignation of Benjamin Emmons on March 25, 2005. The Company’s bylaws provide that each director is to hold office until the next annual meeting of shareholders and until his successor is elected and qualified or until such director’s earlier death, resignation or removal. The other members of the Issuer’s Board are John Jenkins, Marc J. Leder, Rodger R. Krouse, Clarence E. Terry, M. Steven Liff, Stephen G. Marble, Gary F. Holloway, C. Daryl Hollis, and George R. Rea.

	Item 5.	Interest in Securities of the Issuer
	Item 5 is amended and restated in its entirety as follows:
	(a)	As of the date hereof, the Reporting Persons may be deemed to be the beneficial owner, within the meaning of Rule 13d-3 of the Exchange Act, of 70,930,907 shares of Common Stock, or approximately 64.9% of the Common Stock outstanding. This number is comprised of (a) 55,968,562 shares of Common Stock that are held directly by Sun Solunet, (b) 7,715,545 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the March 2005 Guaranty Warrant, (c) 3,086,218 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the March 2005 Supplemental Warrant, (d) 2,244,522 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the May 2005 Guaranty Warrant, (e) 480,969 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the June 2005 Supplemental Warrant and (f) 1,435,091 shares of Common Stock that are held directly by the Phelans.
	(b)	Each Reporting Person may be deemed to have shared power to vote or direct the vote of 70,930,907 shares of Common Stock, or approximately 64.9% of the Common Stock outstanding. This number is comprised of (a) 55,968,562 shares of Common Stock that are held directly by Sun Solunet, (b) 7,715,545 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the March 2005 Guaranty Warrant, (c) 3,086,218 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the March 2005 Supplemental Warrant, (d) 2,244,522 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the May 2005 Guaranty Warrant, (e) 480,969 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the June 2005 Supplemental Warrant and (f) 1,435,091 shares of Common Stock that are held directly by the Phelans.

This number is comprised of (a) 55,968,562 shares of Common Stock that are held directly by Sun Solunet, (b) 7,715,545 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the March 2005 Guaranty Warrant, (c) 3,086,218 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the March 2005 Supplemental Warrant, (d) 2,244,522 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the May 2005 Guaranty Warrant and (e) 480,969 shares of Common Stock that are issuable, currently or within 60 days of this report, to Sun Solunet pursuant to the terms of the June 2005 Supplemental Warrant.
		The Reporting Persons and the Phelans may be deemed to constitute a “group” for purposes of Section 13(d)(3) of the Exchange Act as a result of the transfer provisions contained in the Shareholders Agreement and the registration provisions contained in the Registration Agreement. The Reporting Persons expressly disclaim that they have agreed to act as a group with the Phelans. The table below lists the number of shares

	beneficially owned by the Phelans in which the Reporting Persons may be deemed to have beneficial ownership because of the Shareholders Agreement and the Registration Agreement.
