PART I -- REGISTRANT INFORMATION

SAN Holdings, Inc.
- ------------------
(Full Name of Registrant)


- ------------------------------------
(Former Name if Applicable)

9800 Pyramid Court, Suite 130
- ------------------------------------
(Address of Principal Executive Office (Street and Number))

Englewood, CO 80112
- ------------------------------------

PART II -- RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25(b), the following should
be completed. (Check box if appropriate)

        |  (a)    The reasons described in reasonable detail in Part III of
        |         this form could not be eliminated without unreasonable effort
        |         or expense;
        |  (b)    The subject annual report, semi-annual report, transition
        |         report on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form
        |         N-CSR or portion thereof will be filed on or before the
        |         fifteenth
  [X]   |         calendar day following the prescribed due date; or the
        |         subject quarterly report or transition report on Form 10-Q,
        |         or portion thereof will be filed on or before the fifth
        |         calendar day following the prescribed due date; and
        |  (c)    The accountant's statement or other exhibit required by Rule
        |         12b-25(c) has been attached if applicable.

PART III -- NARRATIVE

         State below in reasonable detail the reasons why Forms 10-K, 20-F,
11-K, 10-Q, N-SAR or N-CSR, or the transition report or portion thereof, could
not be filed within the prescribed time period.

         SAN Holdings, Inc. (the "Company") has determined that additional time
is required to finalize its Quarterly Report on Form 10-Q for the quarter ended
September 30, 2007, and the financial statements for the quarter ended September
30, 2007, required to be included therein (the "Form 10-Q") due to the
additional time required to finalize matters and disclosure relating to the
Company's liquidity position. These matters continue to take a substantial
amount of time to resolve, and executive management and available personnel that
are responsible for the liquidity issues, have been unable to do so in
sufficient time to file the Form 10-Q within the prescribed period. Despite
diligent efforts by the Company, the Company is not able, without unreasonable
effort or expense, to file the Form 10-Q within the prescribed period. The
Company expects to file the Form 10-Q within the five-day extension period.

PART IV -- OTHER INFORMATION

(1)      Name and telephone number of person to contact in regard to this
         notification.

                    (Name)                      (Area Code) (Telephone Number)

(2)      Have all other periodic reports required under Section 13 or 15(d) of
         the Securities Exchange Act of 1934 or Section 30 of the Investment
         Company Act of 1940 during the preceding 12 months or for such shorter
         period that the registrant was required to file such report(s) been
         filed? If answer is no, identify report(s).
                                                                  [X] Yes [ ] No

(3)      Is it anticipated that any significant change in results of operations
         from the corresponding period for the last fiscal year will be
         reflected by the earnings statements to be included in the subject
         report or portion thereof?
                                                                  [ ] Yes [X] No

         If so, attach an explanation of the anticipated change, both
         narratively and quantitatively, and, if appropriate, state the reasons
         why a reasonable estimate of the results cannot be made. Explanation of
