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

                  fifteenth  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

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, 2006, and the financial statements for the quarter ended September
30, 2006 required to be included therein (the "Form 10-Q") due to the additional
time  required to finalize a  calculation  relating  to the  liquidated  damages
required  to  be  paid  by  the  Company  to  certain  investors  pursuant  to a
Registration  Rights  Agreement,  dated and effective as of February 28, 2006 in
connection  with a private  placement  transaction  previously  disclosed in the
Company's  Current  Report on Form 8-K filed with the  Securities  and  Exchange
Commission  on August 4, 2006.  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

      notification.

      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
