               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


Item 3.     Incorporation of Documents by Reference

            Storage Dimensions, Inc. (the "Company") hereby incorporates by
reference in this registration statement the following documents:

            (a)         The Registrant's Prospectus, filed on or about March 12,
                        1997 pursuant to Rule 424(b) promulgated under the
                        Securities Act of 1933, as amended (the "Securities
                        Act").

            (b)         The description of Registrant's Common Stock contained
                        in the Registrant's Registration Statement on Form 8-A
                        dated January 21, 1997, filed pursuant to Section 12(g)
                        of the Securities Exchange Act of 1934, as amended (the
                        "Exchange Act") which was declared effective on January
                        21, 1997 including any amendment or report filed for the
                        purpose of updating such description.

            All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment to this registration statement which indicates that all
securities offered hereby have been sold or which deregisters all securities
remaining unsold, shall be deemed to be incorporated by reference in this
registration statement and to be a part hereof from the date of filing of such
documents.

Item 4.     Description of Securities

            Not applicable.

Item 5.     Interests of Named Experts and Counsel

            Not applicable.

Item 6.     Indemnification of Directors and Officers

            Delaware law authorizes corporations to eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach or alleged breach of the directors' "duty of care." While the
relevant statute does not change directors' duty of care, it enables
corporations to limit available relief to equitable remedies such as injunction
or rescission. The statute has no effect on directors' duty of loyalty, acts or
omissions not in good faith or involving intentional misconduct or knowing
violations of law, illegal payment of dividends and approval of any transaction
from which a director derives an improper personal benefit. The Company has
adopted provisions in its Certificate of Incorporation which eliminate the
personal liability of its directors to the Company and its stockholders for
monetary damages for breach or alleged breach of their duty of care. The Bylaws
of the Company provide for indemnification of its directors, officers, employees
and agents to the full extent permitted by the General Corporation Law of the
State of Delaware, the Company's state of incorporation, including those
circumstances in which indemnification would otherwise be discretionary under
Delaware Law. Section 145 of the General Corporation Law of the State of
Delaware provides for indemnification in terms



                                      II-1
<PAGE>   4
sufficiently broad to indemnify such individuals, under certain circumstances,
for liabilities (including reimbursement of expense incurred) arising under the
Securities Act of 1933.

Item 7.     Exemption From Registration Claimed

                        Not applicable.

Item 8.     Exhibits

              4.1         1993 Stock Plan and Form of Agreement

              4.2         1996 Stock Plan*

Item 9.     Undertakings

            (a)         Rule 415 Offering   The undersigned registrant hereby 
undertakes:

                        (1) To file, during any period in which offers or sales
are being made, a post-effective amendment to this registration statement:

                              (i) To include any prospectus required by section
10(a)(3) of the Securities Act of 1933;

                              (ii) To reflect in the prospectus any facts or
events arising after the effective date of the registration statement (or the
most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
registration statement;

                              (iii) To include any material information with
respect to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in the registration
statement;

            Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
apply if the registration statement is on Form S-3 (Section 239.13 of this
chapter) or Form S-8 (Section 239.16(b) of this chapter), and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the



                                      II-2
<PAGE>   5
registrant pursuant to section 13 or section 15(d) of the Exchange Act that are
incorporated by reference in the registration statement.

                        (2) That, for the purpose of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                        (3) To remove from registration by means of a
post-effective amendment any of the securities being registered which remain
unsold at the termination of the offering.

            (b)         Filing incorporating subsequent Exchange Act documents 
by reference

                        The undersigned registrant hereby undertakes that, for 
purposes of determining any liability under the Securities Act of 1933, each
filing of the registrant's annual report pursuant to section 13(a) or section
15(d) of the Exchange Act (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to section 15(d) of the Exchange Act) that
is incorporated by reference in the registration statement shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            (h)         Request for acceleration of effective date or filing of 
registration statement on Form S-8

                        Insofar as indemnification for liabilities arising under
the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the registrant pursuant to the foregoing provisions, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Milpitas, State of California, on June 6, 1997.

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3.     Incorporation of Documents by Reference

            Storage Dimensions, Inc. (the "Company") hereby incorporates by
reference in this registration statement the following documents:

            (a)         The Registrant's Prospectus, filed on or about March 12,
                        1997 pursuant to Rule 424(b) promulgated under the
                        Securities Act of 1933, as amended (the "Securities
                        Act").

            (b)         The description of Registrant's Common Stock contained
                        in the Registrant's Registration Statement on Form 8-A
                        dated January 21, 1997, filed pursuant to Section 12(g)
                        of the Securities Exchange Act of 1934, as amended (the
                        "Exchange Act") which was declared effective on January
                        21, 1997 including any amendment or report filed for the
                        purpose of updating such description.

            All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment to this registration statement which indicates that all
securities offered hereby have been sold or which deregisters all securities
remaining unsold, shall be deemed to be incorporated by reference in this
registration statement and to be a part hereof from the date of filing of such
documents.

Item 4.     Description of Securities

            Not applicable.

Item 5.     Interests of Named Experts and Counsel

            Not applicable.

Item 6.     Indemnification of Directors and Officers

            Delaware law authorizes corporations to eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach or alleged breach of the directors' "duty of care." While the
relevant statute does not change directors' duty of care, it enables
corporations to limit available relief to equitable remedies such as injunction
or rescission. The statute has no effect on directors' duty of loyalty, acts or
omissions not in good faith or involving intentional misconduct or knowing
violations of law, illegal payment of dividends and approval of any transaction
from which a director derives an improper personal benefit. The Company has
adopted provisions in its Certificate of Incorporation which eliminate the
personal liability of its directors to the Company and its stockholders for
monetary damages for breach or alleged breach of their duty of care. The Bylaws
of the Company provide for indemnification of its directors, officers, employees
and agents to the full extent permitted by the General Corporation Law of the
State of Delaware, the Company's state of incorporation, including those
circumstances in which indemnification would otherwise be discretionary under
Delaware Law. Section 145 of the General Corporation Law of the State of
Delaware provides for indemnification in terms

                                      II-1

sufficiently broad to indemnify such individuals, under certain circumstances,
for liabilities (including reimbursement of expense incurred) arising under the
Securities Act of 1933.

Item 7.     Exemption From Registration Claimed

                        Not applicable.

Item 8.     Exhibits

              4.1         1993 Stock Plan and Form of Agreement

Item 9.     Undertakings

            (a)         Rule 415 Offering   The undersigned registrant hereby 
undertakes:

                        (1) To file, during any period in which offers or sales
are being made, a post-effective amendment to this registration statement:

                              (i) To include any prospectus required by section
10(a)(3) of the Securities Act of 1933;

                              (ii) To reflect in the prospectus any facts or
events arising after the effective date of the registration statement (or the
most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
registration statement;

                              (iii) To include any material information with
respect to the plan of distribution not previously disclosed in the registration
statement or any material change to such information in the registration
statement;

            Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
apply if the registration statement is on Form S-3 (Section 239.13 of this
chapter) or Form S-8 (Section 239.16(b) of this chapter), and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the

                                      II-2
5
registrant pursuant to section 13 or section 15(d) of the Exchange Act that are
incorporated by reference in the registration statement.

                        (2) That, for the purpose of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                        (3) To remove from registration by means of a
post-effective amendment any of the securities being registered which remain
unsold at the termination of the offering.

            (b)         Filing incorporating subsequent Exchange Act documents 
by reference

                        The undersigned registrant hereby undertakes that, for 
purposes of determining any liability under the Securities Act of 1933, each
filing of the registrant's annual report pursuant to section 13(a) or section
15(d) of the Exchange Act (and, where applicable, each filing of an employee
benefit plan's annual report pursuant to section 15(d) of the Exchange Act) that
is incorporated by reference in the registration statement shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

            (h)         Request for acceleration of effective date or filing of 
registration statement on Form S-8

                        Insofar as indemnification for liabilities arising under
the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the registrant pursuant to the foregoing provisions, or
otherwise, the registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-8 and has duly caused this registration
statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Milpitas, State of California, on June 6, 1997.
