                   EMC  CORPORATION  ANNOUNCES
              RECORD  AND  DISTRIBUTION  DATES  FOR
         DISTRIBUTION  OF  McDATA  CLASS A  COMMON STOCK

HOPKINTON, Mass. - January 12, 2001 - EMC Corporation (NYSE: EMC)
today announced that it has declared a stock dividend of all of
the shares of Class A common stock of McDATA Corporation (Nasdaq
National Market: MCDT) owned by EMC.  The dividend will be
distributed on February 7, 2001, to EMC stockholders of record as
of 5:00 p.m. Eastern time on January 24, 2001.  EMC currently
owns 81 million shares of McDATA Class A common stock, which
represents approximately 74 percent of the total outstanding
common stock of McDATA.

The Dividend Distribution
- -------------------------

     The McDATA Class A common stock will be distributed to EMC
stockholders in the amount of approximately 0.0369 of a share of
McDATA Class A common stock for each share of EMC common stock
(approximately 36 shares of McDATA Class A common stock for each
1,000 shares of EMC common stock).  The final ratio will be the
ratio of the number of shares of McDATA Class A common stock
owned by EMC to the actual number of shares of EMC common stock
outstanding on January 24, 2001, the record date.  As of December
31, 2000, the close of EMC's 2000 fiscal year, EMC had
approximately 2,195,000,000 shares outstanding.

     Ownership of the McDATA Class A common stock received by EMC
stockholders will be registered in book-entry form.  Each EMC
stockholder will receive a stock distribution statement from the
distribution agent. The statement will indicate the number of
full shares of McDATA Class A common stock that have been
credited to that EMC stockholder. Each EMC stockholder also will
receive a cash payment for any fractional shares of McDATA Class
A common stock.

     As previously announced, EMC has received a ruling from the
Internal Revenue Service that the distribution to EMC
stockholders of the McDATA Class A common stock will be tax free
to EMC stockholders for U.S. federal income tax purposes. Cash
received in lieu of fractional shares will be taxable.


     On August 9, 2000, McDATA completed the initial public
offering of its Class B common stock, which now is listed on the
Nasdaq National Market under the symbol "MCDT".

     McDATA was acquired by EMC in 1995 and was established as an
independent entity in 1997. In 1999 EMC introduced its Connectrix
family of SAN (storage area network) connectivity solutions,
designed and manufactured by McDATA.


Further Information on Distribution
- -----------------------------------

     After January 24, 2001, the record date, an information
statement will be mailed to EMC stockholders of record as of 5:00
p.m. Eastern time on the record date.  The information statement
will include the final ratio of shares of McDATA Class A common
stock to be distributed for each share of EMC common stock, as
well as information as to how to calculate the share cost basis
of such shares. McDATA has filed an application to list the Class
A common stock on the Nasdaq National Market under the symbol
"MCDTA."
