               12-March-1996


               Dear StorageWorks customer:


               We are announcing the availability of the StorageWorks
               HSZ40 Array Controller Utility for Digital UNIX V1.1A.
               The highlights of this utility are:

               o  A no-cost utility program allows Digital UNIX system
                  administrators to configure HSZ40 Array Controllers
                  using terminal windows on their Digital UNIX systems.
                  (NOTE: Digital UNIX systems were formerly known as
                  DEC OSF/1 systems.)

               o  It eliminates the need for a terminal to be directly
                  attached to the HSZ40 array controller.

               o  The full range of HSZ40 configuration and non-periodic
                  monitoring commands are available.

               The HSZ40 Array Controller supports a variety of in-
               dividual disk and disk array configuration options in
               the Digital UNIX environment. These include unit ad-
               dressing, read and write caching, array member removal
               and replacement, and others. Until now, configuring an
               HSZ40 Array Controller has required that a terminal be
               attached directly to the controller. This is not always
               convenient, particularly in large installations where
               the system administrator is not close to the system or
               storage he is configuring.

               The StorageWorks HSZ40 Array Configuration Utility for
               Digital UNIX allows communication with HSZ40 Array Con-
               trollers through a terminal window on a suitably privi-
               leged Digital UNIX workstation. The window behaves as if
               it were a terminal attached directly to the HSZ40. All
               controller CLI commands except those which make use of
               cursor positioning escape sequences are supported. For
               example, because this utility (called "HSZterm" in the
               HSZ40 Array Controller documentation) is character-cell
               oriented, it cannot handle the VTDPY displays (the peri-
               odic status displays emitted by the HSZ40) that include
               VTx00 escape sequences for cursor positioning.

               The StorageWorks HSZ40 Array Controller Utility works
               with all systems that support the Digital UNIX Oper-
               ating System V3.0, V3.2 or V4.0 and the HSZ40 Array
               Controller. HSZ40 Array Controllers must be running Op-
               erating Firmware (HSOF) Version 2.0 or later. In order
               to control stripesets or raidsets, licenses for those
               functions must be installed on the controller.
