           VAX Storage Library System, Version 2.1   SSA 29.67.04-A


           o  One RD-series or RA-series disk

           Disk Space Requirements (Block Cluster Size = 1):

           VAX SLS and VAX SLS REMOTE software can be run on any valid
           VAX, MicroVAX, VAXstation, or VAXserver configuration with
           DECnet support.

           Disk Space Required for VAX SLS Software:

           VAX SLS node:

           Disk space required for     4,100 blocks
           installation:
                                       (2.1 Mbytes)

           Disk space required for     3,500 blocks
           use (permanent):
                                       (1.8 Mbytes)

           VAX SLS REMOTE node:

           Disk space required for     3,800 blocks
           installation:
                                       (1.95 Mbytes)

           Disk space required for     2,900 blocks
           use (permanent):
                                       (1.5 Mbytes)

           Disk Space Required By the VAX SLS Media Database and His-
           tory Files:

           The VAX SLS media database is present only on nodes execut-
           ing VAX SLS software (i.e., not on nodes executing VAX SLS
           REMOTE software). The disk space required by the VAX SLS me-
           dia database depends on the number of pieces of media to be
           managed. During installation, the storage administrator may
           designate the disk on which the VAX SLS media database is

           VAX Storage Library System, Version 2.1   SSA 29.67.04-A


           to be kept. For enhanced data safety, the VAX SLS media database
           may be stored on a shadowed disk.

           VAX SLS history files are present on any node executing ei-
           ther VAX SLS software or VAX SLS REMOTE software. The disk
           space required by a VAX SLS history file depends on the num-
           ber of files to be tracked by VAX SLS software. During in-
           stallation, the storage administrator may designate the disk
           on which the VAX SLS history file is to be kept. For enhanced
           data safety, the VAX SLS history file may be stored on a shad-
           owed disk.

           Total Disk Space Requirements for VAX SLS Software:

           Execution of VAX SLS software requires 3,500 blocks (the num-
           ber of blocks occupied by VAX SLS software itself) plus one
           block for every piece of media it manages plus one block for
           every six files it tracks.

           Example: Assume there are 1,500 pieces of media under man-
           agement by VAX SLS software and 60,000 files are tracked.
           The disk space required is:

           VAX SLS software:           3,500 blocks
           Media database:             1,500 blocks
           History files:              10,000 blocks
           TOTAL                       15,000 blocks
                                       (7.7 Mbytes)

           Total Disk Space Requirements for VAX SLS REMOTE Software:

           Execution of VAX SLS REMOTE software requires 2,900 blocks
           (the number of blocks occupied by VAX SLS REMOTE software
           itself) plus one block for every six files it tracks.

           Example: Assume there are 60,000 files known to VAX SLS RE-
           MOTE software. The disk space required is:

           VAX Storage Library System, Version 2.1   SSA 29.67.04-A



           VAX SLS REMOTE software:    2,900 blocks
           History files:              10,000 blocks
           TOTAL                       12,900 blocks
                                       (6.6 Mbytes)

           In addition to the disk space specified above, adequate disk
           storage must be available on the host system to accommodate
           history files if that option is selected.

           The space requirements specified herein are approximate; ac-
           tual space requirements may vary depending on system envi-
           ronment, configuration, and software options selected.
