B-14 Sun MediaCenter Server Administrator’s Guide • December 1997
The recommended block size of the tar format is 500 512-byte blocks, or 256,000
bytes. The default blocking factor for tar is 20 blocks, or 10,240 bytes.
B.6.2 Tapes
The Sun MediaCenter server supports both 4-mm and 8-mm cartridge tapes.
B.7 Example
This section provides an example of a content package—the TOC file and the index
and data files for each bit stream—and its storage on a tape using the tar format.
The names of the files that make up our example content package are shown in the
tar output, below:
The tar tf command above lists the table of contents on a tar file or device,
/dev/rmt/0 in this example. The tar output indicates that the content package
consists of a TOC file, bambi.TOC, and five bit streams associated with the content
at various speeds. Each bit stream contains an index file (.index) and an MPEG
data file (.mpeg).
In our example, as in
FIGURE B-2 on page B-13, the index files for a content package
appear immediately after the TOC file on the tape.
