Section 1
Overview
The PetaSite DMS-B150L/B210S/B80L/B110S/EX150L/EX210S controls the many cassette tapes that
are used in the DTF digital tape streamer so that huge volumes of data can be stored, searched, recorded
and played back. It is used as the key equipment.
The PetaApp system realizes the large capacity data processing and backup at a high speed. The required
software and hardware are integrated in the single system that enables to construct a highly reliable
backup system. (In this document, the PetaSite 150/80 series that is set in the PetaApp system is called
the Package-supporting model. At the same time, the other equipment than the PetaSite 150/80 series that
is used in the PetaApp system is called the Package-supporting equipment.)
PetaSite 150/80 series of products consists of two models : the model for L cassettes which focus on large
capacity, and the model for S cassettes which offer superior performance in terms of high-speed access.
The optimum system can be built to suit the application, such as using the model for L cassettes when the
system needs a large capacity for data backup, or the model for S cassettes when the system needs high-
speed access such as for HSM or archiving.
Thanks to the high-speed access mechanism, the cassette transfer time of five seconds with 360 cassette
changes per hour (estimated averages) and accesses per hour of about two to six times faster than that of
the conventional model are realized. As a result, convenient data access is possible; the average data
access start time is thirty seconds or shorter when S cassettes are used, and one minute or shorter when L
cassettes are used. (Both times are the average when DTF-2 is mounted.)
DMS-B80L/B110S (PetaSite80 series)
The PetaSite80 series can store up to 16.2 terabytes of data in the compact body (when L cassettes are
used and DTF-2 is mounted). In addition, up to four tape drives can be mounted.
DMS-B150L/B210S/EX150L/EX210S (PetaSite150 series)
The PetaSite150 series consists of the DMS-B150L/B210S basic console and DMS-EX150L/EX210S
extension consoles. Up to one or two extension consoles can be connected to the basic console, when the
extension belt kit DMSA-BLT2 is used.
When the extension belt kit DMSA-BLT6 and the extension cable kit DMSA-CBL1 are used, the exten-
sion consoles can be connected in the range of 3 to 6. When the extension consoles in the range of 3 to 6
are connected, the cassette transport time becomes 7 second (average) and the number of cassette change
becomes 300 cassettes (average) per hour.
In addition, the BetaCam series
*
of professional video cassette recorders that are used in worldwide broad-
cast stations and production companies can be mounted in the extension console, and various applications
such as picture archiving can be supported by using cassette tapes together with the DTF streamer.
*
: BetaCam series is the VTR of 5U having SDI output function
DMSA-TS08/DMSA-TS16/DMSA-TS08K TERMINAL SERVER
This is the terminal server that can perform the RS-232C communication by integrating them into the
TCP/IP communication.
DMSA-EH16 ETHERNET HUB
This is the Ethernet switching hub.
DMSA-AT80 ATTACHMENT KIT
This is the attachment kit to install the DMS-PCU1 and the DMS-FSW24/FSW28 into the DMS-B80L.
DMSA-SBE1 SCSI BUS EXPANDER KIT
This kit enables to separate the SCSI equipment (between the SCSI tape streamer and host computer)
with the disable switch by electrically. Therefore, removal of the SCSI equipment from the SCSI bus
becomes easy in the event of maintenance, etc.
DMSA-CBJ80/CBJ15/CBJEX AC POWER CABLE KIT
This is the kit to connect the power cablings inside the PetaSite80/150 series.
