Adaptec ASC-39320D-R KIT 2005200EU プリント

Overview
The Adaptec® SCSI Card 39320D is a
dual-channel 64-bit, 133 MHz  PCI-X SCSI
card that delivers fast, reliable performance
for enterprise servers and external storage
using Ultra320 SCSI technology. The
Adaptec SCSI Card 39320D powers your
server with data transfer rates of up to
320 MByte/sec per channel for mainline
storage, streaming video and audio, and
other bandwidth-intensive applications.

Adaptec SCSI Card 39320D           
The Need for Speed
The Adaptec SCSI Card 39320D card
incorporates packet protocol, the first
protocol change to SCSI in 20 years, and
Quick Arbitration and Selection (QAS).
Packetized SCSI optimises bus utilisation
and minimises command overhead to
bolster performance by transferring
commands, data, and status using Dual
Transition (DT) data phases instead of
slower asynchronous phases. Packet
protocol also allows multiple commands
to be transferred in a single connection.
QAS reduces the overhead of control
release on the SCSI bus from one device
to another to help decrease command
overhead and increase bus utilization.

Adaptec has extended its SCSI leadership
and reputation for innovation with Seamless
Streaming, a technology that optimizes
Ultra320 SCSI performance by ensuring
fast, smooth handling of data and command
packets. Seamless Streaming sends multiple
commands in a single connection, and
allows up to 512 commands to be rapidly
retrieved from its command management
queue. It also allows a SCSI target, such 
as a disk drive, to stream packets of data
for different commands with minimum
switching time, maximizing Ultra320
SCSI data transfer rates.

No Risk – No Compromises
The Adaptec SCSI Card 39320D is designed
for maximum configuration flexibility and
ease of use. Ultra320 SCSI technology is
compatible with Ultra160, Ultra2, Ultra Wide
and all other previous-generation SCSI
devices. The card’s PCI-X interface enables
host bus rates of over 1 GigaByte per second,
making it possible to take full advantage of
Ultra320 SCSI’s doubled bandwidth. It is
also backward compatible with PCI,
allowing you to retain legacy equipment.

Connect up to 30 SCSI Peripherals
Using two independent Ultra320 SCSI buses,
the Adaptec SCSI Card 39320D lets you
connect as many as 30 devices to your server,
including today’s most advanced Ultra320
SCSI hard drives. Its two 68-pin Ultra320
SCSI very high-density (VHDCI) external
connectors allow you to connect your  fastest
drives and arrays externally.

Enjoy the Highest Quality and
Broadest Compatibility
The Adaptec 39320D has been exhaustively
engineered and tested to deliver unsurpassed
reliability and compatibility. As the industry-
leading manufacturer of SCSI cards, Adaptec
assures the widest possible compatibility –
now and in the future.
