CS5-HORN
CompactPCI Dual Ultra160 SCSI Hostadapter
2 x 160MBps, up to 30 SCSI Peripheral Devices
The CS5-HORN from EKF is a
CompactPCI®
based Dual Ultra160 SCSI hostadapter,
suitable for attachment of LVD/SE 16-bit
peripherals as Raid-systems, high
performance hard disks and streamer tape
drives. Provided with two independent
ports, both channels can be dedicated to
LVD devices, or alternatively one channel
can be used to support mixed performance
SE devices.
The CS5-HORN provides up to 320MBps
aggregate SCSI throughput. Optimum
performance therefore is achieved when
the HORN is operated in a 64-bit CPCI
backplane, but 32-bit legacy systems also
profit from the power of this SCSI controller.

|
By double transition clocking, Ultra160
speeds up the data transfer rate of Ultra2
from 80MBps to 160MBps per channel.
Other Ultra160 features are Domain
Validation and Cyclic Redundancy Check.
Compatibility is maintained to all previous
SCSI standards, e.g. Fast, Ultra and Ultra2
SCSI. The CS5-HORN is provided with two
external VHDCI receptacles and one internal
HDSUB connector; so external and internal
devices can be connected simultaneously.
Comprehensive software support as well as
PCI plug&play technology care for effortless
installation of the CS5-HORN under nearly all
popular operating systems.
|
The CS5-HORN provides a Flash Extended
BIOS, thus enabling operating system boot
from any SCSI drive. The Flash-EEPROM can
be field upgraded at any time by means of a
utility program. The CS5-HORN is additionally
equipped with two serial EEPROMs, saving
configuration parameters of each of the
two SCSI channels (e.g. for SCAM support).
In order to ease system integration, several
LEDs show important board status
information:
|
|
The CS5-HORN sources the voltages for the
on-board and external SCSI terminators
(TERMPOWER), fused by Polyswitches
(reversible fuse).
SCSI Bus data and control signal integrity
will be improved by the SCSI controller chip
using the Symbios Tolerant™ filtering
technology, thus minimizing the influence
of a critical SCSI cabling (poor cables, mixed
cable types, noisy environment).

The CS5-HORN is provided with a 64-bit
CPCI interface, giving a nominal bandwidth
of 532MBps @66MHz in a suitable system
(P1/P2 backplane). This is by far enough to
handle the theoretical aggregate maximum
320MBps SCSI data stream. However, a 64-bit @33MHz CPCI System
(266MBps) seems
to be slightly imbalanced.
Actually, the SCSI buses operate with
considerable lower data transfer rates.
Usual configurations dedicate one of the
SCSI channels to mixed performance SE
devices, while the other channel is reserved
for the LVD devices only (this is done
because an SE peripheral on a SCSI bus
forces all LVD devices into the legacy single
ended mode). The SE organized SCSI bus
however operates with a maximum of
40MBps (20MBps if 8-bit narrow devices).
Furthermore, most peripherals by far do not
reach the maximum data transfer rates
when accessed outside their local caches
due to latency periods. Therefore, the CS5-HORN is an
outstanding choice also for 32-bit
CPCI systems with a nominal bandwidth of
133MBps.
|
|
SureLINK™ domain validation technology
detects the configuration of the SCSI buses
and automatically tests and adjusts the SCSI
transfer rate to optimize interoperability.
The CS5-HORN exceeds Ultra160 by
providing not only Basic (Level 1) and
Enhanced (Level 2) domain validation, but
adds Margined (Level 3) domain validation.
This enhancement margins LVD drive
strength and clock signal timing
characteristics to identify marginal Ultra3
systems.

CS5-HORN - Component Assembly

CRC improves the reliability of SCSI data
transmission through enhanced detection
of communication errors. The CRC has a rate of
aproximately 2-32 of undetected error
patterns. CRC is the best way to ensure data
protection during hot plugging.
To provide complete end-to-end protection
of the SCSI I/O, AIP (Asynchonous
Information Protection) protects all non-data-phases
(command, status, message),
augmenting the CRC feature of Ultra160.
A toolset already mentioned, but worth to
be more intensively discussed is the Symbios
SCSI Device Management Software SDMS,
running on the CS5-HORN without any
modification. SDMS is a package of utilities
and drivers, including ASPI, RAID, or
removeable media support for popular disk
operating systems. As a resident part of the
SDMS, basic routines are contained within
the on-board Flash Extended BIOS. Like any
other BIOS routine, this resident software
does not depend on an individual OS, but
allows standalone operation and
diagnostics instead, e.g. low level harddisk
formatting or SCSI bus configuration.

The CS5-HORN is a 3U (single size) Eurocard.
For 6U
CompactPCI®
systems there is a
mechanical kit available, expanding the
front panel to 6U (CR9-ADAPT).
It is not necessary to discuss the advantages of
SCSI here, such as superior data throughput at
minimal CPU load. With the CS5-HORN, any
CompactPCI®
system can profit from dual Ultra160
SCSI performance. The CS5-HORN is an
affordable, highly reliable industrial grade
product, and - last not least - fast and
smoothly to be installed.

Whenever both external SCSI channels are in use (front panel mounted dual VHDCI
receptacle), the connector style of the external VHDCI cabling set is important.
Connectors conforming to the VHDCI standard are provided with an asymmetric
cable entrance with respect to the center of the pin rows. However, there are
cable assemblies available with symmetric VHDCI connectors, resulting in the
effect that the plug partly overlaps the neighbouring VHDCI receptacle.
Furthermore, cables must comply with Ultra160 LVD/SE standards.
