Overview
The KZPSA adapter is a
Peripheral Component Interconnect (PCI) to Small Computer System
Interface-2 (SCSI-2) adapter. You install the adapter on your
computer motherboard through a PCI connector for 32 bit/+5V
operation. Each adapter provides connection for one fast, wide
differential SCSI bus. Cabling provides the interconnect between the
adapter and a storage device. The adapter supports up to 15 devices,
including RAID controllers. Both 8-bit differential SCSI bus devices
and 16-bit differential SCSI bus devices can be directly connected.
To connect single-ended devices, you must use a
differential-to-single-ended SCSI bus converter, such as a Digital
DWZZA bus converter.
The adapter's processor
minimizes the SCSI I/O overhead of the host computer's processor by
interpreting host commands and translating them into specific device
commands. This includes support for direct data transfer to host
memory, coding device-specific commands into specific command
scripts, and supporting internal command queues with
disconnect/reconnect functionality. The KZPSA is capable of 32-bit
bus master data transfers, including PCI enhanced data transfer
commands. The host adapter supports most SCSI-2 functions. The host
adapter supports multithreaded IO operations, thereby allowing
simulta- neous operations on multiple SCSI targets or Logical Units
(LUNs). In systems with multiple targets, the Disconnect / Reconnect
feature optimizes SCSI bus usage. In systems that have fragmented
memory buffers, the Scatter/Gather feature provides high
performance. In addition to its normal role of SCSI initiator, the
KZPSA provides support for target mode operations. In this mode, the
KZPSA can receive incoming SCSI-2 processor commands intended for
its locally connected host. This functionality makes the KZPSA, with
operating system support, an integral component in advanced system
configurations such as the high availability DECsafe Available
Server Environment.
The KZPSA has several
parameters the user can change to optimize the adapter's
functionality within the system. These parameters may be changed
using the configuration utility software included with the module.
This utility provides the compability of changing settings on the
boards NVRAM without having to make physical changes to the host
adapter board.

Description
The SWXCR family of products includes both EISA and PCI based controllers.
The KZPSC is the PCI based version of the product. These products
provide hardware based RAID capabilities for nonstop access to
critical data. RAID levels 0 (striping), 1 (mirroring), 0+1 (striped
shadowing), and 5 (striping with parity) are provided by these
controller to protect data. Hot swapping of disks, automatic reconstruct,
and spare disks are all supported to further protect your data.
