Chapter 1. About SCSIDE II
The Overview
ACARD is an expert of storage. It has years of experiences in the design,
development and application of storage devices. The quick solutions it provides
always meet the market demand, and have won praise from some well-known
manufacturers in the world. Over the years its exclusive SCSIDE technology, chips
and system applications have obtained an important market share, but now owing
to the change of times, its SCSIDE technology is no longer simply used to make
SCSI-to-IDE (SATA) Bridges that turn ATA/IDE (SATA) hard drives or ATAPI devices
into high-performance SCSI ones. The technology can be furthermore used to
design serialized, visualized and fit-for-network Bridges to connect more storage
devices and to do more transformations like SATA-to-SAS, Network-to-SATA/SAS,
etc. For these different applications, ACARD has given the technology a new name
SCSIDE II. That means the second generation of SCSIDE technology. Storage
products based on SCSIDE II are more practical and more popular.
Besides having the new functions of ACARD's IC, the series products of SCSIDE II contain
the technology of the first generation, too. In operation, SCSIDE II uses the built-in RISC
on the chip for interface transformation to lower the burden of CPU in data transfer, and
accordingly enhances the I/O performance, makes the whole system more stable and
more efficient. The applications of SCSIDE II on different storage devices are flexible and
steady. The prices of SCSIDE II products are also reasonable.
The reason of turning an IDE/SATA/SAS interface into a high-end, all-purpose
SATA/SCSI/Network one is that corporations have desired to get highly efficient and stable
interfaces for data transfer by using inexpensive storage interfaces so as to accomplish
the economy of costs. Obviously, SCSIDE II has the technological advantage and its price
meets the corporate budget. ACARD's series products of SCSIDE II are quite compatible
with Windows NT/2000/XP/Vista, Linux, Unix and Mac.
SCSI-to-SATA
The basic type of SCSIDE II is raising a SATA interface from 15.G to 3G. The SCSI
interface is raised to Ultra 320 too. Besides being applied to SATA devices for
transformation, SCSIDE II also supports the newest SATAPI devices for the transformation
of SATA to SCSI. Furthermore, the form factors of SCSIDE II products include the
industrial standards, too. In other words, such modularized products are specially
designed for industrial storage equipment.
