1. Introduction
1. Introduction
The ASUS PCI-DA2100 is a PCI to SCSI RAID controller specifically designed to
provide RAID 0, 1, 3 or 5 capability to any host system equipped with Little Endian
PCI Local Bus interface. All the RAID functions of ASUS PCI-DA2100 are per-
formed by a 486 CPU coupled with high-speed DRAMs and firmware in Flash
Memory. In effect, it endows the host system with the high performance and fault-
tolerant disk storage operation of RAID technology. It is also an ideal solution for
weaving several hard disks into one contiguous volume.
The ASUS PCI-DA2100 has a comprehensive drive failure management that allows
automatic bad block reassignment when a bad sector is encountered during a write.
Hot-swapping is supported through automatic detection of failed drives, followed
by either automatic background rebuilding onto a spare if a spare is assigned or
manual replacement of failed drive and manually initiated background rebuilding.
And all these failure recovery operations are performed in a way transparent to the
host.
The controller has been designed with the ease of integration and maintenance in
mind. The major features are described in the following section. The ASUS PCI-
DA2100 already includes all the major operational requirements for a RAID sub-
system. The final features of a fully-built RAID subsystem will, however, depend
on the actual components used and the creativity of the integrator.
