Host The computer system in which a SCSI host adapter is installed. It uses
the SCSI host adapter to transfer information to and from devices
attached to the SCSI bus.
Host Adapter A circuit board or integrated circuit that provides a device connection to
the host.
Integrated RAID
(IR) Solution
The LSI Integrated RAID solution provides either the Integrated Mirroring
(IM) solution, which provides features of RAID 1 and RAID 1E, or the
Integrated Striping (IS) solution, which provides features of RAID 0.
Integrated
Mirroring (IM)
Solution
The LSI Integrated Mirroring (IM) solution provides features of RAID 1
and RAID 1E. The IM feature provides data protection for the system
boot volume to safeguard critical information such as the operating
system on servers and high performance workstations. The IM feature
gives customers a robust, high-performance, fault-tolerant solution that is
less expensive than a dedicated RAID controller.
Integrated
Striping (IS)
Solution
The LSI Integrated Striping (IS) solution provides features of RAID 0. The
IS feature is a low-cost solution with many of the features of a more
expensive RAID striping solution. A single IS logical drive may be
configured as the boot disk or as a data disk.
Internal SCSI
Device
A SCSI device installed inside the computer cabinet. These devices are
connected to one another with an unshielded ribbon cable.
PCI and PCI-X Peripheral Component Interconnect. A high performance local bus
specification that allows connection of devices directly to computer
memory. The PCI Local Bus allows transparent upgrades from a 32-bit
data path at 33 MHz to a 64-bit data path at 33 MHz; from a 32-bit data
path at 66 MHz to a 64-bit data path at 66 MHz; and from a 32-bit data
path at 133 MHz to a 64-bit data path at 133 MHz (1064 Mbytes/s peak).
PCI Express PCI Express is the third generation high performance I/O bus that
interconnects peripheral devices. PCI Express replaces parallel PCI bus
with a highly scalable, fully serial interface. PCI Express takes advantage
of recent advances in point-to-point interconnects, switchbased technology,
and packetized protocol to deliver new levels of performance and features.
Peripheral
Device
A piece of hardware (such as a disk drive, printer, or CD-ROM) used with
a computer and under the computer’s control. SCSI peripheral devices
are controlled through a SCSI host adapter.
