Hardware Command Queuing

Queuing increases data performance, particularly when
random accesses are frequent. The most noticeable
performance increases are I/Os per second. The PCI card
features embedded hardware support for ATA-7 Tagged
Command Queuing and SATA-II Native Command
Queuing. The queuing engine operates in synchroniza-
tion with each attached drive for the fastest possible
ordering and re-ordering with the out of sequence
command operations.

Hardware Direct Memory Access

An advanced, embedded hardware DMA engine reduc-
es the amount of communication and time normally
required by the PCI bus to control an ATA-based device.
This increases data performance, particularly in a data
streaming environment, such as video streaming.

Hardware RAID Acceleration

Hardware RAID acceleration improves RAID perfor-
mance and scaling throughput as activity is increased.
Each port on the PCI card includes a dedicated RAID
engine that can participate in a JBOD or a RAID volume.

RAID Manager

RAID Manager for Windows is powerful, yet easy to use
software that lets you:
• Create and delete multiple RAID volumes;
• Monitor the details and health of a RAID volume.
