Queuing
Native Command Queuing (NCQ) is a technology designed to increase performance of SATA hard disk
drives by allowing the individual hard disk to internally optimize the order in which received read and
write commands are executed. This can reduce the amount of unnecessary going back-and-forth on the
drive's heads, resulting in increased performance for workloads where multiple simultaneous read/write
requests are outstanding, most often occurring in server or storage-type applications. Without NCQ the
drive has to process and complete one command at a time. For NCQ to be enabled, it must be
supported and turned on in the controller and in the hard drive itself.

Dual Domain Support
Dual Domain SupportDual Domain Support
Dual Domain Support
Dual domain SAS creates redundant pathways for external drives from servers to storage devices. The
redundant paths created by these configurations reduce or eliminate single points of failure within the
storage network. This provides increased levels of high availability with redundant paths from the
controller to the drives. Dual domain SAS implementations make it possible to tolerate host bus adapter
(HBA) or controller failure, external cable failure, expander failure, cable pulls, expander failure and
failure in a spanned disk (JBOD) environments.
