USB and eSATA to SATA II RAID Subsystem
59
Installation and Configuration Manual
Maximum SATA Mode Supported:
The 4 SATA drive channel can support up to SATA ll, which runs up to 300MB/s. NCQ is a command
protocol in Serial ATA that can only be implemented on native Serial ATA hard drives. It allows multiple
commands to be outstanding within a drive at the same time. Drives that support NCQ have an
internal queue where outstanding commands can be dynamically rescheduled or re-ordered, along with
the necessary tracking mechanisms for outstanding and completed portions of the workload. RAID
subsystem allows user to choose the SATA Mode: SATA150, NCQ, SAT300, NCQ.
Host NCQ Mode Setting:
This option allows the users to select the supported Host NCQ Mode or to disable it. Options
are: ESB2/MACPro/SiliconImage, Marvell 6145, ICH, nVidia, and Disabled.
HDD Read Ahead Cache:
This option allows the users to disable the cache of the disk drives in the RAID subsystem. In
some HDD models, disabling the cache in the HDD is necessary to prove the RAID subsystem
functions correctly.
Volume Data Read Ahead:
This option allows the users to set the Volume Data Read Ahead function. Options are: Normal,
Aggressive, Conservative, and Disabled.
Stagger Power On Control:
This option allows the RAID subsystem’s power supply to power up in succession each HDD in
the RAID subsystem. In the past, all the HDDs on the RAID subsystem are powered up altogether
at the same time. This function allows the power transfer time (lag time) from the last HDD to
the next one be set within the range of 0.4 to 6.0 seconds.
Spin Down Idle HDD (Minutes): MAID Function
This option enables the hard drives to spin down after they become idle after a preset period of time.
Options are: Disabled, 1 (For Test), 3, 5, 10, 15, 20, 30, 40, and 60.
Empty HDD Slot LED:
Use this option to turn ON or OFF the LED of a slot with no HDD.
HDD SMART Status Polling:
The RAID subsystem can read HDD SMART information through this function. This function is
enabled by default.
Auto Activate Incomplete Raid:
Use this option to automatically activate an Incomplete Raid Set. Note that the Raid Set status
becomes Incomplete when one disk is removed or failed in power off state. After activated, the
Volume Set(s) in the Raid Set will be in Degraded mode.
