HDD Read Ahead Cache:
This option allows the users to disable the cache of the HDDs on 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.
HDD Queue Depth:
The queue depth is the number of I/O operations that can be run in parallel on a disk drive. HDD
Queue Depth options are 1, 2, 4, 8, 16, and 32.
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):
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.
Disk Write Cache Mode:
The internal RAID controller supports Disk Write Cache Mode options: Auto, Enabled, and Disabled. If the
RAID subsystem has BBM (battery backup module), selecting the Auto option will automatically
enable Disk Write Cache. On the other hand, if there is no BBM, the Auto option will disable Disk Write
Cache.
Disk Capacity Truncation Mode:
The internal RAID controller use drive truncation so that drives from different vendors are more
likely to be able to be used as spares for each other. Drive truncation slightly decreases the
usable capacity of a drive that is used in redundant units. Options are:
Multiples Of 10G
: If you have several 120GB drives from different vendors, chances are
that the capacity varies slightly. For example, one drive might be 121.1 GB, and the
other 120.4 GB. This drive truncation mode makes the 121.1 GB and 120.4 GB drives
same capacity as 120 GB so that one could replace the other.
Multiples Of 1G:
If you have 120 GB drives from different vendors, chances are that the
capacity varies slightly. For example, one drive might be 121.1 GB, and the other 121.4
GB. This drive truncation mode makes the 121.1 GB and 121.4 GB drives same capacity
121 GB
so that one could replace the other.
No Truncation
: The capacity of the disk drive is not truncated.
