Additional RAID Features
NVIDIA RAID offers the following additional features:
v
Free Disk and Dedicated Spare Disk
A Free Disk or Dedicated Disk can be automatically used in case one drive of a
fault-tolerant array fails. NVIDIA RAID defines a fault-tolerant array as either
RAID 1, RAID 0+1, or RAID 5. A free disk can be used by any available fault-
tolerant array, while a dedicated disk can be used only by the array to which it is
assigned.
v
Bootable RAID
This allows you to install the operating system onto the RAID volume.
v
Morphing
Morphing is the ability to convert from one RAID mode to another RAID mode.
This allows the user to upgrade their current disk or array for better performance,
higher security, and increased capacity. More importantly, this is accomplished
withouthaving to go through multiple steps. The morphing feature gives the user
an upgradeable option to manage storage easily.
v
Hot Plug Array
A nice flexibility feature is the ability to move MediaShield RAID arrays from one
nForce system to another. Since most nForce systems support SATA hot plug
capability, you can add/remove a RAID array even while the system is running.
This is done using the Hot Plug Array wizard.

Benefits
. Allows the user to dedicate a "spare" disk as a hot standby
in the event of a array failure.
. Offers additional protection in case of a failure in a mirrored
array.
. Supports the use of a RAID drive for loading the operating
system at power up for optimal performance
. Allows the user to upgrade for more performance, security,
and capacity.
. Allows the user to change the current state of a disk/array to
another array with a one step process called "morphing",
without losing any data during the configuration change.
. Notifies the user when a disk fails and indicates which one to
