Additional RAID Features

NVIDIA RAID offers the following additional features:

vFree 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.

vBootable RAID

This allows you to install the operating system onto the RAID volume.

vMorphing

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.

vHot 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.

. 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",
