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.

Features and Benefits Summary

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.

Disk Failure Identifica- .Notifies the user when a disk fails and indicates which one to

tion

replace.

Hot Plug Array

. Allows the user to safely add a drive to the array when needed.
