CHAPTER 1 About NVIDIA RAID NVIDIA RAID Features Additional RAID Features NVIDIA RAID offers the following additional features: • Free Disk and Dedicated Spare Disk A Free Disk or Dedicated Disk can be automatically used in case one drive of a faulttolerant array fails. NVIDIA RAID defines a fault-tolerant array as either RAID 1 or RAID 0+1. 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. • RAID Across PATA and SATA NVIDIA RAID can span across both Parallel ATA as well as Serial ATA controllers. RAID operations can be performed on Parallel ATA hard drives, Serial ATA hard drives, or both Parallel and Serial ATA hard drives. • Bootable RAID NVIDIA RAID can be configured in a way to make it bootable. For example, two hard drives can be configured as a bootable mirrored RAID array. • RAID on Multiple Disk Controllers Unlike other RAID solutions that limits the user to a dedicated RAID controller, NVIDIA RAID software can use a drive on one RAID controller and another drive on a second RAID controller. • 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 without having to go through multiple steps. The morphing feature gives the user an upgradeable option to manage storage easily. • Hot Plug Array Hot plug, with respect to RAID, is the ability to add a disk to a system safely and without causing problems for the RAID software. For example, when a drive in a mirrored array fails, a user can launch the Hot Plug Array Wizard which instructs the user as to when a drive can be added safely to the system. As soon as the drive is added, the user can then finish running the RAID wizard and the drive becomes useable by the system. NVIDIA Corporation 9

About NVIDIA RAID
NVIDIA RAID Features
Additional RAID Features
NVIDIA RAID offers the following additional features:
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 or
RAID 0+1. 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.
RAID Across PATA and SATA
NVIDIA RAID can span across both Parallel ATA as well as Serial ATA controllers.
RAID operations can be performed on Parallel ATA hard drives, Serial ATA hard
drives, or both Parallel and Serial ATA hard drives.
Bootable RAID
NVIDIA RAID can be configured in a way to make it bootable. For example, two hard
drives can be configured as a bootable mirrored RAID array.
RAID on Multiple Disk Controllers
Unlike other RAID solutions that limits the user to a dedicated RAID controller,
NVIDIA RAID software can use a drive on one RAID controller and another drive on a
second RAID controller.
• 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 without
having to go through multiple steps. The morphing feature gives the user an
upgradeable option to manage storage easily.
Hot Plug Array
Hot plug, with respect to RAID, is the ability to add a disk to a system safely and
without causing problems for the RAID software. For example, when a drive in a
mirrored array fails, a user can launch the Hot Plug Array Wizard which instructs the
user as to when a drive can be added safely to the system. As soon as the drive is
added, the user can then finish running the RAID wizard and the drive becomes
useable by the system.
