NVIDIA MediaShield Features
Additional RAID Features
NVIDIA MediaShield 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 MediaShield 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.
• Bootable RAID
This allows you to install the operating system onto the RAID volume.
• Migrating
Migrating 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 migrating feature gives the user an
upgradeable option to manage storage easily.
