CHAPTER 1About NVIDIA® MediaShield StorageNVIDIA MediaShield–Additional RAID FeaturesNVIDIA MediaShield offers the following additional features:• Free Disk and Dedicated Spare DiskA Free Disk or Dedicated Disk can be automatically used in case one drive of a faulttolerantarray fails. NVIDIA MediaShield defines a fault‐tolerant array as either RAID1, 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 RAIDThis allows you to install the operating system onto the RAID volume.• MigratingMigrating is the ability to convert from one RAID mode to another RAID mode. Thisallows the user to upgrade their current disk or array for better performance, highersecurity, and increased capacity. More importantly, this is accomplished withouthaving to go through multiple steps. The migrating feature gives the user anupgradeable option to manage storage easily.• Disk Failure IdentificationThe NVIDIA MediaShield application includes a disk alert feature that provides agraphical indication of the status of the hard disks in the system. It notifies you when adisk fails and indicates which one to replace.• Self Monitoring Analysis and Reporting Technology (SMART) lets you monitor thehealth of the drives in the array at regular intervals.NVIDIA Corporation 7
