ASRock Rack EPC621D8A Installation guide

  • Hello, I'm your chat assistant. I have reviewed the user manual and am ready to assist you with questions about installing and configuring SATA Hard Disks with RAID. This manual contains details on working with RAID levels 0, 1, 5, and 10, as well as using Intel Rapid Storage. Feel free to ask me anything.
  • What RAID levels are supported?
    What is the minimum number of hard drives required for RAID 10?
    What is the primary purpose of RAID 1?
    What is the recommended drive configuration for RAID 0?

RAID
Theterm“RAID”standsfor“RedundantArrayofIndependent
Disks”,whichisamethodcombiningtwoormoreharddisk
drivesintoonelogicalunit.Foroptimalperformance,please
installidenticaldrivesofthesamemodelandcapacitywhen
creatingaRAIDset.
RAID 0 (Data Striping)
RAID0iscalleddatastripingthatoptimizestwo
identicalharddiskdrivestoreadandwritedata
inparallel,interleavedstacks.Itwillimprovedata

WARNING!!
AlthoughRAID0functioncanimprovetheaccessperformance,
it does not provide any fault tolerance. Hot-Plug any HDDs of
theRAID0Diskwillcausedatadamageordataloss.
RAID 1 (Data Mirroring)
RAID1iscalleddatamirroringthatcopiesand
