SMARTCor. Functions -2 SMARTCor. Functions -2 Disk Scrubbing (DS) Run-time data parity checking Run-time data re-generate and white-back when parity error (WR back to the same address, HDD do the remap) Bad blocks remapped in advance Largely reduce the frequency of “bad block remap” message from RAID controller w w w .easyRAID.com - 4 -
SMARTCor. Functions -3 SMARTCor. Functions -3 Smart / Disk cloning SMART for HDD health monitoring 1 spare HDD to clone “un-healthy” HDD reported Switch to this cloned HDD when this un-healthy HDD fails. Use 2 HDDs – 1 for parity, 1 for cloning, for data fault tolerant. Same number as R6 Better performance than R6, no performance penalty w w w .easyRAID.com - 5 -
