WebParity is a calculated value used to reconstruct data after a failure. While data is being written to a RAID-5 volume, parity is calculated by doing an exclusive OR (XOR) procedure on the data. The resulting parity is then written to the volume. The data and calculated parity are contained in a plex that is "striped" across multiple disks. WebRAID-5 has the simplest strategy to describe. On the parity disk, you store whether the number of '1's on all the other disks at this position is odd or even. This is a binary piece of data (odd or even, 1 or 0) and the XOR CPU instruction can … WebApr 12, 2024 · Call of Duty. ️: Modern Warfare. ️ II & Warzone™️ 2.0 Season 03 Patch Notes.
