|

intelligently mixes live access for the disks being repaired with
|
||||
snapshot access for reference disks to maintain mathematical
|
||||
integrity across the array.
|
||||
* Implemented AVX-512BW (Byte and Word) support for parity generation
|
||||
and data recovery, optimizing performance on modern architectures
|
||||
like Intel Sapphire Rapids and AMD Zen 4/5.
|
||||
By scaling to 512-bit ZMM registers, the implementation now processes
|
||||
64 bytes per iteration, effectively doubling the data width of the
|
||||
previous AVX2 routines.
