copying in RAID 5

Name: Anonymous 2007-05-07 4:36 ID:40AjGBj+

on a RAID 5 array copying a file from itself to itself takes forever. if i wanted to change how my array handles this situation, where would i begin? its hardware array, intel ICHR8. do i edit drivers? are they written in c++? is the source available?

my idea to speed it up:
lets say you have 4 drives A, B, C, D. choose a 4cycle permutation that sends each drive to another drive, like A->B, B->C, C->D, D->A. for each piece of the file on A, make copy of it on B. same time send piece from C->D. ...

this should run at half speed(for even number of discs) of writing into the array from another disk, as opposed to the long wait due to read/write commands interfering with each other.

where would i begin?
Probably not on 4chan
do i edit drivers?
That might prove hard
are they written in c++?
I'd guess C
is the source available?
Highly unlikely
rest
tl;dr

What are you talking about? Define "read/write commands interfering with each other" please.

i mean the commands on the drive may end up in a longer queue and spend more time waiting.

because some of the time the RAID will send a copy of a piece to the drive it origniated on
