I am setting up a raid10 array, using two md1000 enclosures, and the two channels on a perc6e.
What is the best performing way to place the drives across the channels?
Should I add the drives sequentially, so that sequential stripes are on the same channel?
Should I alternate enclosures with each striped pair, so that each stripe alternates channels?
Or, should I alternate enclosures with each drive, so that mirrored pairs are split across the channels?
Also, once RAID is created, is it possible reconfigure the arrangement, without losing data?
