PA Sport Redpath resigned as Gloucester boss in April and the club threatened legal action if they discovered an approach from the Sharks was behind the decision, something Sale chief executive Steve Diamond unequivocally denied.
Diamond said on the club's official website: "Anybody who knows what happened at our club in the last 15 months will be aware that we termed it 'Year Zero', and that was just the start."
He added: "Looking to the future, we have a number of good players joining us. What I've always wanted since returning to the club was a proven coach in the Aviva Premiership, and in Bryan Redpath that's exactly what we've got.
"Bryan became available from Gloucester at the end of last season. As soon as he did, we were keen to talk to him. Following our discussions he agreed to be our director of rugby, and we are delighted."
