On a side tangent. At WAVV, one of the speakers said you never want to do software encryption. The performance impact will eat you up.
Of course, I disagree. In my book, it all depends on how much you want to encrypt. I'll do it with spare cycles now, and pay for a hardware solution when there is a payback. Your mileage and experiences may differ. So, when you do software encryption (such as for DDR), how much more processor time do you see? (over a standard DDR disk to tape) Double? Tripple? 10X?
