It's quite clear to me how the crypto layer works, and data send /written to the SSD cache only gets there in encrypted form when the SSD part is used as a disc cache exclusively. I'm not quite good in explaining things, I guess :-) I'm just curious if this SSD part is "just a cache", or maybe something else, as e.g. an additional "drive" with its one device, or a mixture of that... That wasn't quite clear to me. There's some articles out there which describe this SSD part as a "cache only" area, just like the cache which commonly is used with any harddisc drive, and I've read a report which described this area as a kind of "additional drive" which gets used as a cache at the same time, just if you would store your linux swap on an extra harddisk. Don't know if you can follow me now, blame it on me in this case, thinking "'round the corner" :-) _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
