Is Raid mirroring on the Adaptec ATA-Raid 2400 supported on the hardware
level, or is it similar to software mirroring using CCD? I used external
SCSI raid systems with independant back-planes that do Raid with multiple
disks at the hardware level and yet appear as a single SCSI drive to a
SCSI controller. Is there anything similar for ATA (IDE) drives?
Also, on a side note, does anyone know of any hardware encryption system
that encrypts/decrypts at the disk block level with a single common
symmetric cipher key (like a triple-DES key generated from a hash of a
passphrase)? That way, one can use that to encrypt a harddisk, and yet
still be able to run any filesystem on it, and even the swap & partition
tables would also be encrypted, without any preformance loss. That seems
like something that would be easy to build using an ASIC (Application
Specific Integrated Circuit) chip into an IDE or SCSI controller.
Thanks in advance.
