CompactFlash RAID Card With ATA Host Interface?
|
|
|
| I'm looking to a firewall from ATA hard drives over to booting from a
CompactFlash, and then writing logs and other real-time files to a separate
hard drive. I have seen many small (2 inch by 2 inch) boards that will
convert ATA to CF interfaces, sometimes for two CF cards on one board.
Has anyone found an ATA to CF converter that will also do RAID-1 in
hardware, so that you could have a fully redundant CF pair, which looks to
the host just like a normal ATA drive attached to its existing ATA
interface?

The ATA-to-CF cards are no more than a pin layout converter, there's no
intelligence on them whatsoever. If you get two of these, you should be able
to use any RAID-1 mirroring solution (either hardware or software) to create
a RAID set, just as if they were ordinary harddisks.

In this application, I was trying to use these on a proprietary box with
proprietary software and there probably isn't much chance of my adding in a
hardware RAID controller that works on the PCI bus and requires OS support.
