I suspect that some motherboards just accept the ECC memory bits from RAM and quietly ignore them, no communication with anything the CPU can read if an ECC error does happen. I know of several organizations I've worked with in the past that would just quietly leave out the ECC-interrupt line in the interests of "simplification for end users" as the resident MBAs would have said. My background is hardware, and offhand I can't think of any way that software could fix ECC errors from system RAM if it didn't get notified somehow that one had happened. That doesn't mean there's no way it could happen. I'm all over the software repair of bad disk data, though. That's one of the prime motivators for zfs for me. In that case the checksums are stored in disk where the cpu can get at them. Can you point me to a reference?? Anyone? That would open up some less expensive hardware if true. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
