(i.e. what kind of > processor, do they have a parity engine, etc.) "it varies" I've heard tales of at least three different hardware platforms; I have two myself, one is the LSI 1015 (dual U160 + ARM7 on a chip), the other is a custom Compaq blob which is, I think, a PowerPC, and some variants of this I've seen have other Compaq blobs which could well include a parity engine. As controllers go, they seem to be a bit of a mixed bag. Basic behaviour and performance isn't abominable (though as you've pointed out, I appear to be letting them down badly), but from what the Y! people have said, some units behave differently from others. 8/ -- To announce that there must be no criticism of the president, or that we are to stand by the president, right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public. - Theodore Roosevelt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
