Let me say this about firmware mirror: while virtually every BIOS will boot the "next" disk if the first fails, some will not fail over if the first drive is returning a parity but still returning data. Take that data any way you want, drive failure at power cycle is somewhat more likely than failure while running. > > * Can I use EVMS as a frontend? > Does it even use md or is EVMS's RAID something else entirely? > > * Should I use the 300s as a single mirror, or span multiple ones over > the two disks? > > * Am I even correct in assuming that I could stick an array in another > box and have it work? > > Comments welcome > > Thanks, > > Chris > - > To unsubscribe from this list: send the line "unsubscribe linux-raid" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- bill davidsen CTO TMR Associates, Inc Doing interesting things with small computers since 1979
