JBOD probably isn't dead, simply because motherboard manufacturers are unlikely to pay the extra $10 it might cost to use a RAID-enabled chip rather than a plain chip (and the cost is more if you add cache RAM); but basic RAID is at least cheap.
NVidia MCPs (later NForce chipsets) also do RAID. The NForce 5x0 systems even do RAID-5 and sparing (with 6 SATA ports). Using special-purpose RAID chips won't be necessary for desktops or low-end systems. Moore's law says that we can continue to integrate more and more functions onto fewer parts.
Of course, having RAID in the HBA is a single point of failure!
At this level, and price point, there are many SPOFs. Indeed there is always at least one SPOF. -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
