This is not true. You can transport these drives to another system with either a Perc, or any other form of LSI MegaRaid. What's more, I'll advise staying away from generic SATA, because they're impossible to transport to any system which is more advanced than generic SATA. ;-) See? It works two-ways. And the same is true of all the other HBA's out there which have any intelligence in them, too ... RealTek and so forth. It's all not compatible with each other. Realtek drives have to stay with realtek controllers. LSI drives with LSI controllers. Generic SATA with generic controllers. Etc. One advantage of using the Perc, or some other HBA with battery backed write-back cache, is a really big performance benefit for sync writes... But not quite as big a benefit as using the dedicated log device ... But the HBA is far lower cost than the SSD solution, and doesn't take up a drive slot (or two). _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
