The RAID controllers also tend to support more SATA features like NCQ, hot-swap, monitoring, etc. They also enable you to use the same hardware across OSes (FreeBSD, Linux, etc). For example, we use 3Ware controllers in all our servers, as they have good, solid support under FreeBSD and Linux. On the Linux servers, we use hardware RAID. On the FreeBSD servers, we use them as SATA controllers (Single Disk arrays, not JBOD). Either way, the management is the same, the drivers are the same, the support is the same. It's hard to find good, non-RAID, SATA controllers with solid FreeBSD support, and good throughput, with any kind of management/monitoring features. -- Freddie Cash [email protected] _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
