I suggest the IBM ServeRAID controller as one solution for SCSI. I have a bunch of servers in various places around the country, and these have been good to me, work pretty well with typical failures, and IBM supports them. I've deployed about 35 of these and am still happy, so you have a data point. Most of my servers have 3-6TB. -- bill davidsen CTO TMR Associates, Inc Doing interesting things with small computers since 1979 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
