I highly recommend taking a look at Openfiler, pretty simple to set up and very flexible, really just a stabilized/tested "appliance" built on Linux/FOSS tools. Then your choices come down to what top-of-the-line hardware you'd like to buy. . . With the money you'd save from not going COTS, you could build two of them and create high-availability mirrored servers with DRBD/heartbeat for extra redundancy/fault-tolerance. And pre-pay for a full lifetime of support, if that gives you and the company an extra level of comfort. And still have a nice chunk of budget left over for UPSs, backup hardware, network capacity expansion etc. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
