    It means, "FUCK. I should be running Solaris with ZFS on this box. RAID on small servers is so lame."

    Downtime is impossible to prevent.

    raid is just one piece in a highly available solution. in looking for a solution to maximize uptime, you want to remove any single points of failure.
    - redundant disks through RAID
    - redundant controllers to disk
    - redundant power supplies connected to separate PDUs which are connected to separate UPSs, either of which across the board can handle a failure (this is one reason why the Sun 880/890 sucked, it had 3 power supplies, so you couldn't connect it to 2 power sources without a special PDU in between)
    - redundant servers in a cluster or an equal or better fault tolerant solution like load balancing across multiple hosts



    my preference is a Sun T-series machine with 2 Emulex fiber cards connected to redundant Brocade fiber switches (that are configured as 2 isolated fabrics) connected to Hitachi USP storage and running Veritas Storage Foundation HA (VxVM, VxFS and VCS). i guess DMP for redundant paths. i can go either way for root disk mirroring, Disk Suite/Sun Volume Manager or VxVM encapsulated root (it isn't so bad if you do it right and properly create all of the slices).
