I recently acquired a new client running SBS2003. The server was very low end with no reduntancy at all. The server's integrrated SATA controller does not support RAID. I suggested RAIDed hard drives and gave him the option of a SCSI or SATA implementations. We also discussed software mirroring. The client decided to go with a software mirror on both the boot and data volumes. I have not used Windows software mirroring. My concern is that if the "active boot partition" hard drive fails, that I will not be able to boot to the remaining intact hard drive because it is not "active". W2K server gave you the option of an Emergency Rescue Disk. My questions are: Are my concernes warranted? Or will the system "auto-magically" boot from the remaining drive with no intervention required? Do I need to create a bootable CD? If so, I've gone in circles looking for a decent, reliable boot CD solution. I haven't had much luck with this. Any solutions?
