How do I ensure redundancy across Promise* ATA 100 RAID controllers?
When creating a RAID array using the Promise* ATA 100 RAID controller, keep in mind redundancy can only be obtained when your drives are spread across the two channels. You cannot obtain redundancy if you have a Master / Slave configuration on a single channel. In order for a redundant array to be valid, a Master / Master configuration should be used or a Master with Slave & Master with Slave configuration.
If you have a Master / Slave on a single channel and the master driver goes off-line, your slave drive will also go off-line. Data will not be lost, but your RAID array will be unavailable and this could cause unwanted downtime on your server.
