To be honest, although almost every good RAID controller is the same in the case of a single drive failure in a two-disk RAID 1 array. A smart array is a real hardware RAID controller, so any one drive may fail, and the operating system can still work as fast as using two drives. If you have a software-based RAID controller (e.g. some cheaper Promise model), then you sometimes need a boot floppy to force boot from the second drive.
HP Smart Array is a very good RAID controller, fast, very reliable, and simple to use. They are definitely My favorite embedded RAID controller. An important feature they have is the ability to pull a set of drives from one system and paste them into another system for recovery and other purposes. When you show them how to control from different Many other RAID controllers will become very confused when the array is pulled out by the controller, not smart arrays. They just work!
I have an HP Proliant server with a Smart Array P400 RAID controller, equipped with two 146GB 10k SAS hard drives, configured as a mirrored RAID configuration. Where can I find information on how a drive failure affects this configuration? I look forward to seeing how this RAID configuration and hardware react to drive failures.
