Re: [PLUG] Disaster Recovery Strategies

What you really want is a Raid-5 controller with a hotswap chassis for your
drives. 3Ware makes excellent hardware with linux source drivers as well.
It's expensive, but if you want true single-drive-failure-zero-downtime
operation, it's the way to go, IMHO. Raid5 has saved my butt on more than
one occasion.
