Link aggregation was designed to give you the option of increasing available network bandwidth and resiliency, without completely changing your infrastructure to do so (with the cost that such a move would entail).
Modern Hard drives have an internal mechanism called S.M.A.R.T. through which it is possible to know when a hard disk is about to fail. Wouldn’t it be nice of the server to Email you before such a failure?
Do you need a file server on the cheap that is easy to setup, “rock solid” reliable with Email Alerting? will show you how to use Ubuntu, software RAID and SaMBa to accomplish just that.
Of course, this technique is meant for real servers, but if you’ve got a Linux box sitting in your house acting as a home server, you can use it there as well.
