I don't use the raid features on these cards as the mix of hard drives I have doesn't allow it. I do have about 7 drives attached to each controller in varying sizes. Each drive is configured as a raid 0 array. The cache is set to read only and is purely there to allow for the amount of raid 0 arrays I have. The smart arrays can not do JBOD or pass through.
If a drive fails or is showing signs of failure I can pull it and plug it in via USB. It doesn't have any special raid configuration or disk format so I can get at the data easily.
I had a cache module fail the other week which took the whole controller offline until I replaced it. Removing the faulty cache disabled the arrays and therefore disk access. This is something I hadn't foreseen but luckily I had a spare cache module. I now have two more controllers on the way with cache and batteries attached.
I suppose my position is to be resilient as possible.
- If I drop a disk, replace it.
- if I drop a controller or the cache module, replace it but have downtime while I wait for parts.
If a feature is developed it would be great as the controller being offline will not stop access to any file.

Just a quick feature request, unless someone can explain how to do this with the current version.I would like to place duplicated files on different storage controllers. I have 2 x HP Smart Array p410's with about the same amount of storage on each controller.- from my perspective write performance for files going to different controllers should be faster than a file being duplicated onto the same controller.
- if a controller fails I have a cope of all of the data and nothing stops working.
- read performance could also be better as the file will be coming from two different paths, with two sets of controllers, cache involved.The only way I can think of doing this is the create a pool of drives for each controller, then mirror them with either Windows or a third party tool or even create a nest drive pool out of the two other pools.Thanks

Deactivate the license on WHS first. Then move the drives. Should be very easy. I did the same upgrade a few months ago and then moved to 2012 R2 within a couple of days and had a licensing issue trying to activate and couldn't until I had deactivated.
