3x 2720sgl raid5 same array?

[XxJessusxX]

Is it possible to have a single raid array over multiple controllers? For example if you had a nas with 3 highpoint rocketraid 2720sgl could you make a 24 drive raid array?

Thats card dependant. I'm not sure if you can span the array across multiple 2720's but I know on the 2320 you could.
