3 way mirroring and disk destaging

Hi

Do any of the Smart Array, MSA1000 or EVA3000 systems allow me to create 3way mirror sets and has the capability to allow me to split a mirror and destage it for transport whilst system still running and yet maintain a fully redundant 2way mirror set?

Most arrays seem to be support ADG to improve availability but this doesn't help my problem

Thanks

Sadly the times of HSGXX storage systems have passed already... None of the above mentioned boxes supports something like that on the HW level.

Re: 3 way mirroring and disk destaging

Is there any kind of smart array host scripting interface like the old hszterm software?

It looks like there is a very primitive way to set/get the configuration of a SmartArray controller through a ACU command line (it's meen mentioned 2 or 3 times here on ITRC; no link at hand, sorry), but I've seen nothing that indicates a real CLI like on most HSx controllers.
