The question is do you Need a certified data erasure or you just want to make sure there is no usable data on it.
If you Need a certified erasure contact emc sales and ask for a quote.
If you just want to make shure that the dat is unusable. Create a new pool and luns . Attach one Server to the Array, assign the lun to it and then run any Kind of open source erasure tool . Afterwards you can just delte the luns and pools.
