All the supported combinations for IBM storage can be found in the IBM System Storage Interoperation Center (SSIC).
For Linux on z the best way to get the number of combinations down is to first select "IBM z Systems" as the host platform and then continue with the storage family.
Very important: if your combination isn't listed there, please get a "Request for Price Quotations (RPQ)" submitted by your IBM rep as described on the SSIC start page.
