Migration of BW to HANA Data Base

Hi Experts,

For Migration of BW 7.3 SP7 to HANA Data Base , I would like to know procurement details for HANA data base.

suppose current Database used by BW in production is 468GB (51%), assuming for HANA database (ROW and column store) it may require say 350GB space.

In that case , how many CPUs will be required??

as per details i believe , production system can be only on 1 HANA DB, and for Dev. and Quality we may require separate HANA BOX.

Also, w.r.t. Master and slave, at least 2 BOX are necessary (since scale out option is possible).

So does that mean , total 4 BOX are required?? or 2 HANA BOX are enough, may be of T-shirt size 'M' 4 CPU sockets.

Please correct me if this is not the case..

Thanks and Regards,

Amit.
