How many No of boxes should be deployed approximately for about 100-120 plants or 35-40 countries for a production giant.
How do u calculate or estimate this?
Thank u.

Hi Shyam,
First of all, the "number of boxes" needed will be depending on some parameters like: How many HANA-landscapes you will need (Geographical, Business, Data Center or SAP Landscape division), and how many HANA per landscape (eg DEV-QAS-PRD of only DEV-PRD)? Also do you need High Availability and Disaster Recovery scenario?
But the first considerations you or your company need to think about are: What are the business-scenario's for using SAP HANA? Do you want to develop SAP HANA Native-applications or ABAP-based applications on HANA or both (hybrid)?
Then you need to choose between (one or more): SAP HANA stand-alone (side-car), SAP BI on HANA and SAP Business Suite on HANA.
From there you will get enough input to choose between those scenario's, gathering the requirements regarding the needed versions (maybe need EhP upgrade or SP-upgrade) and also your implementation scenario's (Upgrade/Migration/Fresh-install).
Then you could start to think about the sizing, finally....;-) Because then you know what will be the source of your SAP HANA en the specific scenario's for your company.
There are some methods to perform the sizing, for example this doc: http://scn.sap.com/community/hana-in-memory/blog/2013/01/17/sap-hana-sizing
Also this BW-specific sizing doc:http://www.saphana.com/docs/DOC-2531
I hope this will help you.

Hi Shyam,
The sizing depends on your Current data and how much can it be compressed
You can run script or ABAP programs to determine HANA sizing.
For HANA Sizing, check:

For BW on HANA Sizing, check:
