SAP BW IDES on HANA Size

Question

Please can someone let me know what is the minimum / recommended size of BW IDES server (RAM, CPU and Hard-drive) with HANA. I have checked SAP note on sizing but cannot figure out how do we calculate the size.
I would need size in following cases
a) Assuming nascent state with say just the Business Content of FICO, SD and some other areas installed, say about 100 cubes etc.
b) Size increase for each 100 million records loaded from source. Assume 30 fields each with 10 Bytes.
(I can do 10010^630*10), but should this change (because of column store)
Thanks in advance.

Answer 1

Ferry, I think the correct note is 1637145 according to which
A cleansed BW system usually has about 60 GB of database tables that will be
stored in row store (data dictionary, housekeeping tables, etc.).
u2022 Average compression factor database table size : row store size = 1.5 : 1
 A fixed amount of 40 GB for row store data for BW is assumed.
u2022 HANA uses additional caches to accelerate I/O to persistence layer and for other
purposes. These caches can grow but will shrink if memory is needed to store
data. However, a minimum amount of cache memory of 40 GB has been
identified.
u2022 Additional HANA components (statistics server, name server) require 10 GB of
memory.
u2022 Sum of memory not covered by column store: 90 GB
So I am a bit confused about your conclusions because it clearly speaks in terms of 60GB for dd and housekeeping alone.
