STORAGE SIZING - running R/3 ECC 9 yrs - how to estimate NW2004s 7.0 need

[Former Member]

Does anyone have some metrics they use when determining storage requirements if one were to plan on installing almost all of the NW2004s product suite.

Example ---

<u>BACKGROUND DATA</u>

We've been running ECC 5.0 (previously 3.1H, 4.6C) for 9 years.

Total "PRD" storage usage for ECC = 1.5tb

Total storage available in our environment = 8.6tb

We traditionally have an additional 2 full copies of PRD data for QA/TST etc.

% of PRD storage use against total available = 17.4% (1.5tb/8.6tb)

Our ECC 5.0 grows approximately 350gb per year (with archiving active)

<u>FUTURE STATE</u>

We plan to implemnt BI, CRM, SCM, SRM, MDM, KM, XI, APO

Need to plan out 3 yrs storage requirements for these additional components.

Yes, we realize "IT DEPENDS" but need to make some assumptions and put a stake in the ground.

Does anyone have some storage metics where

CRM storage = x% of R/3 storage

BI storage = x% of R/3 storage

SCM = x% of R/3 storage

SRM = x% of R/3 storage

etc.

Any feedback is greatly appreciated......

You can use SAP's "QuickSizer" tool:

Hello Doreen!

Yes, it DOES depend...

CRM etc.: No idea. We dont have them.

BI 7.0 starts with some 30 GB (new system) and grows into infinity, depending on the creativity and detail requirements of your BI people. Can be much larger than production ERP data, we hear. My tipp: Always keep HUGE room to grow for the BI database, the increments are not by hundreds of MB, but by dozens of GB, if you are lucky... And our guy did never tell when they began to load a new cube...

Buying storage for 3 years seems a bit long for me, as disk sizes double so often... Our collegues are now migrating out the 36 GB drives they put in in 2002, and 72 GB are the next ones to go. And the 600's are ante portas...

What storage system do you have?

Server sizing: Dont ask me. We alwas had luck to take it one size larger than "they" sized. But that depends on your workload growth rates.

HTH, Rudi
