Joanne,
I would suggest a larger HW system. This is now a a days a very typical configuration for a Notebook. For a server I would suggest 4-CPU's with min 32Gigs to start.
Review the sizing guide for more details:
Sizing and Deploying SAP BI 4 and SAP Lumira
There are many factored to consider, such as:
- # of users, type of users, tools used
- Typical type of source, for BW need additional memory for DSL Bridge
- Review the guide for more details
Regards,
Ajay
