SharePoint 2010 Architecture Help

Hi Guys,

I need your help in designing the architecture for optimize performance and low turn around time and high throughput.

Requirements:

1) Users: around 2000

2) High response time: around 3-4 seconds

3) Live Data size of around 600 GB (Data coming from two different systems into SharePoint)

4) Highly customize website with third party integration

5) Highly robust and high performance website

I need help in designing the architecture to handle 600 GB of data and still give high response time. Since all the data is critical and accessed on daily basis. So, architecture should be robust.

As per my analysis, I came up with the following architecture

2 WFE Server with 8 GB RAM each and C 60GB, D 60 GB each along with 6 core architecture

1 Indexer server with 4 GB RAM and C 60GB, D 60 GB each along with 6 core architecture

1 Database server with two seperate instance and 8 GB RAM and C 60GB, D 720 GB along with 6 core architecture.

Will the above architecture handle the load and have high throughput.


Thanks,

Hardik
