Capacity management and sizing for SharePoint Server 2010
Storage and SQL Server capacity planning and configuration (SharePoint Server 2010)
Actually the second article was my starting point for this blog post. The question was – how to size the storage for Sharepoint Server 2010 HA environment? I created an Excel sheet which implemented all rules and advises, mentioned in the resources above. You could download and use it for your projects and of course feel free to customize it. I’ll be very thankful if someone decide to contribute and extend the existing content!
Open it directly from SkyDrive: Sharepoint 2010 capacity planning and sizing sheet
The idea behind this tool is that for each Sharepoint Server 2010 deployment stays a particular business need. Almost always we have a content, which has to be uploaded after deployment and this is our initial data. This data always grows and our sizing and capacity planning approach has to cover this important factor.
General Sites Sizing Sheet
Enter in this section your initial files count and volume in GB
Decide how many initial sites you will have in the farm (one row for each) and divide your initial files between them – as count and as volume.
Define a growth model for each site collection for the next 1 year using the tables. The final size (colored cell) will be auto populated in the above table.
You could find a detailed description of the used formula in Technet
Cell B26 formula: =(B19*B21*B23)+(10*(B22+(B23*B19)))
You can always see the formula details for particular cell from Ribbon/Formulas tab/Formula Auditing group (Excel 2010)
Use the screen shots below, Formula Auditing tools and Formulas in the Excel file to understand the logic of the calculations.
