NetApp database sizing tool for sql

[ Edited ]

Hi,

Where can i find the NetApp database sizing tool that's referenced in TR3779, Sizing Guidelines for SQL Server 2005/2008 for NetApp Solutions?  The TR had a link to http://perf-build1.eng.netapp.com/DBSizer/UnifiedDatabase.jsp, but that doesn't seem to work.  Thanks.

This is the correct link for partners:

Thanks,

Re: NetApp database sizing tool for sql

We're a NetApp customer and not partner, so it appears that we don't have access to download the tool.  Any reason why it's available only to partners and not for the customers too.  Is this a downloadable application and is there a way for us customers to get it.

Sorry,  this is for NetApp employees and partners.

You should be able to speak with your NetApp SE or partner SE to have them help you with the sizing tool.

There is a SQL script that we run to gather statistics that I am listing here - there is a variable called WAITFOR DELAY that is set to 10 secs (000:00:10), which I would set for at least 10 minutes.  The out is returns a read/write delta for the time period which we can gain an average for the runtime.  Here is the script:

## Original Create Date: 6/15/05  Original Author: Jonas Irwin
## Current Version: 2.0
## Current Author: Mike Flannery
##
## Purpose:
## Grab IO statistics for SQL Server databases and data files over operator specified time interval
## Mods:  
## 12/20/07 - Flannery - Added UNION at end to make the output more end user readable
## 12/20/07 - Flannery - Tested with SQL Server 2005.  Made tables and columns case consistent
## 3/14/08  - Flannery - Tested with SQL Server 2008
## 3/14/08  - Flannery - Changed SQLIO table from permanent to variable table
## 8/01/08  - Safa . Adjust case in Column calls
## 8/01/08  - Safa . Validate on SQL 2000 and 2005
